Water filtration is the procedure of removing unwanted chemicals, suspended solids, biological contaminants, gasses, etc. from water. The primary aim of water filtration is to make water fit for a specific purpose.
The use of the right water filtration system enables users to accomplish the water filtration task. The process of water filtration is applied in various domains, whether it is domestic scale or industrial.
Water filtration methods help in reducing the concentration of particulate matter including bacteria, parasites, viruses, suspended particles, algae and fungi. They also contribute in decreasing a range of concentrated particulate matter.

Reverse Osmosis Water Filtration
Reverse osmosis is a high-efficiency process where water pressure is applied to push water via a semipermeable membrane. When the water membrane is forced against the surface of the membrane, the dissolved particles are pushed off. 
Simultaneously, purified water is formed on the other side as the water molecules are diffused through membrane molecule by molecule. It is one of the popular methods of removing contaminants from water.
In a reverse osmosis system, the quality of membranes plays a key role in improving filtration performance. Get in touch with the best water filtration systems supplier in Dubai/UAE to find high-quality RO membranes.
How does a Reverse Osmosis System Work?
A reverse osmosis filtration system is a chemical-free and economical solution to enhance the odor and taste of drinking water. With the help of RO systems, users are able to produce clean and filtered water by forcing tap or brackish water through a semipermeable membrane.
The filtered water from a RO system is directed towards the storage tank, whereas, the impurities that are eliminated from the water molecules are released out the drain. Both pre and post filters are included in the reverse osmosis system that enables operators to remove contaminants in an additional way.
The process of reverse osmosis is able to remove up to 99% of dissolved ions, colloids, particles, bacteria, organics, and pyrogens from the feed water. Based on the contaminants’ size and charge, the reverse osmosis membranes are able to remove them.
This is why domestic water treatment water filtration system utilize this method.
Ultraviolet Water Filtration & Sterilization
The UV spectrum from sunlight is primarily utilized for the Ultraviolet Water Filtration method. The UV in use is at much low intensities so as to carry out safe filtration procedures.
UV Water Filtration’s main aim is to kill the microorganisms and for this a frequency of  254 nanometers (nm) is used. The UV lamp that is used in this type of filtration system is specifically designed to have the highest rate of UV energy at this frequency.
Benefits Of Using Ultraviolet Water Filtration & Sterilization
Some of the ultimate benefits of using this filtration method are -

  •  It is a natural way of water purification. The key technology applied in this method is the UV spectrum of sunlight which is a natural purifying process.
  • There is no formation of toxic and harmful by-products during the UV filtration and sterilization process. Hence, it is an environmentally-friendly filtration procedure to be used.
  •  It is one of the cheapest filtration/disinfection systems available with its low operating costs involved.
  • In terms of eliminating microorganisms from water, this method of filtration is highly effective.
  • The filtration method requires no chemicals to be added during the process which means it has no risk of overdose. Hence, it is an overall safe filtration method to use.
  • This is an in-contact water purification method which means it is a rapid method to be used.
  • There are many advanced UV filtration systems available that come with high-end features such as precise UV intensity monitors, computational fluid dynamics (CFDs), etc. Therefore, making the UV filtration method easy to manage.

UV Filtration is a safe water filtration system water treatment method that is capable of destroying up to 99.99% of disease-causing microorganisms, includes -
•    E. coli
•    Cholera
•    Salmonella
•    Giardia
•    Coliform bacteria
•    Cryptosporidium
•    Viruses and more
Sediment Filtration
Sediment filtration method is mainly used in well water applications and is also seen to be used in municipal water systems. The filters used in this method acts as a barrier against unwanted particulates and grits that can obstruct the water filtration systems.
However, this type of filtration is not much effective in killing microorganisms on an individual scale hence is combined with UV filtration systems generally. Sediment filtration in UV systems works in reducing the efficacy by hindering the UV light’s ability to reach the waterborne microbes.
Sediment filtration helps majorly in expanding the life-span of water appliances.

The choice of filtration method needs to be selected carefully to ensure optimized performance of the filtration system. As domestic water sources are subjected to contamination, the appropriate water treatment solution comes handy in removing the disease causing agents.
The filtration methods mentioned in this blog are some of the common solutions used in domestic scale water filtration system applications.
