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.
