How Does Global Warming Affect Water Security

How Does Climate Change Affect Water Security?

Climate Change encompasses great threats in a wide aspect. From daily living, the quality of the air we breathe, aggravated natural disasters, food supply, even the water security of many nations. In fact, according to studies, water is the most affected life resource from climate change. One example is melting glaciers causing sea-level rise and flooding. Aside from that, it alters the natural cycle water undergoes.

The Water Cycle

If you remember the water cycle from primary school science, it is often shown as a diagram with three major processes necessary to produce water. These are evaporation, condensation and precipitation.

Since the top effect of climate change is warmer temperature, air can now hold more moisture during the first stage of the cycle – evaporation. This leads to a heavier accumulation of water resulting in heavier rainfall. With that, flooding, streamflow and surface runoff may occur and contaminate the water supply in any country. Fortunately, there are Australian water suppliers that can provide solutions.

Water Treatment Solutions

Since water is one of the most basic necessities of a humans’ life, an Australian supplier has to find ways to provide safe water for everyone. Various technologies are used to achieve water security for drinking, agriculture, and more.

1. Ultrafiltration

This technology involves a membrane separation process that eliminates suspended solids, bacteria, endotoxins and other pathogens. This process produces water with high purity and low silt density. To accomplish this, it uses hollow fibres of membrane material found flowing either inside the shell or in the lumen. Ultrafiltration is widely used for safely producing drinking water. In a complete water system, UF can be in conjunction with other technologies as well.

2. Reverse Osmosis

Reverse Osmosis is another water treatment technology that involves a membrane process. Only this time, it removes dissolved salts and other water impurities. It requires different membranes and designs to remove salt from everything. This technology is also called desalination which is commonly used in converting seawater and brackish groundwater into safe drinking water.

3. Dissolved Air Flotation

Commonly used to treat wastewaters, Dissolved Air Flotation is a water treatment process that involves the removal of solids, oil and grease. It is also used to treat wastewaters from shopping centers and industries such as manufacturing and poultry. To accomplish this, it requires a special dissolved air contactor that efficiently dissolves air in the recycling stream and releases it with the incoming wastewater stream. This process produces fine bubbles which float solids and impurities to the surface. This waste is then removed by a scraper system.

4.  PFAS Remediation System

PFAS uses our proudly patented technology that consists of a multi-stage process. This process removes more than 95% of both short and long-chain PFAS precursors. In addition to that, it also focuses on destroying PFAS contaminated by-products and regenerating the extraction medium which provides a complete solution. Moreover, it can also remove other possible contaminants existing such as pesticides, herbicides, hydrocarbons, and trichloroethene. PFAS Remediation System is ideal for reinjection, irrigation, and potable water grade.
