Lack of access to safe drinking water and water shortages across the globe pose a major threat to people across the world. Nanotechnology is one of the emerging technologies that can play a key role in resolving water crisis by introducing inexpensive and effective water treatment techniques. In water treatment, nanotechnology is used for water purification or filtration by means of nanoscopic materials such as alumina fibers and carbon nanotubes. It also employs nanocatalysts, zeolite filtration membranes, titanium oxide nanowires, palladium nanoparticles, and magnetic nanoparticles. Nanotechnology in water treatment offers various advantages over the conventional water treatment process, such as large surface area, high efficiency, enhanced absorption, and low pressure requirement across the filter.
Nanotechnology in Water Treatment Market: Key Segments
The global nanotechnology in water treatment can be segmented in terms of nanomaterial and application. Based on nanomaterial, the nanotechnology in water treatment smarket can be segmented into nanoadsorbents, nanometals/nanometals oxides, and nanomembranes. Nanomembranes are used for removal of contaminants and softening of water in any type of water or wastewater treatment system. Nanomembrane-based water treatment process is highly reliable and it provides a physical barrier for contaminants, based on their molecule size and pore size. Nanomembranes require a large amount of energy during the water treatment process. Water treatments that use nanometals or nanometals oxides, such as titanium dioxide and nanosilver, present a low-cost water purification technique. These nanomaterial are highly abrasion resistant and super magnetic in nature. They offer short diffusion distance. Nano adsorbents aid in the removal of heavy metals, organic materials, and bacteria from water. They have high adsorption rate and surface area, but their production cost is high.
Based on application, the global nanotechnology in water treatment market can be segmented into potable water treatment and industrial water treatment. Nanofiber membranes in potable water treatment application are gaining momentum in the water treatment industry, due to their structural properties such as large surface area and high adsorption rate. These membranes help in improving the water quality through their antimicrobial activity. All these factors are boosting the demand for nanotechnology in water treatment.
Nanotechnology in Water Treatment Market: Trends & Demands
Rising demand for affordable and clean drinking water coupled with increasing emphasis to clean industrial water pollutants in groundwater is driving the global nanotechnology in water treatment market. However, high production costs and commercialization of nanomaterial on a large scale are expected to hinder the nanotechnology in water treatment market during the forecast period. Nevertheless, rising research activities in the field of nanotechnology and discovery of low-cost and efficient nanomaterials are likely to fuel the nanotechnology in water treatment market in the next few years. For instance, researchers have recently developed a thin-film, molybdenum disulfide (MoS2) membrane with nanopores for desalination. This membrane filters 2–5 times higher amount of water than the conventional filter.
Nanotechnology in Water Treatment Market: Regional Outlook
Based on region, the global nanotechnology in water treatment market can be classified into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. North America held a major share of the global nanotechnology in water treatment market in 2017. Increasing expenditure on R&D in the field of nanomaterial and industrial wastewater treatment is boosting the nanotechnology in water treatment market in North America. The market in Asia Pacific is expected to expand at a significant pace during the forecast period. Increasing government efforts to provide safe drinking water across developing economies such as China, India, Indonesia, and Thailand are expected to fuel the nanotechnology in water treatment market in the region during the forecast period. The market in Latin America and Middle East & Africa is expected to expand at a moderate pace in the next few years. Rising awareness regarding nanotechnology across South Africa and GCC and increasing expenditure by governments and NGOs to provide water free from contaminants are likely to provide lucrative opportunities to manufacturers operating in the nanotechnology in water treatment market in Middle East & Africa in the near future.
