Aeration tank biological water treatment defoamer is a modified polyether type and pure ether type defoamer synthesized by Nanhui through various special processes. They are silicone-free products developed for all kinds of biological water treatment systems with high efficiency and environmentally friendly non-silicone defoamer. They are suitable for biological slurry, active sludge decomposition foaming, purification foaming, recycling industrial wastewater, biological wastewater, pharmaceutical plant wastewater, aeration ponds, and various biological water treatment foaming processes.
In biological water treatment is the use of microorganisms including bacteria, fungi, algae, and protozoa to oxidize and decompose harmful substances in water into harmless substances. Aeration treatment is an important step in domestic water treatment. In the aeration stage, a large amount of foam will be generated and this foam cannot be eliminated naturally, requiring the addition of biological water treatment defoamer.
The main reasons for aeration pool water treatment foaming are
(1) Aeration volume is too large and oxygen oversaturation.
(2) in the sewage treatment operation the water body will continue to grow a large number of filamentous bacteria and actinomycetes easy to produce a large number of bubbles.
(3) The concentration of organic matter in the influent water is too high anaerobic residence time is too short.
(4) Biological water treatment when aeration or oxygen supply too much foam will affect the progress of water treatment or overflow and affect the active mud and bacteria.
(5) The wastewater is rich in surfactants and other additives.
