Zero compromise

Good potable water is clear, odour- and taste-neutral, and not too high in mineral salts. It must also meet very high standards of hygiene. ProMinent offers a full range of technologies for disinfection, oxidation, membrane filtration In water treatment, membrane filtration is the process for removing particles and salts in the water ... more in the glossary and desalination. With these technologies, it's possible to achieve very high quality potable water in accordance with global WHO standards.

From Madeira to Thailand

Water needs to be processed differently depending on its origin and how dirty it is. ProMinent has the right cleaning process for every requirement. This is the only way to ensure the best possible quality - anywhere in the world. Whether it's table water in Madeira, potable water for a Swiss town or an immediate water supply for flood victims in Thailand, ProMinent products and mature complete solutions provide potable water of a reliable high standard. Thanks to built-in measuring and control technology, the quality of the water in the treatment systems can be monitored immediately and in situ. This offers the benefits of high operational reliability and low costs for the operator.

Applications - Potable Water Supply

(Sand) Filtration for Potable Water

Filtration removes solids from the water

Unwanted particles and turbidity are removed from the water by sand or membrane filtration. An even more effective process is to filter using upstream flocculation or precipitation. Added substances allow smaller particles to become larger, so dissolved substances can flocculate.

Desalination of Seawater and Brackish Water

Obtaining additional potable water with desalination

Drinkable water is scarce. Only a fraction of all the world's water can be consumed. So the ability to treat brackish water and seawater is of interest to many countries and islands.

Stabilisation of Potable Water

Stabilisation makes water ready for transport

After the water has been treated, its quality should not change. Stabilisation maintains the quality of the water during distribution and use.

Disinfection of Potable Water

Germ-free potable water thanks to disinfection

As an essential nutrient, water must satisfy very strict quality controls. ProMinent offers sophisticated disinfection technology that reliably removes viruses, bacteria and microorganisms.

(Pre-)Oxidation of Potable Water

(Pre-)oxidation binds harmful substances in potable water
