The Sludge Watch 715 provides a simple, low cost method of spot checking the sludge blanket level in a wide variety of settlement tanks. The cable reel design removes the need for any additional carrying bag.

The Sludge Watch 715 uses a range of infrared sensors to make the sludge interface detection. Infrared attenuation has been selected as it is ideally suited to detecting the sludge present in the interface zone. This tends to be considerably ‘thinner‘ than the sludge that is present at the bottom of a settlement tank.

This method of sludge blanket detection offers major improvement over traditional Sludge Judge type systems in terms of both repeatability and importantly health and safety – no more manhandling 4 metre tubes full of contaminated wastewater.
