DRINKING WATER FILTRATION SYSTEM FOR VILLAGE POND,WELL

DRINKING WATER AT VILLAGES:

Community drinking water purification plants from surface water sources in case of arsenic and fluoride-affected habitations. 

Pond or wells are the oldest method of groundwater withdrawal for water supply. The water from pond or wells has been found to be relatively free from dissolved arsenic,fluoride and iron.

FLOW CHART :

Pond/well---Pump---Aowal Filter----Pump---- Micron Filters----Activated Alumina Filters----UV Tube disinfection----collection====Supply by 20 Ltr JAR

DESCRIPTION OF PARTS OF THE SYSTEM :

The AOWAL-type sand filter is a low-cost technology with very high efficiency in Iron, Fluoride,turbidity and bacterial removal.

Micron filters remove Turbidity efficiently.

The Activated Alumina Filter removes both Arsenic and Fluoride.We can remove this filter if  inlet Arsenic and fluoride content is within permissible limits. This will make our system completely chemical free.

UV Tube disinfects the water before supply.

We work with local NGO partners in both rural and urban areas to implement lasting solutions to water and sanitation issues and provide training.We are looking for PARTNERING with local NGOs.The NGOs can earn on a MONTHLY basis.The water filtered can be supplied in 20 liter jars at a rate of Rs.one per Liter.Expenses is 50 p/lit,  So a Profit of 50p/liter is obtained.

This model can generate employment and provide clean drinking water to an entire village or an urban settlement.  Local MLA or Gaon Panchayat can fund the project.


Case Study:
Source of Water : Pond, Well
to provide 8-10 litres per capita per day (LPCD) of safe drinking water for drinking and cooking purposes in areas affected by fluoride, arsenic, heavy metals and pesticides. 

Quantity: 3000 Liter per day (For 300 persons @10 liter per person per day ).

Project Cost.: .Equipment cost will be around Rs. Three Lac.



To design a system we need

1. The total quantity of water to be treated

2. A water test is recommended of the following parameters
.

	Source of water	Pond/well
1	pH
2	Turbidity(NTU)
3	TDS
4	Total hardness as CaCO3
5	M-Alkalinity as CaCO3 7
6	P-Alkalinity as CaCO3
7	Total iron as Fe

10	Ammonical nitrogen as NH3
11	Nitrate nitrogen as No3
12	Fluoride as F
13	Sulphate as SO4
14	Calcium as CaCO3
15	Ammonical nitrogen as NH3
16	Arsenic
17	Coli form(Bactoriology tests)

How ENVO was born

ENVO IS MY BRAND & WAS BORN ON 1994. THE FOLLOWING IS THE STORY OF ENVO.

My career began with my respected Uncle  Prof Dr. A.F.S.A.Aowal, I learned the ABCD of  waste water treatment from him. I was working under him as part time lecturer at Delhi college of engineering, Kashmere Gate,Delhi .

Also, I was working as design engineer in National Associates, Delhi. I was staying in 27,Hayat manzil, Basti hazrat nizamuddin, delhi at that time.

ONE FINE MORNING IN 1994, I FOUND MYSELF ALL ALONE. EVERYONE WORKING WITH ME AT NATIONAL ASSOCIATE DESERTED ME WHOLESALE. 

That first kick stunned me for three days and I sat at banglawali masjid (Headquarter of Tabligh Jamaat) at basti Hzt nizamuddin for three days to find out my own roots. A few like my Father  Syed Ishtiaque Ahmad saheb,  Prof Dr. Rashid Hayat Siddiqui saheb of AMU, Dr Chandra Prakash Ji , Vipan Kundra Ji etc gave me "MORAL" support. And M/s Syed Envo Protect (India) Pvt Limited, New Delhi was finally born in 1994....the ENVO brand was born in 1994. Mr.Vipan Kundra, my CA was one of the share holders.It is Vipan kundra ji who gave and registered the name Syed Envo Protect (India) Pvt Limited even without consulting me,because I  was in Assam at that time. He told me that one day I will become international ,thats why he added india to the name. 

 Later I opened one another company by the name of Envo Projects, New Delhi which is still continuing by the grace of God when the private limited company was dissolved due to various reasons.

