wastes
Agriculture

3. Problems caused by Pollution
Putrefaction of organics – generation of methane and hydrogen sulfide gas. Bad odor. BOD and COD.
Growth of pathogenic bacteria- Diseases
Waters with BOD cannot be used for irrigation since plant roots need molecular oxygen.
Breeding of Mosquito larvae
Contamination of ground water.

4. Problems ….. Proliferation of blue green algae. Drop in fish growth.
Pollution in Oceans helps growth of dinoflagellates (red tides) and jelly fish not finfish.
Water cannot be used for drinking or other purposes without treatment

5. CLEANING POLLUTED WATERS
Organics having BOD &COD
POLLUTION
ANAEROBIC BACTERIA
Bad Smell
Incomplete Treatment
Pollutes Ground Water
AEROBIC BACTERIA
Complete Treatment
No bad Smell
Requires Oxygen

6. Current methods of treatment
No treatment : Anaerobic bacteria generate Hydrogen sulfide gas and methane- Stink-- Nitrates , nitrites and organics in ground water.
Treatment: Sewage treatment plants
Aerators – Oxygen --Activated sludge process –Aerobic bacteria – Sludge removal
Investment—Power--Running cost--Capacity restriction--Location and land

Nualgi Technology
11LTR
1 LITRE NUALGI FOR 4 MILLION LITRES OF WATER
Photosynthesis
Diatom Algae grows in water
Zooplankton and fishes clean up the water body.
Aerobic bacteria breaks down organics
Produces pure oxygen by Photosynthesis
under water

8. Nualgi Technology - Benefits
Cleaning polluted lakes, rivers, Oceans
Global carbon sequestration
Repopulating rivers and Oceans with fish.
Mosquito control
Boosting low cost and high productive agriculture.
Growing nutritious food and health benefits.

Case Study Of Nualgi Based Treatment at
Sahibabad Drain, Ghaziabad, India
Started On 8/10/2015 for 3 months

11. Sahibabad Drain @ Brij Vihar Dosing of Nualgi (Diluted in water)

12. Observations post Dosing Bubbles of oxygen rising to the surface and creating ripples on the surface

13. Sludge at the bottom tends to rise to the top and break down due to aerobic bacteria
