Raw Water Treatment

Supplier: Nalco

"Raw" water coming into a plant from a surface source, typically a river adjacent to the site, frequently contains suspended solids that must be removed.

Price Guide: POA

Clay, sand, and silt are among the solids present. Soluble solids such as those created by iron or other heavy metals along with silica, color agents, and organic matter are there, too. "Hardness" of the raw water, caused by the presence of calcium and magnesium salts, is another water quality problem to be treated. Also, microbical life must be controlled or fouling of the system will occur.

Nalco offers a wide range of products and services that help industries properly manage this important resource.
