Pure water is used widely for preparing chemicals, topping up of the plating baths and for rinsing parts and PCBs to ensure that no spots are present on the finished coating. Different plating industries use different purity levels of water for their applications with the rule of thumb being ‘the purer the better’.
Some will take the water straight from the tap, although this water is made for drinking and not of the purity required for most plating applications. The water quality required for plating involves producing reverse osmosis (RO) quality water or totally de-ionised (DI) water. The quality level of the water is controlled with pure water production reverse osmosis systems, de-ionising resin systems or a combination of both.
Stages of Filtration & Water Treatment
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.
Reducing the levels of bacteria to log 7
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.
SPECTRUM Standard Pressure Vessel
Lot-coded for product tracking and traceability, the SPECTRUM range of black pressure vessels, also known as DI or resin tanks, are tested to ensure product quality and reliability.
SPECTRUM General Purpose DI Resin
The high quality mixed bed resin, SPECTRUM SRDI is designed to ensure the highest capacity and most efficient operation to create pure deionised water.
