High bed sand filters
High bed sand filters
Description:
High bed automatic sand filters are specially designed for water treatment.
Features:
- Filtering element: From one or several filtering layers. These ones combine more than a filtering material from different granulometries and densities from larger to smaller granulometry and from smaller to larger density.
Filtering materials: volcanic sand, anthracite, silica sand, active coal…
- Water collection system: Using arms collector evenly distributed in the filtering bed, or with a false mushrooms bottom.
- Equipment: High bed automatic sand equipments are supplied with valves, joints, screws, suction pads, pressure gauges, an automatic cleaning timer, a differential pressure switch and connection collectors.
- Materials: Filter body and collectors made of carbon steel with a treatment of sandblasting- phosphating, inner/outer electrostatic paint coats in epoxi-polyester, later polymerized in a high-temperature oven. They can be manufactured from stainless.
- Modularity: Its modular design allows an easy enlargement and adaptation to any kind of spaces. Regarding these equipments, the number of filters, the diameter of collectors and the size and number of valves depend on flow, water quality and filtration grade required.
- Pressure features: Maximum work pressure: 10 kg/cm2. Equipments with higher pressure requirements can be also supplied to order.
- Adaptations: Special solutions can be found for use as feeding purposes. and possibility of cleaning using external water or air.
Operation/TechnologyApplicationsModels
- Filtering process: The water flows into the filter from the upper part; the filtration process is produced by the retention of dirt particles and the effect of its adherence through the sand bed and in all its path, finally passing through diffusers on the lower parts, that avoid sand evacuation.
- Self-cleaning process: By discharge, due to an increase in the amount of dirt in the filter. The cleaning process is made by the inversion of the water flow, upside down, from bottom to top, with previously filtered water.
Unclean water with dirt particles from counterwashing goes out by the drain valve.