I received my first career break of my company Syed ENVO PROTECT (I) PVT LTD , a  consultancy at rupees five thousand only at M/s Shade and colors in okhla industrial area phase –I of owner Mr.Deepu Marwah. It’s a cloth dyeing factory.

I left my part time lectureship job in Delhi college of engineering, kashmere gate, delhi  just to concentrate on my own company ENVO. Each and  Everyone called me "lunatic" at that time as nobody was doing full time consultancy in water and waste water treatment in 1994, almost everyone had a govt job. Only gupta ji of Ghaziabad and a few are in the market as full timers. So i jumped  at a completely unknown thing with full confidence in GOD AND MYSELF.At that point of time nobody imagined that this pollution control sector will grow such like this. I created a tag line for my company “THE POLLUTION CONTROL PEOPLE” which i still use in my letterhead.

Many companies are created later on with my credentials and full support by the grace of God. Now i have taken it for granted. I mean, its natural to have a new team after each two three years.So i never try to stop people,anyway they will go , so let them go and try their own luck, good for them, good for me also..But this time as a safety device  i have retained my own company "Envo Projects" under my sole control (Owner) so that i can fall back. People always learn from mistakes. Life is the best teacher.

AND NOW TODAY(09/10/2011), FROM MY HEART I  THANK ALL MY CO WORKERS WHO ARE WITH ME NOW AND WHO LEFT, WITHOUT THEIR BLOOD AND SWEAT ENVO PROJECTS WOULD NOT HAVE BEEN WHAT IT IS TODAY.BECAUSE ITS MY LEARNING CURVE TOO. I ALSO MADE MANY MISTAKES DURING THE GROWTH AND LEARNED FROM IT.

Change your attitude towards life. Do not look for perfection and CONTROL in everything in life. I understood that my livelihood (RIZQ)  cant be  taken away by  anyone.  Put your  best  efforts in what you do and than leave the result to ALLAH. I have plan but Allahs plan is much much better than mine. I have firm belief in ALLAH.  

 

During this journey many people came and left me. I thank all of them for their contribution for my growth. They are destined to be with me for that particular period. This is Allah’s plan.

 

Always sleep with a clean heart. I know many of us get wronged throughout the day or have gotten wronged in the past. Forgive. Not only forgive, but forgive and forget. Dont even hold a grudge against that person in your heart. Keep your heart completely pure.Forgive brothers and sisters before you sleep each night. this is one of the practices of the greatest people ever to live and this is how we will reach those highest levels of spirituality.

 

Forgiveness is good for your own well being, its about giving yourself permission to let go of the painful past. Forgiveness is not something we do for that particular toxic person,it is something we do for ourselves so we can move on to a better future.We forgive,not because that toxic person deserves it,but because we deserve peace, for a pure heart.

Effluent Treatment Plant- Case Study Bone Rendering Plant

Dear Sayeed,

Thanx for the info. I hope you continue to send such valuable info which slips my eye

pls note following points please.

1. The process you sent is primary treatment which is to be followed by MBR or Constructed WETLAND which we have not provided anywhere yet.

In The primary Treatment,  we have not provided UASB.  And then the foaming problem is the biggest.We have not found a solution to the foaming problem yet.

in the flow chart :

2.Balance Tank :We have a balance tank and using lime there to balance pH. NaOH is already coming mixed with water, so no need to add additional NaOH

3. DAF Unit: we are already using Ferrous sulphate, sulphuric acid and PAC there (Polymer) in  DAF.  Dosing is yet to be optimised. 

4.Denitrification:It is done in UASB tank.UASB is missing in Ashrafi and is to be added.We can convert the existing collection tank after DAF into Anaerobic condition by closing the open Top..In Malhotra,we are going for UASB tanks.

5.Nitrification: It is done in the Aeration tank.We have found an anti foaming agent from Ion Exchange by the name INDOFOAM1500, let us try that.Silicone defoamer is not working.We have not found a solution to the foaming yet..We have not used phosphoric acid in the aeration tank.This is a new info.We will try concentrated phosphoric acid when we visit kanpur this time insha Allah.

6.Ultra filtration:In its place we are using Pressure Sand filter.

