SPRO-300 Reverse Osmosis System - Commercial Use
Contact usFrequently Bought Together
The SRO300 Reverse Osmosis (RO) system is a compact freestanding module capable of producing up to 700 litres of deionised water a day. RO is an extremely efficient method of converting tap water into demineralised water, a combination of post filtration cartridges can further produce High Priority or Ultrapure water for laboratory and other uses.
A low-cost mid-capacity solution, the SRO300 is a modular unit, mounted on a tubular steel frame, making it easy to transport and site in just about any working environment.
This particular model can be used for a wide variety of applications, including the replacement of expensive ion-exchange fed appliance filters such as those used with Steam Ovens and Commercial Coffee Machines. The annual running costs for an RO system is around £150 per year in replacement cartridges vs £450 for market leading ion-exchange systems.
Reverse Osmosis water is as close to pure water as you are likely to produce without resorting to distillation which is considerably more expensive to operate. The typical removal rate for all contaminants is in excess of 90% - including those which are not removed via standard filtration such as Fluoride, Nitrates and Scale forming minerals.
Whilst this is a pumped direct flow system, and as such is ideal for feeding a drinking water faucet or cooler, for industrial processes where 'peak' demand may exceed the operating capacity of the unit, a pressure vessel may be installed to give a reserve supply.

FEED WATER REQUIREMENTS
Water Feed Temperature: 4º C to 25º C
Water Feed Pressure: 4-7 bar (60psi-100psi)
Chlorine: <0.1mg/1
Dissolved Iron: <0.2mg/1
Feed pH: 3 to 11
Max Silt Density Index: 5.0 (15 min)
Max Feed Turbidity: 1.0 NTU
Max Feed Conductivity: 500 ppm (approx. 1000uS/cm)
NB - mains water usually meets these requirements after pre-filter treatment.
* Based on a water temperature of 16º C at a pressure of 60 psi. Lower temperature and pressure will reduce the production rate.
Reverse Osmosis membranes reject approximately 90-95% of the Total Dissolved Solids (TDS), mains water with a conductivity of say 600uS should therefore yield a product water of around 30uS to 60uS. Higher quality water is achieved by post filtration cartridges which can reduce conductivity to virtually zero and achieve a mechanical filtration of 0.2 micron absolute. UV can also be added as a post filtration stage to ensure sterility - please call for details where a specific water quality is required.
