HSB & Activated Sludge Comparison sheet

Activated Sludge Treatment and HSB Microbial Treatment comparison sheet:

Activated Sludge Treatment H.S.B Microbial Method
Large amount of sludge generated. No such problem.
Overall construction costs high and Complex Sewage Treatment Device setup. No such problem.
Low efficiency of Nitrogen (ammonia) and phosphorus removal rate, and the discharge water tends to fail the latest environmental standards. No such problem.
Too many types of heterogeneous microorganisms, COD removal efficiency is low. No such problem.
Difficult to handle volume of toxic substances. No such problem.
Difficult to decompose the organic pollutants. No such problem.
Equipment tends to need a lot of air supply, and causes large energy consumption. No such problem.
Sludge often has “puffing” of enlargement problems. No such problem.
Difficult to remove the smell in the water. (Such as petrochemicals, animal sewage) No such problem.
Microorganisms have high mortality when power failure or HVAV device malfunction. No such problem.
及，，Phenol removal effect is ineffective, and unable to remove color of sewage. No such problem.