These primary treatment units are to be followed by a MBR unit or a  Constructed Wet lands unit .After this water can be reused.... ZERO Discharge.

Thanx again for sending such a beautiful article.

Oil & Grease	10 mg/L
BOD	30 mg/L
COD	250 mg/L
Bio-assay Test	90% survival of fish after 96 hours in 100% effluent

These limits are applicable to those hospitals which are either connected with sewers without terminal Sewage Treatment Plant or not connected to public sewers. 

For discharge into public sewers with terminal facilities , the General Standards as notified under the Environment (Protection ) Act, 1986, shall be applicable . Click here to see the General Standards(Schedule VI) 

Main parameters are given below:

PARAMETERS	PERMISSIBLE LIMITS
pH	5.5-9.0
Suspended Solids	600 mg/L
Oil & Grease	10 mg/L
BOD	350mg/L
Bio-assay Test	90% survival of fish after 96 hours in 100% effluent

DPCC has taken decision that Hospital having 50 beds or more shall install Effluent Treatment Plant (ETP) for the treatment of waste water generated and for recycling of treated effluent for use in horticulture, air conditioning/ cooling plants and flushing of toilet etc. 

. http://www.mjmsr.net/article.asp?issn=0975-9727;year=2013;volume=4;issue=2;spage=99;epage=106;aulast=Biswal

In hospitals that have ETP facility, the treatment is carried out using special scientific process and generally involves three stages, primary, secondary, and tertiary levels of treatment. ^[14]

 Average water consumption 750 liter / bed / day (International norm). Please calculate daily water consumption from borewell to over head tank using water meter. 80% of total water in nover head tanks is wasted as waste water. This should be the capacity of the STP to be installed at the hospital. (See table below)

Capacity of overhead tank from where water is distributed = A Liter
Number of times Over Head Tanks Filled up in a day = B Nos
Total water requirement for use at different points = A x B Liter/day
Quantity of Effluent , liter per day = 80 % of ( A x B )

Sourcess of waste water

1. Bed in Hospital= Nos @ 500 liter per bed (DPCC norm)= Liter

2. Employee in Hospital = nos @ 40 liter per employee= Liter

3. Hostels- Persons = nos @ 150 liters per person. = Liter

4. Kitchen Meals= nos@ 10 liter per meal = Liter

So, Total Quantity of discharge: --------- liter per day

Health Stream Literature Summary - Issue 46 - June 2007

The treatment of hospital waste water: an appraisal

Pauwels, B. and Verstraete, W. (2006) Journal of Water & Health, 4 (4) 405-416.

PRE TREATMENT:

Chemical treatment usually involves the use of 1% sodium hypochlorite solution with a minimum contact period of 30 min or other standard disinfectants like, 10-14 gm of bleaching powder in 1 l water, 70% ethanol, 4% formaldehyde, 70% isopropyl alcohol, 2 5% povidone iodine, or 6% hydrogen peroxide


Primary treatment

Consists of temporarily holding the sewage in a basin where the settled and floating materials are removed and the remaining liquid subjected to secondary treatment. Primary treatment usually removes from 30 to 40% of the BOD. After this treatment the BOD and COD levels usually comes down to 25% of its initial levels.

Secondary treatment

Removes the dissolved and suspended biological matter and is typically performed by indigenous, water borne microorganisms in a managed habitat. This treatment uses microbial degradation, aerobic or anaerobic, to reduce the concentration of the organic compounds. The combined use of primary and secondary treatment reduces approximately 80 to 90% of the BOD. In this stage, there is settling down of the suspended solid contents of the biological waste as thick slurry called sludge, while the treated fluid undergoes tertiary treatment. Through this process, 95% of the pollutants from the waste water are removed.

Tertiary treatment

Uses chemicals to remove inorganic compounds and pathogens. This is the final stage of treatment where the effluent after secondary treatment first is mixed with sodium hypochlorite and then the effluent is passed through dual media filter (DMF) and activated carbon filter (ACF) where sand, anthracite, and activated carbon are used as filtration media. Finally, the treated water is let into a small well to recharge the water table. This treated waste water now can be used for gardening, toilets, and laundry purposes. ^[15]
