Different Methods of Groundwater Remediation
Groundwater remediation is essential in a wide range of businesses, from drinking water extraction to mining. It’s hugely important to have the best water treatment system in place to help. Here are a few different methods that are used in water remediation that you may need to incorporate into your plan.
Water purification starts on a physical level, with the removal of the largest particles and obstructions that plague the water you are treating. Air sparging is one physical remediation method that’s used, which involves using pressurized air to strip water clean. A more common method is to pump water directly, with filters stripping away and large gravel or rock materials, and then letting the water be further filtered biologically or chemically to ensure that it’s in the best shape.
What makes a biological remediation method legitimate is that it utilizes microorganisms. These little helpers help through bioventing, biosparging, or bioaugmentation. In biological water remediation, biologic materials help to break down unwanted chemicals that aren’t easily separated from the water, particularly in industrial waste that forms in groundwater. A plus side to this method is that physically pumping groundwater out is not required to treat it.
This is most costly type of water purification, and it can also take the longest to accomplish. Chemical remediation can be achieved through a variety of methods, including carbon absorption, ion exchange, oxidation, and chemical precipitation. Chemical remediation is often used alongside physical water treatment to achieve the best results, and can help achieve the cleanest groundwater after the fact.
Ozone and UV Light
Some more distinct methods of remediation involve the use of either ozone or ultraviolet light. Exposure to these substances helps purify water differently, but both are used with the intention of killing any unwanted microorganisms. Those organisms can then be filtered out, and the water left that much healthier and purer than previously. These types of remediation serve as proof of how contaminated water treatment is much more than pressurizing water through a filter—although that’s certainly part of it. Microorganisms are some of the more difficult things to treat in a clean way, but the use of UV light and ozone help you to avoid harsher chemicals in your treatment system and, instead, embrace a more natural route.
Groundwater treatment is as diverse as the groundwater systems that exist in the world. There are some basic commonalities, like the existence of clay or sand in parts of the soil. Region and location can have an impact on the prevalence of specific physical, biological, and chemical contaminants that you need to consider how best to treat. It is meant to be strategic. Treatment goals help you to identify the right tools to meet your needs, and it can result in achieving a higher quality of remediation results, faster.
Know Your Needs
Groundwater remediation is relevant to a wide range of industries, and the better you understand it, the more likely you are to find the best water treatment system to suit your needs. Most instances call for a balancing of multiple methods and techniques, depending on what contaminants you’re treating and for what purpose.
