Sewage sludge treatment

Sewage sludge is a by-product of sewage treatment. It takes two forms; semi-solid waste (raw or digested biosolids) and slurry (liquid sludge). Both forms of sewage sludge require further treatment before they can be safely disposed of or recycled. In the agricultural sector, sludge treatment can turn a potentially harmful waste stream into safe and natural fertilizer for use on land.
