In a country like India, where rivers, groundwater, and municipal supplies form the backbone of daily water needs, the quality of what flows from the tap often raises concerns. Rapid urbanization, industrial growth, and agricultural runoff have introduced a mix of invisible threats into water sources, from dissolved salts to harmful microbes. Families across cities and villages seek reliable solutions that deliver safe drinking water without compromise.
SKF Elixer addresses this reality with its RO UV UF Technology Water Purifier, a system engineered to tackle diverse contaminants through layered filtration. This multi-stage water purification system stands out for Indian households, combining precision technology to produce water that supports health and daily wellness.
Understanding the Difference Between RO, UV, and UF Filtration
Water purification involves targeted methods to remove specific impurities, and grasping these differences helps in appreciating integrated systems. Reverse Osmosis (RO) operates by pushing water under pressure through a semi-permeable membrane with pores as small as 0.0001 microns.
This process effectively strips away dissolved solids like salts, heavy metals, and chemicals that elevate Total Dissolved Solids (TDS) levels, common in borewell water across states like Rajasthan or Tamil Nadu where TDS can exceed 1,000 ppm. RO is particularly vital in hard water zones, reducing risks from arsenic in West Bengal groundwater or fluoride in parts of Madhya Pradesh.
Ultraviolet (UV) filtration, on the other hand, employs high-intensity UV-C light at 254 nm wavelength to disrupt the DNA of microorganisms, rendering them inactive. It targets bacteria such as E. coli, viruses like rotavirus, and parasites without adding chemicals or altering taste. In regions prone to monsoon-related biological contamination, such as Kerala or Assam, UV proves indispensable for disinfecting water from rivers or tanks.
Ultrafiltration (UF) uses membranes with pores around 0.01 microns to physically block larger particles, suspended solids, and microbes while allowing beneficial minerals to pass through. It excels in low-TDS surface water scenarios, like municipal supplies in urban Maharashtra, retaining essential elements like calcium and magnesium that contribute to bone health and enzymatic functions.
Each technology addresses a unique aspect: RO for dissolved impurities, UV for biological threats, and UF for particulate matter. When standalone, they leave gaps, but combined in an RO UV UF Water Purifier, they create a comprehensive barrier suited to India’s varied water profiles.
How SKF Elixer Combines Triple Purification for Maximum Safety
SKF Elixer’s RO UV UF Technology Water Purifier integrates these three processes in a sequential, efficient setup. Water first enters the UF stage, where a hollow fiber membrane traps silt, rust, and larger microbes, preventing them from clogging downstream components.
This pre-filtration extends the life of the RO membrane, which then handles the heavy lifting by removing up to 99% of TDS, including lead, mercury, nitrates, and pesticides often found in agricultural runoff.
Post-RO, the water flows into the UV chamber, a quartz glass tube housing a UV lamp that delivers a dose of at least 40 mJ/cm², sufficient to inactivate 99.99% of pathogens. This step ensures biological safety even if source water harbors seasonal outbreaks. Finally, a post-filtration polish via activated carbon refines taste and odor.
The system includes TDS control, allowing adjustment to maintain levels between 50-150 ppm, aligning with BIS standards for drinking water. For a family of five consuming 15-30 liters daily, this setup processes water at rates up to 10 liters per hour in domestic models, with smart indicators for filter replacement.
High-quality fittings eliminate leaks, and the design minimizes rejection water, far better than traditional RO systems that waste up to 70%. This combination in the SKF Elixer Water Purifier delivers layered protection, adapting to local challenges like high salinity in coastal Gujarat or microbial loads in rural Uttar Pradesh.
Common Impurities Removed by RO UV UF Systems
Indian water sources carry a spectrum of contaminants, and RO UV UF systems target them systematically. Dissolved salts, measured in ppm, are primary culprits; RO reduces TDS from 2,000 ppm in brackish areas to under 100 ppm, preventing scale buildup in utensils and health issues like kidney stones.
Heavy metals such as arsenic (up to 50 ppb exceeding WHO limits of 10 ppb), lead from old pipes, and mercury from industrial discharge are filtered out by RO’s dense membrane. Chemical pollutants like pesticides (organophosphates from farmlands) and nitrates (from fertilizers, often 45 mg/L in groundwater) are also removed, reducing cancer and methemoglobinemia risks.
On the biological front, UV neutralizes bacteria (E. coli counts in contaminated supplies can hit 10^5 CFU/100 ml), viruses, and cysts like Giardia. UF handles turbidity from suspended clay or organic matter, common in rainwater harvesting, clarifying water to below 1 NTU.
Odor-causing compounds like hydrogen sulfide (rotten egg smell in some well water) and chlorine residuals from municipal treatment are adsorbed in carbon stages. In essence, these systems eliminate over 95% of harmful entities, transforming murky or saline input into clear, safe output.
Benefits of Choosing a Multi-Stage Water Purifier for Indian Homes
Households in India face fluctuating water quality—municipal chlorine one day, borewell hardness the next. A multi-stage water purifier like SKF Elixer’s offers versatility, handling TDS spikes during summers or microbial surges in monsoons without separate units.
Health-wise, it lowers waterborne disease incidence; India reports over 1.5 million diarrhea cases annually, many linked to impure water, and triple purification cuts this by ensuring pathogen-free supply. Mineral balance prevents deficiencies; retained calcium supports the 300-400 mg daily requirement for adults.
Economically, at costs starting around ₹10,000-₹20,000 for domestic models, it saves on bottled water (₹40-50 per 20 liters) and medical bills from illnesses. Water savings translate to 500-1,000 liters monthly conserved per family. Taste improvement encourages higher intake, vital in hot climates where dehydration affects 20-30% of urban dwellers.
Installation fits compact kitchens, with wall-mount options, and maintenance involves replacing filters every 6-12 months, with parts available locally to avoid full unit swaps.
Why SKF Elixer’s Technology Ensures Long-Term Health Protection
Sustainability and durability define SKF Elixer’s approach. Energy-efficient pumps consume under 50 watts, and eco-designs reduce plastic waste by promoting tap over bottles. For long-term health, consistent purity guards against chronic exposure; cumulative arsenic intake, for instance, links to skin lesions in affected districts, averted here.
In growing families, from toddlers needing 1-2 liters daily to elders, balanced water aids digestion, skin health, and immunity. Corporate and institutional extensions ensure workplace hydration, but domestic focus prioritizes home as the health foundation.
SKF Elixer’s mineral water systems comply with ISO and BIS certifications. This technology invests in preventive health, yielding dividends in vitality over years.
The RO UV UF Water Purifier from SKF Elixer represents a thoughtful integration of science and practicality, tailored for Indian realities. It transforms everyday water into a reliable source of nourishment, fostering healthier lives one glass at a time.
