Pool Filters For Above Ground Pools

Introduction

Pool Filters For Above Ground Pools, The purpose of filters both in-ground and above-ground to keep a pool clear of dirt and debris. After the water is pumped to the filter, it is filtered with sand, cartridges, or DE media, and finally, it is returned to the pool as clean water.

It will help to circulate all of the water in your above-ground pool within eight hours. Filters help to eliminate bacteria algae and other microscopic particles making your pool cleaner and safer to swim in. Improve the effectiveness of chlorine in killing bacteria, fostering a healthy swimming pool environment. Why are above-ground pools better than ground pools? It is easier to maintain many above-ground pools because of their size and construction. As a result, they may require fewer chemicals and require less costly maintenance.

What are the important types of pool filters?

Here we discuss 3 types of filters: Diatomaceous Earth Filters (also called D.E filters), Cartridge Filters, and Sand Filters. The size of the pool is one of the most important factors to consider when choosing a filter. Filters of all types need to be the right size. For your pool, you must have the right size filter.

  1. Diatomaceous Earth Filter( D.E Filter)

D.E. filters use ( Diatomaceous earth particle) powder made from crushed fossils of single-celled algae to filter your pool water. Diatoms contain high amounts of silica as silica is a major component of sand. The powder that you add to the skimmer coats captures unwanted contaminants and allows water in. D.E. filters have the strongest and superior water filtration capabilities down to 5 micrometers, since they pick up such small particles they will lose pressure faster than other types of filters. DE filters provide the highest water quality, but at a cost, as they are the even most expensive and highly maintenance-intensive pool filters.

For instance, maintenance is required when the tank’s pressure gauge indicates high pressure, just like sand filters. As it is a little when DE powder is added to the filter when backwashed. Always wear a mask when handling diatom powder. It may be toxic and irritating when inhaled in large amounts, also it may also harm your lungs. If your city may have D.E. disposal forbiddances, such as no backwashing into streams or wastewater collection systems. This problem will be sorted out when contacting your municipal regulation authority regarding local D.E. disposal regulations.

Advantages of DE filters:

  • The most effective filtration system suitable for above-ground pool
  • For every few months backwashing.
  • Filter grids last longer if properly maintained and cared for.

Disadvantages of DE filters:

  • Diatom powder is used making it the most expensive
  • High maintenance is required
  • DE powder is toxic and irritating to the lungs that’s why should not be inhaled
  • Potential disposal restrictions because of toxicity when backwashed.

2. Cartridge Filter for pools:

Cartridge filters consist of pleated cartridges, a piece tank lid, and a bottom that captures debris when pool water flows through a tank. This filter is similar to the air filter we will mostly find in cars’ filtration systems. The cartridge pleats trap contaminants as small as 10 microns and clean filtered water gets back to the pool. Cartridge filters trap debris up to 10-15 micrometers range. Filtration efficiency is higher than sand filters. However, they are considered more expensive than sand filters and occupy a different, yet simple and unique maintenance process.

Pressure in the tank will increase when the cartridges are dirty and full of debris. When the tank’s pressure gauge reaches high pressure, it is time for maintenance and time to deep clean the cartridge. When you clean your cartridge filter, first of all, take the cartridge out of the tank spray it, and hose it down thoroughly with your garden hose and remove dirt. When the cartridges are particularly dirty, you may need to gently brush them to loosen the debris. Sometimes brushing weakens the filter media, so the more often you do it, the more often the cartridges inside the filter will last about 1 to 3 years before needing to be replaced

Advantages of cartridge filters

  • Efficient filtration capabilities are easily manageable
  • Loss of water is Less due to no backwashing
  • Easy to clean, handle, and replace filters, as no use of any harmful chemical.
  • Less maintenance is required.

Disadvantages of cartridge filters:

  • Expensive in a sense higher initial and maintenance cost
  • Deep cleaning is required after almost 6 months.
  • Brushing weakens the filter media. There is a need to replace cartridges every 2-3 years.

3. Sand pool filters

Sand filters involve a hollow tank on a stand full of sand that traps contaminants as water percolates through. While to the naked eye, it appears smooth, when viewed under a microscope each grain of sand has prickly, rough edges that help to grab contaminants. When the water is pushed through sand, dirt and debris remain trapped in the sand, clean clear water then travels to the bottom of the tank to clarify your pool water.

Sand filters trap and remove contaminants as per 20 microns. However, sand filters are the least effective as compared to other pool filters, like cartridge and DE filters. D.E. Filter can trap even smaller particles.

Over time, as the particles trapped in the sand restrict the water following back to the pool, build up and render the filter less effective. As particles are trapped they prevent proper water flow and raise the pressure gauge in the tank.

A pressure gauge on the side of the filter is an alert sign that there is a need for pressure changes and indicates when it’s time to perform a backwash. For sand filters, maintenance is very simple and easy. All you need to do is backwash, it will send out dirty water through another port, the filter which means running the water in the reverse direction to flush out debris, that port is mostly labeled as “waste”.Operating pressure will depend upon size it can vary depending on pump size . When more economical backwashing is required, replace the sand, but this change is only necessary every 5-7 years.

Keep in mind that most tanks will start between 10_15 Psi when frequently backwash your filter, you can disrupt your pool’s chemistry and pool water levels. When this level increases by 10 pounds it’s time to rebalance the chemicals, backwash the above-ground pool filter, and refill your pool.

Advantages of sand filters

  • Least expensive as compared to cartridge and D.E filter
  • Low maintenance is required
  • With no complications, straightforward operation.
  • With no size issue available in any pool size.

Disadvantages of sand filters

  • The least effective filtration of sand particles is too small.
  • Little backwashing may be needed but great water loss.
  • Continuing backwashing may alter the pool’s chemical balance.

What is the difference between ground and above-pool filters

Above-ground pools are usually smaller than ground pools, and their filters are designed to handle a smaller version’s flow rate and smaller volumes of water.

Moreover, ground pool filters are situated near your home or as possible as close to the electrical panel. Above-ground pool filters are always placed beneath the water level next to the pool. A ground pool filter is more complicated as it requires more gravity for their filter system, more feet of plumbing, high suction lines, and more skimmers, In contrast to above ground system.

Which type of pool filter is best?

Large filters require less maintenance as compared to smaller filters because they acquire much faster speed. While choosing filters we consider overall performance, capability, long-lasting operations, cost preference, ease of maintenance, and efficiency. As mentioned, the cartridge filter is one of the most preferable as it meets all criteria that best align the pool needs.

Conclusion

Above-ground pool filters keep a pool clear of dirt, debris, and other contaminants. Water is transported to the filter, with the help of filters like sand, D.E filter, and cartridge returns clean water to the pool. Size and location is the main difference between both ground and above pool filters.
