Reverse Osmosis System

Reverse Osmosis System – 3-Stage Filtration for Brewing Water

Since beer consists of 90-95% water, using high-quality water is crucial for brewing.

While good-tasting water can produce good beer, the mineral content in water significantly impacts bitterness perception, malt character, and mouthfeel.

With this 3-stage reverse osmosis system, you can create pure water, providing a blank canvas free from nearly all minerals. This allows you to customise your brewing water by adding specific minerals to match different beer styles.

Why Use Reverse Osmosis for Brewing?

• Customisable Water Profiles – Starting with purified water allows precise control over mineral content.
• Improved Beer Consistency – Eliminates fluctuations in tap water quality for reliable results.
• Removal of Contaminants – Filters out chlorine, chloramine, pesticides, heavy metals, and dissolved solids that can negatively affect beer flavour.
• Better Hop and Malt Expression – Adjust water chemistry to enhance hop bitterness or malt richness, depending on the beer style.

Optimise Your Brewing Water with Reverse Osmosis

Reset your water profile and create a custom water recipe tailored to your beer style. This reverse osmosis system efficiently removes calcium carbonate (lime), chlorine, and other unwanted elements at 2.1 bar pressure, eliminating the need for a booster pump.

This minimum pressure is below the standard distribution range in France, which typically falls between 2.75 and 4 bar.

The system operates efficiently from 2.1 bar, but at 3 bar and 12°C, it produces approximately 12 litres per hour with a 93% filtration efficiency. Performance improves after 30 minutes of use, as the membrane requires initial hydration.

3-Stage Reverse Osmosis System Includes:

• - Tap adapter
• - Inline sediment filter (5µm)
• - Inline carbon filter (5µm)
• - 75 GPD ULP (Ultra Low Pressure) RO membrane
• - Membrane housing
• - 5 angled fittings (including 1 extra)
• - 1 straight fitting
• - 3 meters of 1/4″ tubing (1 meter each in white, red, and blue)
• - 450ml flow restrictor
• - 4 clips for securing the thick membrane housing and filters

Maintenance & Filter Replacement

• - Wastewater Ratio: Approximately 1:2 (clean water to wastewater) during operation.
• - Annual Filter Replacement: To maintain efficiency, replace the sediment and carbon filters annually.
• - Membrane Replacement: Every 3 years (or sooner if filtration performance decreases).
• - By incorporating a reverse osmosis system into your homebrewing setup, you gain precise control over your water chemistry, ensuring optimal conditions for every batch of beer.
