75GPD Aquacare RO (Pump)

Domestic RO System – 75GPD Under-Counter Reverse Osmosis

n

The Domestic RO System – 75GPD Under-Counter gives you clean, safe drinking water right at your sink. This five-stage system is built for households that want high performance without taking up counter space. With a capacity of 75 gallons per day (≈190 liters/day), it handles daily drinking and cooking needs reliably.

n

Before installing this Domestic RO System, it is necessary to perform a water quality analysis. That helps ensure your feed water (municipal or otherwise) is compatible. High levels of TDS, hardness, iron, or chlorides can damage the membrane and reduce effectiveness. Proper pre-filtration or conditioning can protect the system and extend its life.

Five-Stage Filtration & How It Works

n

n
1. Stage 1 – 5-Micron Sediment Pre-Filter: Removes sand, rust, silt, and large particulates to protect downstream filters.

n

2. Stage 2 – Activated Carbon Pre-Filter: Removes chlorine, organic compounds, and improves taste and odor.

n

3. Stage 3 – Carbon Block Pre-Filter: Offers finer filtration to catch smaller particles and retain more contaminants before the RO membrane.

n

4. Stage 4 – 75 GPD RO Membrane: The heart of the system; eliminates dissolved solids, heavy metals, microbes, etc., delivering purified water.

n

5. Stage 5 – Inline GAC (Post-Carbon) Filter: Polishes the water, improving flavor and ensuring clean output just before use.

Installation & Care Tips

n

n
• Always check water quality first; test TDS, chlorine, hardness, iron etc.

n

• If feed water has high chlorine, use quality carbon pre-filters to protect membrane.

n

• Mount system under the sink, ensure good drainage, and avoid freezing or direct sunlight.

n

• Replace filters according to schedule: sediment & pre-carbon yearly; RO membrane every 1-2 years depending on use and water quality; post-carbon as needed.
