The document describes a water treatment system called WaterBox® that uses CarbonAdd® granules to produce clean drinking water from polluted sources. The system is compact, portable, easy to use and maintain, and can produce enough water to supply 2,000 people per day. It provides an affordable solution for producing drinking water in disaster areas and developing communities where clean water is scarce.

1. Quickly available solution for the
production of drinking water
Alzey, Germany, 2014

2. Initial situation
Fresh water is only available to a limited extent
Tap water is often polluted, e.g. by
chlorine
salt
heavy metals
etc.
Drinking water is already scarce and will be
even more every day.
Sometimes only untreated water is available
(river, lake, reservoir, well).
Polluted water may cause illnesses or even
worse epidemics.
Fresh water of high quality is a scarce good!

3. Our solution: WaterBox® and CarbonAdd®
Production of top quality drinking water using simple means.
Flexible quantities possible (from 24 cbm/d up to 100,000 cbm/d)
Water treated with the Carbon Add® method completely fulfills all
quality standards for drinking water.
Scientists of our partner Lavaris have developed a new compound,
CarbonAdd® to treat fresh water.

4. CarbonAdd ®
Pure inorganic multi-component buffering system
Consisting of reactive calcium salts, sodium hydrogen carbonate,
soda and calcite
Suitable for most water conditions
All ingredients occur in natural waters, are permitted for drinking
water conditioning

5. Drinking water ingredients
Calcium
Dietary mineral, most abundant element in the human body with
about 1.2 kg
Sodium
Compound of many foodstuffs (e.g. salt)
Necessary for humans to maintain the balance of the physical fluids
system; for nerve muscle functioning
Too much sodium can damage the kidneys and increases chances
of high blood pressure
Sodium is essential, but the amount required is controversially
discussed

6. Drinking water ingredients
Chloride
A chemical the human body needs for metabolism (turning food into
energy)
Also helps keep the body's acid-base balance
Amount of chloride in the blood is carefully controlled by the kidneys
Bicarbonate
An alkaline, vital component of the pH-buffering-system of the human
body (maintaining acid-base homeostasis)
70-75 % of CO2 in the body is converted into carbonic acid (H2CO3),
which can quickly turn into bicarbonate (HCO3)
Also regulates pH-value in the small intestine

It is scientifically proven that higher values of these elements are beneficial to human health
* Due to an unintentional overdose of CarbonAdd® during our pre-tests, these first results do not really display the expected
values. But actually that is just a matter of regulation.

8. Description of the WaterBox®
The new WaterBox ® is a highly compact water treatment system
whose innovation is the use of the patented CarbonAdd® process to
remove inorganic impurities.
The WaterBox ® makes it possible to produce clean drinking water
while being affordable for all.
The system is one of the smallest on the market and has been
developed specifically for disaster areas and for development
projects in consultation with UN-HABITAT.
One Water Box ® can supply
about 2,000 people with potable
drinking water, with a capacity
of 28,000 liters per day.
