Is it difficult to treat wastewater from power batteries? This MVR membrane filtration equipment helps you achieve standards and reuse

First, let's talk about how difficult it is to deal with these wastewater. Have you also been hit?

• Wastewater from electrode material preparationThere are many heavy metals and mixed components, and the traditional sedimentation method has a large amount of sludge, which can also easily cause waste of resources such as lithium and cobalt;

• Coating wastewaterNMP and PVDF binders make wastewater "sticky and toxic", difficult to degrade in biochemical treatment, and outsourcing disposal costs are even more expensive than gold;

• Chemical/fractionation wastewaterLithium salts and organic carbonates in electrolytes, even in trace amounts, can affect emission standards, and a slight lack of attention can lead to crossing the environmental red line;

• Workshop flushing wastewaterMix some electrode powder today and bring some oil stains on the ground tomorrow. The water quality fluctuates greatly and ordinary equipment cannot withstand it;

• What's even more troublesome is that when expanding production, the water volume doubles, and the treatment efficiency of old equipment cannot keep up, watching helplessly as the production capacity is stuck in the wastewater process.

How did this device break through? Dual use of "evaporation+membrane filtration" to treat complex wastewater

Step 1: MVR negative pressure distillation to "concentrate" the wastewater

• Corrosion resistant and manufacturing resistantThe core vacuum Roots pump uses stainless steel rotors and nickel plated shells, whether it isWastewater from electrode material preparationIs it a strong chelating agent or notCoating wastewaterOrganic solvents cannot harm it, and there is no need to worry about equipment corrosion even after long-term use;

• Energy savingThe waste heat from steam and distilled liquid will be recovered to preheat the incoming wastewater and treat 1 tonChemical/fractionation wastewaterThe energy consumption of the evaporator is 50% lower than that of traditional evaporators, which can save one set of equipment money in one year's electricity bill;

• auto-runThe entire process of heating, evaporation, and cleaning is automated, eliminating the need for workers to monitor and adjust parametersWorkshop flushing wastewaterThe water quality suddenly changes, and the integrated dual channel cooling system can also stabilize the steam temperature, ensuring a stable treatment effect.

Step 2: German imported ceramic membrane filtration to make the water "clean enough for reuse"

• fine filtration0.1 nanometer level cross flow filtration technology, capable of blockingCoating wastewaterResidual trace NMPAssembly wastewaterThe cleaning agent contains small molecules that do not even allow bacteria and colloids to escape. The filtered water is clear enough to be directly reused in the workshop cleaning process, reducing the cost of new water by 30%;

• Anti pollution and durableCeramic film is resistant to acid and alkali, high temperature, even ifWastewater from electrode material preparationNo matter how many heavy metal ions are inside, they will not block the membrane pores. The built-in automatic backwash function can restore filtration efficiency by cleaning once every 15 days. The filter element can be used for more than 2 years without frequent replacement of consumables;

• resource recyclingLithium, cobalt and other metals in the concentrated solution can be further recovered, turning waste into treasure, reducing the amount of hazardous waste disposal and creating additional income.

The benefits of using it are praised by peers: worry free, cost-effective, and compliant

• Environmentally friendly and stableAfter treatment, the COD of the effluent is less than 50mg/L, and the concentration of heavy metals is much lower than the national standardCoating wastewaterNMP orElectrode material wastewaterBoth nickel and cobalt can meet emission standards, so there is no need to panic about environmental inspections anymore;

• Reduce costs by halfMVR's waste heat recovery reduces operating electricity costs by half, and the long lifespan of ceramic membranes reduces consumables expenses,Workshop flushing wastewaterThe processing cost has significantly decreased, and modules can be directly added during production expansion without the need for repeated investment;

• strong adaptabilityWhether it is a small workshop that processes 10 tons per day or a large factory that processes 100 tons per day, modular design can be flexibly adapted,Assembly wastewater、Waste gas treatment wastewaterThese low concentration waters can also be efficiently treated, and one system can be used multiple times.
