Our water is like a calling card for the quality of our soil and bodies of water: Every region leaves its unmistakable fingerprint on drinking water. Dissolved minerals play an important role in shaping our most important foodstuff. That is why it tastes different from region to region. Calcium and magnesium are particularly important. When we refer to “hard” water, we mean a relatively high proportion of these minerals. This is measured in parts per million (ppm).
Households with a high water hardness can run into costly problems on a day-to-day basis. When hard water is heated, this causes deposits to accumulate in pipes and valves. Household appliances and hot water systems suffer from a build-up of limescale, necessitating expensive repairs and reducing the service life of appliances. In addition, deposits in the heating circuit can drive up energy costs.
Hard water can also affect our bodies. In extreme cases, it can even lead to disorders in very sensitive skin. But even healthy skin tends to tighten after showering and bathing and is prone to irritation. Hair can become dry and dull after washing while laundry can be rough to the touch and colours fade more easily.
Cleaning also becomes hard work: Deposits form wherever water flows, drips or stands. These limescale stains in the bathroom and kitchen are difficult to clean. With hard water you need twice as much detergent, skin and hair care products to achieve the same effect as you would with soft water, costing you more money.
Pure pleasure in the shower and in the bathtub, soft cuddly laundry, gleaming fittings and the icing on the cake: lower energy consumption. Softened water offers numerous advantages.
BWT has the perfect solution to this problem: Water Softener systems that transform even extremely hard water into silky soft Luxury Water. The costly everyday problems associated with hard water disappear and the feel-good factor at home is enhanced. BWT cutting-edge technology, turns every bathroom into a wellness oasis. Hair is shinier, skin becomes velvety soft and the laundry is soft and cuddly.
In addition, washing machine, water boiler and all other devices in which water is heated are protected. They work smoothly and their service life is extended. Cleaning agents and care products can be used much more sparingly. Shower walls and fittings gleam without time-consuming cleaning.

BWT water softener technology is based on a process that also occurs in nature. The process is referred to as "ion exchange". In this process, calcium and magnesium ions are removed from the water and replaced with sodium ions.
Inside the BWT Luxury Water softener systems there is resin vessel filled with a high quality ion exchange resin that enables this exchange to take place. As hard water flows through the vessel the calcium and magnesium ions dissolved in it are bound together and retained by the resin and at the same time replaced with sodium ions.
BWT cutting-edge technology ensures that this process can run completely smoothly thanks to the latest electronic control systems. Once the resin is saturated with calcium and magnesium ions, normally after a few days it needs to be regenerated in order for it to remain efficient. This involves cleaning the resin with a brine solution. All BWT water softeners in the UK are programmed so that this happens automatically at night when the household is a sleep. This process can also be set to suit individual needs if necessary. This regeneration cycle does not affect your drinking water tap.

BWT cutting-edge technology is encompassed in a wide range of domestic water softeners of varying designs and sizes. This ensures that every household will find exactly the product to match their needs. Which ever model you choose you are guaranteed a high quality product that will adapt to your lifestyle so that you enjoy Luxury Water when you need it most. Each model comes with a comprehensive at home guarantee that on some models can be extended to no less than six years for complete peace of mind.
When you filter water you normally provide a physical barrier which only allows particle of a certain size to pass through. This barrier can take many forms and can be designed to be disposable or reusable. The size of particles that can pass through are governed by the filters micron rating.
When you are softening water it is necessary to remove the dissolved minerals that cause the water to be ‘hard,’ normally Calcium and Magnesium, these ions cannot be trapped by a standard filter. So this is typically done using an ion exchange process. Softeners use millions of tiny resin beads which are positively charged to attract and retain the calcium and magnesium ions. When the capacity is reached the resin is regenerated using a brine solution and the hardness ions are washed to drain.
Hard water is water that contains dissolved hardness minerals above 100 parts per million (PPM). Relative levels of hardness have been established as:
The amount of salt used depends on many factors, including the type of water softener you choose, your local water hardness, the sort of salt and the amount of water you use. Modern water softeners use advanced metering, and algorithms to predict water usage and limit the amount of water and salt used.
As a general rule of thumb, a modern four-person family sized electronic water softener will use approximately 10 x 25kg bags per year
