Waste Water Management: About 70% of the 8 lakh litres of water supplied to the residents, that is, 5.6 lakh litres of waste water generated is treated in a decentralized waste water treatment plant within the campus using the Moving Bed Bio-reactor (MBBR) technology. There is a net savings of Rs.5 lakhs per annum due to direct and indirect savings from a decentralized Waste Water Treatment plant (WWTP) in the campus whose running cost is Rs.55.55 lakhs as opposed to the centralized sewerage system costing Rs.60.62 lakhs.  

The energy savings from 300 solar street lights at the GPRA complex, covering internal roads, common areas, parking lots and bunglows, help in saving Rs.32.28 lakhs per annum. Along with solar water heaters, the savings on electricity is close to Rs.35 lakhs a year.     

Therefore, a decentralised integrated solid waste, waste water and energy project for about 1000 households can achieve clean and green surroundings and financial savings to the tune of Rs.40-50 lakhs per annum

Quantity of Solid Waste Generation

Considering an average garbage generation per capita per day as 0.450 Kg, we can assume a total garbage generation for a population of 100,000 as 45,000 Kg per day

Landfill Leachate Treatment

Landfill Leachate Treatment

Landfill leachate is generated from liquids existing in the waste as it enters a landfill or from rainwater that passes through the waste within the facility. The leachate consists of different organic and inorganic compounds that may be either dissolved or suspended. An important part of maintaining a landfill is managing the leachate through proper treatment methods designed to prevent pollution into surrounding ground and surface waters

The physical appearance of leachate when it emerges from a typical landfill site is a strongly odoured black, yellow or orange coloured cloudy liquid. The smell is acidic and offensive and may be very pervasive because of hydrogen, nitrogen and sulfur rich organic species such asmercaptans.

If leachates have a distinguishing characteristic, it is that they are variable.  Flows change based on the weather  – increasing during rainy periods, decreasing during dry and waste concentrations can change dramatically over the life of the landfill.   As a result, no landfill leachate is constant over time, and no two leachates are the same.

When the landfill is a few years old the dominated fermentation phase is acidogenic and the leachate generated is generally referred as “young”.In that case, COD and BOD reaches very high concentrations. The ratio of BOD/COD is higherthan 0.7 and pH is low due to the high concentrations VFAs. Landfill grater than 10 years old aregenerally in the methanogenic phase and theleachate generated is referred to as “old”. Duringthe methanogenic phase, bacterias are degradingthe VF-acids and reduce the organic strength ofleachate, leading to the pH value higher than 7.In “old” leachate BOD decreases faster than CODand the radio BOD/COD is stabilized on the levelless than 0.2 [2,4].Anaerobic treatmentprocess is used mainly for young landfill leachate,which BOD5 and BOD5/COD ratio is very high[2]. However, Kettunen, et al. [10] performedthe treatment with UASB reactor were municipal landfill leachate was having COD higher than800 mg × dm−3 and the BOD/COD radio washigher than 0.3.Anaerobic processes of landfill leachate inUASB reactor allow complete removal of CODfrom 65 to 76% and BOD5 removal beyond90% [11].

UNITS OF TREATMENT OF LANDFILL LEACHATE:

1.      Collection Sump: Areas in which rainfall is higher than average typically have larger sumps. A further criterion for sump planning is accounting for the pump capacity. The relationship of pump capacity and sump size is inversed. If the pump capacity is low, the volume of the sump should be larger than average. It is critical for the volume of the sump to be able to store the expected leachate between pumping cycles. This relationship helps maintain a healthy operation. Sump pumps can function with preset phase times. If the flow is not predictable, a predetermined leachate height level can automatically switch the system on. Other conditions for sump planning are maintenance and pump drawdown. Collection pipes typically convey the leachate by gravity to one or more sumps, depending upon the size of the area drained. Leachate collected in the sump is removed by pumping.

LITERATURE STUDY: WASTE TO ENERGY CONCEPTS

Energy recovery as electric power is a feature of all waste-to-energy systems.

Evaluation of the applicability of the technologies of biomethanation, gasification/pyrolysis,incineration and landfilling as Waste-to-Energy options, and their comparison against composting as a competing technology for waste disposal, has shown the following:

• Biomethanation has emerged as a favoured technology for various urban and industrial waste.

