A good water filtration system is the first line of defence in your home from the chemicals and pollutants of modern city life. Making the vital choice between filtration systems can be a massive headache – the deluge of technical terms, customisation options, and potentially indispensable features make for a tough decision.
In this article, we will be condensing and simplify the mountain of information available on the internet. For reference, we will be exploring the Hydroflux water filtration systems as an industrial standard. While this article is by no means exhaustive, it will give you a good grasp of what to look for in a water filtration system – and why Hydroflux will tick every one off your list!
4-Stage Filtration System
Stage 1: Sediment Filter
The first step of the process is the most basic, but no less crucial. A coarse filter of natural fibres traps large particles – such as rust, grit, and sand – from the source water. This step is important for extending the working life of the other filters, since large particles will rapidly clog up their smaller pores and slow the flow of water.
You’ll be glad to know that even with such a basic component, Hydroflux uses a Japanese-branded, Korean-manufactured filter known for strict quality control and adherence to regulation.
Stage 2: Pre-Carbon Filter
This second step is where the bulk of chemicals in your water is absorbed. Depending on the company’s design, either activated carbon granules or an activated carbon block can be used. The water flows over the large exposed surface area of the carbon, allowing the carbon to adsorb harmful chemicals in the water, such as chlorine compounds and volatile organic compounds (VOCs).
Here, Hydroflux offers either an activated carbon powder filter – finer and more effective than granules – or a compressed carbon block filter, depending on the model of your choice. Both filters are manufactured by Kuraray – a leading producer of carbon filters from Japan – and use carbon made only from coconut husks, a definite plus for the environmentally conscious!
Stage 3: NanFact Filter
The third step of filtration removes the finest of particles and bacteria. Either synthetic or modified natural fibres are used in this filter.
As the sole distributor in Singapore of the patented NanoFACT filter, Hydroflux has an uncontested edge at this step of filtration. Designed and manufactured by KX Technologies, USA, the NanoFACT filter has one of the finest filtration standards on the market. While ultrafiltration membranes only trap particles between 0.5 – 1 micrometres, the NanoFact filter boasts an incredibly fine pore rating of 0.001 micrometres. For comparison, the Escherichia Coli or E. Coli bacterium, which can cause food poisoning and pneumonia, is 0.5 micrometres wide, while the similarly dreaded salmonella bacterium is at least 0.7 micrometres wide – both well within the NanoFact filter’s ability.
This industry-disrupting ability is thanks to KX Technologies’ proprietary method of producing highly fibrillated – or finely branching – fibres. The small tendrils overlap and form a vast number of tiny pores that not only trap fine particles, but also allow water to flow efficiently. Besides eliminating microorganisms without harmful chemicals, the special fibre is also able to hold finer grades of activated carbon and remove harmful chemicals more thoroughly.
Stage 4: Alkaline Filter / Post-Carbon Filter
The final step of filtration comes in two options. An alkaline filter alkalises your water with natural alkaline, increasing its pH level and imbuing it with the potential benefits of alkaline water. The post-carbon filter, on the other hand, serves the humble but nevertheless useful function of absorbing any trace chemicals that made it past the other filters. Hydroflux’s systems offer a Korean-manufactured alkaline filter or a post-carbon filter from Kuraray.
