General introduction:

The wet processing workmanship for phosphoric acid production with the properties of the most mature technology, most economical method, which is the most popular workmanship for phosphoric acid production.
No matter the method of DH, HH-DH, DH-HH, or HH, for getting the clean phosphoric acid; get the high P2O5 collection rate, most factories will equip the vacuum filters with a vertical washing system to separate the phosphoric acid with the solid particles, the filters can be rubber belt vacuum filters, disc filters and pan filters, etc.
The filter system is one of the most complex construction and most expensive equipment for the phosphoric acid plants, how to get a higher working efficiency of the filters which is crucial for the phosphoric acid output, P2O5 collection rate, and quality, as the heart of the filters, the filter fabrics/filter belt playing a very import role of course.
When well understood the requirements of the phosphoric acid plants, accumulated abundant experiences in phosphoric acid production, as well as compared relevant filter fabrics in the market, Zonel Filtech developed a special filter fabric/filter belt for rubber belt vacuum filters in phosphoric acid applications.

Properties of the filter belt for phosphoric acid filtration usage:
1. The material of the filter belt is acid-resistant, stable, and strong in construction, with equal tensile strength and air permeability.
2. With a special S.S. clipper connection, the belt never broke from the joint part.
3. Good air permeability/water permeability, high filter efficiency, dryer the cake.
4.Smooth surface, easy to wash and regenerate, not easy to be blocked.
5. Easy installation and maintenance, durable.

Application:
For the solid and liquid separation when phosphoric acid production.
