100 LPH-Automatic RO-TDS upto 1500-Recovery 50 %

Institutions, offices, hotels, and small-to-mid-size commercial operations that need a steady, unattended supply of purified water outgrow domestic RO purifiers fast — a single household unit simply isn't built for continuous, high-volume output. The Pearl Water 100 LPH Industrial RO Plant is a fully automatic, plug-and-play reverse osmosis system built to deliver 100 litres of purified water per hour, running heavy-duty cycles of up to 10 hours non-stop with negligible manual intervention. Built in fully stainless-steel construction and handling inlet water with TDS up to 1,000 ppm at a 50–70% water recovery rate, it's ISO certified and sized specifically for small schools, hospitals, institutes, offices, hotels, and residential complexes that need dependable purified water without the complexity of a full industrial installation. Pearl Water's guide on what an industrial RO plant is and how it works covers where this capacity typically fits relative to smaller and larger systems.

Who Needs a 100 LPH RO Plant?

Choosing the right RO plant capacity comes down to how many people you're serving and how much water they need daily. A 100 LPH system produces 100 litres every hour it runs — so over a typical 8–10 hour operating day, that's roughly 800–1,000 litres of purified water, enough to comfortably cover drinking, cooking, and light operational water needs for a small institution or commercial site.

This capacity is commonly used by:

• Small schools, hospitals, and institutes where consistent daily access to purified water matters but overall demand isn't large-scale.

• Small to mid-size offices needing reliable drinking water without domestic purifiers scattered across floors.

• Hotels and hospitality businesses covering both guest drinking water and kitchen use.

• Residential complexes supplying purified water to a shared facility rather than individual units.

• Small commercial or light industrial operations needing modest volumes of purified water for cleaning, production support, or general use.

If your daily requirement is noticeably higher — larger institutions, food processing, or facilities serving hundreds of people — Pearl Water's 200 LPH, 250 LPH, or 500 LPH systems are worth comparing before committing to this capacity.

How Does the 100 LPH RO Plant Work?

This system runs through a complete multi-stage filtration process, not just a single membrane:

1. Raw water pump forces incoming raw water into the filtration system.

2. Dual Media Filter (DMF) removes larger suspended impurities from the raw water.

3. Activated Carbon Filter (ACF) removes color and odor from the water ahead of the RO stage.

4. Doser injects anti-scalant to prevent scaling buildup on the RO membrane over time.

5. Micron filters remove fine particles down to 5 microns, protecting the membrane from finer sediment.

6. High-pressure pump (SS 304 construction) pushes water through to the RO membranes at the pressure needed for reverse osmosis to occur.

7. RO membranes (0.0001 micron) remove up to 90% of dissolved salts and heavy metals such as lead and mercury.

8. Online rotameter measures the permeate (purified water) flow rate in real time.

9. Microprocessor-based control panel manages the entire process automatically, minimizing manual intervention.

The whole system sits on a robust, MS powder-coated frame that keeps the skid compact and stable for a fixed installation.

Standard 100 LPH vs Pearl Lite Series 100 LPH

Pearl Water also offers a 100 LPH Pearl Lite Series variant at a notably lower price point. If you're comparing the two:

If your facility runs the plant for extended hours daily under continuous demand, the standard heavy-duty build is generally the safer long-term choice. For lighter or intermittent use, the Lite Series may offer better value — confirm the exact build specification difference with Pearl Water before deciding, since construction details can vary between listings.

If your daily demand is higher than this capacity covers, compare the 200 LPH Semi-Automatic RO Plant, 250 LPH Automatic RO Plant, or 500 LPH Automatic RO Plant. For smaller or lighter-duty needs, the 50 LPH Automatic RO Plant or the 100 LPH Pearl Lite Series may be a better fit. For plants requiring finer pre-treatment ahead of RO, Pearl Water also offers a dedicated Ultra Filtration Plant.
