Agriculture | Reverse Osmosis & Water Treatment Systems

The importance of water for agricultural use cannot be overestimated, because it is this energy-intensive resource that drives food growth. Water not only is needed to grow crops, but is necessary to raise livestock for our meat products. There is a direct correlation between the amount of applied water in use within the agricultural sector and the amount of crops that is yield. 

Large amounts of subsidies in the agricultural sector, along with efficiency issues have made the goal of improving output while reducing water use a greater challenge. Agriculture still remains the greatest consumption of our water resources and the reality of diminishing water sources is a problem that the world continues to ignore for the most part. For that reason, our solution in creating high quality water treatment systems that will generate high quantities of freshwater from unsuitable locations, such as the ocean, rivers, lakes, wells, etc. has made tremendous progress in alleviating the stress from many industries, most of all agriculture.

The largest use of freshwater in the United States is for irrigation purposes. Much of this water is obtained from groundwater, which only has a limited supply. Each year, aquifers are exhausted of water or contaminated, making sources of fresh water for irrigation increasingly scarce. Farms around the world have started to utilize alternative methods for water conservation and protection of this precious natural resource. It is not a secret that reverse osmosis water treatment systems are utilized in cultivation houses for the latest plants in greenhouses or aquaculture growing. The vast majority of current professional growers rely upon these commercial agricultural water filters for the last several decades. We will list the benefits afforded by this technology to highlight its impact throughout the world:

  1. Environmental preservation
  2. Compliance with regulations
  3. Production consistency Water
  4. Conservation/Sustainability
  5. Cheaper price for water usage
  6. Water and sanitation sustainability
  7. Disinfection & Cleanliness
  8. Vendor consistency and preservation
  9. Tailor-made solutions
  10. Clean water for workers
  11. Purified drinking water for workers


Due to plants and vegetables already consisting of natural filtration means that allow for much more non-stringent agricultural water filtration requirements for irrigation. For this reason, irrigation has a greater fill of resources to utilize compared to scarce groundwater resources. Irrigation primarily relies on practices that depend on making reuses of grey water, in addition to treated sewage effluent (TSE). These practices create wastewater, which is seen as a terrible source for drinking water, but perfectly suited for irrigation and farming once undergoing a reverse osmosis system. Many farms have resorted to only using these effective tactics for their water, and completely eliminated the use of underground aquifers.

Almost all naturally occurring water contains some form of contaminants from the surrounding rocks and soil that make up the earths crust. Drained irrigation water and effluent sewage water are contributors to the quality of water. Typically, salinity level is the main concern in the irrigation industry due to the debilitating effect salt has on soil and product growth. However, there are also other contaminants like boron that can be just as harmful to the irrigation industry due its similar adverse effects. Elevated amounts of boron cause toxicity effects to occur which causes damage to the soil and overall product yield. These high amounts can already exist naturally in groundwater and seawater but can also be a result of contaminated water.

The following systems complement the applications of hydroponics, commercial farmers, greenhouses, and pharmaceutical industries. These systems also tackle the issues of bacteria & viruses, reduction of chloride, sulfate, sodium, nitrate, arsenic, and overall TDS.
