How Swimming Pool Disinfection Works

The Watermaid salt chlorinator makes its own chlorine for swimming pools by converting mild saline pool water (about 1/6th the concentration of seawater) into chlorine.

The process of electrolysis splits the salt molecule (sodium chloride) into sodium and chlorine. At the same time a hydrogen atom is freed up from the water molecules. This produces sodium hypo chlorite (liquid chlorine) for your swimming pool. Sodium hypochlorite is chlorine in a usable form, which purifies and sterilises the pool water.

The Watermaid chlorination system will drastically reduce purchasing or adding sanitizing chemicals such as liquid or granular chlorine. It will also minimise the hazards of handling and storing of chlorine chemicals.

The Watermaid Disinfection Alternative Keeps Your Pool Clean

Not only will you have the peace of mind that the Watermaid chlorination system is keeping your pool, clean clear, sparkling and sterile, but you will also enjoy other benefits of swimming in mild salt water, such as, no sore, stinging red eyes and no smelly or itchy skin, and bathing suits will not disintegrate .

Watermaid Chlorinators are capable of sanitizing pools up to 150,000 litres and can cope with the heaviest swimming pool, chlorine demands. The Watermaid Unit has been engineered to incorporate a fully controllable, chlorine output adjustment touch pad.

You set the amount of chlorine that your pool requires or simple select the chlorine output to maximum to super-chlorinate!

The Watermaid Unit is capable of producing 5.7 litres of liquid chlorine equivalent per day! That is up to double the chlorine production of most other brands.

Watermaid – Salt Water Chlorinator, Model: WM10LED

The Watermaid Ezyclean Cell is the only cell that is installed via a Venturi System. By mounting the cell vertically, the Watermaid system has a functional gas trap without additional water diversion and plumbing. A gas trap prevents the products produced by electrolysis from traveling down the plumbing and getting trapped under solar covers. A gas trap is mandatory on chlorinators in Australia. In North America this is not a requirement but Watermaid insists on maintaining this safety system. If water flow stopped, a gas sensing tang in the top of the cell would shut down the system. Unlike other systems, this is NOT a spring loaded switch. It has no moving parts which could calcify and prevent the switch from moving and shutting down the system. If however, our sensor ever did fail, the bubble of gases produced by electrolysis would force the water down in the cell until the active plates were no longer covered by water. At that point the reaction would stop and the gases would be “trapped” in the cell housing.

This advanced installation method results in:

  • No blockages of water flow through the main pipework due to cell calcification.
  • Reduces the chances of pump motor burn-outs.
  • Increased safety
  • Tighter installation
  • Easier cleaning
