With more than 25 years of experience as a specialist in clean processes and membrane separation, Applexion has expertise and skills across the entire mechanical surface treatment chain. We offer highly flexible solutions with a wide range of organic membranes (Pleiade®, Pleiade®MP4, Persep™), inorganic membranes (Kerasep™, Carbosep®) and standard UF skids.

Our Applications:

Degreasing

Before being painted, parts must first be cleaned. This process requires large quantities of water and degreasing agents and this generates substantial volumes of oily waste water.
Non-regenerated degreasing bath causes technical problems (poor parts quality) and raises environmental concerns (generation of high effluent volume).

 

They also increase costs because the contaminated effluent has to be disposed of and the degreasing agents consume large quantities of water.

With Applexion ultrafiltration solutions, you can:

• Recycle degreasing baths without interrupting production, while maintaining degreasing process quality or produce continuously, while maintaining constant degreasing process quality.
• Concentrate solutions to reduce effluent volume
• Recycle the degreasing solutions to save water and products and reduce waste

Case studies: degreasing bath
The example shows a degreasing bath treatment system with a capacity to handle 1,500 m³ per hour of metal parts coated with 2 g/m³ of oil.
Total volume of the baths: 45 m³
Effluents: oil and water emulsion, grease remover

Toward "zero waste" in the automotive and finishing industries:
Today, car makers and original equipment manufacturers face a dual challenge: limiting waste to meet increasingly strict environmental standards, while improving the anti-corrosion and paint finish of car bodies, household appliances and other products.

Applexion offers a broad array of capabilities to serve the automotive and OEM industries:
Applexion regularly develops new products and processes to help car makers and OEMs trend towards "zero waste" on all their surface treatment lines, from degreasing to paint bath recycling. These processes are technically efficient, with the ability to fully recycle both water and products (paint pigments, surfactants, etc.). They are also cost effective, with a return on investment in less than one year.
