In the production process of rolling, galvanizing, spraying, metal cutting, oil and alkali refining, a large amount of oily wastewater is produced. JIUWU company has been successfully applied to the treatment of oily wastewater with ceramic membrane technology, and there are many typical cases. JIUWU company can provide the overall process package of emulsified oil wastewater treatment.
The advantages of ceramic membrane process:
Cold rolling emulsion waste water
Acid/alkaline/oxidation chemicals resistance
High thermal stability and steam disinfected
Wear ability and excellent strength
Stable over a wide pH range
Narrow pore size distribution
Easy to be cleaned and regenerated
No chemical agent, no new sludge
In order to eliminate the thermal deformation caused by cold rolling in the rolling steel production process, emulsion should be required for cooling and lubrication, thereby there are lots of cold-rolled emulsion wastewater. JIUWU company has adopted UF ceramic membrane + MBR integration technology to treat cold-rolled emulsion wastewater, which has achieved very good results.
Mechanical processing industry oily wastewater treatment
The waste liquid and washing wastewater discharged from the metal products during the mechanical processing mainly contain impurities such as oil, grease and metal ions, and are highly polluting to the environment. The ceramic membrane integration technology developed by the company can handle this kind of wastewater well.
For most of the countries, Edible oil processing units is one among the major economic zones.
For edible oil refinery industries, “water” is the main component for the process. The wastewater from oil processing industries contains both organic and inorganic content, which are produced after various processes like degumming, deacidification, deodorization and neutralization steps. The wastewater will be also highly acidic and oily with Sulphate and Phosphate content that cause serious threat to environment and mostly the aquatic life.
With the increasing demand on treating wastewater from edible oil processing units, membrane technology including ceramic membrane bioreactor and RO /NF combined process has been applied to treat edible oil processing wastewater.
