SAND FILTERS
2Pages

Media Filters Minimal head loss due to nozzles or collector arms. Sand filters can be used in manual, automatic or semi-automatic stations. From 350 mm up to 1.400 mm of diameter. TECHNICAL DATA SYSTEM The filtration through sand is produced by physical retaining the dirt into the gaps formed between the granules laid throughout the whole mantle. This is an in-depth filtration, characteristic that gives sand filtration to be most efficient system of all. CONSTRUCTION MATERIALS Body: carbon steel. Manifolds: carbon steel or polyethylene. Joints: synthetic rubber nitrile 60º Shore. Screws: zinc-plated weather resistant. Closing cover inlet and outlet water: 15 mm melting. Collector arms and nozzles: polypropylene. STEEL SURFACE TREATMENT The steel elements are treated internally and externally and an impregnation of NANOTECHNOLOGY. After that, the elements are painted by electrostatic spraying powder paint, epoxy polyester. FILTERING ELEMENT Volcanic sand (standard) and siliceous sand. CLEANING Cleaning takes place by reverse filtration, by opening the drain valve to the exterior dislodging through it all the dirt. The systems can be automatic if a GLOBO valve is used. The cleaning process is guarantee thanks to collector arms or nozzles which are along the media filter basis. PRESSURES Max. pressure: 8 kg/cm² Min. cleaning pressure: 2,5 kg/cm² Nozzle Testing pressure: 16 kg/cm² Volcanic sand (standard) Siliceous sand Filtration using low media filters, either through nozzles or collector arms, is the most exhaustive of all filter equipment. It is particularly indicated to lower the concentration of suspended solids and water turbidity.
