FILTERS IN PE MATERIAL OR GALVANIZED WITH NET FILTER CARTRIDGE (STEEL)
These filters are suitable for systems with micro jet irrigation or sprinklers. They are suitable to hold small amounts of impurities in the water, otherwise are used as safety filters on secondary pipelines to catch any debris or waste.
FILTERS WITH STEEL GRIT
These filters are designed to remove algae or solid substances. The grit filter is used to filter surface water (from dams, canals, rivers or reservoirs) as well as very dirty wastewater. This is the type of filter able to retain and remove organic substances, mucilage, algae and solids stuck in the water.
Sand filters are proper to eliminate small impurities. These filters are similar to grit filters for construction, however, inside it holds fine sand (Ø 1/2 mm), which allows to filter very fine sand (and micro impurities) lying on wells or similar spots.
This type of filters is suggested to take sand out. Hydrocyclone is a device simple and effective for separation of heavy particles that may be present in the water. This filter can be used with excellent results to separate sand stuck in well’s water or stream and is located in the middle of pump and the filter safety net.
Disk filters are the best systems supplied in this industry so far. Filtration process: the water gets through the inlet manifold from the bottom of the filter body. As the water enters the filter, a powerful cyclonic motion is pushed by the turbine blades which are located at the base. The water, swirling, drags some of the particles towards the inner wall of the filter up to the top of the bell, where they stick until the next wash cycle. The water goes through disk pack from outside towards the inside by passing through the grooves printed on the surface of the disks which retains the suspended materials. The disk pack is kept compressed by the piston at the top spot. Clean water made out of filtering comes out from the exit located at the bottom center.
NET FILTERS WITH AUTOMATIC BACKWASHING
Automatic net filters are suggested for all types of impurities. Equipped with pre-filter and mesh filter with automatic backwash guarantees high amount of filtering without losing any pressure in the irrigation system. It works exclusively with water’s flow (energy is not necessary). There are various sizes of filters according to the required flows.
