OS filter (continuous vacuum rotating filter)
Our OS filter (continuous vacuum rotating filter) is a cylindrical single-chamber filter made by improving the multi-chamber Oliver filter, and was developed with the aim of commercializing a simpler and lower cost model than the Young filter, in which the cylinder is divided into many sections.
It is a continuous vacuum rotating filter that reduces pressure while rotating a single-chamber filtration drum at low speed and that filtration takes place on the external surface of the drum.
Standard type
This type performs filtration and dehydration on the external surface of the drum, and scrapes any attached cake off with a scraper.
Precoat type
Filtration commences after a filter auxiliary agent layer is provided. The precoat layer is continuously scraped little by little with a special auto scraper attached to the surface of the auxiliary agent , and the cake remains attached to a clean filtration surface. This type is suitable for filtration of materials difficult to filter, and has the same structure as the general type except for the scraper.
Applications
Chemical, Food, Paper, Pharmaceutical, Metal smelting, Inorganic chemical, Environment(wastewater treatment), New energy, General chemical engineering.
Advantage
- 1Pressure loss is smaller than that with the multi-chamber type Oliver filter, and therefore, capacity per unit area is larger.
- 2No automatic switching valve, such as an automatic valve, is required.
- 3A simple fixing method with no unevenness or slack in the filter fabric makes the filter fabric a longer service life.
Test machine
We have a test machine system with a filtration area of 0.1m2, and have a consultation service available to users.
