**Case Study**
Jiangsu Low-Temperature Heat Pump Evaporator Cleaning Wastewater Case
**Project Overview**
The client is a high-tech enterprise specializing in providing high-end products and overall solutions for new energy commercial vehicle drive systems.
**Project Disposal Pain Points**
The client’s degreasing cleaning wastewater was originally outsourced for disposal at a cost of 3000 yuan per ton.
**WSD Environmental Solution**
In order to better achieve wastewater reduction and resource utilization, after a series of process comparisons, the client ultimately chose the WSD low-temperature heat pump evaporator. The equipment has a high degree of automation, reducing personnel operation; high concentration ratio, reducing outsourcing costs and saving costs; small footprint, reducing the area of the wastewater station; good water quality of the effluent.

**Disposal Effect**
After the WSD Environmental LT-2T low-temperature evaporator is put into use, more than 90% of the distilled water in the wastewater can be evaporated and reused, and the remaining concentrated liquid is outsourced for disposal.

**Comprehensive Benefits**
After the WSD Environmental 2T/D low-temperature evaporation system was put into operation at the end of 2021 to treat cutting fluid and degreasing wastewater, nearly 1.7 million yuan in disposal costs were saved annually.
