Water Treatment Solutions Shown at IFAT

Severn Trent Services (USA) will be attending IFAT ENTSORGA. The company will be demonstrating its innovative solutions for water and wastewater treatment at stand A1.105.

Pressure on the world’s water resources driven by climate change and population growth has created increased global demand for desalination and water reclamation / reuse technologies. Visitors to the Severn Trent Services stand can obtain information about the company’s proven technologies designed to address world water shortages. The company has been providing water desalination technologies for more than 25 years and treatment solutions for reuse applications for more than 40 years.

Tertiary Treatment Systems
The TETRA® DeepBed™ filtration system is a down flow sand filter for the filtration of effluent from municipal wastewater treatment plants. The technology offers process flexibility and high efficiency backwash for the removal of suspended solids and other insoluble contaminants. For nitrate-nitrogen and suspended solids removal, the process is easily upgraded to the TETRA® Denite® system, a fixed-film biological denitrification process. The Denite system integrates well with other plant treatment processes to provide superior total nitrogen and phosphorous removal.

Electrochlorination technology
Severn Trent Services has developed a cost-effective system for the on-site production of sodium hypochlorite for use in swimming pools, cooling towers and food and drink applications – the ClorTec SCT mini on-site sodium hypochlorite generating system. This compact, innovative new product offers a safe and reliable alternative to the transportation of hazardous chemicals and is easy to maintain.

Microwave UV disinfection
The MicroDynamics system uses microwave energy to energize the bulbs and generate consistent-strength UV disinfection. The system offers extended bulb life and reliability, operating cost savings and health and safety benefits for employees on site due to its unique design. The bulb replacement and maintenance costs of MicroDynamics systems can be as little as half of competing UV technologies, primarily driven by the unique microwave-powered electrodeless lamps. Each system comes with a three-year bulb life warranty.
Underdrain filters for drinking water applications.

Underdrain filters for drinking water applications
The TETRA® LP Block,™ a dual parallel lateral underdrain filter floor for RGF and GAC filters, is extremely popular with plant owners for their low headloss, lightweight construction and easy installation. The system provides excellent distribution of both backwash air and water to offer more efficient bed cleaning and lower operating costs. Severn Trent Services has been awarded several contracts to supply TETRA LP Blocks for pre-treatment at desalination plants throughout Europe including the recently completed Fouka SWRO plant at Tipaza, Algeria, in conjunction with ACCIONA AGUA.
