Treatment of high-concentration sodium chloride wastewater
Thread Content
Hello, fellow sea lovers! I’m facing a problem with wastewater treatment. Our factory generates 150–200 m3 of saline wastewater per day, with a sodium chloride concentration of 80 g/L and an ammonium chloride concentration of 10 g/L; the pH level is between 7 and 8. Environmental regulations require zero discharge of such wastewater. There are two options now: multi-effect evaporation and mechanical atomization evaporation. Which method is the most cost-effective? Thank you!
MVR is indeed cheaper than both of these alternatives. It’s just the noise and routine maintenance that are annoying.
For mechanical atomization evaporation, it depends on whether you are in an area like the northwest with plenty of sunlight; additionally, you need to consider whether there are any organic substances present, as well as whether the mist released into the air will have an unpleasant odor or not； For multi-effect evaporation, what is your steam price? What’s the electricity price? In comparison, MVR still has advantages
MVR is currently the most energy-efficient and cost-effective method for wastewater evaporation crystallization. The initial investment is high, but depending on the price of steam in your area, and considering the volume of evaporation required, the amount of steam used in the Jiangsu and Zhejiang regions over two years is roughly equivalent to the initial investment.
