Brighter clearer pools.

Looking after the environment and swimmers

The environmental impacts of maintaining pools should be at the fore front of the decision-making process. When using CMZeolites for pool filtration media, pools can be operated more efficiently, safely and most importantly more environmentally. 

Pools are mainly a concoction of chemicals, large volumes of water and are powdered mostly or in part by electricity, both of which are scarce and infinite resources. When backwashing occurs this chemically infused water is then pumped through waterways, contaminating them along the way. 

Each input used for pools the chemicals, filters, filter media, pumps, power and water, need to be sourced, manufactured, processed, packaged, marketed and transported, which all has an affect on the broader climate and the environment.

How can natural CMZeolite help be the change?

  • 20% less product is needed then sand, meaning a 20% reduction in inputs and their effects on the environment.
  • The high surface area of zeolite enables more and finer particles to be trapped both physically and chemically relative to sand, the shape of the zeolite granules are more effective at trapping particles than semi-smooth sand grains, getting more value for money.
  • A higher removal of ammonia and dissolved nutrients from the pool, means less chemical is needed to treat.
  • The reduction of chloramines means an increase in the availability of free chlorine, which means pool chlorine requirements and costs are reduced substantially. 
  • Zeolite buffers the pH of the water, minimizing fluctuations and the need for corrective action, this reduces inputs of expensive chemicals.
  • Zeolite media filters retains a greater volume of dirt than a sand filter, so the frequency of backwashing to clean the filter and remove the dirt is less. This is environmentally friendly as it saves valuable water and reduces electricity consumption.
  • Due to the lower density and high porosity of zeolite compared to sand, pump pressure rates are reduced resulting in electricity cost savings.
  • Zeolite promises a long life, and so replacement costs are reduced.
  • Reduction in reheating costs due to less water wasted in backwashing.
  • Lowers operating pressures, requires less back washing, filters more efficiently, removes dissolved nutrients and subsequently lowers power, chemical and water usage for the pool
  • Less eye, ear and skin irritations for swimmers as less chemical is needed.
  • Removal of odours and bad tastes improves experience for swimmers.
  • Decreased staining means the pool visibly looks better to swimmers. 
  • Used zeolite granules can be utilised as a valuable garden fertiliser and other uses at end of life that benefit the environment does not pollute it

The science in how CMZeolites works.

Zeolite is a natural mineral that has both unique particle shapes to physically filter and a unique, negatively charged honeycomb crystal structure to chemically filter. This open crystal structure acts like a ‘molecular sieve'. The negative charge results in a selective adsorption of positively charged compounds (ions) dissolved in the water. In particular the ammonium ion is selectively absorbed onto the zeolite resulting in a reduction and better control of the build-up of nitrogen contaminants (bacteria food, source of odours) in the pool. 

How to use CMZeolites in filters?

  • Zeolite is less dense than sand, therefore use approximately 20% less zeolite by weight than is stated for sand.
  • The filter should be filled to the manufacturers’ stated capacity.
  • Backwash until all the water coming out is clear. Then rinse and filter as with sand.
