As our most precious resource water is becoming more and more contamination through man made pollution, the increase and severity of disease, increase in the ozone layer, deforestation of rain forests. This is evident through the rapid yearly increase in water borne illness and diseases. Our scientists are working on ways to reverse this cycle through technologies and processes.
To help us understand what is available this section of the web is dedicated to an introduction to water and technologies available for water filtration and or purification
There are a large number of technologies that can be used to filter, sterilise and purify water to make it acceptable to drink. Many of these technologies have been around for many years. There new technologies and processes being introduced to further enhance the quality of water. With pollution, population growth, deforestation, water contamination is becoming a increasing problem across the globe.
Here are some of the main stream filtration, sterilization and purification processes;
• Micro Filtration
• Nano Filtration
• Iodine Disinfection
• Chlorine Disinfection
• Chlorine Dioxide Disinfection
• Ultra Violet light
• Reverse Osmosis
• Granulated Activated Carbon
• KDF Resin
• Solid Carbon Block
• Water Boiling
Each of these filtration, purification and/or sterilization processes have the can be effective to some degree and have a place for use in particular circumstances. Some of the methods remove bacteria, some also virus’s and some chemicals and pesticides.
When assessing the effectiveness of each of the process, there are many considerations need to be evaluated. This include the flow rate of the water of through the process (for example, in the ionization process, is there sufficient electrical polarization happening , the chemical concentrations required to destroy bacteria and cysts, the penetration of the technology into the water, for example, for UV purification, does the UV penetrate all the water passing by and for sufficient time.
