Introduction
The purpose of the Installation, Operation & Maintenance Manual is to give users a
reference for Technical Specifications, Connection Diagrams, Installation Procedures,
System Operation and System Maintenance of their BMB Technology Reverse Osmosis
System.
The essential information contained in this manual will allow the user to make full use of the
system. In the interest of brevity, an attempt has been made to include only that information
which will be used under normal operating circumstances. For special situations, it is
recommended that the user contact their authorized dealer or BMB Technology
(www.bmbtechnology.com).
Reverse Osmosis is the most advanced technology of water purification in use today. The
technique uses a nanotechnology enabled semipermeable membrane which can reduce or
remove most harmful impurities found in water including: microorganisms, nitrates, heavy
metals, insecticides and much more (see Figure 1 on page 3 for a comparison of different
filtration technologies).
Fig 2, on page 3 lists a more detailed filtration performance of specific materials. These
materials are only a partial list of the virtually hundreds of thousands of molecules that
Reverse Osmosis can filter out.
Osmosis is defined as the process of molecules passing through a semipermeable
membrane, from a less-concentrated solution to a more-concentrated solution. An example
of Osmosis is the roots of plants drawing water from the soil. Reverse osmosis is simply the
opposite of this process where molecules are forced through a semipermeable membrane to
form a less-concentrated solution.
Essentially, the Reverse Osmosis filter (RO membrane or RO element) has nano sized
pores that help remove microscopic contaminants from the incoming water (more-
concentrated solution) to produce better quality water (less-concentrated solution). An
illustration of this process can be found page 4, Figure 3.

There is a bit more to the Reverse Osmosis process as it pertains to Reverse Osmosis
systems, however, this will be explained in more detail in the upcoming sections.
This BMB Technology system harnesses the power of Reverse Osmosis to purify the
incoming water. It was specifically designed to enhance the Reverse Osmosis process by
using sensors, pumps, probes, minerals, software and other components. This system will
be mainly used in residential and commercial applications to reliably produce high quality
water.
This BMB Technology Reverse Osmosis system is one of the most technologically advanced
water filtration systems in the world. It incorporates state of the art filters, easy Plug & Play
components and Quick-Change Filter Technology (QCFT) for low maintenance cost.
The system also comes equipped with a digital controller with Smart Water capabilities. It
continuously analyzes the purified water and displays the results on screen. The system will
know when water is consumed and will automatically flush the reverse osmosis filters
afterwards to maintain water quality and extend filter lifetime. The system works in the
background to track water temperature, errors and filter lifetime in order to give the highest
up time possible while delivering the best water quality and user experience.
Some of the significant features of this product line are as follows:
• Elegant & compact design / LED light-up during operation
• Standing bracket, no mounting required, easy installation
• Locking quick change pre-filters for low maintenance cost

Reverse Osmosis Membrane –
Nova Pro + Biocera A-A Filtration process,
The most essential part of any Reverse Osmosis system is its filters. It is also a
misconception that all filters remove materials from the incoming water, some filters actually
add materials into water to improve the taste, increase the mineral content and other health
benefits. Although a Reverse Osmosis system can consist of many filters, they all fall into
one of three categories with each category having a very specific purpose:
• Pre-Filters
• Reverse Osmosis Membrane
• Post-Filters BIOCERA A-A , Antioxidant Alkaline

Pre-filtration before Reverse osmosis
The main purpose of the pre-filters is to protect the more expensive Reverse Osmosis
membrane filter from specific contaminants.
Traditional Reverse Osmosis systems have pre-filters which target sediment and chlorine as
they can damage the reverse osmosis filter and cause it to fail early. Additionally, traditional
systems have a significant health risk where although the filters are changed periodically, the
outside casing (housing) for these filters stay the same usually throughout the lifetime of the
system. This can result in unhygienic conditions as contaminants will accumulate on the
inside surface of the housing over time and can be gradually released into the incoming
water.
This BMB Nova Pro Reverse Osmosis System has three state-of-the-art pre-filters. The filter
element and housing are a single unit. Consequently, during filter replacement periods they
are changed at the same time in order to maintain system hygiene. Also, all of the pre filters
are easy to change and have a click-and-lock mechanism in order to reduce the risk of
leaks. Once the filter is being changed, simply keep twisting it into place slowly until a click is
heard. To remove the filter, turn and hold the lock to open position with one hand while
twisting the filter with the other hand until it is removed from the system.
Although the RO membrane filters used in this system are fully efficient in removing
microorganisms, the first and last pre-filters are equipped with Nano Zinc powder for
antibacterial effects. This prevents biofilm buildup on the membrane sheet surface which can
lead to fouling of the membrane filter. In addition to particles and chlorine, the pre-filters in
this system are designed to reduce heavy metals (iron, manganese and other rust), dust and
very fine particles down to 0.5 microns. This will allow the membrane filters to work with less
effort to produce high quality water. Please see the table below for a detailed list of the pre-
filters.

Reverse osmosis Membrane- filters 4 & 5 Total - 600 GPD
At the heart of every Reverse Osmosis system is the membrane filter’s. The membrane filter
consists of microporous, semipermeable membrane sheets. The sheets are glued to each
other around three edges with a thin spacer in between (prevents the sheets from sticking to
each other) to form a “leaf”. Next, depending on the desired capacity of the membrane filter,
multiple leaf’s with mesh spacers in between (to allow the water to pass between leaf’s) are
stacked on top of each other. The stack is then spirally wound with the open end of the leaf
adhered to a perforated tube that runs up and down the center.
The membrane is constructed in this manner because unlike the pre-filters which are
designed as “dead-end filtration”, Reverse Osmosis membranes are designed as “crossflow
filtration”. In dead-end filtration, the feed water is passed perpendicular to the filter surface in
order to trap large particles. However, in Crossflow filtration the feed water is passed
tangential to the filter surface so the more-concentrated solution (particles) exits at the end
of the filter while the less-concentrated solution (purified water) permeates through the
membrane surface, gets trapped between the sheets and exits out of the perforated tube.
Figure 4 below shows the difference between dead-end filtration and crossflow filtration.

Page 8of 44
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 through
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

The supply water requirements for this system can be found in
Table below.
If the water supply does not meet these requirements, the filter lifetime and output water
quality of the system can be affected. Please see section 7.1 for the recommended filter
lifetime of this system. This duration should be reduced depending on how much the water
quality exceeds the limits. Please also see section 7.2 on how to adjust the filter change
duration in the user interface.
If the feed water is supplied with raw well water, laboratory test of the water should be done
before installing the system. If there is a significant exceeding of these limits, a well water
treatment system at the source should be considered to correct the water quality.
The main components for this system can be found on the next page.

System on Board Water Ports
This system comes with four water ports on the side for easy installation and maintenance.
Since the system is wet tested after assembly, it is shipped with plugs on all of the ports in
order to prevent any potential leaking in the box from residue water that may be left after
testing. It is important to note that if the system does not require a tank, the plug on the
“Tank” connection should be left intact.
