How to Select Best Water Purifier You?

Nowadays the water purification system has become an important home utility appliance in urban living because the water you may be getting from a tap or borewell may not be suitable for direct consumption so when selecting a suitable water purifier for home use, it's important to consider several key parameters based on the water quality in your area, health needs, and budget. Here are the best parameters you should consider before buying a water purifier for your home:

1. The Source of Your Water

• Municipal Tap Water Supply (Generally Soft Water): Generally treated and low in TDS (Total Dissolved Solids), but may still contain chlorine, bacteria, or soluble particles.
• Borewell/Well (Generally Hard Water): Often high in TDS, hardness, and may contain harmful minerals like arsenic, fluoride, and iron.
• Mixed Supply: A combination of municipal and borewell water may need more complex filtration because the stability or uniformity of raw water input to the water purifier does not always remain the same.

2. The TDS (Total Dissolved Solids) Levels in Raw Water

• Low TDS (<200 ppm): UV or UF purifiers combined with a polypropylene filter and an Activated Carbon filter are suitable as they disinfect the water.
• 
  
• Moderate to High TDS (200-500 ppm): RO purifiers are ideal as they remove excess salts and minerals, hardness and heavy metals from the raw water.
• Very High TDS (>500 ppm): An RO+UV combination may be required to ensure effective purification.
• Recommended standards for drinking water: As per Bureau of India Standards (BIS) drinking water norms IS:10500 the drinking water TDS should be below 500 milligrams per litre.

3. The Types of Purification Technologies Available

• Reverse Osmosis (RO) Systems are best for high TDS water; they remove dissolved salts, heavy metals, and impurities.
• Ultraviolet (UV) Filter: Kills bacteria and viruses but doesn’t remove dissolved impurities; ideal for low TDS water.
• Ultrafiltration (UF) System: Similar to UV but removes suspended particles; works without electricity.
• NF + UV: Nanofiltration is Ideal for areas with moderate TDS of raw water which is mixed or highly contaminated water is available and you want most water recovery.
• RO + UV/UF: Ideal for areas with mixed or highly contaminated water is available.
• Activated Carbon Filters: Removes chlorine, and organic compounds, and improves taste and odour.

 4. The Storage Capacity

• For a small nuclear family (2-4 members), a 10-15 litre storage tank is usually sufficient.
• For larger and combined families, consider a purifier with higher storage or faster purification rates.

5. The Maintenance and Filter Replacement Recurring Cost

• Consider how often the filters need to be replaced and the cost of replacements.
• Look for models with filter change indicators.

6. The Water Recovery Rate

• RO systems typically discharge more wastewater. So opt for a purifier with a higher recovery rate (ideally >50-80%) to reduce wastage. And consider to reuse of wastewater in floor or toilet cleaning.

7. The Mineral Retention

• Some purifiers flush essential minerals. Look for models with a "TDS controller" or "mineral cartridges" to retain healthy minerals like calcium and magnesium.

8. The Electric vs. Non-electric Purifier

• Electric purifiers (RO/UV) are suited for areas with a continuous power supply.
• Non-electric purifiers (UF/Gravity-based) are better in areas with frequent power cuts.

9. Certification and Brand Reputation

• Look for certifications like ISI marking ( IS:16240 ) from BIS ( Bureau Of Indian Standards), and NSF to ensure the purifier meets safety and performance standards. The Academy Of Water Science provides the details training for domestic water purification systems. 
• Choose brands with a good track record for customer service and warranty.

10. The Budget

• Basic UV/UF purifiers are more affordable but may not suit hard water areas.
• RO systems are costlier but necessary for high TDS water. Factor in both upfront costs and long-term maintenance. So the less-known brand with a branded membrane could be the most economical option in the long run.

11. The Additional Features

• The Latest Smart features like app control, auto shut-off, and digital display can enhance user convenience.
• Portability: Some models are more portable or easier to install in rented homes.

12. The Model Design and Space

• You should consider the available space for installation and whether the design matches your kitchen’s aesthetics and convenience. 

Domestic Reverse Osmosis Water Purifiers Training

Domestic Reverse Osmosis Water Purifiers Training

is very important to understand the various types of water purifiers available in the water purification industry for different water sources like tap water, bore well water, pond water etc etc.

One Model Of water purifier can not be used for all types of water input water sources because the different sources of water may have different types of water impurities and physical loads also. 

Therefore on the basis of raw water supply water purifiers should be installed it requires basic components working principles and knowing how to be used for said purification

Training in domestic reverse osmosis water purifiers at various cities in INDIA is being conducted by the Academy of Water Science- AOWS to assemble, repair, maintain and installation of all types of water purifiers of domestic Reverse Osmosis technology based apart from Chennai, Training is available in other cities too 

This type of skill development training can be useful for starting freelancer RO Technician work, opening up own shop, taking a franchise of service centre of any reputed brand and having one can have own branding also.
