microbial detection for cataphoresis





aqua-tools Rapid Microbial Solutions provides rapid analysis solutions for evaluating the biological contamination of cataphoresis solutions and other fluids used for surface treatments.

Cataphoresis (or cationic electrodeposition) is a high performance surface treatment commonly used in the automotive industry, mechanization and street furniture manufacturing. It involves immersing a metallic object (connected to a cathode) in a bath containing an active water-soluble compound (such as paint or anti-corrosion enamel) dissolved in water and applying an electric current from the anode to the cathode. The suspended (charged) particles are deposited on the surface of the object to create a uniform, ultra-resistant adherent film. Cataphoresis is both economical (high throughput, minimal loss of active compounds) and environmentally friendly, as water is typically used as the solvent.

Cataphoresis technology involves many steps that use a large volume of water, including pretreatment phases (sanding-degreasing, rinsing, high pressure washing, phosphatation-refining, rinsing) and post-treatment phases (rinsing, high pressure washing). Cataphoresis also requires the use of a significant amount of deionized (or reverse osmosis-purified) water and a system for recapturing and treating used water before discharge into the environment or recycling within the factory.

Contamination of treatment water

Cataphoresis fluids and other similar solutions contain high levels of water and water-soluble organic compounds, which provide optimal conditions for the growth of micro-organisms.
