The increasing use of nanofiltration membranes in the domains of wastewater treatment and water purification serves as a prominent catalyst for the expansion of the market. Nanofiltration membranes are technologies for separating dissolved molecules and ions from water and other liquids. These membranes have pore diameters ranging from 1 to 10 nanometers, smaller than those of microfiltration and ultrafiltration membranes but larger than those of reverse osmosis (RO) membranes. Polymers, ceramics, and metals are used to construct nanofiltration membranes. They are designed to eradicate specific water contaminants, including dissolved salts, organic molecules, and bacteria.

Nanofiltration membranes enable water and small particles to pass while larger particles and molecules are retained. Thus, nanofiltration membranes are frequently employed in water treatment applications, such as desalination, wastewater treatment, and drinking water purification. They are also utilized in the food and beverage sector to remove impurities from liquids and concentrate or separate particular components. In recent years, nanofiltration membranes have acquired popularity owing to their high selectivity, which enables the precise separation of various molecules and ions.

Nanofiltration Membranes Market Growth Factors

High Demand for Wastewater Treatment and Water Purification

The global water demand is constantly under pressure, and water treatment has special relevance due to the increasing global population and improving living standards.

Competitive Analysis of the Global Nanofiltration Membranes Market:

Segmental Analysis

By Type

The polymeric segment is the largest contributor to the market and is projected to exhibit a CAGR of 5.20% over the forecast period. Polymeric membranes, also referred to as 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 selected environment. However, compatibility with fluids administered and cleaning agents required to assist in hygiene and performance constancy are also considered while selecting the right 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 extremely 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 extremely 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 difficult 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 membrane 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 a relatively recent development and can be aqueous or non-aqueous. The key features of nanofiltration membranes are similar to 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. The utilization of membrane equipment plays a crucial role in the production processes of milk, cheese, and whey proteins. 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 include 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.
