The process of filtering water involves removing pollutants from a starting point of raw water. In order to supply water of the proper quality, water purification systems and water filters are set up in the production line.
Membranes are used to catch and eliminate contaminants as the water moves through the system. There are numerous types of water filters and water purification systems used, which include main 4 types as given below:
There are numerous options, including;
· Reverse Osmosis
· UV rays
Let’s discuss these in detail:
1: UV or Ultraviolet rays
In order to prevent bacterial growth and replication, a UV light is used. They have a brief normal life and are hence harmless. pH, taste, or color are unaffected by UV.
Chlorine, chloramines, ozone, bromine, and a wide range of organic pollutants, can all be removed with UV treatment.
2: Reverse Osmosis
A reverse osmosis system uses raw water that is passed through a semi-permeable membrane, to remove pollutants and produce pure water. Reverse osmosis is becoming more and more well-liked because of all the advantages it offers, and since it is a green method of treating commercial and industrial water.
There are no chemicals needed, replacing membrane components is less expensive, and operator involvement is limited. Since, a reverse osmosis system is an automated one, it self-cleans. It simply has to be checked once a day by staff members on site. The price of membrane components decreases, as membrane solutions become more and more prevalent.
Reverse osmosis is commonly utilized in the design of pure water systems, since it can reject 99.9% of microorganisms.
What types of water filters are used in industries?
· Deep bed filters
The kind of impurities to be eliminated will determine the materials utilized, in a deep bed filter. In order to filter materials of various sizes and produce a pressure drop across the filter, filter media are often stacked.
To hold the larger particles in place at first, the grains are larger. The filter medium's size is then decreased to hold smaller particles in the intermediate phase, and the final layer is a gravel medium, which supports the filter medium and distributes the water, so that it leaves through distributors or nozzles.
The collector or distributor, which holds the filter media and stops it from leaving with the waterflow, is where clean water or product leaves the system.
· Cartridge Filters
The body of the cartridge is made of pressed polyethylene fibers or as a fabric, one of the most cost-effective filter media, although, it has a very limited lifespan.
The medium traps pollutants while discharging pure water. When compared to deep bed filters, water filter cartridges are relatively less expensive, and have a significantly higher filtration effectiveness.
· Bag Filters
Although, it could have a little better water flow, and if we apply pressure, good results may be produced. Using these filters is equivalent to using cartridge filters. The fibrous material used in the filters allows water to pass through, while trapping suspended and solid particles.
These filters are less expensive than alternative techniques, appropriate for a wide range of applications, and sometimes a good fit for certain processes. Similar to cartridge filters, they require routine replacement and attention to pressure variations.
· Disc Filters
They were initially developed to filter drip irrigation water for use in agriculture, but the same idea works just as well in the workplace.
Because, of these systems advanced technology, we can clean deep-bed systems with less water and faster. They are modular systems that can expand by including more filters, when a higher flow is required.
