Wastewater from sulfur exhaust gas alkali scrubber tower
Thread Content
May I ask how everyone handles the wastewater from the alkali scrubber towers for sulfur-containing exhaust gases?
The treatment of wastewater from sulfur exhaust gas alkali scrubbing towers can be carried out using the following methods: 1. Biological treatment: The wastewater is sent to a biological tank for degradation, with active microorganisms being used to break down the organic substances in the wastewater. 2. Chemical method: The sulfates, sulfites, and other ions in the wastewater are converted into calcium sulfate, and then the suspended solids are removed through processes such as precipitation and filtration to achieve purification. 3. Membrane separation method: The wastewater passes through a membrane separation device, allowing the solutes to pass through the semipermeable membrane while the solvent remains on one side of the membrane, thereby achieving separation and concentration. 4. Efficient precipitation method: The wastewater is mixed with chemicals to initiate a reaction; subsequently, rapid rotation or compressed air is used to form tiny particles in a short time, which are then removed through precipitation. All of the above methods can be used to treat the wastewater from sulfur exhaust gas alkaline scrubbers; the specific method to be chosen should be determined through evaluation based on actual conditions. .

Hello! May I ask if your sulfur exhaust gas alkali scrubber is located before or after the exhaust gas incinerator?
