What are the physical treatment methods for pharmaceutical wastewater?

Based on the characteristics of pharmaceutical wastewater, physicochemical treatment is required as a pretreatment or post-treatment step in its treatment process. Currently used physicochemical treatment methods mainly include coagulation, flotation, adsorption, ammonia stripping, electrolysis, ion exchange, and membrane separation. (1) Flotation Method: Flotation methods typically include various forms such as

How to effectively treat drinking water?

1. Drinking water treatment generally involves purification, chlorination, and sometimes the addition of fluoridation agents. Treated water is collected by gravity or pumping into reservoirs and distributed through water towers or surface facilities. After use, the wastewater is typically discharged into the sewer system and treated at sewage treatment plants

Why choose MBR to treat wastewater?

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

What are the methods for reducing COD through deep sewage treatment?

It is necessary to select an appropriate combination of technologies based on the water quality characteristics. The following are common and efficient methods: 1. Chemical oxidation method ‌ 1.1 Fenton oxidation‌: Utilizes the reaction of Fe²⁺ with H₂O₂ to generate hydroxyl radicals (·OH), which can efficiently degrade refractory organic matter
