By now you may have already heard of diotomatious earth swimming pool filters and may have a few questions that you need answered. For instance, why are they so efficient at removing the smallest of particulate matter? Also the one big question, what is diatomatious earth and where does it come from?

A Long Long Time Ago

The story of diatomatious earth actually begins eons ago at the dawn of time. Back when the worlds oceans were teaming with one celled microscopic sea creatures called “diatoms”. Diatoms were compised of several types and some types of diatoms contained a microscopic shell much like todays coral.

A White Chalky Substance

This shell, just like the shell on all of todays sea creatures that have them was composed primarily of calcium carbonate, a white, non soluble chalky substance. So as these microscopic diatoms would die off, their shells shells, only the size of a needle tip would sink to the bottom of the ocean.

Many Commercial and Industrial Uses

There they would sit, piling on top of one another until massive deposits were built up. These deposits are now mined today as Diatomatious earth and used in any number of commercial and industrial applications. In fact, the next time you are watching a football game look at he white chalk powder lines on the field and guess what they are made of?

Particles as Small as 5 Microns

Due to their unique biological origins, these tiny sea shells that make up diatomatious earth aren't solid but rather are filled with small passageways that water can flow through. As your pools water flows through these microscopic passageways, particles as small as 5 microns are trapped.

Cheap to Buy

This is what makes diatomatious earth swimming pool filters the best filters available for ridding a pool of extremely small particles. Another thing that makes diatomatious earth a good product to use is that it is very inexpensive.

By now you may already know that swimming pool filters come in three basic types. Those types are sand, DE or “diatomatious earth” and cartridge filters. So which one of the three does the most exacting job of removing the very finest of particles from your pools water?

5 Microns in Diameter

That would definitely be the DE pool filters. This is because DE swimming pool filters are able to trap particles as small as 5 microns in diameter. The next up would be the cartridge filter, that screens out particles of between 10 -15 microns in diameter.

Is it Backwash Time Yet?

Because the DE filter is operated at high pressure, it is imperative that the proper pump be connected to the system. So how do you know when it is time to backwash a DE pool filter to remove the debris that it has accumulated?

Yes! It's Backwash Time

That determination is done by examining the pressure guage that is connected to the filter. When it is registering 6 pounds over normal then that means that the accumulated particles in the filter are begin to clog the system.

Tiny Ancient Microscopic Sea Shells

Each microscopic particle of diatomatious earth is actually the tiny shell of an ancient one celled sea creature called a diatom. They are actually quite porous, which makes them each their own little water filter as the water pases through these incredibly small pores.

More DE Please!

After back flushing a DE filter, the grids inside of the filter itself have to be re coated with diatomatious earth. This is accomplished through a simple process that involves feeding fresh DE, which is essentially a type of very fine powdered chalk back into the filter through the skimmer.

Over the course of the past few decades cartridge style pool filters have been making huge gains in popularity. The reasons are simple. It's all the result of a range of new developments that have served to improve this style of pool filter in several areas. No where is this more obvious then in Hayward pool filters new generation of replacement cartridges.

An Excellent Concept

When cartridge filters were first developed and introduced to the public they were a good product in concept but the actual technology to support the idea was lagging. Older style plastics and manufacturing processes meant that the actual replacement cartridges degraded too quickly and weren't able to remove particles as fine as todays cartridges are now capable of removing.

New Developments

However; all that has changed today and nowhere else is this more apparent than in Hayward pool filters replacement cartridges. Not only are these replacement filters made of a newer and much more superior reinforced polyester plastic but they are also now manufactured to far more exacting specifications.

Number One on the Market

The end result is clearer water, less maintenance and replacement filters that stand up much longer to the harsh environment that they function in. This in turn has led Hayward pool filter replacement cartridges to now be the number one choice today of all replacement filters that are currently on the market.

Energy Efficient

One more benefit of this scientifically engineered and computer aided designed, state if the art replacement filters is greater energy efficiency, as the result of a smoother more even flow-through design that means far less resistance on the pool pump. Remember that the pool pump is where most of the energy that a pool consumes is used and thus should be your primary focus when looking to conserve electricity.

Hayward pool filters come in three basic styles, with those being diatomatious earth, sand and of course cartridge. Cartridge pool filters have been around for decades but in recent years they have been surging in popularity for a number of reasons that may surprise you.

A Basic Concept

The concept of a cartridge filter is quite simple. The swimming pool water enters the system, is directed to the actual filter chamber where it subsequently passes through a plastic filter unit.

The Function of the Filter Unit

First, the larger particles in the water are trapped in the filter unit, which then begins to clog the passageways. As these passageways become tighter by being clogged by these larger particles, they then function to trap the smaller particles that are suspended in the water.

New Advancements in Cartridge Style Hayward Pool Filters

Hayward pool filters are some of the most advanced cartridge type pool filters that are currently available on the market. The development of newer plastics and the refinement of the manufacturing process has led to the emergence of a new family of more durable and effective filters.

Removing Suspended Particles as Small as 10 -15 Microns

Cartridge style Hayward pool filters are have set the  new standard for the entire pool industry. They not only are capable of removing suspended particulate matter as small as ranging between 10 – 15 microns in diameter but they also offer a number of newly developed convenience features that make maintaining your pools filter system a breeze.

Your Pools Unique Water Maintenance Particulars

However,  it is imperative to bear in mind that each pool will have its own maintenance particulars that will enter into the final decision making process of determining just what type of pool filter will suit it best.
