What is sludge treatment?

Sludge treatment is a type of technique employed to reduce sludge volume through processes like concentration, dewatering, and incineration, and to convert sludge into a more stable and hygienic condition for easy-handling and reduction of landfill disposal.

The graph below shows a breakdown of the types of industrial waste reported in 2004 per volume. Sludge takes up about 40% of overall waste. Within this 40%, sewage sludge comprises a large part, taking nearly 20% of the overall percentage.



Today, international demand for sludge waste recycling has greatly increased in response to significant landfill shortages; reduction of sludge waste is now a very important global issue.

・ What is industrial waste disposal?
・ What is sludge (industrial waste)?
・ What is sludge treatment?
・ Why is so much sewage sludge generated?
・ Is sewage sludge simply treated by drying, incinerating, or landfilling?
・ Is WEF’s α-Gaia system effective to treat sewage sludge?
・ Do you have technologies other than the α-Gaia system?
・ How can we adopt CLIRAC treatment in our facility?
・ What is the procedure for CLARIC treatment at our site?
・ Is CLIRAC treated sludge recyclable?
・ 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?
