Is CLIRAC treated sludge recyclable?

CLIRAC treatment method not only contributes to sludge volume reduction, but also allows to treat and recycle sludge which was once considered untreatable. The following is the result from a dissolution test using CLIRAC.

CLIRAC Method: Sludge Elution Test Result
◎ If targeting for maximum elution of a harmful substance, increase the amount of CLIRAC coagulant agent according to the level of contamination.



The past CLIRAC application examples involve treating dredging sludge from a metal polluted lake. The final product was turned into base material (raising member) for a farm land consolidation site. The other examples utilizing the final product were turf planting soil at a park site, a road slope face greening project, and so on.

・ Petroleum sludge is known to be very difficult to treat, therefore, such sludge is normally left untreated. Is your technology able to treat and recycle this type of sludge?
・ The demand for a new treatment technology has emerged because the current methods suffer from issues with energy-consumption and disposal limitations. Is WEF capable of providing technology to solve these two issues?
・ Pressurized flotation separation process of oil requires a large amount of chemicals in addition to high maintenance and cost for disposing the separated oil substance as industrial waste. Does the SBC-Pro treatment system help solve these issues?
・ Waste disposal is broadly categorized as one of two types, industrial waste or general waste. For general waste disposal, unlike Japan, China and other Asian countries are lacking strict waste recycling regulations, even though their landfill capacities are getting smaller and smaller. We often see photos of children in such countries working and searching for valuables in the waste disposal sites (raw garbage). Do you have any solution to treat general waste without waste segregation?
