Cartridge Filter Media: Pool cartridge filters clean down to the 10-15 micron range. Replacement and maintenance are easier compared to a sand filter. There is no need for backwashing, cartridge filters are easily removed and cleaned or just replaced. These filters reduce energy cost by the reduced pressure required to operate.
Sand filters are used to remove suspended solids from water and wastewater. Because they have one layer of filter media, sand filters remove only relatively large solids (normally in the range of 40 micron and larger). The effective size of each granule of sand typically varies from 0.35mm – 1.2mm. Larger granules yield coarser filtration.
Size of Pool Pad Depending on your equipment, the size of the equipment will vary. Our inground pool kits include a Hayward sand filter system, and two Jandy valves. The smallest pad size I would recommend would be 4'x4'. A 4'x6' is a nice size to work around. If you plan to add a heat pump or gas heater, you'll need another 4'x4' pad, or one 4 ...
The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological filtration and depends primarily on ...

May 30, 2016· Hello and welcome back to our pool equipment selection series. We've already walked you through the process of sizing up the pump. The next step will be to select the type of filter that can handle the size of the pool and the pump.There are three filter types common on residential pools, and they are Sand, Cartridge, and DE.
Sand Filters. For sand filters on inground pools, I like to use a 30" tank diameter, which has a 4.9 sq. ft. filter surface area and holds 600 lbs of sand. For small pools (under 20,000 gallons), I might advise the next size down (24" tank) if the budget is tight. But never go smaller than a this for an inground pool. Cartridge Filters
Users can maintain flow rate by cleaning the filter through agitating the top level of sand, or by pre-treating turbid water before filtration. Lab Effectiveness, Field Effectiveness, and Health Impact. Slow sand filter lab effectiveness studies with a mature biolayer have shown 99.98% protozoan, 90-99% bacterial, and variable viral reduction.
Filter Sizing and Flow Rates. There are three common pool filter types – sand, cartridge and Diatomaceous Earth (D.E.). All three of these pool filter types will keep your pool and spa clean, but you should consider the needs of your specific application, your other equipment and plumbing size before making a selection.
