Our NuWater technology includes various cutting-edge systems for your water treatment needs. As a smart water treatment company, we provide solutions to common water problems, thereby uplifting local businesses and communities while at the same time protecting ecosystems and environments.
While some of these processes may seem similar, each plays a unique role in achieving your water treatment needs. We break down what each of our NuWater technology terms means.
Our NuWater Technology
Ultrafiltration (UF)
Ultrafiltration is the pressurised separation of water and colloidal solids using membrane technology. At NuWater, we use a low-pressure, 0.03-micron barrier to remove solids, bacteria, and viruses. It provides consistent water quality (< 0.1 NTU) no matter the variation in feed water quality.
Furthermore, NuWater’s hollow fibres are made out of resistant H-PVDF, allowing for excellent chemical resistance and consistent long-term performance.
Nanofiltration
Nanofiltration (NF) is one of the pressure-driven membrane separation methods in which elemental components with a molecular weight of 350–1000 Da (Dalton) are retained. It’s one of the modern filtration techniques used frequently and for diverse applications. However, it’s most commonly used to reduce hardness-related salts.
The pores in NF membranes are smaller than UF membrane pores, typically about 1–10 nm but larger than in RO membranes. An NF membrane discards colloids and organic composites, including lower molecular mass and divalent salts.
Reverse Osmosis (RO)
Reverse Osmosis is a membrane technology that uses a very fine filtration process, occurring at a molecular level. The process involves forcing water through a semi-permeable membrane, allowing only for a specific size of the molecule to pass, and rejecting the rest.
Therefore, this process produces pure water that is diverted to the storage tank for use. The rejected water carrying the minerals in a high concentration is drained off as waste or retreated to achieve a higher water recovery.
Microfiltration
Microfiltration is a separation technique during which micron-sized particles, like sediment and bacteria, are removed from the water to purify it for daily use. The pores of these filters applied here are microscopic in size, which differentiates this process from other filtration methods.
AFM or Glass Media Filtration
Activated Filter Media (AFM) is a direct replacement for sand in any type of sand filter and can double the performance of a sand filter system. It’s bio-resistant, prevents bacterial growth, and offers an average of 50% reduction in backwash water consumption. In addition, this type of media has an extremely long service life compared to the alternative.
Birm Filtration
The “Burgess Iron Removal Method”, or Birm filtration, involves the infusion of manganous salts to an aluminium silicate core. It’s a granular filtration medium, black in colour, which is housed in a typical media filtration vessel. Contaminated water filters through the media to remove particles such as dissolved iron and manganese.
Carbon Filtration
The Activated Carbon filtration uses absorption rather than filtration, as harmful contaminants are absorbed by the activated carbon when exposed to raw water to be treated.
Activated carbon filters are small, granular pieces of carbon that have been treated to be extremely porous. Chemical absorption is when organic compounds in the water react chemically with the activated carbon applied, causing harmful particles to stick to the filter media. The more porous the activated carbon, the more contaminants it will capture.