• Gasification/pyrolysis have a distinct promise, and although there are limitations to its uptake, these can be overcome as the technology matures.

• Incineration is a mature technology for energy recovery from urban and industrial wastes and has been sucessfully commercialized in the developed countries. The recent focus has been on environmental compliance due to which it will become an expensive option.

• The present trend is in favour of material recovery facilities and a shift away from landfills for MSW disposal in developed countries.

• Compositing is not a WTE option and does not come out as worthwhile waste treatment process.

• Technologies like landfill with gas recovery and composting can become viable options for certain locations in India, as a short to medium term option.

 

Landfill Leachate Treatment Technologies

Landfill leachate may be characterized as a water-based solution of four groups of contaminants ; dissolved organic matter (alcohols, acids, aldehydes, short chain sugars etc.), inorganic macro components (common cations and anions including sulfate, chloride, Iron, aluminium, zinc and ammonia), heavy metals (Pb, Ni, Cu, Hg) , and xenobiotic organic compounds such as halogenatedorganics, (PCBs, dioxins, etc.).^[4]

Leachate treatment technologies fall into two basic types, biological and physical/chemical. In larger systems and depending on the treatment goals, integrated systems which combine the two are often used.
The typical processes used for pretreatment include equalization, aeration, pH adjustment and metals removal.

The most common biological treatment is activated sludge - a suspended-growth process that uses aerobic microorganisms to biodegrade organic contaminants in leachate. With conventional activated-sludge treatment, the leachate is aerated in an open tank with diffusers or mechanical aerators. After the aeration phase, the mixed liquor of microorganisms and leachate is pumped to a gravity clarifier.

The rotating biological contactor (RBC) is an attached-growth, aerobic, biological treatment process in which a series of discs are partially submerged in a tank of leachate. The disks eventually develop a slime layer, then rotational shear forces strip off the excess solids and carry them with the effluent to a clarifier, where they are settled and separated from the treated waste.

The carbon technique removes dissolved organics from the leachate. Although carbon systems may be useful with some older leachates, the cost of the carbon in the regeneration stage can make the process one of the most expensive treatment options.

Advanced Treatment The new landfill regulations have made some treatment systems obsolete. Many landfill operators are now choosing new systems that produce a cleaner effluent and can reduce capital and operating expenses. Such systems include:

* Recirculation and Injection. Direct recirculation distributes the leachate onto the landfill in a semi-closed loop process. While promising, this system has limitations of recirculating 100 percent of the leachate without literally soaking the landfill.

* Membrane Solution. Membrane technology can be adapted to many steps of purification and keep clean-up standards at a high level. Membranes can remove contaminants without extensive biological infrastructure or toxic chemicals.

* Reverse Osmosis (RO). Prior to 1988, reverse osmosis wasn't able to treat leachate successfully due to the core membrane design of spiral-wound modules, which were state-of-the-art at that time. While this method produced efficient results, it also promoted bio-fouling and premature clogging.

Disc Tube technology, developed by the Rochem Group, has been installed in more than 35 European landfills to treat feed waters that would foul conventional RO configurations. After the contaminated water is fed into the tubular chamber, its flow is controlled as it passes through a system of discs and over flat membrane cushions, removing clean water and concentrating the waste material. The turbulent flow reduces the membranes' tendency to scale or foul and requires cleaning less frequently.

The system removes heavy metals, suspended solids, ammonia and hazardous non-degradable organics including pesticides and herbicides without extensive pre-treatment systems. The pure water is clean enough for direct discharge into the environment and accounts for 75 to 92 percent of the leachate. The remaining concentrate can then be recycled to the landfill or further processed.

Siemens Water Technologies' PACT® systems combine biological treatment (activated sludge) with adsorption (powdered activated carbon) so that physical and biological treatment occur simultaneously. The system removes biodegradable and non-biodegradable pollutants in a single process

The most cost effective form of treatment for high levels of BOD, COD and ammonia is intense biological oxidation, and in the UK the sequential batch reactor is the most common technology used. The sequence batch reactor (SBR) is a form of activated sludge treatment.

