Conserve swimming pool water by using a post filter, filtering bag

With water use restrictions relating to swimming pools increasing, the use of an accessory, post pool filter, system can save hundreds or even thousands of gallons of water each year. Due to debris in a pool from the off season, many people drain and refill their pools. Any algae blooms are dealt with by adding a chemical agent that causes the algae to sink to the bottom. Due to the fact that standard pool filters have difficulty capturing the dead algae and other microscopic debris, this debris is then "vacuumed to waste". This result in hundreds of gallons of chemical laden water to be unnecessarily dumped outside of the pool. This process can be time consuming and requires chemical levels such as PH and chlorine PPM to be adjusted to levels compatible with the process.

An alternative that does not result in any water loss is a high capacity, microfilter attached to the return/intet(s) of the swimming pool. The filter is in the form of a bag with a narrow neck, allowing connection to swimming pool return/inlet plumbing. The debris that is able to pass through the main filter is captured by the one micron filter fabric of the bag. This filtration level is better than even the best standard swimming pool filters and results in a capture rate in the area of 95%.

In extreme cases, the micro filter bags will need to emptied and rinsed as they begin to block up and build internal pressure.

Added benefits are that the organic material is removed from the pool and takes away the nutrients that algae feeds on. A reduction in chemical use can also be realized as the sanitizer in the swimming pool has less material to have to react with. The cost savings of using a filter bag can be substantial.
