Nowadays, the rapid development of life has produced a large amount of domestic garbage. During the process of stacking and landfilling of garbage, due to biochemical degradation such as compaction and fermentation, a liquid with a high concentration of organic or inorganic components is produced under the seepage of precipitation and groundwater, which we call landfill leachate.Landfill leachate water quality is complex, containing a variety of toxic and harmful inorganic and organic substances. The concentration of CODcr and BOD5 in landfill leachate can reach thousands to tens of thousands, which is much higher than that of urban sewage. Therefore, leachate cannot be directly discharged into urban sewage treatment pipelines without strict treatment and disposal. of. Landfill leachate generally uses a combination of anaerobic biological filter (IAF) and biological aerated filter (IBAF) as a biological treatment process.

The specific process forms of garbage percolation treatment devices include traditional activated sludge method, stabilization pond, biological turntable, anaerobic fixed film bioreactor, etc. Generally, it will undergo several membrane filtration treatments to remove suspended solids and harmful molecules.

A large number of air bubbles will be generated during this process, which is not only conducive to membrane filtration treatment and the discharge of harmful gases, but also cause the accumulation of suspended solids. Therefore, it is necessary to add a suitable landfill leachate defoamer to eliminate harmful air bubbles.

Our landfill leachate defoamer is specially developed for landfill leachate process, the advantages are:

1.It is silicone-free, oil-free, non-toxic, does not contain mineral oil, silicone oil and wax, and has stable chemical properties;

2.It has excellent foam control ability, can break foam quickly and has good persistence;

3.When used in landfill leachate treatment membranes, it has little damage to the membrane and can greatly reduce the cost of membrane replacement;

4.It has high activity and has defoaming activity at neutral to very high pH value and a wide temperature range;

5.It is environmentally friendly and non-polluting, has a good degree of integration with most systems, and can degrade itself into harmless components in the water treatment system.
