We stock a full range of complete softeners. Softeners can be customised to your requirement & budget.
Calcium causes scale in pipes, on appliances and most surfaces that are exposed to calcium rich water including kettles, irons and washing machines. This leads to higher heating and energy costs and expensive repairs to appliances. It also affects the taste and smell of the water. There are a number of ways to treat hard water some of which are very expensive.
The most effective and economical method commonly used to reduce hardness is to remove the calcium and magnesium ions from the water and replace them with sodium (salt) ions. The sodium ions prevent scale build-up. It is not a water filter it is an ion exchanger!
A standard water softener consists of 2 vessels. The first vessel contains a sodium coated zeolite ion exchange resin. Water under pressure passes through the resin vessel flowing over the softener resin, which makes the the calcium and magnesium ions stick to the resin and the resin puts sodium ions into the water.
Once the softener resin has reached the end of its service cycle and can hold no more calcium and magnesium, the water softener automatically starts a regeneration cycle, drawing a solution of brine from the second vessel, the brine tank, into the softener resin vessel. The brine solution washes the softener resin, causing the calcium and magnesium ions to be washed to drain, and the resin to be regenerated with sodium ions.
The softener is fitted with either a manual or automatic backwash system which rinses the resin with the salt water ready to continue cleaning the hard water. The majority of water softeners supplied are fully automatic. The only operator assistance required is the addition of salt to the softener‘s brine tank occasionally. The system also automatically adds more water to the salt in the brine tank to produce more brine for the next regeneration cycle (which is why we get an over flow in Vanderbijl – there is too much water in the salt tank).
For the norm, or average raw borehole water treatment, up to 2500lt/hr @ 4bar is ideal and for peace of mind an ultra violet light can be fitted. An ultra violet light is cost effective and a safe method to kill bacteria without using chemical substances.
Have you ever opened the tap and the water comes out white, this shows high concentration of lime in the water.
