What Is a 120 LPH RO System?

A 120 LPH RO is a commercial-grade reverse osmosis system designed to deliver 120 liters of purified water every hour. It is stronger than a household RO and uses industrial-grade membranes, pumps, and filtration components.

This capacity is perfect for:

• Small to medium restaurants

• Hotels and cafes

• Schools and coaching centers

• Corporate offices

• Clinics and hospitals

• Hostels, PGs, and apartments

• Large families with 15–50 members

A 120 LPH RO system ensures an uninterrupted supply of clean water regardless of fluctuations in water quality.

How 120 LPH RO Works

The RO process includes:

1. Sediment filtration (removes dirt and sand)

2. Carbon filtration (removes chlorine and chemicals)

3. High-pressure pump boosting

4. RO membrane purification

5. Optional UV or UF treatment

6. Mineral balancing or TDS control

This multi-stage purification guarantees safe, clean, mineral-balanced water.

Reverse Osmosis Technology Overview

Reverse osmosis is one of the most trusted purification methods worldwide. It works on the principle of pushing water through a semi-permeable membrane under high pressure. The membrane has microscopic pores that allow only water molecules to pass through while blocking contaminants.

What RO Removes

• TDS

• Hardness-causing minerals

• Heavy metals (lead, arsenic, fluoride)

• Pesticides and industrial chemicals

• Bacteria and viruses

• Unpleasant taste and odor

This makes RO ideal for borewell water, tanker water, municipal supply, and contaminated ground sources.
