Water Filtration Reuse, Recycle and Reduce: The New Mantra for Water Filtration
Use of sand in the water filtration process is a common practice. However, once used, sand cannot be reused or recycled. Additionally, it is a finite resource and is diminishing. Hence, innovative methods like AFM are making headway in the field of water filtration.
Sand has been used in the water filtration process for thousands of years now. However, modern filtration process requires sand to be changed after every 5-10 years. The biggest disadvantage of this filtration system is, sand once used in the filtration process cannot be reused and straight away goes to the landfill. This process not only leads to environment degradation but also incurs heavy transportation cost. This makes it imperative to use sand with discretion and also look for feasible alternatives to sand.
Exploring Alternatives for Traditional Filtration Methods
Replacing sand with AFM is a cost-effective and an environment-friendly way to resolve this ecological issue. The advantage with this process is that AFM can be recovered and upcycled for reuse. Dryden Aqua, a Scotland based company, offers an AFM water filtration method that uses waste container glass as a water filtration media.
How is it manufactured? AFM is manufactured from green container glass in a closed loop process as it has unique catalytic properties. Glass, which is normally destined for landfill, is transformed into a molecular sieve – AFM. This means, it also works as a waste management system since waste glass is upcycled into a high value product.
A Precise Particle Size is Important
The glass is reduced to a very precise particle size and particle size distribution. The surface of every grain is then turned into a mesoporous catalytic selective molecular sieve that adsorbs particles and chemicals such as some priority substances that should not be there in the water. The AFM is recharged and ready to use again by backwashing it with water. This backwash removes the particles as well as chemicals that have been removed during the run phase. The nano-structure of AFM is configured to trap and hold specific molecules.
