GOOD RULES OF FILTRATION-the essence of the large swimming pool water
Contact limited pool maintenance www.pool-maintenance.co.uk
Filtration Media:
The largest single surface area exposed to contamination in a pool is the media within the filter units. Arena has been used for 150 years as a filter medium. Arena also is classified as a carcinogen grade 2, due to free silica content. Each cubic meter of sand has a surface area of 3000 square meters and is an established fact that the media provides a base of sand very suitable substrate for bacteria, with all the potential health risks it generates. Arena will become extensively colonized by a variety of bacterial agents in a few days and can not be completely cleaned, even with chlorine and other standard practices.
The alginates excreted by these bacteria glue sand grains together and prevent the filters to work efficiently. The bacterial colonies are then combined to produce bio-films. A bio-film creates its own environment with low pH, thus becoming a primary source of the tri-chloramine production, the main cause smell "pool." The units of the effective operation and maintenance of the pool filter to prevent unacceptable levels of bacterial growth and tri-chloramines production should therefore be a high priority for all operators of the pool. media of sand should be completely replaced every 5-7 years.
standard codes of practice:
All commercial and public organizations have a duty of care to its employees and the public in general and the fact that right due to poor work practice can be a costly business as demonstrated in several recent cases. Therefore, it is essential that the filters are fit for purpose, well maintained and well inspected by a person with relevant experience at least once a year. Mishandling of the filters may cause problems few days. Attention should be paid to: the quantity and quality of sand, under drains and corrosion. unusual signs such as cracks, uneven bed, "" ball clay, need for research, etc.
Flocculation / coagulants are recommended as part of their filtration system (if you're not getting using already) as they bring contaminants out of solution and clump together into a floc which can be more easily removed by a filter. They are especially important in filtering Cryptosporidium and Giradia.
NEW Media Technologies: The Case of the means of glass
glass media recycling has been proven by independent studies of the leading experts in the field of water filtration, as a means of high efficiency filtration by sand. We Pool maintenance and service, I think the commercial pools should be changed to glass media as soon as possible. This change will result in the pool water significantly better environment and billiards, as well as achieving savings in operational costs and a better environment in your pool. Besides the positive environmental issues Using a recycled product, the greater operational efficiency and significantly help to contribute to any scheme to reduce the carbon footprint or objectives area applies. A study by Aqua Enviro leading experts conclude:
"In order to reprocess the recycled glass to PAS Standard of approximately 73 102 kg of media Co2/tonne occurs Co2/tonne compared to 2 kg of silica sand. However, when the benefit of application is taken into account, this work has shown that replacing the sand with glass as a filtration media offers savings that can amount to as much as 1261 kg C02/tonne/annum of the means of production, resulting in a substantial net environmental benefit. C02 These savings arise largely from the superior Performance of glass and subsequent times reduced pump performance. "
Independent studies have shown that the media has the following glass features and benefits, cleaner, lighter weight, and highly angular crushed recycled glass provides an astonishing 25% improvement in turbidity removal on silica sand. glass filtration media generally removes finer particles from water than silica sand equivalents. Glass filter media loading weak negative surface keeps the fine particles and positively charged iron and manganese ions that flow easily backwash. Crushed filter media glass is less likely to block or channel the silica sand. Glass filter media does not contain crystalline silica, resulting in better lung protection for employees and a much healthier environment. Glass filter media grains are amorphous, smooth particles that have a superior wear resistance and not permanently trap bacteria in the cracks. Using glass filter will reduce their consumption of chlorine and coagulants. media of glass gives better performance for pressure or gravity flow filters. Weighing 20% less than sand, glass filtration media provides more filter volume per kg. Glass density filtration media minor requires up to 20% less media to fill your cup filter. Better back-washing permeability up to 25% less water, saving downtime and water and sewerage charges. Using crushed glass filtration cleans better, save energy and operating costs
Finally, we emphasize that the use of an effective media product from recycled glass is a much more environmentally friendly option than to continue the use of sand and gravel quarry.
In summary, the glass media is a more efficient than sand, therefore, under careful management of water and filtering program that can produce cost savings for your pool. Once installed, we suggest you carefully monitor your pool to produce the system of water quality more efficiently. We believe that you will have excellent results and soon discover that there are savings to the water, energy and chemical use
With all these factors in mind, we invite you to make the change from sand to glass, monitor the results and reap the rewards.
Swimming Pool Maintenance Ltd now offer replacement filter with two types recycled glass media and can advise on the overall benefits and savings associated with each.
Glass DURAFILTER media:
Specially developed for installation and placement in swimming pool filters, DURAFILTER is 100% recycled glass. It is completely safe for use and conforms to British standards PA102. It is nontoxic, nonabrasive. In case of any leak in the pool than do more harm than the traditional arena. DURAFILTER media recycled glass will last a minimum of 10 years without refueling. It is our belief that the practice Sand right to refresh every 5 years. It is used in filters treated with our own high-performance coatings will provide you with a bending 10-year warranty and the life of their media.
The price barriers in the past have been the installation of the media, however glass Media DURAFILTER get recycled glass to be completely comparable in cost to the sand.
DURAFILTER glass media is an efficient the media more sand, so a program of careful water management can produce cost savings for your pool. Once installed on the filters we suggest to carefully monitor your pool to produce the most efficient water quality regime. We believe that you will have excellent results and soon discover that there are savings to do in the water, energy and chemical use
DURAFILTER is a low-cost entry into the media using glass which means that for the same price as a cargo operator of sand from the pool can get the benefits of using glass media.
POOL MAINTENANCE AND REPAIR APPOINTMENT OF REFORMS FILTER WITH BASE AS ARENA AS + DURAFILTER allowing you to make the choice that suits your budget.
