Swimming Pool Sand Filter For Wastewater Treatment Plant

Swimming Pool Sand Filter For Wastewater Treatment Plant

There are three basic choices when it comes to swimming pool filters: sand, cartridge and diatomaceous earth. Each type of filter has its benefits and drawbacks, and each is effective. To choose the best swimming pool filter for your situation, it helps to understand how each works and their advantages and disadvantages.

Sand filters are very common, easy to understand and use and inexpensive. They are considered the least effective type of filter, but are still incredibly popular. The swimming pool filter is filled with sand. Pool water is pulled into the filter and pressed through the sand. The sand filters out particles from the water.

After the water has passed through the sand filter, it flows back into the pool. Swimming pool filters containing sand can be cleaned by backwashing the sand, or, if the sand becomes exceptionally dirty, by replacing the sand in the filter, which is relatively inexpensive. The main drawback of the sand filter is that it allows some particles through the sand, back into the water.

Cartridge filters are another type of filter. These swimming pool filters clean as the pool water filters through the filtering material. The filtering material captures particles and releases the cleaned water back into the pool. Cartridge filters are a popular choice for many pool owners.

There are two basic types of filters that are available to fit into cartridges. The first are very inexpensive and will need frequent replacement. The second type is more expensive, but lasts a great deal longer. The more expensive cartridge filters can last for many years without needing replacement.

If you choose a cartridge filter, whether an inexpensive or expensive one, it will require some maintenance. When the filter becomes full of debris, it becomes much less effective. You should plan to remove the filter and gently spray it clean with a water hose once or twice over the course of each swimming pool season.

If you are constantly using your swimming pool it may be a good idea to check your cartridge filter to see if it needs to be replaced or cleaned. Filters should generally be replaced every few years and they can be cleaned every four to five months. The easiest way to really know if you filter needs to be changed is by testing the pressure. You can test your pressure by checking to see how the water is circulating throughout the swimming pool, if you have noticed circulation dwindling then you can bet that its because of the filter. If you just need to clean your filter you can use an alkaline-based solution that will kill any germs or bacteria. If you are using a sand filter then the sand should be replaced once every 18 months and the filter should be backwashed every week in order to clean the sand.

As your pool filter becomes clogged with waste and debris, the pressure increases and the water flow lessons. This requires the pool owner or operator to backwash every few weeks, depending on the water flow.

Please remember that excessive backwashing may cause a loss of sand which in turn will reduce the effectiveness of the sand filtration process. Please be aware of proper pool sand filter maintenance. The proper amount of sand should be measured from the top of the filter. Follow the manufacturer's instructions.

Should you find your sand filter low, simply get the proper grade of sand and top off the filter following the manufacturer's instructions.
