Raw Water Treatment

Industrial raw water treatment is the treatment of incoming water and used to optimize most water-based industrial processes, such as heating, cooling, processing, cleaning and rinsing. The ultimate goal is to reduce operating costs and risks.

Poor raw water treatment can cause serious damage to the process and the final product. Surfaces of pipes and vessels can be affected by corrosion and steam boilers can scale up or corrode.

We will support you to deal with these numerous raw water treatment challenges.


Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water has been the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization.


Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using lime softening or ion-exchange resins.

Multimedia filtration

Pressure vessels with sand or other loose media, at different granulometric measure, are widely used in industrial filtration applications. During the cleaning cycle, called “backwash”, the bed is lifted (or “fluidized”) to loosen the filter media and release trapped dirt which is removed in the backwash flow.

Granular active filtration

Granulated Activated Carbon (GAC) is a common filter material used in water filtration systems. It’s a proven way to remove certain organic chemicals from water. GAC filters are also effective at removing contaminants that give an objectionable odor or taste to drinking water, like hydrogen sulfide or chlorine.


Chemical oxidation generates precipitation of Fe and Mn Hydroxide. A final Sand Filtration, usually, is enough to remove totally Fe and Mn.

Clorination and declorination

Water chlorination is the process of adding chlorine (Cl2) or hypochlorite to water. This method is used to kill certain bacteria and other microbes in tap water as chlorine is highly toxic. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, typhoid etc.


Water disinfection means the removal, deactivation or killing of pathogenic microorganisms. Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. When microorganisms are not removed from drinking water, drinking water usage will cause people to fall ill. Sterilization is a process related to disinfection. However, during the sterilization process all present microorganisms are killed, both harmful and harmless microorganisms. Disinfection is realised also by Ultra Violet Filters.

Reverse Osmosis

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
