Trunz Water Systems

The biggest challenge on our planet is providing people with access to clean drinking water. Lots of fresh water deposits contain disease-inducing substances, such as viruses, bacteria or chemicals. A fact that has profound consequences for the health of those people involved.

Trunz water systems has converted the vision of a simple self-sufficient water treatment system into practice. The mobile, independent water treatment and desalination systems are powered using integrated photo voltaics and wind generators. This means that there are virtually no boundaries to using this system anywhere in the world.

Decentralised water supply

Water shop concept: A socially responsible, environmentally sound and economically profitable business model

• providing access to clean drinking water and energy for an affordable price
• establishing sanitary installations in order to improve health conditions
• reducing poverty by establishing micro entrepreneurship and small-scale trade
• producing green energy to operate the water shop sustainably
• raising awareness for topics related to water, sanitation and health

The operation of water shops is already established in some areas and remarkable success has been achieved.

SOS water supply: A concept for drinking water supply within 72 hours after a natural disaster

• are we prepared in order to help in case of emergency?
• how do we act – without bureaucracy and immediately?
• why did it take more than a week until Haiti was served with clean water?
• how long can a human being survive without water?

The chance of survival of a human:

• without air approx. six minutes (without permanent damage)
• without water up to three days
• without food up to three weeks

Water treatment technology

Ultra filtration

• river water
• lake water
• well water  

The ultra filtration membrane removes organic contaminants, viruses, bacteria, cysts, etc. down to a size of 0.04 micron without requiring toxic chemical treatment. Ultra filtration works through a mechanical procedure. Raw water is filtered under pressure through a high-technology hollow fibre membrane. This process remains the natural minerals in the water.

Reverse osmosis

• sea water
• salted well water
• brackish water

In addition to removing salt the reverse osmosis technology removes all contaminants, viruses, bacteria, cysts etc. down to a size of 0.01 micron withouth requiring toxic chemical treatment. The reverse osmosis filtration technology is based on a multi-layer membrane which filters the water under high water pressure.
