LifeStraw© is a simple but very capable answer to the critical question of how to provide safe water interventions for personal, military or preventative use. It can guard against waterborne diseases such as typhoid, cholera, dysentery and diarrhoea, and provides for clean drinking water to be accessed anywhere there are water sources available such as rivers, lakes, ponds and even puddles. As a mobile water purifier, LifeStraw© is designed to turn fresh water into safe drinking water. The purifier effectively removes over 99.99% of waterborne bacteria, and 99% of the waterborne viruses responsible for causing common diarrhoeal diseases. It requires no power-source or spare parts and can be easily carried for simple access to safe and clean water. LifeStraw© contains a specially developed halogenated resin which kills bacteria and viruses on contact. A special chamber further increases the exposure of micro-organisms to the halogenated resin, thus enhancing the killing effect. Micro-filters are used to remove all particles down to 25 microns. Activated carbon absorbs residual iodine also improving the taste of water. The filtration lifeline of LifeStraw© is a minimum of 1000 litres. The only maintenance required to help stop the filters becoming blocked is regular backwashing. This is achieved by simply blowing air through the device. LifeStraw© offers reliable and easy access to safe drinking water, whatever the circumstances. visit our new Oil & Gas energy saving products at . . . http://www.drag-reducer.com Drag Reducer Chemical Supplier and Application Specialists Drag Reducing Agents (DRA) or Drag Reducers (DR) are chemical agents used to reduce frictional pressure loss caused by turbulence in pipelines."
