Reverse osmosis (RO) is a process that uses a semi-permeable membrane to remove dissolved solids, minerals, and other impurities from water. To produce pure water for window cleaning using an RO unit, the process typically involves the following steps:
Pre-filtration: Before entering the RO membrane, the water is pre-filtered to remove any sediment or debris that could damage the membrane. This is typically done using a sediment filter and a carbon filter.
Pressure pump: The pre-filtered water is then pushed through a semi-permeable RO membrane using a high-pressure pump. The membrane has very small pores that allow water molecules to pass through but block larger particles and dissolved solids.
Permeate and waste streams: As the water passes through the membrane, it is separated into two streams: the permeate, which is the purified water that is used for window cleaning, and the waste, which contains the concentrated impurities and is typically flushed down the drain.
Post-filtration: Finally, the permeate may pass through additional post-filters, such as a carbon filter or deionization resin, to remove any remaining impurities and ensure the water is completely pure.
The resulting pure water is free of minerals and other contaminants that could leave streaks or spots on windows when used for cleaning.
