The escalating global population and rapid industrialization have significantly increased the demand for clean water. According to a 2024 report by the World Water Council, global freshwater demand is expected to rise by 55% by 2050. As a result, wastewater treatment and water purification have become critical, driving the adoption of nanofiltration membranes. These membranes offer superior filtration capabilities with lower energy consumption than reverse osmosis (RO) membranes, making them an attractive option for water softening, disinfection, and desalination. For instance, in China, the government’s focus on wastewater reuse, including its USD 14 billion initiative to combat water pollution, has propelled nanofiltration membrane adoption. Additionally, the increasing emphasis on reducing fouling and maintenance cycles through innovations such as anti-fouling coatings has enhanced operational efficiency and cost-effectiveness.

Rising Demand for Concentrated Food and Beverages

Nanofiltration membranes are gaining popularity in the food and beverage sector for their ability to naturally concentrate and purify products without degrading their quality. In 2024, the global food processing industry is expected to surpass USD 4.5 trillion, with significant demand for concentrated beverages and dairy products driving the use of nanofiltration technologies. These membranes enhance product shelf life and remove unwanted impurities like lactose from milk or certain salts from fruit juices.

Segmental Analysis

By Type

The polymeric segment is the most significant contributor to the market and is projected to exhibit a CAGR of 5.20% over the forecast period. Polymeric membranes, also called organic membranes, are nonporous structures composed of polymers. It includes a family of liquid separation technologies that are industry-leading in performance and effectiveness. These membranes are divided into four key categories: characteristics, performance, and specific separation attributes. In addition, the polymers that manufacture nanofiltration membranes are cautiously selected to ensure optimal performance in a chosen environment. However, compatibility with fluids administered and cleaning agents required to assist in hygiene and performance constancy are also considered while selecting the suitable polymer.

Inorganic membranes include metals, oxides, or elementary carbon in their structure or may have multi-layer supporting structures. These membranes can function in severe conditions and be highly selective and permeable for specific molecules. Inorganic membranes are manufactured as separate sheets and tubes if adequately permeable. In addition, solid membrane materials are preferably selective for O2 or H2 particles. Micro-porous membranes (0.5–2 nm) could be highly selective for H2O, CO2, and hydrocarbons. Meso-porous membranes (2–50 nm) are used as supportive structures or in water purification. Macro-porous layers (>50 nm) are used as support structures or in particulate filtration applications.

By Membrane Type

The tubular membrane segment is the highest contributor to the market and is projected to grow at a CAGR of 4.72% over the forecast period. Tubular-shaped membranes are not self-sufficient as they are located within a tube and manufactured using a distinct material. The material is the supporting layer for membranes as the position of tubular membranes is within a tube. The flow in a tubular membrane is usually inside out, as the attachment of the membrane to the supporting layer is quite frail. Tubular membranes have a diameter of around 5 to 15 mm; therefore, the membrane surface's size enables the processing of complex feed streams without plugging. Tubular membranes also have low packing density, resulting in high module prices.

A flat sheet (FS) membrane is a type of technology configuration. Flat sheet membranes have a planar configuration and are mostly rectangular. They are constructed to be immersed in the membrane tank and scoured with air to retain sludge flow via membrane channels. The flat sheet element may be called a cartridge, sheet, or, most commonly, a panel. The panels can be flexible, semi-rigid, or rigid, with the flexible panels being thinner. In addition, nanofiltration flat sheet membranes have a molecular weight cut-off range of 100–800 Daltons and cast-off solutes based on size and charge. Nanofiltration membranes have exclusive competence to cast off multivalent ions and fluctuating degrees of monovalent ions, which is a beneficial tool in the procedure.

By Application

The water and wastewater treatment segment dominates the global market and is predicted to exhibit a CAGR of 4.79% during the forecast period. Nanofiltration membranes are an extensively used membrane technology for water and wastewater treatment and other applications like desalination. Nanofiltration membrane technology is relatively recent and can be aqueous or non-aqueous. The key features of nanofiltration membranes are similar to those of UF and RO membranes. In addition, nanofiltration membranes function by both pore-size flow (convective) and solution-diffusion mechanisms. Due to lower energy consumption and better flow rates, nanofiltration membrane technology has displaced RO membrane technology in several applications. The nanofiltration membrane technology is used in various water and wastewater treatment in diverse industrial applications.

Processing food from raw materials necessitates larger volumes of high-quality water. Using membrane equipment plays a crucial role in milk, cheese, and whey protein production processes. Vegetable washing produces waters with high loads of particulate matter and some dispersed organics, which may also include surfactants. In addition, food processing for sale generates waste products during the cooking process, which are usually rich in plant organic material and might consist of flavorings, acids or alkalis, salt, and coloring material. Therefore, the food and beverage segment has generated a high demand for wastewater treatment plants to recycle and reuse wastewater.
