Leachate defoamer

  Treatment of landfill leachate (leachate) is mainly composed of the internal water content of waste and the water generated by the natural degradation process of waste and the water invaded from outside. The high content and variety of internal pollutants, higher COD values, ammonia nitrogen concentration and color are high, making it a more difficult water system to treat. A large number of bubbles are generated due to the different mechanical equilibrium produced by the higher number of active substances.
Hazards of waste leachate bubbles.

It may lead to the failure of the index to be discharged properly into the city's sewage treatment channel
Causes the accumulation of suspended matter, which is not conducive to membrane filtration treatment and the discharge of harmful gases
Serious corrosion and damage to external equipment and extensive contamination of the tank walls, causing serious adverse effects on the surrounding environment

In order to solve the negative impact of such foam, defoamer must be added to solve the series of problems caused by foam. And the waste leachate treatment project involves a number of sections, considering that it cannot affect the later sections, the defoamer should meet the requirements of not affecting the construction process of each section. In summary, we recommend the use of leachate special defoamer.

Product characteristics.
