DATA SHEET BRO4

DAYLIFF BRO4 Reverse Osmosis water treatment plants are simplified specification versions of the well-established Dayliff DRO range specifically designed for removal of lighter concentrations of dissolved salts at lower cost. The heart of the system remains efficient low energy Dayliff membranes though control and component specifications are adapted for less arduous operating conditions with the plants being thoroughly engineered to provide reliability with the highest treated water standards. They offer the following features:-

• High efficiency low energy brackish water membranes housed in strong corrosion resistant GRP pressure vessels

• Pre filtration through sediment and carbon cartridge filters • High efficiency Dayliff Feed and Cleaning pump • Pump controller providing automatic operation with overload, over/under voltage and dry

running protection • Corrosion proof TPE-U high pressure piping • System monitoring instruments including flow meter and pressure gauges • Semi-automated plant operation including RO feed water flushing cycle and CIP facility • Compact skid mounted design for simple installation and transportation

All DAYLIFF RO plants are highly efficient, easy to operate and simple to maintain and offer the ideal solution for small and medium scale reverse osmosis requirements.

Solar power option is available on request.
