Does the treatment of high concentration COD wastewater always hit a wall? This MVR system helps you achieve compliance and reuse

Four steps to turn wastewater into treasure

1. Preprocessing should be done separately to reduce subsequent troubles
   Different types of wastewater should be treated separately:Acid alkali wastewaterAdjust the pH in the reaction tank, add chemicals for flocculation and sedimentation, and reprocess the supernatant after sludge pressure filtration;Chromium containing wastewaterDivided into two steps for reducing precipitation, first converting hexavalent chromium into trivalent chromium, and then precipitating and removing it. The sludge volume is reduced by 60% compared to traditional processes, and the subsequent treatment pressure is greatly reduced.
2. Membrane treatment "fine screening" can clear water and remove salt
   Pre treated water passes firstultrafiltration membraneIntercepting suspended solids and colloids, such asEmulsion wastewaterEven the tiny oil droplets inside can be stopped; Once againreverse osmosis membraneMore than 90% of the salt and heavy metals can be removed, and the resulting water is clean enough to be directly reused for cleaning and cooling on the production line, without the need to buy new water.
3. MVR evaporation "concentration", the concentrated liquid becomes residue
   The concentrated water generated by membrane treatment is handed over toMVR evaporator(Vacuum distillation system). It can evaporate water in a low-pressure vacuum environment without the need for high temperature, leaving behind a concentrated solution that can then be fed backSteam scraper dryerIt becomes a residue with a moisture content of only 5% -10%, and the volume of hazardous waste is directly reduced to 10% of its original value, saving more than half of the disposal cost. What's even more impressive is that it can recover steam heat to preheat new water, with energy consumption 40% lower than traditional evaporators, making it particularly suitableHigh concentration wastewaterhandle.
4. Steam scraper "finishing", fully automated without worrying
   The dryer comes with intelligent cleaning and defoaming functions, even for processingoily wastewaterNot afraid of obstruction; The entire system is controlled by PLC, from water inlet to outlet, from dosing to slag discharge, without the need for manual monitoring. The workshop master said, "In the past, we monitored dosing in three shifts, but now we only need to check the data once a month

The benefits of using it are tangible and visible

• 水真能回用The treated water reuse rate exceeds 90%, and Wuxi Geely Automobile processes 600 tons annuallyCutting fluid wastewaterAfter reuse, the new water fee has been reduced by 30%;

• Significant reduction of hazardous wasteShenyang BMW ProcessingCleaning agent wastewaterAfter MVR evaporation of the concentrated liquid, the amount of hazardous waste is reduced from 2 tons per day to 0.2 tons, saving one set of equipment costs per year for disposal;

• Compliant and stableThe discharge water standard is much lower than the national standard for aviation manufacturingChromium containing wastewaterAfter processing, the chromium content is reduced to below 0.05mg/L, and there is no need to panic in environmental inspections anymore;

• strong adaptabilityModular design, whether it is a large factory processing 50 tons per day or a workshop with small batches and multiple varieties, can be flexibly adjusted. When expanding production, simply add modules directly.
