The 7-Step Purification Process: Why It Matters

Water is the essence of life, especially in a vibrant, bustling city like Kathmandu. However, ensuring that the water you consume daily is genuinely safe, crisp, and refreshing requires far more than basic filtering. It requires an uncompromising commitment to science and hygiene.

At Aqua Himshikhar, we don’t take shortcuts. Every single drop of water that enters our iconic 19L jars has undergone an exhaustive 7-step purification process designed to strip away impurities while retaining a natural, refreshing taste. Let’s pull back the curtain on how we do it.

Step 1: Multi-Grade Sand Filtration

The journey begins by passing raw water through specialized sand filters. This crucial first step acts as a heavy-duty barrier, capturing large suspended particles, dirt, and undissolved sediments. By the time the water leaves this stage, it is visually clear, but our work is only just beginning.

Step 2: Activated Carbon Filtration

Next, the water flows through beds of activated carbon. If you’ve ever wondered how we eliminate that harsh chlorine smell or organic compounds that affect taste, this is the secret. The porous carbon absorbs gases, volatile organic compounds, and odors, leaving the water smelling pure and tasting sweet.

"Purity is not an accident; it is the result of continuous, meticulous refinement."

Step 3: Micron Filtration

Before the water undergoes Reverse Osmosis, it passes through 5-micron and 1-micron filters. These incredibly fine barriers catch microscopic particles that the sand filter missed. This protects the delicate membranes used in the next step and ensures a flawless baseline of purity.

Step 4: Reverse Osmosis (RO)

This is the heart of our purification facility. Water is forced under high pressure through a semi-permeable membrane. The microscopic pores in this membrane are so small that they remove up to 99% of dissolved solids, heavy metals, pesticides, and microbial contaminants. It is purification at the molecular level.

Step 5: Ozonation

While RO removes contaminants, Ozonation acts as an absolute safeguard. Ozone gas—a highly reactive form of oxygen—is infused into the water. It instantly destroys any remaining bacteria, viruses, and pathogens. Unlike chlorine, ozone leaves no chemical residue and converts back into pure oxygen, ensuring the water remains entirely natural.

Step 6: Ultraviolet (UV) Treatment

As a final layer of defense against microorganisms, the water is bathed in Ultraviolet light right before it is bottled. UV light alters the DNA of any potential surviving microbes, rendering them completely harmless and unable to reproduce. Double protection means zero anxiety for your family.

Step 7: Automated, Hygienic Bottling

All of this purification would be meaningless if the jar wasn't spotless. Our 19L jars undergo an automated, high-temperature washing and sanitization process. The pure water is then bottled and sealed without any human touch, capped with tamper-evident seals to lock in the purity until it reaches your home.

When you crack open a fresh jar of Aqua Himshikhar, you aren't just drinking water. You are drinking the result of uncompromising engineering, rigorous testing, and a deep commitment to the health of our community.
