What is Bag filter housing and its types?
In both commercial and industrial uses, bag filters remove anything from sediment to other solids to some forms of liquid from the water. Bag filter systems are a popular choice for water filtering because of its large holding capacity, high flow rate, and ease of replacement. A bag filter is a filtration material bag in a filter housing, as the name implies. Bag filtration systems are low-maintenance devices that are both efficient and reliable.
Bag filter systems work on a straightforward concept. Between the bag filter and the housing, a tight barrier is produced, preventing pollutants or unfiltered water from escaping. Only filtered water can pass through, leaving everything else in the filter bag.Each bag is designed with specific materials for strength but does not enable pollution or other dangerous particles to get through.
Types of bag filters
1: Duoline/Moduline Bag Filter Housings: Duoline filter housings are used in situations when the system flow cannot be stopped to change the filter bag. To reroute the flow between the two housings so that the isolated, out of service housing may be serviced, a butterfly or ball valve assembly is employed. The flow is never interrupted. For situations where the flow rate is too high for a single bag filter housing, modular filter housings are used.
2: Ecoline Bag Filter Housings: Filter housings of high quality and low cost for applications up to 100 psi. Even if the application does not require stainless steel right now, one can still benefit from its higher corrosion resistance with consistent performance over time. The Ecoline saves money on running costs thanks to its simple, easy-to-use V-Clamp closure, which allows for quick bag changes.
3: Maxiline Bag Filter Housings:The cover on the Maxiline VMBF SE cannot be opened until the vessel has been thoroughly ventilated. A hand wheel operates a threaded spindle system that opens the clamp, allowing the cover to be raised with the help of a spring assisted hinge. When opposed to the 10 Min or more it requires to open a vessel with a bolted closure, the entire process takes less than 30 seconds. The Qic-Lock clamp must be fully closed as well as the safety interlock engaged, which locks the vent valve, before the vessel may be re-pressurized.
4: Miniline Bag Filter Housings: Miniline vessels are designed to be installed on their own. Stainless steel construction ensures years of reliable, precise filtration without the risk of corrosion, and at a cost that is competitive with carbon steel. Miniline vessels come in two series: EBF for low-pressure applications and SBF for high-pressure applications.
5: Maxiline Multiple Bag Filter Housings: For applications requiring high flow rates and quick bag change out, the Maxiline MBF HD filter vessels contain up to 24 filter bags. Maxiline MBF HD filter vessels can withstand up to 4500 GPM and have no exterior leakage assurance.
6: Polyline Bag Filter Housing:These all-plastic housings will take most standard 7′′ diameter filter bags for application versatility. This enables the vessel to be used with a wide range of filter bags to meet the specific needs of the application. Users are not limited to just a few "non-standard" size filter bags when using a PVC or CPVC bag filter vessel.
7: Polypropyline PVDF Bag Filter Housing: This one-piece moulded body is easy to clean and has no seams, welds, or crevices to collect dust. The cover is hand-removable and includes a built-in vent valve made of all-plastic with an inbuilt 1/4′′ gauge tap. The two bottom pipe connections can be used as an outlet or drain, allowing for simple in-line or loop plumbing arrangements with no modifications to support any installation design. The PPL and PVDF Vessel range is the finest solution for contamination-sensitive or strongly corrosive filtration applications.
