Filter Presses for the automotive industry

Large volumes of sludge and process wastewater are generated every day in the automotive industry, for example during component pre-treatment, electrophoretic coating (e-coat), paint finishing and surface treatment processes. These process streams contain paint particles, metal hydroxides, pigments and other solids that must be separated efficiently from the process water.

 

A high-performance filter press is a key component of modern production facilities. It efficiently dewaters paint and process sludge, significantly reduces disposal volumes and enables valuable filtrate to be recovered for reuse within the production process. This lowers operating costs while conserving valuable water resources.

 

Filter presses for paint sludge and process wastewater

 

AQUACHEM designs and manufactures filter presses for reliable operation in demanding industrial applications. Our systems are ideally suited for dewatering paint sludge from wet paint booths, sludge generated during zinc phosphating, e-coat processes and a wide range of other surface treatment applications.

 

Customised filter presses for plant engineering and industrial applications

 

Plant manufacturers and industrial operators require robust systems that can be integrated seamlessly into existing production lines. That is why we work closely with plant engineering companies, system integrators and industrial customers to tailor every filter press to the specific process requirements. Whether manual, semi-automatic or fully automatic, every system is engineered to meet the specific requirements on site.

 

Membrane or chamber filter press – Choosing the right solution

 

Depending on the characteristics of the slurry, either membrane or chamber filter presses are used. Chamber filter presses provide a cost-effective solution for many applications, while membrane filter presses achieve higher dry solids content by squeezing the filter cake after filtration. This further reduces transport and disposal costs.

 

Recover process water and reduce operating costs

 

Another key advantage is filtrate recovery. Depending on the application, the clarified process water can either be returned directly to the production process or transferred to a downstream treatment stage. This helps reduce both water consumption and operating costs while supporting more sustainable manufacturing.
