- About Us
The Food and Beverage market includes diverse industries, such as bottled water, carbonated & non-carbonated beverages and dairy plants. Ultraviolet (UV) technology has been successfully used in these industries for control of pathogen microorganisms.
Aquafine UV systems are also used to disinfect any product water used as an ingredient in beverage products. Bottled water and product water for concentrates, soft drinks, tea and beer are commonly disinfected with Aquafine 254nm UV systems.
Heat treatment-pasteurization techniques are efficient in handling low UV transmittance (UVT) and some degree of suspended solids (SS) and total dissolved solids (TDS) and are preferred by many product producers. However, pasteurization is expensive and UV can be efficient as the pasteurization and energy costs continue to rise. UV is a non-chemical process and doesn’t change any physical characteristic of the fluid and concerns of chemical handling and cost of removal of chlorine from the water stream are eliminated.
Most importantly, UV treatment does not promote the generation of disinfection by-products, such as Trihalomethanes (THM), which regulatory agencies have classified as carcinogenic at certain levels in drinking water.
