The wastewater volume generated by the maleic anhydride solvent method has decreased significantly

Thread Content

The wastewater generated in maleic anhydride production has a high COD, making it difficult to treat and resulting in high treatment costs. In actual production, practical methods have been developed to reduce the amount of wastewater generated, both from centrifuges and from cleaning processes, in a cost-effective manner. In particular, the amount of wastewater generated during centrifuge cleaning has decreased by over 80%, which leads to a significant reduction in the costs associated with wastewater treatment in maleic anhydride production. This approach is more effective than foreign cleaning methods and is better suited to China’s national conditions. The reduction in wastewater volume per cleaning cycle results in a direct benefit of around 20,000 yuan, based on the costs associated with wastewater treatment. Cost is objective! ! ! ! ! !
