Recycling Water From Sewage

02/19/2007 3:30 AM

Please, I like to have some knowledge about the system operation of the compact unit for the purpose of recycling water from the sewage. The project is for a small village about 10,000 population. with best regards

Total sewage discharge from 10000 people would be approx. 135 lit x 10000 = 1350 m3 or 13.5 lakhs lit. There may be two ways to treat the water

1. Electro chemical process

2. Natural Biological Process

First one Installation cost would be approx. $ 1,40,000.00 including pump, blower, filters, UV lamp, resourver etc & Running cost would be approx. $ .1 X 1350 = $ 135 Per day

Second one requires a 3 hp self priming pump, sand filter bank of 03 layers, soil digged pond of suitable capacity, dosing system, green water plants, fishes etc.Cost would be approx $ 35,000.

water may be reused for gardening, flushing, car washing, construction etc. Manure may reused as fertilisers.

Electro-coagulate the high BOD,smelly "Untouchable" water to drinking quality---without any Chemicals/massive Civil Engineering expenses--.

We talked a lot in CR4 about world's "drinking water solution from ANY AVAILABLE WATER"

Village--10000--Electricity--do not be afraid.You will NOT need to use huge KW's

I'd like to learn more about this electric method of purifying water. How do I fing the prior conversation? I recall seeing an amazing product on the telly years ago, on a program called "Beyond 2000". It showed a 'hot tub' looking tank that supposedly purified black water to drinking water, in Australia. They were supposedly installing these things in homes that surrounded poluted Sydney Harbor. Anyone ever heard of these? I tried for quite a while to find out more information but couldn't.

Electrocoagulation is answer to the worldwide pollution problem future .

Also how to " Convert any bad water-including sewage to safest water.

It is how the Science-Technology-Politician community looks at life-will determine the rise of Electrocoagulation to solve all these serious issues -----------------> Simply/Effortlessly/Scientifically.

To Start please go through http://www.powellwater.com/

And if you want to dig deeper Pls. Search Electrocoagulation. Google lists 313000 !

Can We add following too:

Abstract The purification of raw surface water from its organic, inorganic and microbial content using the electro-coagulation method was investigated. Batch coagulation experiments were conducted using the jar-test method. A pair of aluminum electrodes (suspended in the jar) was charged with low voltage current for releasing aluminum ions in the raw water to precipitate the suspended matter. The optimum current density was 0.6325 mA cm–2. The coagulation efficiency was evaluated by determining the turbidity of treated water. The efficiency reduction in raw water turbidity was 90%, leading to a change in water Zeta potential from –85 mV (before treatment) to –40 mV (after treatment), i.e. the particles tended to be destabilized and the coagulation process became predominant. Water contents of nitrates, phosphates and sulfates were considerably reduced by 77.5, 83.3 and 20.0%, respectively. Also, this method is effective in reducing both the total viable bacterial count (TVBC) and total coliforms (TC) by a ratio of 1/104 and 1/103, respectively.
