Frequently Asked Questions (FAQs)

What is RO?
Reverse osmosis is a process in which water molecules are forced through a semipermeable membrane of 0.0001 micron by water pressure. Thin Film Composite (TFC) – sheets are rolled up around a hollow central tube in a spiral pattern after being sandwiched together. The dimensions of these tubes are determined by the volume of water they need to handle.
The reverse osmosis purification process is primarily designed to reduce the salt content in water.

How does Reverse Osmosis Work?
Reverse Osmosis (RO) is an advanced water purification process that uses a semi-permeable membrane to deliver clean, safe, and great-tasting drinking water. Here’s how it works:
1. Semi-Permeable Membrane – The RO membrane acts like an ultra-fine filter, allowing only pure water molecules to pass through while blocking dissolved impurities such as salts, minerals, heavy metals, and other contaminants.
2. Pressure-Driven Process – Water is pushed through the membrane under pressure, separating clean water (permeate) from concentrated impurities (reject water).
3. Effective Purification – RO removes even the tiniest dissolved particles, ensuring your water is not just clean but also healthier and better-tasting.
By selectively filtering out contaminants while retaining water’s natural freshness, RO technology provides high-quality drinking water you can trust. -
How many stages could be in an RO?
The RO system comprises 7 distinct stages of purification: pre-filtration, sediment filtration, pre-carbon filtration, RO membrane, mineralizer, activated carbon, and membrane technology." However, these stages may vary from 1 to 7 depending upon the need and Quality of Water.

What is Purification Flow Rate?
The purification flow rate indicates how much water a filtration system (such as an RO membrane or filter) can process within a specific time period. It measures the efficiency and speed of purification, typically expressed in liters per hour (LPH) or gallons per day (GPD).
✔ Higher flow rate = Faster purified water output
✔ Lower flow rate = Slower filtration, but often finer purification -
What is the average life of a pre-filter?
The life of pre-filters varies based on type and usage conditions:
For Water Purifiers:
Sediment & Carbon Pre-Filters –Typically require replacement every 3-6 months
Heavy Usage/Hard Water Areas – May need more frequent changes
