Processes and techniques are described for treating waste water (domestic and industrial) to remove organic matter and heavy metals. Clay and flocculating agent are added to the waste water to cause separation of a sludge. The sludge is fired at high temperature in particle form to produce ceramic particles. Organic matter is oxidized; heavy metals are bound within the ceramic particles and cannot leach out. The ceramic particles are useful as aggregate (e.g., in concrete) and in landscaping.
