1 Introduction
1.1 Function and Application Area
PROGUARD Coffee is a non-electric system that combines several water treatment technologies. It
is designed for the desalination of potable water and its subsequent mineralisation for the production
of water of high sensory quality. The water thus produced is intended to be used as feed water for
coffee, espresso and hot drinks machines only. The targeted mineralisation allows the aroma of hot
drinks to fully develop. The previously performed desalination protects the hot drinks machine from
particles, limescale, gypsum and corrosion.

permeate and concentrate. Within the scope of PROGUARD Coffee, a semi-
permeable membrane is used that acts as a separator by allowing only water
molecules and gases like carbon dioxide to pass while retaining larger
molecules and ions. The RO-process is described in more detail in chapter 3.1:
How Reverse Osmosis Works in PROGUARD Coffee.
Raw water Water that is provided by the municipal water main (usually untreated drinking
water).
Permeate
The share of RO-treated water that passed through a semi-permeable membrane
is called permeate. The membrane of PROGUARD Coffee retains 97 % of
all salts in the water. Thus, permeate is very pure water that consists almost
exclusively of water molecules.
Concentrate
The share of RO-treated water that did not pass through a semi-permeable
membrane is called concentrate. In addition to the original salinity of the raw
water, concentrate also contains all those salts that have been retained by the
semi-permeable membrane.

add the desired type of minerals in the desired degree.
Water hardness The sum of calcium and magnesium ions in the water. These ions can cause
deposits like scale or gypsum.
Water hardness
types and other
salts
One can differentiate between two different types of water hardness:
Carbonate hardness and permanent hardness.
Carbonate
hardness
Depending on the amount, carbonate hardness, also known as
temporary hardness,
can cause limescale deposits (kettle rock)
Permanent
hardness
Depending on the amount, permanent hardness can cause
gypsum deposits
Total hardness Sum of carbonate hardness and permanent hardness
Non-hardness Apart from the total hardness, water also contains non-
hardness, mainly sodium chloride and sodium sulphate
Salt water Salt water contains a high share of non-hardness. It bears a much heightened
risk of corrosion and has an adverse impact on the taste of coffee products.

43
EN
Conductivity
The conductivity level is determined by the amount of all salts present in the water.
Together with the measured degree of carbonate hardness, it serves as a relatively
good indicator to determine whether the local raw water causes, if untreated, an
increased chance of corrosion in a downstream installed coffee machine.
TDS Indicates the sum of the dissolved solids (salts) in the water. The TDS value is
derived from the measured conductivity.
Mineralisation
Within the scope of the PROGUARD Coffee product concept, mineralisation
means the addition of the desired type of minerals (calcium hydrogen
carbonate) to the previously desalinated water. Depending on the local raw
water conditions, the mineralisation level can be customised to various
degrees, resulting in low, medium or highly mineralised water, each degree
with a different effect on the coffee taste.
App
The App makes a recommendation as to whether PROGUARD Coffee or
any other solution of the BRITA Professional Filter portfolio is the appropriate
product for the intended use. With regard to the installation of PROGUARD

3 General Product Information
3.1 How Reverse Osmosis Works in PROGUARD Coffee
PROGUARD Coffee uses the mains water pressure to force water molecules through a semi-permeable
membrane. The concentrate of PROGUARD Coffee with its concentrated amount of scale, gypsum,
sodium chloride and sodium sulphate will be released to the drain. The permeate however is nearly
free of ions and molecules other than water and carbon dioxide.
After being produced, the permeate gets mineralised afterwards to allow the coffee aroma to fully

Uses ion exchange technology to reduce the carbonate hardness of the raw water, thus preventing
scale deposits in the downstream equipment. During the ion exchange process, carbon dioxide is
formed in the water, resulting into the formation of carbonic acid. The properties of this carbonic
acid are later used to increase the amount of minerals that can be released from the mineralisation
cartridge PURITY C500 MinUp. The level of carbon dioxide can be varied by adjusting the bypass
