With our water treatment chemicals and our specialised services, we want to make an important contribution to meeting this challenge by reducing the problems that can occur during water treatment and maximising process efficiency. At Zschimmer & Schwarz, we offer efficient and environmentally friendly additives to improve the performance of both industrial and drinking water treatment plants.
Antiscalants are additives capable of preventing the accumulation of sparingly soluble salts in water. Therefore, they are indispensable products in most water treatment systems.
One of their main applications is in reverse osmosis systems, where they prevent the incrustation of the membranes. However, they are also used in other systems where scalings can lead to a loss of performance, for example in cooling towers.
At Zschimmer & Schwarz, we offer a range of antiscalants that can prevent the formation of sediment and maximise the performance of the system in which they are used. Within our antiscalant range, there are products that have the NSF certification required in reverse osmosis, for example, so they are accredited for contact with drinking water.

A defoamer is an additive often used in industrial processes that is capable of reducing or eliminating the formation of foam in a liquid. Foam formed on the surface of the aqueous phase can interfere with water-based production processes, as it, for example, reduces the heat exchange surface and thus decreases the energy efficiency of the processes.
Zschimmer & Schwarz offers different types of defoamers with different chemical structures to suit your area of application.

Corrosion is a natural process in which a material is damaged by chemical reactions. Although corrosion can be divided into many categories, in the water treatment sector corrosion caused by diatomic oxygen (O2) is predominant: the reaction occurs between metal and oxygen, forming its metal oxide. Therefore, systems containing water, such as closed heat exchange or heat storage systems, require corrosion inhibitors in order to prevent damage to the system.
At Zschimmer & Schwarz, we offer a wide range of corrosion inhibitors that will increase the performance of your system, prevent damage and reduce operating costs.

Dispersants are chemical compounds that are added to a suspension in order to improve the separation between particles. They are needed because, in many cases, water systems contain contaminating solids, which tend to settle.
Zschimmer & Schwarz offers a range of dispersant additives that promote the compatibility of the solid with the water system, thus preventing settling and facilitating its treatment by a solids removal system.
