What Is Pure Water?

The term Pure Water in window cleaning describes ordinary tap water that has been filtered through a purifying filter system. This removes natural minerals from the water including Calcium which is the the main cause of white spots on the window when they dry.
Water is purified through an Reverse Osmosis (RO) System or DI Vessel (De-Ionisation) or a system that combines the two technologies in a single set up.

How Do I Test Water Purity?

You can test your treated tap water with a TDS Meter which measures electrical conductivity and produces a value indicating the level of dissolved solids in the water. For window cleaning purposes, a value close to 000ppm (parts per million) of dissolved solids is low enough to leave a streak and spot free finish on the glass. It's reasonable to effectively clean windows with readings of up to 10ppm.

What Is REVERSE OSMOSIS?

Reverse Osmosis (RO) is a water purification technology that uses semipermeable membranes under pressure to remove large particulates from water. Reverse osmosis can remove many types of molecules and ions from solutions, including bacteria, and has many industrial applications. Ro systems are becoming increasingly popular in the home for producing filtered drinking water.

How Does Reverse Osmosis Work?

Reverse osmosis uses ion exclusion to force water containing undesired contaminants through a semi-permeable membrane. A concentration of ions at the surface of the membrane permits the passage of water molecules while rejecting contaminates and impurities.

In window cleaning systems, the purified water from the RO becomes ionically charged by passing it through a De-Ionisation unit called a DI Vessel. The effect is such that the water dynamically attracts dirt, dust, mineral deposits and various organic materials when applied to the surface of the window glass.

NASA Technology

The development of efficient portable water purification systems were a direct technological spin-off from scientific research following the need to effectively recycle water aboard the International Space Station. Innovations in the design of Forward and Reverse Osmosis systems and membranes combined with improvements to small powerful pumps and deionisation filters have found wide applications around the globe.

Pure Water Cleaning Systems

Custom built RO systems provide a highly effective means of removing contaminates which can compromise the effectiveness of DI filtration. However, an alternative carbon pre-filter method can be a cost effective alternative for producing ionically charged water, but in general the carbon block filters are a more effective method of removing contaminants.
