Water treatment

Under the DIVINOL brand, Zeller + Gmelin offers a comprehensive range of water treatment products for the circulation and system water treatment: from coagulants for water-bearing painting systems with settling or flotation discharge systems, to flocculants for coagulation of hydro-paints, to defoamers for water-sprinkled paint.


DIVINOL® defoamers are liquid, highly concentrated products that can be combined with DIVINOL® coagulants for defoaming water-sprinkled paints.

 DIVINOL® defoamers are required when using paints likely to produce excessive foaming in the circulating water of the painting system. DIVINOL® defoamers eliminate foaming, helping reduce contamination in discharge systems, while minimising expensive clean

Paint coagulation

DIVINOL® coagulants are usually liquid products suitable for water-bearing painting systems with settling or flotation discharge systems. The outstanding debonding qualities of DIVINOL® coagulants with solvent-based paints and simple paint sludge, help increase water stand time and minimise the cleaning effort.

Combine DIVINOL® coagulants with DIVINOL® flocculants to discharge particularly complex painting systems by flotation. Use DIVINOL® efoamers to remove excessive foaming produced by particularly foam-heavy paintings.

Cooling water treatment

bactericides are wide-band biocides for the control of bacteria, fungi and algae in industrial cooling water systems.
The other Divinol CWT products are used alone, or in combination for protecting open and closed cooling water circulations or air washers from corrosion and deposits.
Divinol system cleaners/dispersants are products used for conditioning such systems for product or water changes, and are used to remove dirt, oil, dead biomass and lime scale from closed and open systems.

DIVINOL® flocculants are special liquid products for painting systems. In particular,DIVINOL® flocculants are used for the coagulation of hydro-paints. As a rule, flakes produced during use are of a coarse texture, and can be separated easily by filtration, sedimentation or centrifugation.
