Derwent Water Systems supply an extensive and comprehensive range of Filtration Plant. Click on a link below to view the range.
Raw water supplies i.e. river waters, dam waters, borehole waters, can be contaminated with high levels of suspended solids – typically:
- process foulants
The increasing need to save money on the cost of water and to better use this valuable resource, water re-use and re-cycling on industrial sites is becoming more important.
Filters minimise the build-up of suspended solids in cooling tower systems, under which harmful and troublesome bacteria grow, keeping systems clean and enhancing cooling efficiency.
Derwent Water Services has filtration plant available to solve all of the above suspended solids problems with filter plants having the following filtration media:
- Graded sand/gravel
- Activated carbon
- Iron/Manganese removal media
The Derwent range of standard filter vessels are conservatively sized to give flow loadings per square metre of filter bed which are well within design criteria and which therefore give improved and reliable filtration.
The units are available with either:
- Well-proven 5-cycle corrosion-resistant muitiport valve
- Manifold with individual control valves
The units can be in simplex, duplex or multiple combinations.
Triplex combinations allow two filters to provide backwash water for the third filter, which often eliminates for large storage of clean water for backwash.
The filtration process is controlled from a central control panel complete with warning lights and an engraved mimic on which lamps show the service state of all items. The panel houses circuit breakers, motor starters and level switches and PLC.
