Activated Carbon Filters Activated carbon pressure filter manufacture to DIN standards and rated at 10 bar pressure. The equipment is fitted with 2 x manholes, one on top of the filter for the addition of media, and the second just above the nozzle distribution plate. The filter is a heavy duty high performance filter that can be easily maintained, very few high pressure activated carbon filters can actually be maintained by the end user, and because our filters are quality products they carry a 5 year warranty. The filter media is a consumable.
 		  
stainless steel Horizontal stainless steel 316 pressure filters with a stainless steel  wedge wire screen distribution plate. Surface area 3 square meters bed depth approximately 0.6 square meters.

The filter is designed for heavy duty applications in waste water and is manufactured by Dryden Aqua.  We can also manufacture vertical filters in 316 grade or Incaloy stainless steel up to 1 m in diameter. Larger filters will take a bit longer.
