PTH water improvers

Technical Info

What is the PTH Water Improver?

The PTH product is particularly suited to combat and eliminate the adverse effects of hard water, causing what is known in South Africa as ‘kalk’. The PTH can deal with any amount of ‘kalk’, as well as rust in pipes and fittings, algae and mildew. If the water is brackish, i.e. salty, but drinkable, then the PTH may also improve the taste.

PTH stands for ‘Protection against Total Hardness‘. As the name suggests, it is a water IMPROVER – not merely a filter.

The PTH Water Improver consists of two parts: a cylinder made from stainless steel and an inner core made from an alloy of noble and semi-noble metals. The PTH device is installed on your water line immediately after the water-meter, and is connected to the earth grounding.

The noble and semi-noble metals of the core alloy are nonferrous and highly resistant to rusting and corrosion. The PTH is non-toxic and ecologically friendly, has no amortization and lasts indefinitely.


The PTH acts as a catalytic converter

The PTH is a catalytic converter which causes an electro-chemical reaction in the water as it passes through the device.

PTH provides electrons to the water solution in a catalytic manner to reduce electron deficiencies in the water. This enables electro-chemical changes to occur. Scale binders, rust and corrosion particles are put and kept in colloidal suspension by providing them with negative charges.


The working principle of PTH is based on 2 effects:

One. The Venturic Effect
The inner core and the cylinder create a potential difference (because of the combination of different metals) that neutralizes the scale forming minerals in the water, thus preventing precipitation.
These fields and the venturic effects stemming from the unique configuration of the core prevent the adhesion and cohesion of the waterborne mineral particles (mainly carbonic salts, calcium and magnesium) that form scale.

Two. The Hydro-dynamic Effect
When the water flows into the PTH cylinder, the venturic shape of the inner core, with its embedded flow-lanes, alters the adhesion and cohesion of the waterborne mineral particles.
The electro- and hydro-dynamic forces separate the molecules, especially aluminum and silica, which bind mineral particles. The mineral particles then flow through the water system without precipitation or interference.


The PTH Water Improvement Process

Basically, the PTH ‘scrubs’ the water. This is a completely natural process which occurs freely in nature. For example, a stream or river flows over a bedrock containing 2 or more different types of metals, noble or semi-noble minerals.

Before and After

Water inlet:
• A hard water sample is viewed through an electronic microscope.
• Adhesive components are clustered around mineral particles.
• Note how the minerals and salts are bound together in a cohesive mass.

Water outlet:
• After PTH treatment you can see the precipitated mineral particles.
• Mineral particles are free of adhesive components.
• Note the separation into “individual” mineral and salt particles.

It is also important to note that when PTH is used for irrigation, the PTH effects the movement of minerals in the soil solution. In addition, the changes the PTH causes in the soil solution improves mineral absorption.

It is therefore, an entirely ‘green’ process which does not harm the environment. In fact, the PTH is eco-friendly and healthy for the environment.
