Water Treatment For The Finishing Sector


Water Treatment for The Finishing Sector – the finishing end of a production process can be one of the most demanding in terms of water volume required. Certain industries have higher demands for finishing and in order to ensure that the result of the product to the best possible standard. Depending on the finishing process, chemical,mechanical or a smart finish, certain products such as oils or substances end up in the wastewater including metals and paint residue. The proper removal of these products is vital to prevent damage contamination of local water supplies and the environment.

The finishing industry requires quality control throughout ensuring standards high surface finishing with no defects, with every metal finishing shop being unique. This incredibly broad sector covers both decorative and functional items for domestic use. This includes such diverse things as jewellery, watches etc., electrical goods, kitchenware, windows, doors and associated furniture, and many others.  Each will use different chemicals and generate varying liquid waste with metals and other contaminants. Each shop will have different waste treatment priorities arising from its own unique combination of product, specialisation, government regulation and economic factors. In the automotive sectors paint and finishing stage dominates the volume of water used and can often use more than the other stages in the plant or facility.  Poor quality water going through the can affect the quality of the finished product as well as having environmental implications. At Enduramaxx we work with a number of consultants and installers who work with developing clean water system improve the finished quality of a product and look to bring this to more clients as we work alongside them to promote better water treatment.

 The Benefits of Water Treatment Solutions

Benefits of installing a water treatment solution to your finishing processes helps to improve the efficiencies. This system should be part of pre-finishing stages (setting up, preparing chemicals and equipment), the process itself and cleaning-up of the tools used afterwards. Cost benefits can create a more efficient working system for your team, lower requirement for water, sludge reduction / waste minimisation, chemical recovery, and metals recovery

Enduramaxx works with a few water treatment finishing consultants to help your finishing process and reduce the usage of water. A correct water recycling facility installed removes harmful substances from the wastewater and treats left-over water through processes such as reverse osmosis, ultrafiltration of UV bacteria control to make the water fit for reuse. Membrane systems can remove chemicals and ultimately giving benefits inching received water costs and environmental footprint through managing your wastewater.

Top up water in finishing

Pure water is used for preparing chemicals, topping up of plating baths and for rinsing parts. PCBs, etc to ensure there are no spots on the finished coating. Different plating industries use different purity levels of water for their applications, some will take the water straight from the tap, which although this water is made for drinking, is not 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. This quality level of the water is controlled with pure water production reverse osmosis systems, de-ionising resin systems or a combination of both.

Other areas where ultrafiltration and microfiltration process are carried out include.

Food & Dairy

  • Milk/whey bacteria removal
  • Casein/whey protein separation
  • Fat/protein separation from whey
  • Milk standardisation
  • Apple juice/glucose syrup clarification
  • Gelatine concentration Biotech


Concentration & Diafiltration

  • Desalting & buffer exchange
  • Cell harvesting/clarification
  • Virus harvesting/clarification
  • Extraction/filtration of organic and amino acids


Water Treatment

  • Dehydrogenation
  • Production of high purity water
  • Treatment of process and wastewater
  • Recycling of acid and caustic solutions


From course filtration of electrolyte plating fluid with batch process filters to ensure continuity of finish to organics removal with carbon to eliminate pitting on bright finish plating, the finishing industry requires an exacting final product.  Pure water gained from either reverse osmosis systems or de-ionised resin treatment also ensures spot-free drying of PCB process and decorative items.
