Industrial Water Filter – Its Types With Advantages and Disadvantages
Industrial Water Filter
An industrial water filter is of critical importance as each industry has its own specific and individual water treatment needs. The cardinal rule towards selecting an effective water filter is to design your system such that it has at least 10% more filter capacity. While installing an industrial water filter it is best to take the assistance of the manufacturer in designing the system. The manufacturers sometimes even do the water testing in order to determine the size of the filter best suited for your needs.
There are various industrial water filter options available in the market. It is important to select the correct filter type and size. Some of the options choosing the right industrial water filter are listed below:
The most popular industrial water filter is the Automatic Screen Filter. It is easy to install, is low maintenance with fast, high efficiency flush and low flush water volume. Its biggest advantage is that it can be installed in new as well as existing systems. Its fully automatic cycle does not interrupt the system flow during the flush cycle.
Gravity Effect Screen filters are quite easy to install. They are a low cost option and maintenance is easy. However, they require frequent periodic cleaning and a large footprint and have limited efficiency. They cannot be used above 200 microns or on pressure systems.
Bag and cartridge Filters are high efficiency filters that require a small footprint and interrupt with the work to the sub-micron level. But replacement cartridges are expensive and require frequent change outs. They range from medium to high cost Media(Sand) Filters are also a medium to high cost option. It provides effective filtration to 5 microns and is high on efficiency. But it requires periodic media changes and also a large footprint. Flush time can also be as high as 10 minutes in this system and it requires twin systems for uninterrupted operation Centrifugal Filters come at a low cost but are flow sensitive. They also cannot filter algae or particles below approximately 1.1specific gravity. However, their efficiency is high and they can operate continuously or in batches.
Tangential Screen Filters are again low cost and can be adapted to automatic operations. Its main disadvantage is its low efficiency flush, periodic screen removal and labor intensive pressure wash cleaning. Before you make a filter selection, it’s important that you do your ground work and find out about the various costs involved. This may range from equipment and installation cost, operating cost, maintenance cost, wastewater replacement to the exact level of filtration required.
