Dewatering of Paint Sludge

Dewatering of Paint Sludge

What is Paint Sludge?

Paint sludge results from the industrial spray painting of workpieces in painting systems. Some of the paint escapes into the surrounding air in the form of a mist. The excess paint mist is called "overspray". To remove the overspray from the booth after painting, the air is usually displaced with water. The resulting paint sludge is then removed from the paint booth using suction systems.

Significant costs are incurred during the disposal of this paint sludge. In addition to the costs of disposal, the associated effects on the environment are playing an increasingly significant role.

We can help, with our innovative Flottweg Decanter Technology.

Paint Sludge Dewatering and Process Water Recycling with Flottweg Decanters

Our centrifuges dewater the incoming sludge to reduce sludge volume to as little as 10 percent of its original volume. This reduces the quantity of solids for disposal, significantly reducing operating costs.

For optimum dewatering performance, coagulants help to concentrate the paint particles. In contrast with conventional centrifuges, our Flottweg Decanters require only a fraction of the amount of flocculant for the same solid discharge.

The process water used to clean the booths is reconditioned by our decanters. The treated process water can be reused for the production process! This also saves a significant amount of fresh water.
