The reduction of microorganisms and TOC (total organic carbon) is necessary pretreatment to prevent contamination and biological fouling. WPT offers two types of process to reduce these constituents resulting in fewer cleaning cycles and longer membrane life.
UV (Ultraviolet) Disinfection and TOC Reduction
WPT provides skid mounted UV treatment systems to disinfect and to reduce organics in water purification systems. Selection of the type of UV lamp is important depending upon whether simple disinfection or TOC reduction is required. Water is passed through chambers containing sheathed UV lamps. Each lamp emits radiation, which results in photons being adsorbed by the microorganisms and organic compounds. The microorganisms are prevented from reproduction by photons, which penetrate the cell membranes and disrupt the genetic material. The photons also reduce TOC by excitation of the chemical’s bonds resulting in the breakdown of organics contributing to TOC
Ozonation
Ozone is generated on-site by an ozone generator. Through electrical charge, oxygen molecules from an air or industrial oxygen supply are converted from O2 to O3 (ozone). Ozone is a highly oxidative gas, which breaks down the cell membranes of bacteria and viruses, thus destroying them.
