Magnetic nanoparticles that can swiftly detect and extract pathogens from water

Water pollution is a pressing issue, with more than a quarter of the world's population living in water-stressed countries. While preventing water pollution at its source is ideal, innovations are needed to clean the oceans and manage the water crisis.

Magnetic nanoparticles are a promising innovation for swiftly detecting and extracting pathogens from water. These nanoparticles are made of metals with magnetic properties, such as iron, cobalt, nickel, and zinc. They are non-toxic, reusable, and eco-friendly, making them ideal for water purification. The process involves scattering the nanoparticles into the wastewater, allowing them to bind to contaminants, and then using an external magnetic field to separate the nanoparticles and the attached pollutants.

One of the main advantages of magnetic nanoparticles is their ability to target and bind to specific pathogens, such as bacteria, viruses, and parasites. For example, FeO and CuFeO nanoparticles are effective in removing E. coli and S. aureus, which are common waterborne bacteria. The nanoparticles can also be functionalized with other metals or biomolecules to enhance their pathogen-removal capabilities. For instance, copper, silver, and carbon nanotubes have been added to nanoparticles to improve their antibacterial behaviour.

Additionally, magnetic nanoparticles can play a role in breaking down organic pollutants in water. By coupling them with photocatalytic or catalytic materials, advanced oxidation processes can be developed to degrade organic compounds using sunlight or other forms of energy. This makes them particularly effective in treating water contaminated with dyes, pharmaceuticals, and pesticides, which are often resistant to conventional treatment methods.

Overall, magnetic nanoparticles offer a viable and innovative solution for water purification, especially in regions with poor sanitation facilities. They can swiftly detect and extract pathogens from water, ensuring access to clean and safe drinking water, which is crucial for a sustainable ecosystem.

Microfibre laundry filters that prevent synthetic microfibres from entering oceans

Laundry is a significant source of plastic pollution in the world's oceans. Synthetic microfibres from our clothes, bedding, and other textiles are shed during the washing process and enter our wastewater, eventually making their way into the environment. These microfibres account for about 2.2 million tons of microfibres entering the ocean each year, making textiles the largest known source of marine microplastic pollution.

Microfibre laundry filters are an effective solution to this issue. These filters attach to your home washing machine and prevent synthetic microfibres from entering the oceans. They are a smart, efficient, and cost-effective solution to instantly reduce water pollution. One such example is the Filtrol 160, a patented, reusable filter that easily attaches to your washing machine's discharge hose. It removes synthetic clothing fibres like polyester, nylon, rayon, and acrylic, as well as other debris such as sand, hair, and pet fur. When the filter gets full, it can be washed out, and the fibres can be disposed of in the bin.

Another option is the Gulp filter, which also uses self-cleaning technology and does not require replacement filters, thus reducing extra costs and waste. It is easy to install and can be set up at home without the need for a plumber. When Gulp becomes full, the microfibres can be emptied into the bin or sent back to the company for ongoing research or recycling into new products.

The Guppyfriend laundry bag and the Cora Ball are also popular choices for preventing microfibre pollution. These products claim to keep microplastics out of wastewater when washing clothes.

By using microfibre laundry filters, individuals can play a crucial role in reducing water pollution and protecting marine life from the harmful effects of synthetic microfibres.

Water-efficient technologies and practices, such as the OrbSys Shower, which recycles shower water

Water-efficient technologies and practices are essential to combat water pollution and ensure access to clean water, which is a basic human right. The OrbSys Shower is an innovative water-recycling solution that offers significant benefits in this regard.

OrbSys Shower, designed by Mehrdad Mahdjoubi, is a high-tech purification system that recycles water while you shower. It works on a closed-loop system, where hot water falls from the tap, undergoes instant purification to drinking water standards, and is then pumped back to the showerhead. This process ensures that the water remains hot and only requires slight reheating. As a result, the OrbSys Shower saves more than 90% of water usage and 80% of energy consumption compared to a regular shower.

The touchscreen control panel embedded in the wall allows users to monitor the system's status and adjust temperature and water flow precisely. The shower floor is also designed as an access panel, providing easy access for filter maintenance and replacement. The used filters can be sent back to Orbital Systems for recycling, promoting a circular approach.

The OrbSys Shower's purification technology effectively removes endotoxins, DNA, and micron-sized particles, resulting in cleaner water than what typically comes from a tap. This feature is particularly advantageous in areas with water shortages or water-related illnesses, as it provides access to purified water for drinking and other essential purposes.

In addition to the OrbSys Shower, there are other water-efficient technologies and practices worth considering. For example, microfibre laundry filters can be attached to home washing machines to prevent synthetic microfibres from entering oceans and water bodies, addressing a significant source of water pollution. Additionally, individuals can adopt plastic-free cosmetics and hygiene products, such as bar soaps, shampoo bars, and toothpaste tablets, reducing plastic waste and its impact on water pollution.

Wastewater treatment methods, such as bioaugmentation, which uses microorganisms to break down and remove contaminants

Water pollution is a pressing issue, with more than a quarter of the world's population living in water-stressed countries. While prevention is better than cure, we have reached a point where large-scale innovations are needed to clean the oceans.

Wastewater treatment methods are a crucial part of tackling water pollution. One such method is bioaugmentation, an emerging strategy that uses microorganisms to break down and remove contaminants. This process involves adding selected strains or mixed cultures to wastewater reactors to improve the catabolism of specific compounds. For example, studies have identified bacteria such as Acinetobacter sp. and Sphingomonas sp., which are capable of degrading nicotine. By using a synthetic wastewater reactor, researchers were able to increase nicotine removal from 10% to 98% through bioaugmentation.

Bioaugmentation can also be used to enhance the efficiency of biological cyanide removal. In a full-scale coke wastewater treatment process, bioaugmentation was applied using cyanide-degrading yeast Cryptococcus humicolus and unidentified cyanide-degrading microorganisms. However, this process had limited efficiency due to the poor settling performance of microbial flocs and the slow biodegradation rate of ferric cyanide in wastewater.

Veolia offers bioaugmentation and cleaning products, such as BioPlus, which enhance microbial populations, making them more stable and resistant to upsets. Their products can be tailored to treat different types of wastewater, including food and beverage wastes, paper manufacturing, and hydrocarbon-contaminated HPI wastes.

While bioaugmentation shows promise, it is still considered a procedure with unpredictable outcomes. To improve its effectiveness, advanced bioreactor design and operation in wastewater treatment plants are essential to create the proper environmental conditions for the most desirable microorganisms to thrive.
