Plastic Filter Nozzle & Under-Drain Collection Systems

Plastic Filter Nozzles
Guddi Plastcon can offer expert advise in designing, sizing & material selecting of filter nozzles for any particular application. Filter nozzles are designed to be used in all filter & drainage system & can be active in sand, anthracite, activated carbon, concrete & ion exchange resin treatment. Filter Nozzles can be produced in a various combination of stem lengths, stem diameter, air holes, air slots & strainer slotted widths due to a flexible system of moulds.

Under Drain Collection Systems
Proper functioning of the nozzle assembly is of vital importance to the filtration & backwashing process of any gravity filters. Guddi make nozzle slots are sized to prevent the smallest particles of sand from entering the under drain but not so small as to give excessive head loss through the slots. The nozzles are set at an exactly uniform level & therefore evenly distributes air while air scour.

Plastic Filter Nozzles
Material for production of Filter Nozzle is carefully chosen & regularly tested. Nozzles are normally produced in PP (polypropylene) but can also be produced in PVDF, PP glass filled,PP-LTHA, ABS,and in Stainless Steel grades SS 304, SS316L, etc. From above wide range of material we select those best suited to each plants operating condition, with ideal mechanical strength & chemical & thermal resistance, in order to guarantee maximum operation & durability.
