1) Stable effluent quality: MBR uses membrane separation technology to achieve efficient solid-liquid separation. The effluent suspended solids content is less than 10 mg/L, and the turbidity is less than 1 NTU. The water quality is clear and transparent and can be directly reused in industrial cooling water and other
MBR Process OverviewConventional Activated Sludge (CAS) is widely used in various sewage treatments. Since gravity sedimentation is used as a means of solid-liquid separation, it brings many problems, such as low solid-liquid separation efficiency, low volume load of treatment equipment, large floor space, unstable effluent quality, low oxygen transfer efficiency,
2. Classification of electroplating wastewater based on pollutant composition and process linksIt can be mainly divided into three categories. 1). Chromium-containing wastewater: mainly hexavalent chromium (Cr⁶⁺), which is highly toxic and carcinogenic. It needs to be converted into low-toxic trivalent chromium (Cr³⁺) through chemical reduction (such as sodium sulfite), and
