Professional expertise in water treatment


Brief explanation of key technical terms used in process water, rinsing water, circulation technology, pure and ultra pure water.

Activated carbon filter

Activated carbon filters are used in water treatment to adsorb organic compounds and to remove chlorine and chloramines. more

Bag filter

Bag filters are used in water treatment for separation of coarse particles or for final filtration if the solids concentration is very low. more

Industrial water treatment

Industrial water, also called service water, is used for cooling, production processes or rinsing in industrial applications. more

Dosing equipment

Dosing equipment, sometimes also called dosing station or dosing unit, is used for accurate dosing of products. more


Electrodeionisation (EDI) is a technology which uses ion exchange resins and ion-selective membranes in combination with direct current to remove ions from the water. more

Iron removal filter

Iron removal filters remove iron and manganese from the water. In general, they are filled with catalytic filter material and quartz gravel. more


Decarbonisation units remove hydrogen carbonates of calcium and magnesium (also called carbonate hardness, carbonate alkalinity, and temporary hardness) dissolved in the water. more


Demineralised water is needed in many industrial and commercial processes as well as in hospitals, laboratories and medical technology. more

Ion exchange

Drinking water contains different salts in varying concentration. These salts consist of metal ions (cations) and an acid residue (anions). more

Cartridge filter

Cartridge filters, also called candle filters or fine filters, are non-backwashable protective filters. more

Boiler feed water

Consistently high boiler feed water quality using EnviroFALK water treatment equipment. more

Sand filters

Sand or gravel filters remove undissolved solids (particles) from water or from process fluids. more

Cooling water treatment

EnviroFALK cooling water treatment units ensure safe operation of cooling systems. Cooling systems need large amounts of water in their circuit and for evaporation. more

Multi-media filters

Multi-media filters or multilayer filters remove even the most minute dirt particles from the water by in-depth filtration and adsorption. more

Metal cleaning

Typical tasks performed by metal-processing companies include drilling, milling, turning and welding, which at first sight may not have much to do with water treatment. more


Microfiltration (MF) is used to remove all solids from the water that are larger than the membrane pore size. more


Nanofiltration (NF) is used for partial water softening and for the reduction of turbidity and colouring in surface water. more

Process water

Industrial processes often require specially conditioned water or steam, referred to by specialists as process water. more

Protective filter

Protective filters protect piping systems and downstream units from coarse and fine dirt particles. more

Rinse water treatment

In open systems, rinse water is rejected after use. One way of keeping the cost of fresh water, wastewater as well as any heating energy down, is to reduce the volume of water used. more


Ultrafiltration (UF) is a process where water is filtered by a polymeric membrane with a very small pore size. more


Reverse osmosis

Reverse osmosis is based on the principle of osmosis, which can be observed, e.g., in burst cherries after a summer rain. more

DI water

DI water means deionised water. Deionised water is also called (totally) demineralised water or desalinated water. more

Water treatment unit

Due to scarce resources, impurities in raw or drinking water and consistently increasing requirements, most industrial processes need a water treatment unit. more

Water softening

During water softening by ion exchange, cation exchange resins are used to replace cations such as calcium and magnesium ions, which are responsible for water hardness, with sodium ions. more
