The industrial water filtration system helps in various separation and purification needs. They may range from compact, and simple to complex and multi-unit processes and serves lots of applications. If you are new in water filtration, then you might be asking about "What is Industrial water filtration systems and its working."

What is Industrial Water Filter?

Industrial Water Filter

An industrial water filter is a device that helps in removing any unwanted material from the liquid used in many industrial applications.

Some of these materials are:

  • Metals
  • Sediments
  • Minerals
  • Odor
  • Chemicals
  • Other impurities

Industrial Water Filters‘s Function

The main function of any industrial water filters is to shield human health and various sensitive components in industrial applications.

Types of Water Filtration Systems

There are various types of water treatment systems. Some of them are given below:

  • Raw water treatment systems
  • Boiler feed-water treatment systems
  • Cooling tower water treatment systems
  • Wastewater treatment systems

The Process of Raw Water Filtration

Raw water is usually untreated and unpurified. It must undergo various treatment and filtration steps to make it safe for industrial use as well as consumption.

Raw material comes from many sources such as:

  • Groundwater
  • Bodies of water
  • Rainwater

By treating the raw water not only make the water safe for human consumption or contact but also removes all kind of impurities and pathogens that is not good for human. It also preserves overall facility’ systems.

For instance, Softening hard water may remove chemicals such as magnesium and calcium. If it doesn’t remove then they built up pipe joints.

Each filtration system comes with a different process and is customized with unique requirements and demands. Most of the system allows the 5-basic step to filter water as well as make it safe to use.

  1. Intake
  2. Clarification
  3. Disinfection
  4. Ion exchange
  5. Distribution

We discuss them one by one:

  • Intake

First of all, raw or untreated water is brings into the water filtration process. It uses both pumps and gravity to draw water into the system. The intake system has a grate that can easily block objects and take them into the system.

  • Clarification

To remove any kind of hard of solid particles from raw water, it is further sent to the clarification process. Clarification involves many stages such as Coagulation. In coagulation adds some chemicals and adjusts the PH level of water by making solid clumps for more lenient filtration.

  • Disinfection

In this stage, the water is further treated for biological contaminants. Every stage of the system needs to remove toxins and pathogens from water. It is the best way to make water sufficient for consumption.

Some of the possible disinfection methods that used are:

  • Membrane-based filtration
  • UV heat, and other physical disinfectant methods
  • Chlorine and other chemical disinfectants

The membrane filtration method is the method that is used at the later stage of the filtration cycle. It generally uses ultra-filtration, Nano-filtration, and micro-filtration to filter water easily.

  • Ion Exchange (IX)

The Ion exchange units can easily soften water as well as offer many specialized and perfect treatment methods. To soft hard water, the Ion-exchange IX unit sends the water streams via acid-cation resin. This resin is further charged with sodium elements that let to captured magnesium and calcium.

  • Distribution

The distribution system of the water filtration system routes the water to the facility system. It further helps to make water suitable for manufacturing use and consumption for disposal.

Working process of Industrial Water Filters

Industrial water filters also are known as surface filters that can easily strain water via the membrane. They can also be known as depth filters that have porous materials used for collecting impurities through the medium.

The depth filters are the common filter used in the industrial water filtration system because they come with greater capacity for dirt retention. Two types of depth filters are used named cartridge and deep bed depth filters.

Deep bed depth Filters Vs. Cartridge Filters

Deep Bed Filters

The choice of constructing material used in deep bed filters depends on the containment type you want to remove instantly.

We can also use various materials that are placed in layers and filter out any impurities. At the start of the process, the dust particles are stick to the clean filters. After that in the transient phase, the dust particles are stick on the filter are deposited on the media that can be covered by the filtered particles.

The filtration layer is stirred mechanically which allows proper water circulation via media so that it removes dirt particles.

Clean water usually comes out with the help of a backwash screen that can permit the water to pass through filter media.

Cartridge Filter

The filter media consists of a single material that is wound all-around plastic and metallic frame. The frame may somehow are perforated in many cases. The medium is usually restrained dust particles and impurities. It also released pure clean water with the help of outlets. So, due to this reason, the dirty and impure water passes through outlets.

These filters are low in the budget as compared to other types. It can offer a better level of filtration efficiency.
