Professional expertise in water treatment
Glossary
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
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
Decarbonisation units remove hydrogen carbonates of calcium and magnesium (also called carbonate hardness, carbonate alkalinity, and temporary hardness) dissolved in the water. more
Demineralisation
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
Microfiltration (MF) is used to remove all solids from the water that are larger than the membrane pore size. more
Nanofiltration
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
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
