Macrofiltration Market Size

The global macrofiltration market size was valued at USD 8271.29 million in 2024 and is projected to reach from USD 8767.57 million in 2025 to USD 13974.17 million by 2033, growing at a CAGR of 6% during the forecast period (2025-2033)

Macrofiltration is the process of removing non-solute solid particles larger than 1.0 microns from water. By passing through a porous medium or membrane, the particles are filtered. Solid particles are suspended in hard and dirty water. The filter membranes catch the contaminants. Ion exchange membrane units similarly capture the resin and carbon particles. The efficiency of the filters that maintain and catch naturally occurring particles can be improved. There are distinct product lines of mesh screens and filters designed to satisfy the requirements of macrofiltration.

The technique of macrofiltration is widely employed in water and wastewater treatment facilities. The macrofiltration technique includes filter presses with large-gauge pores and dead-end type filters. This method of harvesting is ideal for this particular type of filamentous algae due to its size and resistance to clogging membrane screens and flowing through holes. The procedure is quick, effective, low-cost, and retains the most algal biomass possible. The macrofiltration process can be more effective using filter aids like diatomaceous earth.

Product Insights

The global market is divided into granular micro filters, leaf tubular and press filters, filter press filters, belt filter press, bag filters, auto backwash filters, and others. The granular micro filter segment is responsible for the largest market share and is projected to grow at a CAGR of 5.0% over the forecast period. The granular microfilter filters water through granular material (regularly sand) while suspended solids (sand, clay, iron, and aluminum flocs) are retained. Sand, gravel, diatomaceous earth, coal, and other minerals are used in granular microfiltration. There are several plans and scales (sizes) of granular microfilters. Some examples are roughing filters, bucket filters, barrel or drum filters, and bucket filters. Granular media are used for household and community water treatment.

However, a granular microfilter also has several disadvantages. It is ineffective in removing chemicals that do not attract carbon, such as sodium, nitrates, heavy metals, and fluoride. In addition, it is not effective against a few pathogenic bacteria and viruses. However, this issue can be resolved by adding trace amounts of silver to slow down bacterial growth.

Auto Backwash type self-cleaning filters work on a flow direction of outside to inside. Auto backwash filters are used in various applications such as juice, beer, sugar, vinegar, edible oil, wine, vegetable oil, electrolyte, electro galvanizing solution, lithium processing, etc. These filters require high maintenance.

Moreover, as the scarcity of high-quality potable water sources increases, non-potable fresh water, such as well water, is increasingly utilized. These water sources contain clogging factors such as clay particles, sand, silt, and organic matter. These contaminants build up on the inner surface of the filter screen and cause a filter cake to develop. If the cake is not cleaned, it may become thick enough to clog the filter. This results in reduced performance of the filter and clogged emitters, which is one of the significant challenges of this filter. The market is growing because of the rising demand for filtered water in the food and beverage industry and the residential sector to ensure product safety.

Industry Verticals Insights

The global market is segmented into water and wastewater, mining and metal, chemical and pharmaceutical, food and beverage, paper and pulp, and others. The water and wastewater segment owns the highest market share and is projected to grow at a CAGR of 5.9% during the forecast period. Applying macrofiltration in water and wastewater treatment includes wastewater treatment, reuse, and desalination. Filters that are used in water treatment are pressure sand filters (PSF), disc filters (DF), and mesh filters (MF). Urbanization and industrialization in Asia-Pacific have led to more freshwater consumption.

In addition, oil and grease, radioactive, iron and steel, chemical, and other industrial waste are released straight into the ocean or rivers because industrialization needs more water. This discharged waste is harmful to aquatic life as well as to human health. The effluents are separated, and both filtration and disinfection are done simultaneously, which removes the extra cost of the chemical's dosage.

The paper and pulp industry is the highest water-using sector. The process consists of two steps such as pulping and bleaching. First is pulping, in which wood chips are used as a raw material that is treated to remove lignin and improve fibers for papermaking. Bleaching is the last process that aims to whiten and brighten the pulp. All these processes require fresh water during the processing of each step, which also uses macrofiltration for the filtration process.

In addition, paper and pulp wastewater usually contains organic compounds and fibers that produce high concentrations of chemicals such as sodium sulfide, bisulfites, sodium carbonate elemental chlorine or chlorine dioxide, and sodium hydroxide. It also includes biochemical oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids. These organic compounds and fibers can hamper aquatic and human health when released into the water. Therefore, to reduce this, membrane filters are used that are projected to increase the demand for the macrofiltration market automatically.
