The membrane pores are so small that if the Reverse Osmosis filter was designed as dead -
end, the pores would be clogged up in a matter of few litres due to the abundant number of
dissolved solids found in the feed water and the extremely small membrane pore size.
The membrane filter has one water inlet and two exits. The feed water first travels throug h
the pre- filters and then to the membrane filter. At the exit of the membrane filter one of the
ports is the waste water (more-concentrated solution) which is connected to the drain, while
the other port is the purified water (less -concentrated solution) which is plumbed to the post-
filters. Figure 5 on page 9 shows a detailed schematic of the membrane filter.
BMB Technology Reverse Osmosis membranes are made of the highest quality Thin Film
Composite (TFC) polyamide and are designed to remove a wide variety of both aesthetic
and health related contaminants. Additionally, the following have been, considered when
designing the membrane filter:
• Average membrane pore size of 0.0005 m
• Ultra Low Pressure (ULP) membrane (min. 2 bar feed water pressure)
•
Included system pump for optimum osmotic pressure
