Leachate Treatment Commissioning
We carried out a commissioning at the site of a waste treatment company in Okayama Prefecture. The target is leachate.
Leachate is water that flows out of landfill sites, which contains substances from rain, snow and the landfill itself.
As landfill is often made up mainly of incinerated ash and non-combustible materials, the water quality of leachate effluent tends to have low concentrations of organic substances such as BOD, but high concentrations of calcium and chloride ions.
The role of the KDS Separator in the plant is to flocculate impurities and separate solids to reduce the load on the next process.

|Wastewater to be Treated||Leachate|
|KDS Products||KDS 611D System + Polymer Preparation System KDS-500|
|Polyferric Sulphate→Activated Carbon→Polymer Flocculant|
|Dewatered Cake Dryness|
The flocculation is first carried out with polyferric sulphate, followed by adsorption treatment with activated carbon and then again with polymer flocculant.
After separation, the filtrate is ozone-treated and the dewatered cake is disposed of as industrial waste.
