Filter press helps the chlor-alkali industry achieve healthy and sustainable development

As a by-product waste of caustic soda plant, salt sludge is generally disposed of by landfill, which is not only harmful to the environment, but also wastes a lot of barium sulfate resources. Around the 1970s, many countries have done a lot of research work on mercury recovery and treatment technology in salt sludge. The chlor-alkali salt sludge filter press has become an essential solid-liquid separation equipment in the chlor-alkali industry. According to estimates, the environmental protection field is currently the largest demand market for filter press products in my country, with a demand accounting for close to 45%; followed by the chemical industry, with a demand accounting for 19.7%. As a result, the chlor-alkali salt mud filter press technology helps the chlor-alkali industry achieve healthy and sustainable development.


Sudong Chemical's chlor-alkali salt mud filter press is an intermittent operation. The filter plate has stable performance, convenient operation, safety, and labor saving. The metal and plastic steel filter plate is precision casted, resistant to high temperature, high pressure, and durable. This is a good treatment for the chlor-alkali industrial salt sludge. After the filtrate is left standing, it will be sent to the salt chemical section for recycling, and the filter cake is buried deep in the ground. In this way, the pollution of salt mud is solved.


Commonly used chlor-alkali salt mud filter press type:

1. The filter press for chlor-alkali has manual compression, mechanical compression and hydraulic compression.

2. The operating system has automatic, semi-automatic, PLC program control, DCS remote control and HMI man-machine interface operation;

3. There are clear currents and undercurrents in solid-liquid separation; it can be filtered, washed, squeezed, and the filtration pressure is 0.2-2.0MPa.


In short, healthy and sustainable development is the primary problem to be solved by chlor-alkali industrial enterprises. Among all kinds of environmental protection equipment, chlor-alkali salt mud filter press has its advantages in chemical applications. The salt mud processed by the filter press in the chlor-alkali industry is successfully used to prepare adsorbents, snow melting agents, and produce building materials, agricultural fertilizers, and high-strength Lightweight ceramsite, etc., turn waste into treasure and achieve harmless treatment. The chlor-alkali salt mud filter press helps the chlor-alkali industry to achieve healthy and sustainable development.
