DTP series. Make a grit removal by means of a rotating paddle immersed basin in a conical. An air-lift pump extracts the sand deposited on the bottom, in a simple way and economical.
The sand collection tank, made of reinforced concrete, is circular with a tapered base and central scum box for collecting the sand. The stirring blades, turning at a suitable speed, ensure the sand settles evenly at the base of the tank. Pressurized water is then fed through pipes to clean the sand and remove the floating organic silt which is fed back into the cycle. When it is cleaned, the sand settles again at the bottom and is then removed with the air-lift and put in a scum box.
