The quality and scarcity of our water today require water treatment

Even with a good water source, water treatment should be considered to ensure a good water quality.

Water treatment describes those processes used to make water more acceptable for at desired end-use and to ensure that stringent quality standards to the consumer are maintained. Based on several water sources like surface water, ground water and sea water, we combine our knowhow of many technologies within water treatment, such as softening, RO, Ultra Filtration, rehardening, filtration, EDI etc., thus providing all steps from pre-treatment to post-treatment.

Guldager‘s water purification solutions are very flexible and thereby highly adaptable to customer requirements.



Water softening is the reduction of the concentration of calcium, magnesium, and certain other metal cations in hard water.



Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane.



Our side-stream filtration protects equipment and ensures continous effieciency of the cooling water system.



Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane.



The Legionella bacterium may cause the legionary disease, which is a serious form of pneumonia, often with a concomitant effect on other vital organs.



Guldagers antifouling units prevent sea water intake system, lift pumps, pipe systems, filters and heat exchangers from being clogged with mussels, barnacles and slime.
