For swimming pool filtration first we use sand filter to remove smallest debris and sediments from your water which comes in pool through human contact and other modes like rain and air. Basically, water flows into the top of the filter housing and makes its way down through the sand bed where the sharp edges of the sand catch the dirt. Sand filters certainly are efficient enough to keep just about any pool clean if we provide it maintenance properly .Maintenance means backwashing where the flow of clean water is reversed back into the filter.

To enhance the filtration, we normally use Alum and /or poly electrolyte in the feed to the sand filters.

• Decrease in chlorine use
•  Improval of the filter and coagulant capacities. This leads to a reduction of coagulant use  and less backwashing of the filter is required
• Water use can be decreased, because of an increase in water quality
• Ozone oxidizes organic and inorganic matter in the water, without the formation of unwanted byproducts, such as chloramines (which cause a chlorine-scent)
• Chlorine scents can be fully diminished by ozone application
• Ozone is a more powerful oxidant and disinfectant than chlorine. Certain chlorine-resistant pathogens

Chlorine is regularly fed into the pool water and should be tested daily — at a minimum — for proper disinfection. Routine chlorination kills harmful microorganisms that can cause health-related problems, such as gastroenteritis, Legionnaires disease, ear infections and athlete’s foot. Learning how to properly test your water will allow you to identify the chlorine residual and demand in pool water. More frequent testing is needed if there is heavy bather use.
