Industrial water filtration is a process that removes impurities from water before it is used in manufacturing processes. This article discusses the steps in industrial water filtration, the importance of the process, and the different uses for filtered water.

Industrial Water Filtration Process

Industrial water filtration is necessary to remove substances that can clog or damage equipment, contaminate final products, or pose a health hazard to workers. The steps in industrial water filtration depend on the type of impurities that need to be removed.

The most common types of impurities removed by industrial water filtration are suspended solids, harmful bacteria, dissolved minerals and gases. The filtered water can be used in a variety of applications including cooling towers, boiler feed water, process water, and more.

What Is the Process of Water Filtration Step by Step?

The filtration technique involves forcing a liquid to flow through the pores of a substance known as a filter in order to separate suspended solid particles from a liquid. The filtrate is the liquid that has gone through the filter. Below is process of the filtration and has four steps:


Water from natural or industrial sources will be filtered as it enters the industrial filtration system.

This is a very important and indispensable part of the process in which large materials are kept out of the system, reducing the risk of clogging or otherwise disrupting the purification process.

Coagulation or flocculation

This step involves adding chemicals to the water to be treated, which then forms small, sticky particulate matter known as flocs in the water.

These flocs will attract larger and larger particles, some of the larger particles will sink to the bottom of the flocculation tank to be removed, and some will rise to the top to be skimmed out.


The process is the most important step in an industrial filtration system. Water is pumped into and through the filter, while accumulated floc is retained in the filter media.

Filters are made of different materials, and when water passes through the filter, the filter traps pollutants, impurities, particles, etc., and removes them.



Once the water has been thoroughly cleaned, it is piped into a sealed tank where chlorine and other disinfectants are used to kill any bacteria or other microbes that could have escaped the filtration process.

Other technologies such as ultraviolet purification, reverse osmosis, and ultrafiltration(filters with a pore size of 0.2 microns or smaller )can also perform secondary treatment and disinfection on filtered water.

What Is the Importance of Industrial Water Filtration?

Industrial water filtration is essential in many industries, including manufacturing, pharmaceuticals, food and beverage, and more. The process of industrial water filtration involves removing impurities, contaminants, and other unwanted substances from water used in industrial processes. Here are some reasons why industrial water filtration is crucial:

Protecting equipment: Impurities in water can cause damage to industrial equipment, leading to costly repairs and downtime.

Importance of Industrial Water Filtration

Improving product quality: Water quality can affect the quality of the products produced. Filtration ensures that the water used in production is free from contaminants that can affect product quality.

Meeting regulatory requirements: Many industries must meet regulatory requirements for water quality. Filtration ensures that the water used in industrial processes meets these requirements.

Reducing costs: Industrial water filtration can reduce costs associated with equipment repairs, downtime, and product recalls due to poor water quality.

Promoting sustainability: Industrial water filtration can reduce the amount of water used in industrial processes and promote sustainability.

What Are the Types of Industrial Water Filtration Processes?

Each of these processes has its strengths and weaknesses, and the choice of process depends on the specific needs of the industry and the water quality requirements. It is essential to work with a qualified water treatment expert to design and install an industrial water filtration system that meets the industry’s standards and regulations.

Membrane filtration

In the manufacture of foods and beverages, such as low-fat or whey proteins, the membrane filtration method is widely utilized. Two distinct streams are created from the feed as the liquid is passed through a membrane system. The four different kinds of membrane filtration are reverse osmosis, ultrafiltration, nanofiltration, and microfiltration.

Membrane filtration

Mechanical filtration

Modern innovation like mechanical filtration can meet industrial filtration needs at operating pressures greater than atmospheric pressure. This filtration procedure can be carried out using a configuration of media inside the main filter body.

Multi-Layer Filtration

The multi-layer filtration process employs a filter tank that has been divided into configuration sections and filled with various types and sizes of gravel that filter the avoidable particles. To get rid of the undesirable application color and odor, coal carbon applied in a carbon bed is useful.

Surface filtration

Surface filtration essentially uses the arrangement of media to form a barrier to remove unwanted particles, remove these particles from the fluid and keep them on the main contact surface of the media. Tea dust and tea are separated in one straightforward example.


Depth filtration

Depth filtration separates and collects various dust particles and pollutants using a media arrangement with a graded density structure. Particles are physically absorbed by the filter elements, which are constructed of materials like polypropylene, cotton, and fiberglass to get them out of the finished filtered liquid.

What Are the Industrial Uses of Water Filtration?

The main purpose of industrial filtration is to not consume harmful pollutants and protect equipment, remove pollutants to purify air, gas and water streams. It also improves the working environment, protects workers, and separates and isolates desired products from water streams or air.

Uses of Water Filtration

Industrial water filtration is used in various industries, including manufacturing, pharmaceuticals, food and beverage, and more. It is used to remove impurities, contaminants, and other unwanted substances from water used in industrial processes. The treated water can be used for cooling, heating, cleaning, and other industrial applications.


Industrial water filtration is essential for protecting equipment, improving product quality, meeting regulatory requirements, reducing costs, and promoting sustainability. Investing in high-quality industrial water filtration systems is necessary for the success and growth of many industries.
