After the water flotation the clear water passes through the sand bed filter to be sure all particles are removed. Depending on the size of the purifying system one or more units of 1 micron side deep bed sand / glass filter unit type SMDD, using 2.5 bar pressure will be used, including all connections, back wash system and piping.


The nozzle plate system also allows the inlet of pressurized air directly into the bottom of the filter media. Uniform inlet of air and water through the nozzle plate provides vigorous agitation and filter media bed expansion required for an effective air/water leading to reduce backwashing times and reduction of volumes of water. Save up to 25% of backwash water!
