Litho printers use plate technology and reverse osmosis (RO) systems are used to produce pure RO water for rinsing the plate between uses. For further purity, deionised (DI) water is produced. This ensures consistency and quality for each print run. DI water is sometimes used to reduce the viscosity of some inks before printing and to clean equipment after printing. The high purity water is used to prevent any contaminants being added to the ink which could damage the final product and also to prevent contaminants such as hardness building up on printing equipment which again could damage/distort the final product.
DI water is also used to clean inkjet cartridges before re-filling. The DI water is warmed and then pulled through the cartridge using a vacuum. Typically, this water is bought in but some manufacturers produce their own to reduce costs.
Stages of Filtration & Water Treatment
Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.
Chlorine and Organics Removal
Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.
RO Water Production
Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.
The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.
SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Boasting WRAS approval over the ESP, the TruDepth Standard is the best value option for general particulate reduction. With a recognisable mini-grooved construction, the SSP has a higher surface area and enhanced dirt holding capacity over the TruDepth Economic cartridge (ESP).
SPECTRUM 870 Economic Carbon Block Cartridge
SPECTRUM Economic carbon cartridge removes chlorine, chemical and organic taste as well as odour and appearance removal. Great for pre-filter in applications such as RO.
SPECTRUM Reverse Osmosis System
SPECTRUM RO Systems designed for commercial & industrial operators. 4 systems available to meet RO production levels of 150 to 1250 litres per hour.
