In the beginning of 2007 hypochlorite generator was replaced by AQUACHLOR-100 device at «Virgin Active» Health Club which significantly improved microbiological, chemical and organoleptic characteristics of water.

producing capacity of AQUACHLOR-100 device makes 0,1 kg/h (2,4 kg/24h) in chlorine equivalent. The device operates in automatic mode. The oxidants solution is supplied to the pool’s water circulation system from the collecting tank by dosing pump depending on the amount of residual chlorine in water. Catholyte produced by the device is mixed into the oxidants solution for pH regulation.

AQUACHLOR-100 device disinfects swimming pool of 30 m3 in volume and spa

Extract from "Instruction on application of the oxidants solution produced by AQUACHLOR devices for domestic drinking water disinfection, household and industrial wastewater treatment, water disinfection in swimming pools".

"The oxidants solution should be continuously or at regular intervals supplied to the swimming pools bowl for water disinfection. The pool’s water in this case is used for the oxidants solution generation. Chlorine concentration in the pool’s water should be within the limits of 0,3 - 0,5 mg/l. For example, in order to get active chlorine concentration of 0,5 mg/l in the pool of 100 m³ in volume it is required to supply 50 liters of the oxidants solution with concentration of 1 g/l. In the first tree days after pumping water into swimming pool the oxidants solution supply should be increased by 20 - 50%. In this case stable chlorinity (not less than 0,3 mg/l) is achieved. The oxidants solution is supplied to the pool’s recirculation system from the in-between collecting tank. Preventive "shock" water impact by the oxidants solution is carried out 1-2 times per month during the night time. The quantity of the solution should be such as to increase water chlorinity up to 1,0 - 1,5 mg/l. For example, for swimming pool of 100 m³ the quantity of the solution should be equal to 100 - 150 l. Application of the oxidants solution according to this mode does not increase the water's pH. Optimal values of water’s pH in the swimming pool 6,0 – 6,5.

The following measures are recommended to be taken before putting into operation of swimming pool’s water treatment system applying disinfection by the oxidants solution produced in AQUACHLOR devices:

1. Filtration and recirculation systems water flush containing not less than 3-5 mg/l of oxidants resulting in gradual escape of fouling from tubing and filters. Such cleaning should be carried out from 6...24 hours depending on the previous summary operation life;
2. The oxidants solution supply to the swimming pool schedule should be worked through. This schedule should provided for all alterations in the devices’ operation modes depending on change of service conditions (number of visitors, water overheating, lighting mode, duration of periods between complete change of water in swimming pool).

Near-bottom sediment (if appeared) is recommended to be removed by means of aspirating device.
