Having a taste of clean and clear water is important. Not only in households but in large factories and plants where manufacturing takes place. Water treatment/purification is the process of removing unwanted chemical compounds, organic and inorganic elements, and biological pollutants from water.
Distillation is the conversion of liquid into vapour to condense it back into liquid form. And deionization is also part of this process (ion removal via the extraction of dissolved salts). One of the primary goals of water filtration is to produce safe drinking water. Water purification also serves the requirements for clean and drinkable water in medical, pharmaceutical, chemical, and industrial applications.
The purification process reduces the concentration of contaminants like suspended particles, parasites, bacteria, algae, viruses, and fungus. Water purification comes in a number of sizes, from large (e.g., for a whole city) to small (e.g., for a single person) (e.g., for individual households).
The majority of communities rely on natural bodies of water for water purification and daily consumption. Groundwater or surface water resources include underground aquifers, creeks, streams, rivers, and lakes. As a result of recent technological advances, oceans and salty seas have also been used as alternative drinking and domestic water sources.

What exactly is water treatment?
Maintaining water treatment to maintain a clean supply for the world’s rising population has been a constant concern throughout human history. High-quality drinking water can be delivered and enjoyed all around the world. Thanks to considerable technological advances in water treatment, including monitoring and assessment.
In modern times, government authorities often regulate the quality of water that can be filtered. These rules, whether local, national, or even global, typically define the maximum amount of dangerous pollutants that can be present in safe water. Because it is practically difficult to assess water pollution levels just on the basis of appearance, numerous procedures. Such as physical, chemical, or biological tests, have been devised.
Some of the usual indicators examined to measure water quality and pollution levels include chloride, copper, manganese, sulphates, and zinc levels, microbial pathogens, radioactive materials, and dissolved and suspended particles, as well as pH, odour, colour, and taste.
Technologies in water treatment
Listed below are five of the most cutting-edge technologies for water purification that are expected to replace conventional methods in the not too distant future.
Nanotechnology
Nanotechnology refers to a wide range of techniques and technologies for modifying materials at the atomic and molecular levels. In comparison to standard water filtering treatments, nanotechnology-based water purification technologies are expected to be flexible, highly efficient, and cost-effective. A few of the common nanotechnology applications in water treatment include silver, copper, and zero-valent iron (ZVI) nanoparticles, nanostructured photocatalysts, nanomembranes, and nano adsorbents.
The improved surface-to-volume ratio of nanoparticles promotes chemical adsorption as well as biological particle adhesion at extremely low concentrations of contaminants. For the removal of metallic contaminants from water, nano adsorbents have special physical and chemical characteristics.
Carbon nanotubes (CNTs) are one of the most often employed nanomaterials in water and wastewater equipments supplier. The CNT-based filtering devices will remove organic, inorganic, and biological pollutants from water.
Many global companies are developing membranes constructed of nanoparticles to remove pollutants during the treatment process. Including Alfa Laval, Applied Membranes, DowDuPont, GEA Group, Inopor, and Koch Membrane Systems.
Photocatalytic water treatment
Because of its effectiveness in cleaning dirty water, photocatalysis for water treatment has grown in popularity in recent years. Water is purified by using photocatalysts and ultraviolet (UV) light.
Panasonic invented a method that connects the photocatalyst (titanium dioxide) to a commercial adsorbent and a catalyst known as zeolite, enabling effective photocatalyst separation and recovery from water for recycling. Titanium dioxide may mineralize a wide range of organic compounds, resulting in safe end products.
To separate compounds, the catalyst employs UV energy from the sun or artificial light. Photocatalysis can break down organic chemicals, estrogens, pesticides, dyes, crude oil, and microorganisms. Which includes viruses and chlorine-resistant diseases, and also inorganic substances like nitrous oxides.
The technique of acoustic nanotubes
Scientists at NASA’s Johnson Space Center devised the acoustic nanotube technology. It guides water through small-diameter carbon nanotubes utilizing acoustics rather than pressure.
The system uses an acoustically driven molecular screen containing carbon nanotubes that allows water molecules to flow through while inhibiting bigger molecules and impurities. It uses very less energy than standard filtration systems. And nstead of cutting impurities from water, it propels water away from them. Additionally, this technique eliminates the necessity of flushing the filter system.
Municipal water plants, medical facilities, labs, distilleries, desalination plants, industrial facilities, wastewater treatment plants, and the consumer part are the principal uses of acoustic nanotube technology. According to the researchers, the idea is scalable due to the integration of various filters. The enterprises may license Nasa’s patented acoustic nanotube technology and develop it into a commercial water filtration solution.
Aquaporin InsideTM
Aquaporin InsideTM technology is based on a biomimetic water treatment membrane design developed by Aquaporin, a Danish cleantech business. Aquaporins are proteins that allow water to flow through the cell membrane swiftly and selectively. These let the cell to respond to variations in hydrostatic and osmotic pressure by regulating its volume and internal osmotic pressure.
The unique geometry of the aquaporin channel allows water molecules to flow through while blocking all other substances. In order to create artificial bio-mimetic membrane devices, organic bio-mimetic membranes are often employed. These devices are used in water purification and filtration devices for both industrial and domestic purposes.
Aquaporin Inside membranes are the only ones on the market that use aquaporins to purify water. Either forward or reverse osmosis (FO/RO) procedures can use the membranes. The Aquaporin Space Alliance (ASA), a joint venture between Aquaporin and Danish Aerospace Company (DAS). It is commercializing the unique Aquaporin InsideTM technology in space applications and space programs in collaboration with European and US-based businesses.
AVF – Automatic Variable Filtration.
AVF (Automated Variable Filtration) is a straightforward procedure wherein the descending flow of filter material cleans the higher flow of influent. It removes the requirement for any further filter media cleaning method or freshwater.
The AVF approach uses a configurable array of continually cleaned descending bed filters. The system’s two-stage architecture includes two sets of media filters that may operate in serial or parallel mode. The process delivers water of equal quality as microfiltration for a fraction of the cost of low-pressure membranes. It has no moving components and uses less electricity, resulting in lower operating and maintenance expenses.
Municipal drinking water and wastewater treatment, and also wastewater recycling and reuse, transmembrane pre-filtration, and desalination are all appropriate applications for AVF systems. Some of the key firms active in the development of AVF technology-based goods and services are R2O Water Technologies, Process Research ORTECH (PRO), and Eureka Forbes.
