The Evoqua HOT recirculating system effectively heat sanitizes carbon towers while reducing water and energy by up to 75% of conventional designs. The system improves on conventional systems by recirculating the backwash wtater while sanitizing the carbon media, providing advanced bacteria control and reduce water and energy requirements. Bacteria in production water and biofouling of water treatment systems can create operational challenges for beverage manufacturers. To meet these challenges, Evoqua offers the Heat Optimized Technology “HOT” Series Systems.
The HOT process provides thorough sanitization of new or existing carbon towers, reduces backwash water by up to 75%, and adds process control. With a small footprint, the fully skidded, stainless steel systems are a small addition, but offer many benefits to existing carbon tower installations: Field proven to provide more effective microbial kill than conventional steaming processes, Up to 75% reduction in backwash water to conserve precious resources, The heating system can sanitize the loop distribution piping and polishing equipment for improved operations. Bacteria is kept under better control because of uniform heating of the carbon bed in the expanded state and reduced potential for cold spots using hot water, the HOT Series System eliminates the potential for bed contamination that can exist from utilizing plant steam.
The HOT Series System is a skid-mounted system. The skid structure and all process piping are stainless steel. The dynamic components consist of valves, filter, heat exchanger, pump, and sample ports. Mechanical connections are a combination of tri-clamp, tube flanges, and threads with an option for all tri-clamp connections. The standard HOT system is designed to service anywhere from one to three carbon towers having equal backwash flow rates.
The HOT Series System utilizes a patented process for sanitizing carbon towers to control bacterial growth and organic fouling. By combining the carbon tower’s backwash and sanitization steps with a recirculation process in one cohesive step, this technology greatly increases the effectiveness of the sanitization, while reducing water consumption, and both simplifying and speeding up the process. A HOT Series System can be provided independently, with or without an optional chilling exchanger, or as a complete system including carbon towers and ancillary equipment.
