Degreasing process is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials.
Degreasing treatment is performed with aid of an aqueous solution containing detergents.
The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in degreasing baths until the need for renewal and/or replacement, to avoid loss of efficacy.
Using ceramic membrane technology in dairy industry, there has two fluids, one is permeated which is constituted by water and detergents present in the original bath, the other is concentrate which contains oils and suspended solids and that is back to oil removal tank. After ceramic membrane treatment, the concentration of oil in the degreasing tank can be maintained at a low and very stable concentration range, the quality of the cleaned steel plate is uniform. The emulsion oil in the waste liquid is subjected to demulsification to reduce the amount of surfactant used in the cleaning solution.
Separation principle
Selecting the appropriate ceramic dairy membrane filtration precision, by utilizing the characteristics that oil molecules and water molecules differ by tens of times in size and hydrophilic membrane surface properties of ceramic membrane, oil molecules can be effectively rejected, and water, degreasing bath, and surfactant small molecules can be recycled through the membrane surface. The degreasing bath is concentrated by the ceramic membrane system, and the volume of the discharged waste liquid is greatly reduced.
Technical benefits
- Oil is removed and decreasing baths can be recycled ;
- Costs of adding chemicals are significantly reduced;
- The usage of surfactant is greatly reduced because of SS removal ;
- Regeneration period is prolonged to 6 months or more ;
- Subsequent wastewater treatment cost is decreased ;
- Longer service life, lower operating pressure and lower energy consumption;
- Simple, compact, fully PLC control
- Ceramic membrane has excellent chemical resistance, high-temperature resistance and high separation precision

Organic Membrane Filtration System
OMS skid-mounted (Organic Membrane Filters System) refers to a form of overall combination of equipment frame and whole equipment. Organic membrane system means that a group of equipment is fixed on the chassis and can be used after moving. It is not necessary to install valves and instruments in the middle, and it can be used by directly connecting the pipelines. OMS skid-mounted device is widely used in reverse osmosis (RO), Nanofiltration (NF), Ultrafiltration (UF) and Microfiltration (MF). OMS skid-mounted device is customized design to evaluate the performance applied in RO, NF, UF& MF.
