Manufactured by:Herco Wassertechnik GmbH based inFreiberg, GERMANY
Electrodeionisation (abbreviated to “EDI”) or electrodialysis is a process for the continuous desalination of permeate from a reverse osmosis unit. An EDI module consists of several chambers that are separated from one another by ion-selective membranes. The chambers are filled with ion exchange resin and arranged between two DC ...
Manufactured by:Herco Wassertechnik GmbH based inFreiberg, GERMANY
Automatic hardness monitoring for continuous control of the soft water downstream of water softening units. Automatic switch off of a downstream reverse osmosis unit in the event of hardness breakthrough. For their operation neither water nor chemicals are consumed. ...

If municipal utilities do not deliver a constant volumetric flow/mains pressure to the intake of a unit, then a pressure booster unit can be integrated into the system in order to ensure constant pressure. This is required before or after the softener / reverse osmosis. The unit maintains the selected operating pressure at a constant rate by adjusting the frequency, even when the required flow ...

Special inlet filter with 5 µm-filter cartridge and 2 pressure gauges, High pressure pump, low-noise, multi-stage centrifugal type, Low energy wound modules with energy saving PA/PS composite membranes in GRP vessels Valves and instruments including feed water sampling valve, solenoid inlet valve, feed ...
Manufactured by:Herco Wassertechnik GmbH based inFreiberg, GERMANY
Filtration is an essential process in water treatment. It is used to remove contaminants such as particles, suspended matter, bacteria, organic substances and chemicals from the water. This primarily mechanical process, which can also have physical and chemical filtration effects, focusses on the separation or purification of suspensions or solutions. The substances in the water fall into two ...

If pure water vaporises or evaporates in water circuits it leads to a thickening or salting of the water contents. Blowdown units automatically control the salt content in the circulating water and protect cooling water circuits from water-related deposits and corrosion. The blowdown units and bypass measuring distances are for monitoring and limiting thickening in open coolant circuits and air ...

Herco’s EKP cleaning and descaling pumps have a multi-way control valve to enable stepless control of the pressure and delivery rate, as well as for controlling the flow and return flow. All of the components that come into contact with the media are made of acid-resistant and alkali-resistant materials. The pumps can be operated with cold and hot water up to 50 ...
Manufactured by:Herco Wassertechnik GmbH based inFreiberg, GERMANY
Water demineralisation using a mixed-bed refers to a water treatment process used to produce high-purity water with extremely low levels of dissolved solids and ions. To remove dissolved (dissociated) ions, special cation and anion exchange resins are used in water treatment. They take in the ions that have dissolved in the water and in their place give out an equivalent amount of different ions ...

Stainless steel main frame corrosion protected housing the instruments and controls.2 Special inlet filters with 100 µm-/5 µm-filter cartridge, Pump set consisting in high pressure piston-pump with flexible pressure-hose and overpressure-assembly for fail safety. Seawater-spirally wound module with energy-efficient PA/PS composite membrane in GRP vessel with liner. Valves for ...
Manufactured by:Herco Wassertechnik GmbH based inFreiberg, GERMANY
In the softening unit, calcium ions (Ca2+) and magnesium ions (Mg2+), which are hardeners present in natural water, are exchanged for sodium ions (Na+). Ion exchangers are used for this process. The ion exchangers consist of spherical synthetic pellets based on polystyrene. They are also commonly referred to as exchange resins. However, the absorption capacity of the ion exchanger for the ...
