Drinking Water Treatment

Increasing a scarce resource……………

About a hundred years ago the current programme of water purification (the filtration and chlorination of drinking water) began in the developed world.  Prior to that, the water coming from our rivers and boreholes presented a major health risk to both small and large communities.  Thousands of people died annually, killed by water-borne agents of cholera, typhoid fever, dysentery and hepatitis A.

Currently the World Health Organisation estimates that 1.2 billion people still lack access to safe drinking water with approximately 3.4 million (mostly children) dying every year from water related diseases.  These diseases are caused by bacteria, viruses and parasitic protozoa

Bacteria and viruses contaminate both ground and surface water and while the developed world has largely conquered water-borne pathogens, the developing world has not.  The Flash Doser provides a cost-effective, efficient chlorine dosing system that is simple to transport, install and operate.  It is able to automatically provide consistent batches of chlorinated drinking water that meet the World Health Organisation guideline value which is 5 mg/litre for drinking water. Minimum operator involvement is required for the Flash Doser to be incorporated into a sustainable system of rural water provision.

Access to drinking water that is clean is a basic right and safe water supplies, hygienic sanitation and effective water management programs are fundamental to human health. The need for uninterrupted, reliable and trustworthy water supplies is reaching alarming levels. This urgency is felt whether it involves water disinfection at municipal water treatment plants which service the metropolitan areas or smaller rural areas supplied from boreholes and other water sources.

Surface and underground water sources can contain harmful contaminants and micro-organisms. These must be removed from the water in order to achieve a water quality that is fit for use. Treating these water sources also aids in preserving water system infrastructure.

The World Health Organization recognizes that products containing chlorine are an effective water treatment method. Whether sanitation is needed in urban or rural areas, granular chlorine tackles this task: should it be the need to sanitize water in reservoirs, dams, storage tanks, boreholes or other isolated water sources i.e. municipalities with contamination problems, rural hotels and resorts, farming operations and emergency water provision after floods etc.

The Flash Doser can be used to automatically sanitise contaminated drinking water in the following situations:

  • Ground water
  • Rivers
  • Dams
  • Small Municipalities with contamination problems
  • Emergency water provision after floods etc.
  • Rural Hotels and Resorts
  • Farming operations.
