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

Some applications require a larger amount of water. Trunz Water Systems has developed independent and solar powered solutions for the supply of clean drinking water in remote villages. Depending on the raw water source or the contamination in the raw water, a Trunz independent water treatment plant for soft water or solar powered desalination system with an RO unit for brackish or saltwater will be installed.

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

Trunz Water Systems is targeting a next level with the water shop concept. This innovative solution is going one step further by using renewable energy and exceptionally energy efficient water treatment units to operate water shops in a sustainable and environmentally friendly way. The water shop concept is by far more than a technical solution – it is our vision to achieve maximum impact such as:

  • 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

More and more frequently natural disasters occur which deal out destruction and enormous damage. 2010, 15 strong earthquakes were counted worldwide. Sadly, most often they affect people who live in rather poor regions.

  • 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

To achieve a reliable and satisfying result, Trunz water systems includes field tested and experienced water treatment technologies. Depending on the raw water quality the water treatment systems are equipped with two different filtration technologies:

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.
