Water Softener

Water Softener RUNXIN 63B1

Solve your water hardness and scale problems the efficient way and save money!

Many water supplies in South Africa have damaging levels of calcium and magnesium making up hard water.  This hard water will cause scale build-up on your plumbing and fixtures. It also shortens the life of clothes and other fabrics.  At Absolutely Water we only use the best combination to build a water softener that will soften your water effectively.  Using the high quality RUNXIN 63B1 control valves and brine tanks and high quality softening resin, we give you one of the highest rated systems on the market.

We have softeners to fit any size home or any water treatment need for small commercial use.

Get rid of scale and rust cost-effectively

It is easier to protect your appliances from scale build-up than you can imagine.

Siliphos has been serving the water industry for more than 30 years and is an economic and reliable water treatment system for potable and industrial water.  Polyphosphates have long been used as an alternative form of hard water treatment.  It is a soluble mineral compound which acts as a sequestering agent when added to water.  Sequestering is simply the ability or tendency to tie up and hold in solution other minerals such as scale causing minerals which make them more water soluble.  Therefore, the hard minerals act soft and remain in solution, as opposed to depositing scale.

Experience shows that scale and corrosion are not only found in galvanized but also in copper pipes.  Siliphos will successfully remove and prevent scale forming and rust.

Siliphos ingredients are safe for human and animal consumption and comply with the WHO as well as NSF Standard 60 of the USA.  Siliphos is colourless and odourless.

Iron Man

Iron Man

IronMan Catalyst is formulated from manganese ore and activated in special proprietary furnace which is capable of removing iron, manganese, aluminium salts, tannins, chlorides and hydrogen sulphide from water through oxidation and filtration.  Soluble iron, manganese etc. are oxidized and precipitated by contact with higher oxides of manganese on the IronMan granules.  The hydrogen sulphide is eliminated by oxidation to sulphate and an insoluble precipitate. Precipitates are then filtered and removed by backwashing.

IronMan can be cleaned by vigorous backwashing.

Note:  it is important that the IronMan media has suitable under-bedding and attention must be paid to the configuration of media bed depths and area.

Klorman Chloronator


The Klorman is a compact, easy to install, easy to use chlorinator that converts feed-water into a continuous stream of active chlorine sanitizer.  Klorman is ideal for any application where viruses, bacteria, fungal spores and protozoa need to be controlled.  In most processes, only 10% of water used is usually responsible for 90% of all sanitation problems, and experience has shown that to chlorinate all input water at a single point in a facility is simply not the answer, since sanitation requirements vary for different applications.

The unit dispenses mild calcium-based chlorine that forms a sanitising solution which is non-corrosive, pH stable and environmentally safe.


Water Treatment

To treat specific problems in water, we have softeners and siliphos for lime scale treatment and chlorinators for bacteria and virus removal.
