Sealed liquid filter vessels are essential for liquid filtration. Liquid can only be filtered when there is some type of vessel or container. Liquid filter vessels can be found in hospitals, petroleum plants, factories, and any other place where bulk filtration of liquid is being done. The chemical manufacturing and fracking industries also use these large filter vessels.
Many factors need to be considered in order to choose the right filter vessel for the job. Flow rate of the liquid through the vessel is very important as it greatly effects sizing. For large flow rates, you typically use what is called a multi-round housing, which can have 20 bags or 100 cartridges, depending on what is being filtered. Connection size and type of piping coming in and out of the vessel, and what type of liquid you will be filtering will also determine which type of filter vessel to use.
