Normally there are following basic problems encountered in the maintenance of swimming pools.
  1. Growth of bacteria, viruses and other microbes on the surfaces of the swimming pools and its water exposed to air which may cause infection and diseases to the swimmers.
  2. Due to use of water by swimmers harmful bacteria germs get transmitted into water and become source of many water borne diseases.
  3. Contamination of water from oils, perfumes, urination etc. imparted into the water from the body & hairs of the swimmers makes water unfit for further usage over a few cycles.
These are the reasons why swimming pools require regular and effective treatment by disinfectants. Chlorine is a time tested and trusted sanitizer. It destroys microorganisms and protects swimmers from diseases.
 
Aquafit is a dry form of Chlorine and is very safe to handle. It is readily soluble in water and is free from any organic substances. Its pH of 10.8 helps to maintain optimum pool water pH of 7.2 to 7.6. When using Chlorine gas or Tri chloro Isocynurate (TCCA) products for swimming pool sanitization, the pH drops and leads to corrosion of pool surfaces. Due to these reasons Aquafit provides better protection for concrete, plaster, pipes and other pool equipment.
 
Aquafit – The preferred choice for residential swimming pools.
  1. It acts as a bactericide, germicide and algaecide and can be used for disinfecting and cleaning purposes.
  2. It is a strong oxidizer and can easily destroy organic body oils and other organic debris if any present in the swimming pool water.
  3. Aquafit contains easily soluble granules.
  4. Due to very less exposure of residential pools to the sunlight loss of chlorine is negligible. Hence, there is no requirement of stabilizers such as Isocyanuric acid which further contaminate the water.
  5. It provides crystal clear and clean pool water.
  6. Chemistry of Aquafit is favourable in maintaining water balance. It works to maintain properly established alkalinity levels without further chemical addition.
Aquafit – Most Suitable, Sanitizer and Versatile for Super Chlorination (Shocking) of Commercial Pool Water :
  1. Aquafit is very good for shocking to destroy chloramines.
  2. Aquafit chlorine is unstabilized and hence there is rapid growth of residual chlorine level into water, which is needed for super chlorination.
  3. Aquafit excess chlorine is reduced faster to make swimming pool available to swimmers in a much shorter period of time compared to one superchlorinated with Trichlor containing Isocyanurates.
  4. For routine sanitization also Aquafit is used in all commercial pools with added safety by adding stabilizer separately to minimize the loss of chlorine due to exposure to sunlight almost by 50%.
  5. It’s higher alkalinity works as a buffer and helps to keep the pH stable when any acidic material is introduced into water. It is also an important factor in preventing water from turning cloudy and keep the pool water clean and clear.
  6. Calcium hardness protects the pool equipment and “Aquafit” contains calcium.
Swimming Pool Water Disinfection
 
"For a new pool or spring start-up superchlorinate with 10 to 20 oz. of product for each 10,000 gallons of water to yield 5 to 10 ppm available Chlorine. Check the level of available Chlorine with a test kit. Adjust and maintain pool water pH between 7.2 to 7.6.To maintain the pool, add manually or by a feeder device 2 oz. of this product for each 10,000 gallons of water to yield available Chlorine residual between 0.6 to 1.0 ppm by weight. Stabilized pools should maintain a residual of 1.0 to 1.5 ppm available Chlorine. Test the pH available Chlorine residual and alkalinity of the water frequently with appropriate test kits. Frequency of water treatment will depend upon temperature and number of swimmers.

Every 7 days, or as necessary Superchlorinate the pool with 10 to 20 oz. of product for each 10,000 gallons of water to yield 5 to 10 ppm available Chlorine. Check the level of available Chlorine with test kit. Do not re-enter pool until the Chlorine residual is between 1.0 to 3.0 ppm.At the end of the swimming pool season or when water is to be drained from the pool, Chlorine must be allowed to dissipate from treated pool water before discharge. Do not Chlorinate the pool within 24 hours prior to discharge.

Winterizing Pools – While water is still clear & clean, apply 0.6 oz. of product per 1000 gallons while filter is running, to obtain a 3 ppm available Chlorine residual as determined by a suitable test kit. Cover pool, prepare heater, filter and heater components for winter by following manufacturer’s instructions.

Spas, Hot-Tubs, Immersion Tanks Etc.
Spas / Hot Tubs - Apply 0.5 oz. of product per 500 gallons of water to obtain a free available Chlorine concentration of 5 ppm as determined by a suitable Chlorine test kit. Adjust and maintain pool water pH between 7.2 and 7.8. Some oils, lotions, fragrances, cleaners etc. may cause foaming or cloud water as well as reduce the efficiency of the product.
To maintain the water, apply 0.5 oz. of product in 500 gallons over the surface to maintain a Chlorine concentration of 5 ppm. After each use, shock treat with 1.5 oz of this product per 500 gallons of water to control odor and algae.

During extended periods of disuse, add 1.5 oz. of this product daily per 500 gallons of water to maintain a 3 ppm Chlorine concentration.

Hydrotherapy Tanks -Add 1 oz. of this product per 1000 gallons of water to obtain a Chlorine residual of 1 ppm as determined by suitable Chlorine test kit. Pools should not be entered until the Chlorine residual is below 3 ppm. Adjust and maintain the water pH to between 7.2 and 7.6. Operate pool filter continuously. Drain pool weekly and clean before refilling.

Sewage and wastewater effluent treatment The disinfection of sewage effluent must be evaluated by determining the total number of coliform bacteria and / or faecal coliform bacteria, as determined by the Most Probable Number (MPN) procedure, if the chlorinated effluent has been reduced to or below the maximum permitted by the controlling jurisdiction. On the average satisfactory disinfection of secondary wastewater effluent can be obtained when the Chlorine residual is 0.5 ppm after 15 minutes contact. Although the Chlorine residual is the critical factor in disinfection, the importance of correlating Chlorine residual with bacterial kill must be emphasized. The MPN of the effluent, which is directly related to the water quality standards requirements, should be the final and primary standard and the Chlorine residual should be considered an operating standard valid only to the extent verified by the coliform quality of the effluent.


The following are critical factors affecting wastewater disinfection.

Mixing: It is imperative that the product and the wastewater are instantaneously and completely flash mixed to assure reaction with every chemically active soluble and particulate component of the wastewater.
Contacting: Upon flash mixing, the flow through the system must be maintained.
Dosage / Residual Control: Successful disinfection is extremely dependent on response to fluctuating Chlorine demand to maintain a predetermined, desirable Chlorine level. Secondary effluent should contain 0.2. to 1.00 ppm Chlorine residual after 15 to 30 minute contact time. A reasonable average of residual Chlorine is 0.5 ppm.


Sewage and wastewater treatment

Effluent Slime Control - Apply a 100 to 1000 ppm available chlorine solution at a location which will allow complete mixing. Prepare this solution by mixing 2 to 20 oz. of this product with 100 gallons of water. Once control is evident, apply a 15 ppm available chlorine solution. Prepare this solution by mixing 0.3 oz. of this product with 100 gallons of water.

Filter Beds - Slime Control: Remove filter from service, drain to a depth of 1 ft. above filter sand, and add 16 oz. of product per 20 sq. ft. evenly over the surface. Wait 30 minutes before draining to a level that even with the top of the filter. Wait for 4 to 6 hours before completely draining and backwashing filter.
