When using a high pressure washer and then reclaiming, all of the contaminants ( ink
and emulsion) removed from the screen by high pressure come off in a solid form. As a
solid these contaminants can easily be removed from the waste stream by mechanical
filtration methods sending purified water to the sanitary sewer. High pressure reclaiming
also allows wastewater to be recycled, this is crucial for those printers that are not on a
city sewer system ( sanitary sewer ). Chemicals and contaminants from the reclaiming
process can kill a septic system allowing the drain field to plug up and ground water
contamination to exist.
