Case study of a metal products company in Foshan

The business scope of the enterprise includes production, processing and sales of: hardware products, mechanical equipment and accessories, lighting appliances, and electronic products.
Wastewater type:Machining emulsion wastewater
There is a problem:Production-oriented enterprises need to make more scientific improvements in terms of environmental protection, and the cost of outsourcing the emulsion treatment is relatively high
Our plan:Pretreatment + BL-4T low temperature evaporation system + silicon carbide ceramic membrane, after the wastewater is treated, 95% of the distilled water is returned to the production line for recycling
case analysis:The customer unit produces 3 tons of wastewater per month, and the treatment cost is 6,000 yuan/ton. The annual outsourcing treatment cost is about 210,000 yuan. The post-treatment cost of applying pretreatment + low-temperature evaporation equipment + silicon carbide ceramic membrane has changed from the original 6,000/ton to 8,000/ton tons, the concentration ratio reaches 95%, the customer's annual water volume is 36 tons, the annual waste water outsourcing treatment cost is saved by 200,000 yuan, and the waste water discharge is reduced by 95%
