ENVO IS WORKING IN THIS FIELD SINCE 1994. 

An introduction to MBBR (moving bed biofilm reactor )/ FM Reactor/ FAB /FMR Reactor sewage treatment plant (STP)

THIS PLANT IS USED TO TREAT DIRTY WASTE WATER COMING OUT FROM ANY PLACE BEFORE RELEASING IT TO DRAIN. GOVERNMENT DOES NOT ALLOW UNTREATED DIRTY WASTE WATER TO BE RELEASED TO DRAIN DIRECTLY WITHOUT TREATMENT, IT IS CALLED WATER POLLUTION.

WHERE THIS PLANT IS REQUIRED

   1. Land development-housing colony, hotels,Restaurants, resorts, office      complexes,Multistory Buildings, Malls

   2  Schools,College, Hostel, Hospitals,Nursing Home, 

   3.Parks, other recreational areas

   4.  Rail Station,Public places 

   5.Biological treatment for industrial effluent

CHARACTERISTICS OF DIRTY WASTE WATER COMING TO STP:
pH --8
TSS--300 ppm
Oil & Grease --50 ppm
BOD--250 ppm
COD 650 ppm

CHARACTERISTIC OF TREATED WATER GOING OUT OF STP TO DRAIN

pH --8

TSS--less than 100ppm
Oil & Grease --less than 10 ppm
BOD--less than 30 ppm
COD less than 250 ppm

ENVO COMPACT MBBR STP  is a complete unit, pre-piped, pre-wired and ready to install. Engineered to serve with minimal maintenance, and designed to meet the requirements of the state water quality agency. Epoxy or other chemically resistant coatings, together with dependable accessory equipment assure long life and low maintenance cost. And the best part is the resale value. These total units can be re-located to serve again.

o   Branded electrical/mechanical equipments used

o   Good resale value

The Process of Treatment

Primary Treatment (DEWATS/Collection tank before COMPACT MBBR)

In primary treatment, floating and suspended solids are settled and removed from sewage by bar screen. Following this, discharge from the sewers enters a DEWATS/collection chamber .

Secondary Treatment (COMPACT MBBR )

This is the next level treatment where the bacteria in sewage are used for further purification of the sewage. It’s a biological process that removes about 85% or more of the organic matter in sewage compared with primary treatment, where the purification level is about 50%. These processes are variations of what is called the "Activated Sludge" process, which provide a mechanism for bacteria, with air added for oxygen, to come in contact with the wastewater to purify it.

In the activated sludge process, flow from the sewer goes into the reactor, where compressed air is mixed with sludge in the presence of synthetic media on which the purifying organisms grow and contact the wastewater, removing contaminants in the process. The activated sludge allows bacteria to feed on the "food" provided by the new wastewater in the reactor, thus purifying it.

The flow, along with excess organisms that build up on the media during the purification, then goes to a Tube Settler. Air flows up through the media in the filters, to provide necessary oxygen for the bacteria organisms. Clarified effluent flows to the receiving water, typically a river , after disinfection. Excess sludge is produced by the process and after collection from the bottom of the tube settler it is dewatered, sometimes after mixing with primary sludge, for use as fertilizer, disposed of in a landfill, or incinerated.

Tertiary Treatment

Advanced level of water treatment is called tertiary treatment of water - where heavy metals, toxic chemicals and other pollutants are removed from wastewater to an altering degree. The tertiary treatment methods include micro filtration, carbon adsorption, evaporation/distillation, and chemical precipitation.

SPECIAL FEATURE OF OUR DESIGN:

We provide two-stage treatment. DEWATS is the first stage treatment. Because of DEWATS, the blower capacity is reduced in the second stage of MBBR treatment thereby reducing the maintenance cost during running of the STP..
