Vessel Water Filter: Learn About This Important Water Filtration Equipment
Being in the water treatment installations industry for many years now, I can say that one of the mistakes people make is confusing vessel water filters with cartridge filters under the sink. However, it should be pointed out that this piece of equipment works at a totally different level compared to what people usually think.
What Is A Vessel Water Filter?
The term 'vessel water filter' implies a water filter pressure vessel made of fiberglass reinforced plastic or stainless steel. The filters are used to treat the water in order to filter out certain impurities such as sediment, chlorine, etc. The difference between this type of water filters and those used for home purposes is that they are not point-of-use filters.
Understanding the Process of Media Filtration
Water is filtered downwards inside the vessel using the layer of filtration media such as sand, carbon, or even resin. Each layer has different properties which enable the filter to remove different pollutants from water. For example, sand and gravel filter layers will contain the larger particles of sediments, whereas activated carbon will remove chlorine, odor, and organic components. In case water needs to be softened, then the resin layer in the vessel will replace calcium and magnesium minerals with sodium ions, providing softer water output.
The Importance of FRP Vessels in this Industry
FRP tank construction is used widely in most water filter units since they are more resistant to corrosion due to continuous contact with water and chemicals in some cases.
Backwash Cycle Process
With the passage of time, sediment and other materials become trapped in the media of the filtration system, causing decrease in flow and filtration. Backwashing is done to reverse the flow of water and flush out the accumulated material through the drain pipe. In most modern systems, this process is automated through programmable control valve, although manual backwash is more common in smaller residential systems.
Selection of Suitable Flow Rate Capacity
Flow rate capacity of the vessel water filter system helps decide if the filter system can sustain peak requirements without any pressure drops. It is especially relevant in commercial environments, where several water sources exist at the same time. If the vessel size is not enough, pressure drop occurs at times of high requirement.
Sediment Elimination and Water Purification
Apart from just filtering water, correctly dimensioned vessels enhance the water's overall quality by decreasing its turbidity, undesirable taste and odor that are characteristic of municipal water or well water. Sediment elimination prolongs the life of various downstream appliances, such as water heaters, dishwashers, etc., as without this cleaning process they would become clogged with sediment and minerals.
Useful Maintenance Suggestions
It is useful to pay close attention to the pressure gauges before and after the vessel, as any large pressure differential indicates clogged media and necessitates its backwash or replacement. Filtration media should be replaced according to manufacturer's instructions before it becomes inefficient, as it might start releasing contaminants.
Conclusion
The task of vessel water filter is not something that many expect, as they protect water quality within their homes and facilities. Knowing how to choose the right media, when to backwash, and how to size the right flow rates will give you an investment that provides you with quality water and nothing less.
