Among the numerous applications of vacuum cloth filters in ecological systems, we can mention, in particular, those for the purification of waste water and for the recycling of raw materials such as phosphorus.
In Hamburg, for example, there is the world’s largest phosphorus recycling plant and uses our vacuum cloth filters to purify waste water.
Let’s find out more about it.
The characteristics of vacuum cloth filters for ecological systems
The vacuum cloth filters for ecological systems are designed to separate solids from liquids and are very useful in the presence of suspensions which, after discharge, make it necessary to wash the filtration cloth.
The general characteristics of our cloth filters are:
- Compact design
- High filtration speed
- Continuous operation
- High efficiency washing
- Presence of a partial or total hood
- Possibility of steam drying
- Construction in a wide range of sizes from 0.1m2 (pilot unit) up to 150m2
The functioning of vacuum cloth filters in ecological systems
The vacuum cloth filters inserted inside the ecological systems are ideal in the case of filtration processes that involve the presence of light solids.
In particular, we can supply this type of filter in various sizes based on the need for reduced filtration surfaces.
What distinguishes this type of filter is the presence of the cloth which adheres directly to the drainage grids and does not require other sliding supports.
When the cloth is moving, the filter is fed with the product.
While when the cloth is stopped, the liquid supply also stops.
In this way it is possible to apply vacuum and between the cloth and the filter and proceed with the separation of solids and liquids.
The fields of application of vacuum cloth filters for ecological systems
In the previous paragraphs we introduced our horizontal vacuum cloth filters and described their characteristics, now let’s focus on the application areas.
The vacuum cloth filters are ideal in application sectors that require reduced filtration surfaces and the presence of light solids.
In the city of Hamburg, for example, they use our cloth filters in a project for the recovery of phosphorus following the treatment of wastewater from rivers and refineries.
It is the world’s first large-scale plant for the recovery of phosphorus from sewage sludge ash.
Specifically, this recycling plant produces 7,000 tons of high purity phosphoric acid from approximately 20,000 tons of sewage sludge ash.
