Plastics for safe water treatment

Fresh, clean water is a precious commodity. The efficient sourcing and treatment of water is vital for our quality of life. Sodium hypochlorite, chlorine and ozone are among the aggressive chemicals used for treatment. Installations must be able to withstand these influences for the long term. We offer plastics that are designed specifically for these requirements: they have a high resistance to chemicals, have the necessary purity for contact with drinking water and are easy to process. You can use them to design safe and long-lasting installations. We offer a complete system comprising of sheets, U and hollow profiles, welding rods and the RITA tank construction programme.

Your advantages

  • High operational reliability thanks to very high resistance to chemicals
  • Compliance with standard guidelines: KTW approval, EU Directive 10/2011, FDA, RoHS
  • Suitable for outdoor use thanks to high UV resistance
  • Very easy to weld and process

Typical areas of application

  • Chemical water treatment
  • Purification systems
  • Mini purification systems
  • Drinking water tanks
  • Wastewater treatment
  • Fountains, fountain linings
  • Sea water desalination plants

Product examples

Industrial tanks for water treatment

Tanks made of Polystone® G black HD (PE-HD) for industrial water treatment withstand the aggressive chemicals used in the process, thereby enhancing the reliability and safety of the process. More information about Polystone® G black HD (PE-HD)

Lining of a storage tank for drinking water

With a colour close to RAL 5015, our Polystone® G blue HD (PE-HD) material is particularly suitable for applications in the drinking water sector. The material has KTW approval, is suitable for contact with drinking water and meets the requirements of EU Directive 10/2011.

RITA tank construction program

Developed in close collaboration between Röchling and TÜV-Nord, the RITA®3 (Röchling Integrated Tankbuilding Assistant) program configures upright, unpressurized tanks in round or rectangular form in compliance with current DVS standards. More information about RITA®3

Arrange technical advice

The performance and service life of materials used for water treatment are influenced by a variety of factors. These factors must be taken into account in order to select the right materials. Examples:

  • Type of chemical media
  • Contact with drinking water
  • UV radiation
  • Static loading
  • Design conditions, dimensions and tolerances
