Agricultural Water Treatment
Agricultural water or farm water is water which is going to be used for farming. Typical sources for agricultural water are surface water (streams, rivers, dams and reservoirs), and groundwater (springs, wells and bore waters). Agriculture is by far the largest global user of water responsible for around 70% of global freshwater use.
Contamination of Source Water
Crop watering is a major user of water which requires contaminant concentration to be closely monitored. This is to ensure optimal growth of the crop and to ensure its quality. Crop watering with contaminated water can also cause environmental issues, with contaminants potentially leaching through the soil and into groundwater.
Contaminants also need to be monitored when water is being used to feed livestock, to ensure their health. Typically contaminant levels for livestock are between the acceptable levels for crop watering and human consumption, and different animals can tolerate different impurity levels.
Contamination of Discharged Water
Agricultural runoff water can contain a wide variety of pollutants typically as a result of the use of fertilizers, pesticides, and animal manure. Those pollutants typically include Nitrate, Ammonia, and Phosphate and general high organic pollution. Sometimes the run-off even includes synthetic hormones and antibiotics. Pesticides are sprayed on a range of crops to control pests and enhance production, and these chemicals can find their way into water supplies and require treatment.
Releasing contaminated water into lakes, rivers or streams can have a devastating effect on the local environment, potentially harming plants, fish, and other wildlife that come into contact with it and affecting the ability for local communities to use the water for drinking. Decades of high fertilizer use in some areas of the US has resulted in polluted groundwater making it unfit to drink without advanced treatment. sing contaminated water to grow crops can have a severe environmental impact, as water leaches into the soil and through to the groundwater.
Clean TeQ water has a number of technologies suitable for removing nutrients from agricultural run-off water. Our BIONEX™ technology is particularly suitable to reliably remove nitrate and ammonia from large volumes of run-off to below 1 part per billion, making it safe for re-use or discharge. Using this technology we can also remove Phospate, BOD and COD from run-off.
On the water supply side, we can provide agricultural users with low cost zero or minimum brine systems that remove salts from the water supply, thereby preventing soil degradation and ensuring the quality of crops or health of livestock.
