What is sludge (industrial waste)?

Sludge is a type of substance wherein suspended solids either settle or float in water to create muddy chunks. This type of industrial waste is generated through the course of water treatment process in various industrial activities. There are two types of sludge: organic sludge and inorganic sludge. The former is generated by treatment facilities that treat organic contamination in wastewater; for example, sewage, food production, paper-making and pulp mills. The latter type is generated by wastewater treatment facilities that treat wastewater containing high volumes of sand and metal components such as civil engineering sites, water purification plants, and metal plating plants.

・ 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?

・ 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?
