Industrial water

Raw water extraction from the region

Industrial water, also known as industrial process water, is often taken directly from nature as raw water. It can come from natural springs, rivers or lakes or be collected as groundwater or rainwater.

Depending on where it is drawn from, the raw water may be contaminated with dirt, bacteria or harmful substances. As the water must also meet minimum standards when used in industrial processes, it is pre-purified or softened to meet the requirements of the respective production and - for example, when used in fire extinguishing or cooling water systems - filtered in several filter stages.

In high-quality production processes and for steam generation, industrial water featuring a purity close to drinking water, pure water or fully desalinated water is used. Regular sampling ensures consistent quality during the process.

Special wastewater treatment

After passing through the industrial production process, large quantities of wastewater with various degrees of contamination accumulate, most of which require special treatment. This includes cooling water from power plants, water with organic contamination with suspended solids, surfactants or residues from the meat processing industry, with oils and fats from refineries and dairies, heavy metals from the metal processing industry and pesticides from agriculture.

Depending on the industry, mechanical, chemical or biological processes are used in several treatment stages before the treated industrial wastewater can be returned to the application cycle, for example as cooling water or boiler feed water.

Industrial wastewater treatment and disposal is carried out in accordance with the German Wastewater Ordinance. Various residues from the treatment process must be disposed of professionally. Residue analyses are used to ensure that certain limit values are not exceeded.

In industry, there are various approaches for the sustainable use of water as a resource. For example, industrial wastewater can sometimes be used for the environmentally friendly provision of heating energy by means of wastewater heat recovery.

Sturdy valves for pressure and level control

The transportation and storage of industrial water places high demands on the materials used. Mankenberg's self-acting pressure reducing valves, vacuum breakers and bleeding and venting valves are made of high-quality, corrosion-resistant stainless steel using a deep-drawing process. They ensure reliable operation even with aggressive liquids or fluids containing solids. The reliable and easy-to-maintain Mankenberg valves are available with an enormous choice of control ranges and flow rates for industrial water circuits.
