Filtration refers to the separation of solids from liquid or gas substances (fluids). There are several filtration processes in use today but the basic idea is to use a medium through which only the desired fluid can pass leaving the unwanted particles behind. This article will focus on filtration methods used in various industries.
The demand for industrial filtration solutions is on the rise especially with the increased sensitivity to environmental pollution. The excessive use of environmentally hazardous chemicals in the factories, mines, commercial farms and transport sector in the 20TH Century has led to the development of several campaigns to save the planet. A good number of these campaigns were successful and led to the elimination of the use of dangerous substances such as DDT, PCBs and lead-based paint among others. Industrial filtration methods are used to help the industries limit the circulation of harmful substances in the air and water as well as consumer products such as foodstuff, cosmetics and prescription drugs etc.
Factors Contributing to Growth of the Industrial Filtration Market
In 2017, the Global Industrial Filtration Market raked in about 23 Billion dollars in revenue and it is estimated that the income will double by 2026 based on the current CAGR of 7.7%. The projected growth of this filtration market directly reflects increased global demand for the filters. The market projections in this sector are based on a wide range of factors, a few of which we will review in this article.
1. Public Policy
The major factor that has been driving the growth of the Industrial Filtration market is prohibitive national and international regulations. In a bid to improve quality of air and water, international bodies such as the World Health Organisation, W.H.O., set limits on the acceptable levels of certain substances in the air or microorganisms in safe piped water. In addition, the Environmental Protection Agency, E.P.A., was set up to enforce measures that protect the environment including waste management and monitoring green house gas as well as carbon emissions.
There are several policies that have been developed and enforced in recent years that have required companies to install and maintain good quality industrial filters in order to improve the quality of waste they release into the environment. As time goes by, the policies become more rigid and widespread consequently improving the demand for industrial filters globally.
2. Advances in Filter Technology
Innovation is a major market demand accelerator. As filter developers improve their products, the users desire them more. Industrial filter designers are now developing filters that not only help companies comply with set regulatory requirements but also take a step ahead of their competition by saving money, improving the quality of their products and increasing productivity.
Efficient industrial filtration processes will help a company save money by enabling them to use raw materials such as water more efficiently and can save on running costs by filtering warm air and redirecting it for heating purposes.
By using high-grade filters, companies in the food and beverage industry can improve the quality of their end products by eliminating more contaminants, odours and colours during the production process.
3. The growth of other Industries
Global industrial growth is a major contributor to the accelerating demand for industrial filters. Population increase has led to the growth of the food and beverage industry in many countries while advances in medical research have led to the growth of the Pharmaceutical Industry in others. These two industries alone are major drivers of the demand for industrial filters because their products are made for direct human consumption as such they must adhere to strict quality control standards.
Types of Industrial Filters
There is a wide range of industrial filtration systems in use today. The list below will highlight a few of these systems.
– Hot Filtration is commonly used when removing impurities from crystalline compounds when they have been dissolved in a suitable heated solvent.
– Cold-Filtration is mostly used in the food and beverage industry to identify and separate proteins, fatty acids or esters and other substances from the required fluid.
– Centrifugal Filtration is suitable for liquid or semi-liquid fluids. It separates high-density solids and liquids from low-density fluids by spinning the filtration equipment at high speed until and components separate.
– Gravity Filtration is performed by allowing the fluid to flow from a high level to a lower one through a filtration membrane. No additional equipment is necessary for this kind of filtration since all motion depends on the force of gravity.
The demand for industrial filtration system is definitely increasing quickly and the list of factors contributing to this growth is endless. With all the environmental conservation targets that have been set globally, we believe it is a good time to invest in the industrial filtration industry.
