Seeking help with wastewater treatment
Thread Content
We are currently using the USAB process to treat acrylic acid wastewater. I don’t know how to calculate the dosage of chemicals to be added in the mixing tank – calcium hydroxide, magnesium hydroxide, iron salts, diammonium phosphate, and dipotassium hydrogen phosphate. I would like to ask what criteria are used to determine these dosages, what are the approximate range values, and whether there are any calculations or reference materials available on this topic
What kind of water are you dealing with? It’s so complicated; presumably the design has issues
For the kind of wastewater you mentioned, strict certification and calculations must have been carried out when implementing this wastewater treatment process; therefore, detailed information should be available in the original design documents or technical certification materials. Even other water treatment experts, despite having thorough knowledge of water treatment processes, are unable to provide practical guidance without knowing your specific wastewater parameters and conditions. Why don’t you ask the relevant department in your organization for the specific details? Unless your process design team was just trying to cut corners from the start.
Fertilizers such as diammonium phosphate and dipotassium hydrogen phosphate are added based on the actual conditions during the operation of the biochemical system; this is related to biological activity, and it determines whether a nitrogen source or phosphorus fertilizer is needed. The specific amounts to use can be determined by referring to information on microorganisms used in water treatment. It is recommended to look for electronic books on microorganisms online or to purchase some books. Calcium hydroxide, magnesium hydroxide, and iron salts are substances that should be used in the pre-treatment phase of biochemical processes, and there should be guidelines available regarding their use.
Our company can treat acrylic acid wastewater using special biochemical methods; there are proven cases of this approach abroad. No additional chemicals are needed, which simplifies the process and reduces operating costs. Feel free to contact us at QQ2426072427 for more information.
