SF#07 Sustainable Water Treatment and Recycling in Clay Brick Production

Rain water, storm water, grey water, ground water and water reclaimed from manufacturing processes can be treated and reused.

In the brick production process, recycled waste water can be used during extraction of the clay, mixing and kneading as well as in the factory buildings for purposes such as toilet flushing.

Depending on the nature of water pollutants and end-use requirements, three waste water treatment methods can be used. These are physical, biological and chemical methods. The most feasible water treatment methods to recover water for production processes are the physical and biological methods and these are discussed below. The chemical methods are primarily used to recover waste water for high quality applications such a pharmaceuticals.
