Water is becoming a precious commodity around the world
Water is essential and cannot be replaced by anything else. Of the Earth’s water supply, only 2.5% is fresh water, which is not evenly distributed around the world. As a commodity, water is already a major international problems. In the future, the number of countries, in which fresh water is in short supply, will increase. This fact endangers everyone’s nutritional health. Predictably, as the demand for water increases, usage conflicts will break out. Approximately 260 river systems cross national borders, and 100 countries share 13 major rivers and seas.
Approximately 600 million people now live in 25 countries, where there is not enough water. Even in countries, where this precious commodity is available, the poor quality of the water often leads to life endangering illnesses. According to estimates from the World Health Organization (WHO), 1.2 billion people do not have access to potable water. The illnesses and death toll in developing countries is estimated to be around 80% due to contaminated water.
The Near and Middle East, as well as portions of Africa, are affected the most by water scarcity. In the future, the situation is likely to become worse, as the populations of these areas will double or triple in the next 50 years.
Most of the fresh water, approximately 70% of it, is used for agriculture. More than half of that is lost due to inefficient irrigation systems. While the world population has tripled in the last 70 years, water consumption has increased by a factor of 6 in the same time frame. Global water consumption may increase by as much as another 40% by the year 2025.
Water scarcity and failure around the world
Purification of Potable Water through Reverse Osmosis
Internationally, one of the major problems is contaminated drinking water. Drinking contaminated water can lead to infection and intoxication.
Water purification is understood to include any measures, which improve the water quality. The goal of water purification is the removal of contaminants. Hygiene is an additional goal of water purification, which should removed the undesirable germs from the water. Different procedures are used, each according to the quality of the water and the type of contaminant. These may include sieving, sedimentation, filtration, oxidation, deacidification, demineralization and disinfection.
Potable water purification equipment converts rivers, lakes and surface water into drinkable water, which corresponds to the strong guidelines of the World Health Organization. The core of the process is a membrane filter, which operates according to the physical principles of reverse osmosis. A plastic membrane works like a very fine sieve. Only water molecules pass through it. Viruses, pesticides, lime, heavy metals and even radioactive particles are retained.
All bacteria, at an average size of 0.001 mm, are approximately a thousand times larger than the miniscule pores. Thanks to this process, there is almost no need whatsoever for chemicals. This system is easy to operate. From time to time, consumable materials, such as chlorine, must be refilled.
The Mobile Water Purification Unit
The mobile water purification unit from German Expeditionary Camp, located in Berlin, is a tactical system for voluntary and independent usage when the water need is acute and permanent through the purification of brackish water in remote places. It can be used, for example, for the rehabilitation of salted wells in deserts or faraway arid places. It has been deployed throughout the entire region of the Mediterranean Sea. The water purification equipment can be self-sufficiently set up and operated off-road in cross-country trailers or specially equipped Defender land rovers, even in impassable areas.
Areas of usage:- Expeditionary and research camps
- Areas affected by floods and earthquakes
- Drought periods by agriculture
- Water failure due to high tourism
- Large events (gastronomy) without access to potable water
- Military conflicts and depressed area
