Koch Membrane Systems launches filtration product for electrocoat paint

The new Kpak plus and Spirapak plus modules feature optimised element design and construction to improve performance

Koch Membrane Systems (KMS), a specialist in the development and manufacture of membrane filtration technologies, has launched a new line of Electrocoat (E-coat) paint spiral ultrafiltration membranes offering manufacturers greater recovery of paint resin and pigments.

As an membrane technology supplier, KMS pioneered the potted spiral design for E-coat paint in 2003. This innovation provided energy efficiency, zero bypass operation and longer membrane life, as well as a simplified system design with easy and safe membrane replacement.

The new Kpak plus and Spirapak plus modules feature optimised element design and construction to improve performance while providing the same separation properties and low fouling characteristics as the traditional Kpak and Spirapak modules.

“With up to 20% higher productivity, these new products will benefit end users by improving paint yields and reducing overall operating costs,” said Taylour Johnson, Product Manager of Industrial Processes at KMS.

“The new products are a direct replacement for our previous line and do not require system modifications.”

Benefits of ultrafiltration in the E-coat process include:

Paint Recovery: Recovers up to 98% of paint solids for reuse, while generating rinse water (permeate) for use in the plant.

Paint Bath Conductivity Control: Removes excess free ions, low molecular weight resins and carry-in from pretreatment.

Hazardous Waste Minimisation: Recovers up to 98% of dragged out paint and reduces loading on wastewater treatment plant.

The Kpak plus and Spirapak plus modules, as well as the plus version of the flanged and drop-in spiral elements for E-Coat paint are now readily available in all product sizes and configurations.
