Groundwater, seawater, lake, reservoir water, pond water, cooling water circulation, frozen water, high and low voltage gush to drench water, squirt water, seal water, bearing seal water, oil well note water, etc.

  • Automatic and continuous filtration without interruption the flow, reduce down time and operation cost.
  • Low velocity filtration design, pressure drop low and delay the filter cake built up, fine filtration, back-flushing quantity of water low and save cost.
  • Wedge wire screen, smooth surface, back-flushing effect good, compact structure, life time long.
  • Back-flushing elements step by step, effect good and less back wash water consumption.
  • Single vessel can handle large capacity and save installation and space cost.
  • No need many control valves, inter connecting pipes and fittings, reliable and operating cost is very low.
  • Fully automatic control system and easy operation and linked with DCS control system.
