Almost sand filters employ #20 sand or mesh crystal silica #20, but they may as well apply drinking glass or zeolite. The sand filter housing is typically fabricated from stainless steel, fiberglass, or plastic and is durable plenty to withstand the high force per unit area required to run the filtration system.

How Does a Sand Filter Work?

Sand filters function by moving the water from the acme of the tank through the sand to the bottom of the tank via loftier pressure level. Every bit the water trickles downwardly, the sharp edges of the sand grains catch particles like dirt, debris, and torso waste materials. Smaller and smaller particles are removed from the water as it cycles through until the sand becomes too dumbo and needs to be cleaned AKA backwashed.

Backwashing Your Sand Filter

To cleanse the sand, the sand filter volition need to exist backwashed (manual or automatic). Backwashing your sand filter reverses the flow of water through the sand, starting from the laterals at the bottom and working its way upwards to top, collecting debris and particles every bit it goes.

Y'all can recollect of it like a fountain. The h2o can enter a fountain from whatsoever direction, only no thing what, the water needs to trickle downwardly from the elevation tier.

Once at the tiptop of the sand filter tank, the pool water goes through a benefactor to ensure it'south evenly spread over the sand bed.

The pool water then washes through the sand leaving behind impurities before arriving at the laterals located at the bottom of the tank. The lateral openings are just large enough to permit the water pass through but also small for sand to squeeze by and end up in the pool.

During the backwash process, the water comes out of the laterals  at the lesser and travels up the sand and through the distributors at the top to waste material.

Sand Filter vs. D.E. Filter

A D.E. filter consists of a set of grids coated with a white powder made upwards of crushed seashells and fossilized diatoms (AKA diatomaceous earth). These filters can catch dirt and debris 5 microns and bigger.

Crushed seashells and fossils might sound like a weird way to make clean your pool, but a D.East. filter looks like whatsoever other pool filter and functions similarly. The main deviation is in how information technology works and how it is maintained.

The diatomaceous earth is layered over a mesh to form a fine screen. As the water passes through the system, the D.Eastward. traps particles and debris and keeps it from going back into the pool. Like a sand filter, D.E. filters need to exist backwashed to clear out stuck debris and particles before resuming regular filtration, and backwashing may need to be repeated several times. Manual cleaning of the grids is required about every ninety days.

Warning: D.E. pulverization tin be chancy to handle. Delight utilize advisable face and eyewear while servicing your filtration organisation.

The D.E. powder also needs to exist continually added to the arrangement to keep the filtration procedure going, whereas sand tin go years without being replaced. On the flip side, they produce clearer water and trap much smaller particles than sand filters.

Sand Filter or Cartridge Filter: Which Is Better?

A cartridge filter uses pleated fabric wrapped around a cylindrical cadre to filter pool water and catch debris every bit it goes through the system. Cartridge filters are used on pools and spas, are compact in size, and don't need to exist backwashed. They are also piece of cake to maintain as they only demand to exist rinsed with a hose about every four to vi weeks, depending on the size. The filter might need to be soaked in a filter cleaning solution on occasion, peculiarly if you've been having problem with algae.

In our personal opinion, cartridge filters are more than effective at removing impurities and keeping the puddle water clear than sand filters. Cartridge filters are also easy to maintain, catch smaller particles than sand filters, reduce the load on the pool pump, and don't require any backwashing. As a bonus, yous won't need to handle potentially dangerous materials (sand, silica, zeolite, etc.).