Granular activated carbon, in combination with biological pretreatment, is a proven and economical technology which is effective in reducing Chemical Oxygen Demand (COD), Adsorbable Organic Halogens (AOX), pesticides, solvents, organic compounds and other toxic substances to the strictest legal National and EC norms. The chemical composition and content of landfill leachate can vary greatly between landfill sites. The age of the landfill, type of waste and treatment processes already in operation are the parameters to be considered.

COD levels can range from 200mg/l to 2000mg/l. Carbon consumption is normally dependent upon the COD adsorption rather than the AOX. Therefore COD will be the determining factor in estimating carbon consumption.

However, an aerobic system must be used after the UASB reactor for the effluent to meet the standards defined for the proposed disposal method.

 

Combined treatment of leachate from sanitary landfill and municipal wastewater by UASB reactors

This study showed the potential of anaerobic treatment in an UASB reactor treating a combination of domestic wastewater and leachate in a 5% volumetric ratio of leachate. Under these conditions the reactor assimilated properly the leachate fraction incorporated. With a HRT of 8 h and a mean volumetric organic load of 2.84 kg m(-3) d(-1) COD removal efficiencies around 70% were obtained,

When installing a leachate treatment system, choose a plan that will provide the maximum amount of long-term flexibility to assure compliance with future regulations and discharge standards.

LEACHATE RECYCLE  CONCEPT :The major objective of gas studies is directed towards maximizing production rates of gas by biodegradation of the waste while simultaneously reducing the period of time that gas is evolved by recycling leachate. It describes potential means of managing both leachate quality and quantity by leachate recirculation to aid in decomposition of the waste while also treating the organic material in the leachate and reducing the quantity of leachate that must be treated and hauled away from the site.

http://timesofindia.indiatimes.com/Its_A_Gas/rssarticleshow/3477605.cms

San Antonio in the United States could become the first city to draw all its energy requirements from methane gas generated from the city's water treatment system through recycling 14,000 tonnes of biosolids in sewage annually. The methane source includes human waste that, if left untreated and unutilised, would only pollute soil and water.

Treating bio-waste, however, could generate an average of 1.5 million cubic feet of gas a day - enough to fill 1,250 tanker trucks daily - according to the system's chief operating officer. A by-product of human and organic waste, methane is the chief component of natural gas that can fuel generators, power plants and furnaces.

Closer home, gobar gas - natural gas obtained from methane released by cattle waste - as a green alternative to diesel and other fossil fuels has been taken up seriously, particularly in rural households. However, a lack of adequate hygiene is a constraint because the gas formation - in the large containers filled with gobar - makes the drum's lid rise, and there is spillage all around the plant. So, in India gobar gas plants are fertile breeding grounds for mosquitoes and other pests. But this is not an insurmountable problem. Gobar gas plants could be expanded and diversified to include energy extraction from all kinds of biomass and the gas so produced could fuel power stations - as San Antonio proposes to do - and with improved sanitation, the experiment could yield good results for several Indian cities.

As a renewable resource, biomass - either from plants, agriculture and forestry residues, animal or human waste - is biodegradable and so is far more eco-friendly than petroleum-derived fuels. And they are relatively easier to source and process, unlike the sophisticated instruments and know-how required to extract oil or refine coal. Ethanol derived from biofuels has a very high octane rating. It might deliver less energy than gasoline, but by blending about 10 per cent ethanol and petrol or diesel together, a feasible balance is achieved with no perceptible effect on fuel economy.

America's space agency NASA is sponsoring a joint project to turn human waste into a power source for spaceships using a process that could also produce other chemicals that can be used on board. Instead of turning up our noses at the idea of recycling human waste and other biosolids in sewage, it would be worthwhile to explore fully and exploit the immense potential hidden in what we routinely regard as being useless.

Bioreactor Landfills

PBS&J is very familiar with a wide range of leachate treatment technologies, including recirculation, in which leachate is transferred from the bottom of the landfill to the top. We have been closely involved with organizations that are refining the process of leachate recirculation to create landfills that are "bioreactors," using leachate and other sources of liquid to maximize the decomposition process and thereby extending the life of a landfill.

