Microfiltration (“MF”) is a proven filtration process based on microporous membranes. Separation is achieved based on a process where a liquid is forced through a semipermeable membrane through the application of pressure. Suspended solids and solutes of high molecular weight are retained, while water ...

Nanofiltration (“NF”) is a relatively new membrane filtration process. Similar to Ultrafiltration, separation is achieved based on “size exclusion”. A liquid is forced through a semipermeable membrane with pores in the range of 1 -10 nanometers through the application of pressure. A wide range of contaminants is retained, while water and low molecular weight solutes pass ...

Ultraviolet (UV) water disinfection instantly kills bacteria, parasites and viruses by passing the water past an UV light source, which damages the DNA of these organisms. UV disinfection should be installed as close as possible to the point of end use, as the effect of a UV disinfection is only temporary – the water may become re-contaminated when stored in tanks or even in pipe work ...

Ultrafiltration (“UF”) is a proven filtration process based on microporous membranes. Separation is achieved based on a process where a liquid is forced through a semipermeable membrane through the application of pressure. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane in the permeate or ...

Water disinfection is critical to ensure the safety of any potable water supply. Chlorination is a highly effective way to disinfect potable water, and can be dosed into the water as a chlorine gas (Cl2) or as a liquid (Sodium Hypochlorite). The major advantage of chlorine is its residual disinfection effect; it ensures disinfection right up to the point of end use. When water is stored for ...
