Pure Water Window Cleaning

Water-fed poles and "pure water" window cleaning Washing Techniques

What is pure Water? Pure water is the state in which minerals such as Calcium, Sodium, Iron, Copper and Chloride, etc... have been removed and has zero parts per million of dissolved solids. The safest (usually no ladders) most pure and environmentally friendly way to clean windows.

The process is the safest, most environmentally friendly, and fastest growing method used. What happens is that by using pure water to rinse down glass, after agitation of the surface to loosen the dust and grit, this leaves the glass clean and "spot-free". There are two main ways of producing "pure water," reverse osmosis and deionization. Our equipment has taken this a step further and added a Carbon filter.

Three stage water filtration system

Water quality and purity is measured by its Total Dissolved Solids. Water will leave marks on glass from 30-40 parts per million (ppm). Often tap water will have a reading of 700 ppm. In window cleaning, pure water is generally applied through a brush on a pole. All of the surface of the glass is agitated with the brush, which is then lifted from the glass, allowing the pure water only to rinse the glass, carrying all the grit down and off the glass. The glass is then allowed to dry "spot-free".

Safety is another major benefit of water-fed pole work as the operators rarely leave the ground. Often, there is no need for detergents to be used, increasing the Green Factor. Pure water cleaning is rapidly gaining popularity within the window cleaning community because of itsĀ time savingĀ over ladder use and the associated safety factors from OHS.

Stage one - Carbon filter:

Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, using chemical adsorption. Carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. This is where Step Two come in to play.

Stage two - Reverse Osmosis:

Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from water by applying pressure to the water when it is on one side of a selective membrane. The result is that the impurities are retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective," this membrane does not allow large molecules or ions through the pores (holes).

Stage three - deionized water filter:

Deionized water, also known as demineralized water, is water that has had its mineral ions removed, such as sodium, calcium, iron, copper, chloride and sulfate. Deionization is a chemical process that uses specially manufactured ion-exchange resins which exchange hydrogen ion and hydroxide ion for dissolved minerals, which then recombine to form water.

All told, this three stage filtration system is the finest in the industry. It cleans the water to ZERO parts per Million; "PURE WATER" for a clean spot free environmentally friendly shine.

Traditional Window Cleaning Methods

We also offer the traditional method of using bio-degradable soaps, squeegees, extension poles, ladders and many other tools for the trade.
