How is wastewater from ordinary workshops classified and treated?
Thread Content
What are some good classification methods? For example, in our workshop we have categories such as high concentration and high salt content, low concentration and high salt content – what is the basis for these classifications? Thank you
Generally, it’s processed together after mixing. If different streams are handled separately, how many devices would that require?
Everything at our company is handled together
There are many methods depending on the type of wastewater
There are many types of wastewater in workshops: saline wastewater, oily wastewater, sulfur-containing wastewater, condensate water, drum wastewater, etc., which need to be treated separately.
This is a question that is difficult to explain in just a few words, as it involves various fundamental theories from physics and chemical engineering. A specific analysis must be conducted based on the properties of the particular wastewater. It can be treated separately, combined, or through mutual treatment methods such as acid-base neutralization. There are also physical treatment methods, including filtration, sedimentation (separation of liquid from solid), and decantation (separation of oil from water), among others ； There are also chemical treatments ； There is also biochemical treatment. I hope you will carry out thorough and meticulous foundational work to ensure the proper treatment of various types of wastewater.
Classified by treatment method. For high COD levels, biochemical treatment is required; if the pH is not appropriate, it needs to be adjusted; and in cases of high salt content, centrifugation or pressure filtration is used. Items that can be processed in the same way should be processed together.
