Municipal Water Treatment


In many countries increasingly stringent environmental standards for water and wastewater treatment are being introduced. This development puts growing pressure on existing facilities for the treatment of potable and process water, industrial effluents, sewage and the resultant sludge.

Ciba supplies high efficiency chemicals designed specifically for use in municipal sewage and effluent treatment. We offer a complete series of highly effective flocculants which have been specially designed to rapidly and efficiently separate solids from liquids. We serve a diverse range of industries from petrochemicals, pharmaceuticals, and textiles, to food manufacturing (dairy, sugar and brewery) and agriculture. Our complete service package is designed to protect the customer's investment in the water circuit and ensure reliable process operation.

Potable Water Treatment


We supply high efficiency chemicals designed specifically for use within the municipal potable water treatment sector.

A complete range of products and equipment, together with a commitment to service, enables us to provide our customers with a range of solutions specifically tailored to their needs. Our products include flocculants and coagulants for solid liquid separation processes.

Ciba's lineup of coagulants has been specially designed to rapidly and efficiently remove difficult impurities from water. Coagulants are generally used to separate out impurities such as turbidity, color, oil and grease, phosphates, TOC, and similar impurities. The Ciba coagulant line includes a product range which is NSF certified potable grade and complies with ANSI/NSF 60 standards.

We also design and supply equipment for pre-treatment and product preparation. Our total service package is specifically designed to finding solutions, which protect the customer's investment in the water circuit, and ensuring the reliable process operation.

Dredging has become an industry vital to the protection of the world's waterways, and the 21st century is presenting new challenges. Ciba recognized early on the need for new solutions in the dredging industry by developing and offering tailor-made and cost effective solutions to growing dredging issues. Our products can enhance solid/liquid separation, improve thickening and dewatering and substantially increase the clarity of recovered water in dredging applications.

The removal of contaminated sediments for environmental reasons continues to grow in importance. Ciba has launched a product range that has been specifically designed for the dredging industry. The Ciba® KRYSALIS® range of products clearly enhances solid/liquid separation in dredging applications.

While the number and magnitude of dredging projects continues to increase worldwide, disposal areas for the dredge sediment are becoming more limited. KRYSALIS® dredging polymers applied in both thickening and de-watering process improve the speed and efficiency of water separation thus saving time and disposal costs.

For a more detailed description of the KRYSALIS product range, see our Product Catalog, or click here. (Link to document: KRYSALIS Range overview.pdf)
