Treatment of effluent and sludge
Milk of lime neutralises acid effluent and removes heavy metals in treatment plants for industrial effluent. Thus the process water can be returned to the water circulation. Users include a whole variety of industries, such as the silicic acid and silicone industry, as well as producers of printed circuit boards. In hundreds of municipal sewage treatment plants, FELS lime not only serves to dewater and minimise the volume of sludge produced. Through its hygienic action, it also produces a valuable and safe fertiliser of secondary raw material. FELS application engineers are European leaders in adjusting the balance of lime and carbon dioxide when purifying household sewage.
Biological sewage treatment processes can be stabilised and efficiently controlled by creating an adequate acid capacity or loading the activated sludge with hydrated high-calcium lime. At the same time, the quality of rivers and lakes as a habitat for micro-organisms is improved with a lime-based buffer against acids and alkalis.
