How do Pool Filters Work?

Thursday, May 29th, 2008

Owning a swimming pool can be something of a double-edged sword – a pleasure for the cool relaxation it provides, but a burden because of the constant maintenance required. If the problem isn’t regular checks of chlorine levels, pH and alkalinity, it could just as easily be the ongoing physical clean-up you need to perform. Most people rely on pool cleaners for the lion’s share of this work, and with good reason – scavenging robots can be surprisingly effective at cleaning the walls, surface and floor of any pool. Even with so many safeguards in place, however, you still need internal systems to pick up the slack.

Pool filters are essential to reliable operation. The truth is that no matter how hard we try, it is inevitable that dust, dirt and debris will make their way into the water of any swimming pool. Leave such unwanted pollution untreated and it’s likely to accumulate rather quickly, creating cloudy water and ideal conditions for an algae population. It is for this reason that every pool sold in the United States comes with a filtration system attached. Which variety you opt for can be as much a matter of personal preference as it is necessary.

How do pool filters work? The basic operation is the same across the board – such filters operate by pumping your swimming pool’s water through some kind of barrier to trap particulates in the solution. Nearly every pool will completely cycle its water through the filtration system several times a day, and some especially busy municipal pools are required to keep the water cycling more than once an hour. Choosing which filter to buy requires that you understand something about the benefits, cost and maintenance regimen associated with each. Knowledge such as this can help you make an informed decision about how much commitment you really want to offer this machine.

Swimming Pool Facts

Cloudy water?
There are several things that you can easily do to discover why your pool has cloudy water

  • Check to make sure the pH levels are in proper range

  • Check the pool filter. Clean or replace if needed.

  • Check the pool sanitizer’s level. If it’s low, raise the level.

  • Call your local dealer from Pool People USA for additional help for chlorine stabilization, alkalinity, calcium hardness and heavy metals.

Test frequently
Depending on your usage, you should test the water frequently. Some users test the pH and chlorine every other day - others test once a week. During heavy usage and summer months, you can perform a daily test. And anytime you notice a change in water quality, get your test kit out and check the water quality.

When to clean, when to replace
Periodic backwashing will remove most dirt from a clean filter; however, over a period of time, grease, oils and scale can attack and build up on the elements. When this occurs, you should clean or replace your filter depending on the type of filter. NOTE: Check the filter if water is murky or water quality decreases.

Water clarifiers
A clarifier is designed to aid efficient filter operation by coagulating most materials that cause cloudy and hazy water. Because the presence of these materials increases the disinfectant demand, the use of a water clarifier can decrease pool maintenance costs.

Why filtration is important
Filtration is the mechanical way to remove visible matter from the water. The filter medium is designed to remove hair, dirt, tiny skin flakes, metal or calcium precipitates and other visible debris that would otherwise cause the water to be hazy and cloudy.

What does “Vacuum to Waste” mean?
When you “Vacuum to Waste” you are pumping the debris you vacuum out of the pool and sending the water to the waste line, and not through the pool filter. This method removes a large amount of water from the pool in a short time, so be sure the pool is full before you begin. Vacuum to waste is used for large amounts of debris and dirt.

The proper way to get rid of algae
First, you must add the algaecide according to the directions. If you don’t add the correct dosage amount, it won’t kill any of the algae. Also know that using the entire bottle of algaecide is ineffective. Not only will you spend additional money, large doses can lead to staining and foaming in your pool.

In addition to properly dosing your water, it is also recommended that the algaecide be added in the morning on a bright, sunny day for best results. Algae grow in the presence of sunlight. Adding algaecide during algae’s best growth time will increase intake of the algaecide and make it more effective. If black algae is present, brushing the algae at least once daily will also help expedite algae removal. Brushing the dead cells away makes the living algae more vulnerable to the algaecide.

The Absolute Importance Of Cleaning Pool Filters

Thursday, January 31st, 2008
One of the most important steps in keeping your pool clean is cleaning pool filters.

Your filter works hard to keep your pool clean and sanitary. But, if you fail to periodically clean your filter, dirt and debris can build up within.

When that happens, the filter’s ability to is impaired and can become less effective. Fortunately, cleaning your filter usually takes very little time and effort. The key is to do it regularly.

By using a “backwashing” process once a week, you can remove most of the dirt that tries to build up within the filter.

Over time, however, debris can begin to collect on the removable filtering mechanisms. This is why occasional “deep cleaning” is required.

The three types of pool filters (sand, diatomaceous earth and cartridge) each require unique steps to clean them. This is due to each filter using a unique filtering process.
