How to Minimize Water Pollution in Agriculture

The agricultural industry uses around 70% of the world's freshwater. This means that they have the most to worry about in terms of potential contamination risk at least when it comes to volume. Here are a few technologies that can be built to help reduce potential pollution issues in water in this industry.

Smart Monitoring Systems

The fact that the world is set to grow by 34 percent by the year 2050 means that the agricultural industry is going to need to expand by 70 percent to keep up with all the new people. In order to make sure that the water delivered to all of this new infrastructure is clean, and that it doesn't get contaminated anywhere along the way, new precision agricultural technologies are being used.

New WiFi technologies make it possible to measure a wealth of real-time information across large agricultural areas. This includes data about soil quality that water may be traveling through, as well as the quality of the water itself, and anything else that could potentially cause pollution in the water such as air quality.

Tainted water means tainted crops, so real-time measuring is essential for keeping the water clean in agriculture. This is especially the case in third world countries where there are a large number of potential extra contaminants from disease and unsafe dumping practices.

Wastewater Treatment

Since a large amount of water is needed to sustain crops to feed the world's population, it follows that there's also a lot of opportunity for waste. This waste water is often full of pesticides and other chemicals that are used to sustain the crops. Contaminants can include phosphorous and nitrogen as well as harmful bacteria from animal waste.

This is why water treatment is essential when it comes to wastewater coming from agricultural areas. Fortunately, wastewater such as sewage sludge can be recycled with new technologies. Not only will this prevent the agricultural process from pouring poison into local water tables, but it will also make agricultural practices more efficient.

This includes products that don't use biocides that are full of dangerous chemicals. For example, some of these technologies use ozone to destroy bacteria in wastewater and treat it for recycling purposes.

Some of these processes can handle 80 barrels of recycling per minute. Technologies like this can achieve this result by shunting water through multiple different zones of treatment. These treatments are twice as potent as chlorine for destroying bacteria. 

  • The first zone destroys bacteria.
  • The second zone can destroy iron and magnesium, which many bacteria life forms use for food.
  • The third zone uses acoustic sound waves to destroy microscopic bubbles that many microorganisms live in.
  • The last zone uses something called electrochemical oxidation to get rid of other pollutants like nitrogen.
