10" x 54" Sediment Filter (Turbidex), Clack WS1 CI Digital Controller, 1.5 m³/hrTurbidex is a unique natural clinoptilolite ore that has many outstanding advantages over common filter sands used for sediment reduction. Turbidex is very angular, rough surfaced and has microporous void spaces as small as 3 microns. This creates a surface area over 100 times greater than sand and can reduce suspended solids down to 5 microns or less (sand filters down to about 40 microns). Turbidex prevents the rapid build up of head loss and
