Sewage Treatment
Conventional treatment of sewage requires the setting up of a sewage treatment plant consisting of several tanks having aerators, bio reactors, sludge settling, filtration etc. This activated sludge process leads to generation of sludge and requires filtration. There is a proliferation of anaerobic bacteria resulting in generation of bad odors like hydrogen sulfide and methane. Sludge cleaning and disposal is a big problem. The treatment requires technical manpower, requires POWER is very expensive and it is difficult to achieve the acceptable standards for treated water.
We give below a NEW PATENTED process to treat sewage and domestic effluents with the following benefits.
- No requirements of POWER and SPECIAL EQUIPMENTS.
- No technical manpower is required.
- No sludge generated in the process
- No bad smell generated in the process.
- No expensive chemicals required for treatment.
- Treatment is economical and affordable.
- Treated water passes the tests of the pollution control board.
Protocol for Treatment
For 1 lakh liters of effluent per day, if you have 4 tanks of 50,000 liters each and water overflows from 1st to 2nd to 3rd to 4th then follow the steps given below:
- Install LED lamps of 20W to 40W fitted over each tank.
- Initially bring 20 liters of open Lake Water (to get spores of diatoms). To 5 liters of this Lake Water, add 50 ml Nualgi Lakes and add this to Tank No. 1. Take another 5 liters of lake water, add 50 ml Nualgi lakes and add this to Tank No. 2. Similarly do the same for Tank 3 and Tank 4.
- The bad smell of hydrogen sulfide should stop within 1 day. If not repeat step 2 again.
- Once smell is gone,every day prepare a solution by adding 50 ml Nualgi Lakes to 5 liters of ORDINARY water. Add this solution to Tank 1 ONLY.
- Observe the bubbling of oxygen in every tank.
- You can increase or decrease the quantity of Nualgi Lakes based on observation of oxygen bubbling. If it is more you can reduce Nualgi.
- After about 5 days introduce fish ( about 20 fingerlings Carps or tilapia) into Tank No. 4
- For higher quantity of sewage effluent, increase the tank size and dozing of Nualgi proportionately.
- The water in Tank 4 where fishes survive is the criterion used by pollution control board to assess and confirm treatment efficiency.
