Mobile window cleaning system from Turkey gobbles up the dirt

Reverse osmosis (RO) is a 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 raw water is retained on the pressurised side of the membrane and the pure water allowed to pass to the other side.

To be 'selective', this membrane should not allow large molecules or ions through the holes, but should allow smaller components of the solution (such as the solvent) to pass freely.

In Bayersan's system, tap water is connected to the Mobile RO system. Water passes through prefilters, which are sediment and carbon filters. Water is then pumped (via electric or battery pump) to the industrial low pressure membrane. At the end of this process, a water purity of approx. 95% is achieved. This is already sufficient to provide streak-free window cleaning

For those working in hard water areas, a 5 litre DI (de-ionising, ion exchanger) vessel is added to the system. This is designed to remove all minerals (salts) from the water, achieving a water purity of approximately 100%.

Water quality is measured with a TDS meter (Total Dissolved Solids) in 'parts per million' of TDS. In practice, low single digits (0-6 ppm) water will dry spot-free.

The system comprises the mobile electric or battery RO system, 16m carbon fibre pole and connections, three different brushes and connections, 25 litres of cleaning fluid,
TDS meter, 50m hose, hose reel and connections
