Degreasing bath treatment Ultrafiltration is established for a long time for applications like treatment of emulsions, degreasing baths or craft detection oils. With ultrafiltration, oil and dirt particles are separated. So, the particle-free filtrate can be used for degreasing again. According to the recommendations of suppliers for degreasing chemicals tensides are added to the degreasing bath. So, lifetimes up to 3 to 6 months can be reached for degreasing baths. Osmo Membrane Systems GmbH offers an upgrade for your degreasing plant in replacing the polymer pipe modules by ceramic modules. Ceramic modules are more temperature resistant, chemical resistant and changing pH-values. On the one hand, the separation efficiency will be increased and on the other hand, the lifetime of the degreasing plant will be increased significantly, because polymer modules have to be changed much more, depending on the application. The costs for the upgrade are equal to the costs for working with poly

Disposal of oil emulsions by ultrafiltration Increasing disposal costs and laws about oil disposal make a treatment of oily emulsions right necessary right where they come up. The main target of this treatment is the reduction of waste volume as much as possible. Ultrafiltration is one possibility to separate even stabile emulsions. Like chemical methods and flotation, ultrafiltration can not be used as stand-alone solution. Only by an effective pre-treatment and a pre-treatment of the oily concentrate, an optimized and economical emulsion disposal can be guaranteed. By the pre-treatment, coarse particles and free oil is separated; the pre-separation dewaters and concenctrates the flow, which comes as concentrate from the ultrafiltration. So, a maximum of dewatering and concentration of the oil can be reached. The emulsion is pumped through the membrane modules of the plant. On the membrane surface, oil is separated from the waste water. Waste water will pass the membrane and is colle

Ultrafiltration of kathodic deposition paint The filtrate of the ultrafiltration is added to the immersion bath by a spray ring, which is installed directly over this bath. So, the recovery of the remaining color is possible and by separation the color particles, painting defects can be avoided. In the last spray zone, organic solvents from the ultrafiltration are washed away be demineralised water. Concentrated with these solvents, the water is leaded into the color bath. The process is a closed loop without any waste waters. The paint bath can be contaminated with pre-tretment chemicals like e.g. phosphates, chlorides, chromates. so, a part of ultrafiltrate has to be leaded out to avoid concentration of the paint bath with these chemicals. If no ultrafiltration is used, big amounts of waste waters will arise, which are difficult to dispose. Our ultrafiltration plants are customized in membrane are, retention rate and membrane type.

Rinse water treatment with nanofiltration (NF), reverse osmosis (RO) or electrodialysis (ED) By treatment with nanofiltration, reverse osmosis and electrodialysis, your rinse water can reused a couple of times. By the membrane plant, the pollution of the rinse water is separated and the particles are concentrated. Thereby the water costs and the disposal costs can be minimized. Additionally, materials in the water can be recovered much more easier by concentration.
