Leachate defoamer: solving foam problems and ensuring efficient treatment
ABOUT LEACHATE DEFOAMER
Foaming is often a major challenge during leachate treatment in landfills and waste incineration plants. Foam not only affects the normal operation of the treatment equipment, but also may lead to environmental pollution and safety hazards. In order to effectively solve this problem, leachate defoamers have emerged.
WHY IS THE WASTE LEACHATE FOAMING?
Complex water quality: Aerobic organic pollutants, various types of metals and the interaction of the surrounding environmental factors can easily trigger foam.
Long-term fermentation: garbage accumulates for a long time, and layer by layer fermentation produces concentration of liquid wastewater impurities, while a large number of bubbles are also accompanied.
Surface viscosity and bacterial imbalance: wastewater decomposition surface viscosity is too high, if the fatty acid excess, the system has a long sludge retention time, low reflux rate, low F/M ratio to promote the excessive growth of filamentous bacteria, which in turn produces foam.
WHAT ARE THE DANGERS ASSOCIATED WITH BUBBLES?
Obstructed discharge: Foam causes waste leachate indicators to be substandard and cannot be discharged normally into urban sewage treatment pipelines.
Difficulty in treatment: Suspended matter accumulates, which is extremely unfavorable to membrane filtration treatment and harmful gas emission.
Damage to equipment and environment: triggering serious corrosion and damage to external equipment, causing large-scale pollution of the pool wall and damaging the surrounding environment.
HOW ABOUT WASTE LEACHATE DEFOAMER
Safe and stable composition: silicone-free, oil-free, free of mineral oil, silicone oil and waxes, chemically stable.
Strong defoaming ability: can break foam quickly and has good durability.
Protective film equipment: when used in film processing situations, it causes little damage to the film and significantly reduces the cost of film replacement.
Wide range of application: it has antifoaming activity in a wide range of temperature from neutral to high pH.
Green environmental protection: no pollution, good integration with most systems, can be degraded to harmless components.
Leachate defoamer is composed of polyether, silica, dispersant and stabilizer, with excellent defoamer and anti-foam effect at low concentration, suitable for direct addition at low and high temperatures, and is specially developed for bio-water recycling treatment system. Leachate defoamercan remove biological fine bubbles, large and small dynamic bubbles and viscous liquid without destroying bacteria, fast defoaming, long foam inhibition, low dosage, can be dispersed in water, and good compatibility with liquid products.
The waste leachate defoamer can be applied to most of the biological waste water treatment, pharmaceutical plant treatment, industrial mineral mixture extraction and separation of various water treatment processes, as well as leachate treatment process.
