General Characteristics Their anti corrosive protection includes surface treatment using phosphoric acids followed by electrostatic polyesteric paint, while other available paint and material options are also available pending request. The product is supplied with multiple couplings and flanges options availability (DIN,ASA, etc) conforminng to all required international standars. The maximum operating pressure is 8 bars (116 psi). They are available in other specifications, such as self cleaning version. DROP Filtration Systems Irrigation Equipment SAND MEDIA FILTERS X series The X series filters are used mainly in applications where the contaminated water has increased organic contaminance (algae, seaweeds etc) or even inorganic contaminants Due to their three-dimensional nature they have the ability to withhold large quantities of particles. The filtration media which accomplishes the filtering is silica sand, in different available grain size depending on the required filtration needs. The sand media filters are cleaned by means of a backwash procedure. The water flow direction is reversed, the sand volume increases and the withholded particles are drained outwards. The double chambered sand media filters have the «same characteristics with those of the single chamber, the only difference is that they are effectively two filters in one array and hence they have the capability to perform self cleaning without interuptions to the clean waterflow rate.

Media data - Silica sand selection matrix ilicasand designation no Two factors describe the attributes of the filtration media used in sand media filters: The Coefficient of Uniformity is an indicator which expresses the variance of the grain size particles in a sample. For better filtration control the silica sand must be as uniform in size as possible. Large variations of silica sand grain sizes will result...

Product Specification Sheet: X series DROP Filtration Systems Irrigation Equipment For better filtration results and to accomodate demand for filtration of greater water flow rates, sand media filter combinations are assembled in filtration systems. These are available either in manual or automatic cleaning process versions. The use of sand media filter systems enables the filtration of vastly greater water flow rates than a single filter station, as well as providing the advantage of continous watrer flow rate during the cleaning process (irrigation, waiter supply). The optimum system choice...
