Severn Trent Services, a leading global supplier of water and wastewater solutions, will be exhibiting at Singapore International Water Week from 1 – 5 July 2012. The company will be showcasing its innovative technologies for water and wastewater treatment on stand J28.
Tertiary treatment systems
Systems featuring Severn Trent Services’ tertiary treatment technologies have been installed at more than 300 sites worldwide. 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. TETRA Denite and TETRA DeepBed filters represent more than 10 percent of the world’s capacity for wastewater reuse systems including more than 40 percent of all installations in Florida, USA.
Electrochlorination technology
Severn Trent Services is a leading supplier of electrochlorination technology. Since 1988 the company has installed more than 3,500 ClorTec® on-site sodium hypochlorite generating systems worldwide. Severn Trent Services also 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 product offers a safe and reliable alternative to the transportation of hazardous chemicals and is easy to maintain.
Gas Feed Disinfection
Severn Trent Services has more than 40 years’ experience providing gas disinfection systems. The company offers a wide range of Capital Controls® gas feed systems and accessories capable of feeding various gaseous solutions including chlorine, sulfur dioxide, ammonia and carbon dioxide.
The Capital Controls® 70CV3000 Chloromatic™ Intelligent Gas Flow Control Valve is designed to control chemical feed in water or wastewater disinfection applications. The design offers variable capacities up to 60kg/h, ease of installation, elimination of requirements for continuous operator monitoring and reduced gas consumption.
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. The GroutGrip™ and new Anchor-Rite® design features eliminate the uncertainty of grout installation and ensure increased adhesion to the filter floor.
