Customer Case: Solid-Liquid Separation Project for Chemical Materials in Kazakhstan

This client is located in Kazakhstan and is engaged in the processing of chemical materials. They need to perform solid-liquid separation on aluminum-based soft materials containing acid. The material temperature ranges from 30 to 40 degrees Celsius, and the composition is 40% acid and 30% solid. There is no limit on the flow of solid materials. The client has high requirements for the corrosion resistance, sealing performance, and continuous operation capability of the equipment. Additionally, they hope that the equipment is easy to operate and has controllable maintenance costs.

The customer needs to purchase box-type filter presses for the filtration operation of corrosive materials. The specific requirements include:

• ✔ The equipment should operate stably under normal temperature and pressure conditions.
• ✔ The filter plates should be resistant to acid and alkali corrosion.
• ✔ The feeding system should be suitable for solid-containing materials.
• ✔ The pressing method should be automated to reduce manual operations.
• ✔ The drainage structure should be convenient for observation and collection of filtrate.

Based on the customer’s material characteristics and working conditions, we recommended a box-type filter press for them, model XMY20/700. The single unit configuration is as follows:

After the equipment was delivered, the customer used it for the solid-liquid separation operation of aluminum-based soft materials. The automatic hydraulic pressing system reduced the manual operation intensity, and the double clear flow structure made the filtrate discharge more smooth, facilitating on-site observation and collection. The PP filter plates have corrosion resistance, and the 304SS feed pipeline and the ultra-high molecular polyethylene slurry pump flow components operate stably under corrosive working conditions. The variable frequency motor drives the feed pump, which can adjust the feed speed according to the actual filtration situation, avoiding the impact on the filtration effect due to excessive feed speed. The configuration of the backup filter plates also reduced the downtime caused by filter plate replacement for the customer.
