Industrial water treatment

Solutions for water treatment, recovery and supply

The availability of process water plays an important role in industry since virtually every production process requires water. Whether it is for cooling, cleaning or as a starting material for aqueous solutions – depending on the application, the unwanted substances must be removed from the raw water or the desired substances added.

This task is performed by water treatment plants, thus ensuring a functioning circuit. The GEMÜ product range can provide reliable solutions for components for measurement and control systems for these plants. 

A huge variety of valve types and automation components

Durable, robust and optimised for their specific use: GEMÜ produces and supplies butterfly valves, diaphragm valves, globe and control valves, ball valves, as well as components for plant and plant sections for industrial water treatment.

Examples of processes employing GEMÜ valves, measurement and control systems:

  • Treatment of drinking water via ultra-filtration, ion exchangers or UV disinfection
  • Treatment of process water in the chemical, metal and maritime industry
  • Treatment of waste water in electroplating
  • Control and regulation of heavily contaminated sea, river and brackish water
  • Control and regulation of cooling and heating circuits 

Reliable use for drinking water

At GEMÜ, we only use carefully selected materials and our quality management system ensures continuous monitoring. External institutes such as the DVGW (German Technical and Scientific Association for Gas and Water), ACS (Certificate of Sanitary Conformity), WRAS (UK Water Regulations Advisory Scheme), Belgaqua and, for applications in the maritime industry, DNV-GL, also testify this quality.

Product advantages associated with the use of diaphragm valves with plastic lining

  • All mechanical components are located outside the media-wetted area
  • Suitable for inert and corrosive liquid and gaseous media
  • Suitable for use with both clean and abrasive media 
  • Control functions possible

Product advantages associated with the use of plastic or metal ball valves

  • Good flow capability
  • All plastic media-wetted parts for plastic ball valves are also optionally available in a thermoplastic material
  • ATEX, TA Luft (German Clean Air Act) versions and versions suitable for vacuum applications are optionally available for metal ball valves

Product advantages associated with the use of globe valves 

  • Suitable for fast cycle duties and high switching frequencies
  • Highly suitable for use as control valves in conjunction with suitable positioners
  • Versatile accessories and ATEX versions or versions suitable for vacuum applications are available

All GEMÜ valves with pneumatic or motorized actuator are available with instrume
