What Is Jarikko Purification System? Comparison to Activated Sludge Method River Purification Lake Purification Industrial Wastewater Treatment Community Plant Treatment About Aquatech Contact Us		・Activated Sludge Method separates solids from liquid, therefore, it needs to treat and dispose the sludge. ・Contact Oxidation Method is the same as Activated Sludge Method. ・Because the space ratio of the reaction tank of both Activated Sludge Method and Contact Oxidation Method is over 95%, the inside of the reaction tank is equalized and always in the single environment of aerobic condition. Therefore, decomposition of solid organic matter is impossible. ・A food chain gets formed. ・The space ratio between Jarikkos is 40% and aeration pipes are placed 40cm apart, therefore, aerobic/anaerobic environment differentiation starts happening. ・This action keeps repeating. Eventually, solid organic matter decomposes and becomes gas (CO2 & CH4) and H2O. ・Only aerobic bacteria and anaerobic bacteria participate. Protozoa are not needed. In conclusion, Jarikko Purification System is a new revolutionary technology which does not need a sludge treatment. It replaces the 100-year-old Activated Sludge Method.
