1 Advantages of filter materials: according to the particle size distribution, titanium based filter elements with appropriate filtration accuracy are selected to ensure the quality of filter solution and prevent products from penetrating into the filter solution, resulting in waste of resources; In addition, the filter element has long service life and high corrosion resistance. The filtrate has low content of heavy metals and little environmental pollution.

2 Structural design optimization: the structure of StarOne thickener has been optimized in many aspects, such as mixing, filter element sealing structure, equipment cylinder layout structure, shell internals and filter element layout, peripheral pipeline piping, etc. It has better performance, less floor space, and is convenient for replacement and maintenance. The clearing module and filter module are all of modular design, which are processed in the factory with small on-site installation workload. The processing in the factory is conducive to the implementation and management of the quality system.

3 Regeneration and upgrading of membrane cleaning: Online recoil is divided into two recoil modes: gas and liquid. The recoil mode can be flexibly selected according to the characteristics of materials, and the recoil effect is good.

4 Electric instrument control: high precision instruments are used to ensure the accuracy of process parameters, bus layout is used for flexible local / remote dual control operation, and pneumatic actuators are used for sensitive, safe and reliable action; It is equipped with visual human-computer interaction interface, one key start and stop function and full-automatic process control, making the operation easier.