Leachate Evaporation and Cotreatment

Landfills that collect and flare their landfill gas have an opportunity to use this energy to economically manage leachate via evaporation. PBS&J assists landfill owners in evaluating the cost-effectiveness of this disposal alternative and in implementing leachate evaporation systems. PBS&J also offers experience in cotreating leachate with other wastewaters, including domestic wastewater and septage.

Here are the latest updates for saleemasraf@gmail.com   " Biogas from Waste Landfill Site to Power Brazilian Refinery - Waste Management World From Newport Beach, California based energy company, FirmGreen, Inc. has made the first international shipment of its biogas cleaning equipment to the Novo Gramacho Landfill near Rio de Janeiro, Brazil. The Novo Gramacho landfill where the project is located has also been depicted in a documentary nominated for a 2011 Academy Awards - Waste Land. In 2010, FirmGreen negotiated an agreement with Brazil's G?s Verde, S.A., which is the project developer and the plant's owner-operator, to turn Waste Land's 'dirty gas,' a natural by-product of decomposing waste, into clean usable gas using the company's proprietary technology. The company claims that the resulting biogas is an environmental-friendly, highly useful fuel with the energy equivalent of natural gas. Petrobras, the largest company in Latin America by market capitalisation and revenue, will use the biogas to generate over 10% of the thermal energy needed to run its Duque de Caxias Refinery. The company claims that using the U.S. government's EPA LMOP calculator the Novo Gramacho Anaerobic Digestion Plant will reduce greenhouse gas emissions by 1.4 million metric toness, annually.. To fabricate the specialised gas cleaning equipment required for the project, FirmGreen contracted with Dublin, Ohio based Guild Associates. Guild employees are also helping start-up Gs Verde's Biogas Plant. Brazilian contractors are manufacturing some of the project's components and will take a lead role in the plant's installation. FirmGreen's CEO, Steve Wilburn, commented, "Our world continues to face significant economic challenges, yet this project demonstrates how bi-cultural teamwork can generate hundreds of jobs, in this case throughout six U.S. states-Indiana, Wisconsin, Ohio, California, Michigan, and Texas-as well as Brazil." The Novo Gramacho Biogas project is slated to begin commercial operations later this year.

The Fund will be administered by WRAP - the Waste & Resources Action Programme - and will lend amounts ranging from £50,000 to £1 million to support the development of new AD capacity in England in conjunction with investment from the private sector. It aims to support 300,000 tonnes of annual capacity to divert food waste from landfill by 2015. Delegates to the conference and exhibition, which is organised by the Anaerobic Digestion and Biogas Association (ADBA), were broadly positive about the funds. But, some had reservations, especially in terms of finance and local authority commitment. In his opening speech on Wednesday (July 6) to the conference, Lord Redesdale, chairman of ADBA, had highlighted the importance of securing feedstock. Responding today to Lord Henley's announcement, ADBA chief executive Charlotte Morton said: "This fund is welcome news for the industry, and will support projects which will make a real difference in starting to build up the UK's anaerobic digestion capacity. Barrier "However, it represents only a small part of the investment which is needed to take AD to the point where it is really delivering for the UK's strategic objectives – and raising finance remains the biggest barrier for projects. "Meeting the UK's 2020 commitments on landfill diversion and renewable energy require high investment in new capacity over the next few years. That simply isn't happening while investors are being put off by mixed messages from government, and while they remain unwilling to direct local authorities to take a course they have already said realises the most benefit. She added: "The Government needs to build on this announcement by grasping the nettle to encourage wider private finance into the market. This doesn't require more money from the taxpayer – simply clear statements that organic waste feedstock should be source segregated and prioritised for AD." Viability Two delegates from the financial sector told letsrecycle.com that, despite the grant, there would still be concerns about the viability of AD plants taking in waste from the household stream. One said: "Projects dealing with farm waste and commercial waste have a more secure feedstock. There are a lot of uncertainties in dealing with waste and even more when comparisons are made to investing in other renewable energy projects, such as wind power." Another added: "Some people in the AD sector seem to expect banks just to jump in and take a risk which we just can't do." And, delegates to the conference also heard a warning from a top local government officer  about the uncertainties that currently exist among local authorities.
