Please Note:
When installing Turbidex Systems or Turbidex Media, it is necessary to allow the media to stand in the vessel which has been filled with water for the following times. The Turbidex should not be put into service or backwashed until this priming time has elapsed

16in Vessels and smaller - 30 mins
18-30in Vessels - 60 mins
36-48in Vessels - 120mins
Larger than above - £180mins

Turbidex™ granules consist of a high surface area alumino-silicate mineral that provides exceptional suspended solids filtration. The macro porous nature of TurbidexTM allows for filtration at levels below 5 Microns in particle size.

The irregular surface area and extensive porosity of TurbidexTM makes it the perfect filtration media for any application where solids removal is essential to the process.

Equipment can be smaller or faster flow rates can be achieved for a given size. Particles down to 5 to 10 micron are typically removed. Turbidex must be soaked before use.

The Benefits of Turbidex™

Hyper Filtration Efficiency
With filtration efficiency in the 3 to 5 micron range, Tubidex's enhanced performance results in down stream cost savings for chemicals, filter cartridges, membrane cleaning, membrane life, etc.

Higher Flow Rates
With nominal service flow rates up to 15 gpm/ft2 in pressure filters, TurbidexTM allows significant savings in initial equipment costs when compared to traditional medias. TurbidexTM allows for peak flow rates up to 20 gpm/ft2 Turbidex
