Carbon filtration is commonly used in drinking water, private water supplies and commercial applications thanks to its ability to adsorb and remove a number of contaminants such as chlorine, VOC’s and even some heavy metals. Our Backwashing Carbon Vessels are the go-to solution for high flow rate carbon filtration where a traditional carbon cartridge will not achieve the required flow rate. The recommended flow rates for these systems are based on de-chlorination, for colour or organics removal the peak flow rate is approximately 20% of that for dichlorination.

Each system is supplied partially assembled, with some of the valve programming already complete, meaning that some assembly will be required on site. Systems come as standard with a Pentair Clack WS1 control valve, with 1” inlet and outlet.

How Often Do I Need To Replace The Carbon In These Backwashing Carbon Filters?
It is recommended to replace the carbon media annually for hygiene purposes. If you start to notice chlorine breakthrough or the carbon media feels slimy, it should be replaced sooner.
