How to size a professional reverse osmosis system
Reverse osmosis pushes water through a semi-permeable membrane that separates most dissolved salts. It is chosen when an application needs low and stable conductivity: espresso machines, combi-steam ovens, glass and dishwashing rinse, laboratories, humidification and some production processes.
Sizing starts from the daily volume of permeate and the peak draw. Production is rated at a reference temperature, often 15 °C: colder feedwater lowers output, so winter conditions must be taken into account. Feedwater salinity (TDS), hardness, iron and chlorine determine the pretreatment needed to protect the membranes.
Recovery is the share of feedwater that becomes permeate. A higher recovery saves water but concentrates salts on the membrane, so it is adjusted to the feedwater quality. On the Purecleer COMPACT ranges, recovery is adjustable up to 75% depending on feedwater and operating conditions.
Data to collect before sizing
- Required permeate volume per day and per hour, including the peak draw.
- Water analysis: TDS or conductivity, hardness, iron, manganese and free chlorine.
- Feedwater temperature range over the year and available inlet pressure.
- Target quality at the point of use, for example a conductivity range or remineralised water for coffee.
- Storage needs: direct-flow production or a buffer tank, and the number of draw points.
- Drain capacity for the concentrate and space for the frame and pretreatment.

Frequently asked questions about professional reverse osmosis
What conductivity does reverse osmosis achieve?
It depends on the feedwater. With a manufacturer-stated salt rejection of 99% on Purecleer membranes, permeate conductivity is a small fraction of the feedwater value. For coffee and cooking, the permeate is often blended or remineralised to reach a target mineral content.
Is a softener or filter needed before the reverse osmosis unit?
In most cases, yes. Hardness, iron and chlorine shorten membrane life. A softener and activated carbon filtration are usually installed upstream, selected from the water analysis.
Why does production drop in winter?
Membrane output falls as water temperature falls. Kinetico RO Compact outputs, for example, are rated at 15 °C; colder water produces less permeate, so the system is sized for the lowest expected temperature.
What happens to the concentrate?
The concentrate carries the separated salts to the drain. Its flow depends on the recovery setting: the Commercial 1000 DF, for example, produces 2.4 L/min of permeate for 1 L/min of reject water.
How often are membranes replaced?
Membrane life depends on pretreatment, feedwater quality and operating hours. Prefilters are replaced periodically, and membranes when production or salt rejection falls below the expected values; regular conductivity monitoring shows when to intervene.
