WPM uses the HYDREX range of internationally formulated products to help maintain cooling  & heating efficiencies within many varied client applications. Further HYDREX chemical is used to treat incoming streams of water for various forms of treatment including pre treatment to specialized water conditioning plant.

Boiler Water Treatment Chemicals

Hydrex 1000 series: Used to control scaling or corrosion conditions within heat exchange water circuits. Specialty chemical products used to control the scaling and corrosive conditions that are prevalent in most boiler water systems. Controlling scale and corrosion is critical to ensure internal boiler integrity and safe operations at cost-effective parameters are maintained.

Cooling Water Treatment Chemicals

Hydrex 2000 series: Used to control scaling or corrosion conditions within heat exchange water circuits. Specialty chemical products used to control the scaling and corrosive conditions that are prevalent in most cooling water systems. The BHP Billiton Hillside Smelter is a good example of a large cooling system used to control the furnace temperatures, through water treatment maintaining specific water qualities and conditions.

Flocculants and Polymers

Hydrex 3000 series: Mostly used for potable water clarification in bottling plants and sewage water treatment. However, the company also offers flocculants for industrial and mining applications, i.e. underground settling flocculants.

Chemicals for the optimization of membrane processes

Hydrex 4000 series: Used in reverse osmosis plants. Most of VWS Envig's products have international membrane suppliers' approval for use with their membranes, i.e. Hydraunatics, Dow.  

Membrane Plant Maintenance and Cleaning Chemicals

Highly specialized products, with international membrane manufacturers' approval.

Industrial Maintenance Chemicals

Hydrex 5000 series: Used mainly for cleaning fouled surfaces, such as scale build up in heat exchangers, descaling of boilers, etc. Also have products for pH control in mining applications, of mine water streams

Biocides - Algae and Fungi control in Cooling Water Systems

Hydrex 7000 series: Biocides formulated for bacterial, algae and fungi control in cooling water systems.
