Treatment and recycling of organic wastewater
Thread Content
We produce a range of adsorption resins with excellent adsorption properties, and these resins can be reused. They have already been used by many companies in practical applications; if you are interested, feel free to contact me. Resins from this series can be used for wastewater treatment and organic matter recovery, as well as to reduce COD. Last edited by chaochao on 2008-11-6 at 11:12.]
I’m glad to see my colleagues; I am also engaged in research on the application of adsorption and exchange resins. In China, I have participated in over 30 large-scale application projects, and I have developed more than 20 research projects. Adsorption and exchange resins have indeed achieved excellent results in certain fields, but at present, there are still some shortcomings. First, the water quality requirements are quite high. Pre-treatment of wastewater is quite important; otherwise, after being used for a period of time, the resin is likely to become poisoned and lose or reduce its effectiveness. Second, desorption conditions. Currently, the desorption methods used for resins in applications are mainly acid/base/solvent-based desorption. In the field of wastewater applications, organic solvents can basically be ruled out, as using organic solvents for regeneration leads to increased losses due to resin residues and water dissolution, thereby raising operating costs. Moreover, residual solvents in water cause an increase in CODcr, imposing a burden on subsequent treatment processes. Third, and so on. There are other application scenarios and precautions; let’s discuss them in detail over a call
Are there any colleagues from NanDa GeDe Environmental Protection Company? !
In applications for wastewater treatment with high salt content and organic matter levels (such as salt content of 3000 mg/L, COD of 200 mg/L, etc.), it is unknown how long the regeneration time will be Is the polarity reversed frequently? Service life? Energy consumption per ton of water produced, operating costs?
