Swimming Pool Sanitation

Ensuring that you keep high standards of pool maintenance is key to keeping the water sparkling clean and safeguarding yourself from infectious waterborne diseases. Adequate sanitary conditions should be of paramount importance to pool owners and whilst good swimmer hygiene practices such as showering before and after swimming will reduce the introduction of contaminants to the water, an appropriate re-circulation and filtration system is the first barrier of defence that needs to be addressed.

Re-circulation

Water pumps are a means to continuously recirculate the water contained within a swimming pool system and allow it to be heated and chemically treated. This cycle will evenly distribute the water treatment chemicals throughout the entire system and will prove to help prevent against stagnation. These pumps need to be in use regularly even during periods of non-use and can be set up to operate on an electronic timer to reduce costs. Water pumps are usually categorised by their Horse Power or Kilowatt rating. It is important to have the appropriately powered pump for your system. This will allow the water to be circulated throughout over the recommended time period of about eight hours. The quantity of water which is moved can be effected by various factors such as the resistance in the pipework which can prove to be difficult to calculate and so it is advisable to contact your local specialist for advice on your specific requirements to aid with the purchasing of the correct pump. The use of pool pumps alone, however, will not suffice in providing the sanitisation necessary to prevent diseases and quality filtration is also critical.

 

Filtration

The role of swimming pool filters is to remove the micro-organisms and various contaminants which can lead to algae and bacterial growth. There are two main types namely fibreglass and cartridge filters. The most commonly used filters are fibreglass and have the adaptability to be filled with specific materials such as graded sand which tends to last around five years until it loses its coarse nature and needs to be replaced. They operate by allowing water to pass through the sand, usually by gravity, which will intercept the dirt and debris. The pressure on these types of filters will need to be observed routinely due to the build-up of debris at the point of filtration. As it becomes saturated the pressure will become higher at the inlet pipe as opposed to the outlet and will require cleaning by backwashing which will, in turn, maintain its effectiveness. Cartridge filters utilise a porous material to capture the impurities and collect them until it will need to be removed and cleaned or eventually be replaced. Maintenance of cartridge filters is simple and inexpensive as pool owners need only remove the cartridge and clean it with a hose and cleaning products before replacing it. It is usually recommended that these filters are replaced every three to five years. Due to the nature of cartridge filters they operate at a lower pressure than the fibreglass filters which will aid the flow of water round the entire pool system.
