Filter presses are a type of filtration system used to separate solids from liquids. A chamber filter press uses a series of plate assemblies that contain filter cloths and form chambers where the separation takes place. They are commonly used for dewatering sludges and pastes in various industrial processes. If you are considering buying a chamber filter press for your application, here are some key things to understand.
How Do Chamber Filter Presses Work?
A chamber filter press consists of alternate plates containing filter cloths and spacing plates that separate the filter chambers. As fluid enters the plate assembly under pressure, the solids are trapped on the filter cloth while the liquid passes through.
When the press is closed, the plate assembly is compressed forming separate wedge shaped filter chambers between the filter and spacing plates. Fluid is then fed into these chambers where the separation occurs.
The compressed chambers ensure a high solids capturing rate while the liquid is forced through the filter cloth into drain channels built into the spacing plates. Drainage valves then allow the filtered liquid to exit the system.
Types Of Chamber Filter Presses
There are two main types of chamber filter presses:
•Continuous Presses – Fluid continuously enters and exits the press while the plates remain stationary. They are used when a constant supply of feed material is available.
•Batch Presses – The plates in batch presses move to expose new filter areas.They are used for intermittent or periodic filtration where feed material must be stored first.
Advantages Of Chamber Filter Presses
•High throughput rate and separation efficiency. They can filter large volumes of fluid quickly.
•Produce both cake and filterate simultaneously, speeding up dewatering.
•Simple design with few moving parts, resulting in reliable operation and low maintenance costs.
•Can handle a wide range of feed materials, both acidic and alkaline.
•Produce filter cakes with lower moisture content than other methods.
•Compact footprint, suitable for space-constrained areas.
Typical Applications Of Filter Presses Chamber Type
Chamber filter presses find wide application across industries for efficiently dewatering and separating various slurries and pastes. Examples include:
•Mining – Dewatering mineral slurries produced during metal extraction and purification.
•Chemical – Recovering valuable solids from waste streams and byproduct liquids.
•Food Processing – Removing moisture from fruit and vegetable pulps during processing.
•Wastewater Treatment – Concentrating sludges from municipal and industrial wastewater.
•Pharmaceuticals – Isolating precipitates during drug production.
Factors To Consider When Buying
When shopping for a chamber filter press, there are several factors to evaluate based on your application requirements:
•Feed material type – Particle size, acid/base levels and other properties
•Throughput capacity – Amount of fluid to process per hour
•Required solid/liquid separation – Final specifications for cake dryness and filtrate clarity
•Plate material – Stainless steel or other alloy suitable for your chemical process
•Required operating pressures – Higher pressures yield drier filter cakes
•Temperature range – Ability to handle hot or cold feeds
•Automation options – PLC controls, process monitoring sensors, etc.
•Compliance – Meet certification standards for your industry
•Service and support – Manufacturer reputation,spare parts availability, warranty etc.
