In contrast to surface water streams or rivers, a factory may not be able to discharge wastes directly into a groundwater source.There are, however, a variety of additional ways in which waste could perhaps contaminate a groundwater source. Due to the porosity nature of soil, any liquid wastes and dissolved particles can seep through the dry, unsaturated layer and into an aquifer below.This is why; both municipalities and commercial enterprises place a high value on groundwater treatment using technologies, such as electrocoagulation.
Sources of groundwater contamination
Battery acid, paint, household cleansers, and other potentially hazardous materials, can all be found in the leachate from unlined landfill sites, which might enter groundwater sources. Groundwater can be contaminated in a similar way by leaking septic systems that contain human waste, or by storage tanks for gasoline, oil, and chemicals. To maintain the quality of their food, farms use nitrate-rich fertilizers and pesticide sprays.However, these pollutants may seep into a subterranean aquifer during periods of heavy rain.
What are the Advantages of EC for treating Groundwater?
For applications requiring drinking water and process water, groundwater is a crucial source. Therefore, pollutants from those sources have the potential to seriously increase maintenance costs for industrial systems, and to negatively impact human health, if they are not appropriately handled.
Groundwater has been treated using a wide range of methods, including biological, chemical, and physical processes. Each of these procedures has advantages and downsides that are acceptable.
Advantages of electrocoagulation for treating groundwater
In the paragraphs that follow, we'll go over advantages of using electrocoagulation (EC) as a groundwater treatment process.
· EC can handle a variety of contaminants
The porosity of soil makes groundwater vulnerable to contamination from a variety of sources. Due to the variety of sources, it may be contaminated by a wide range of substances and components. While, some pollutants come from natural sources, most of the more dangerous ones come from the leaching of man-made materials. Treatment of contaminated groundwater may be challenging due to the range of pollutants.
To eliminate or minimize the majority of them from this contaminated groundwater, a multistage sophisticated technique may be needed. Multiple types of pollutants can be reduced by EC in a single system. The best pH for those pollutants, the type of electrode, and the required reaction periods, all play a role in this.
· Low Price of EC systems
Depending on what needs to be treated and the procedure to be employed, treating groundwater can become fairly expensive. Every step of a process is expensive, from setup to operation through maintenance. For its ability to remove contaminants, electrocoagulation is one of the treatment procedures with the lowest related costs.
The method is quite straightforward and has almost no moving parts. Typically, the electrodes are made of metals that are affordable to purchase. Depending on the starting pH of the groundwater, it may not even be necessary to use any of the affordable pH correction chemicals. These systems make advantage of system automation, to promote ease of use with little operator interaction.
· EC is able to handle dissolved solids (TDS)
In groundwater, many of the pollutants are dissolved. Because, they are so small, these solids can be challenging to remove, but EC makes this much simpler. While, it cannot reduce some TDS constituents, it can lower others, like heavy metals and hard minerals.
· Low Formation of Sludge
Due to the addition of the chemicals that trigger the coagulation process, significant amounts of toxic solid sludge are created, during the chemical coagulation process. Electrocoagulation doesn't have a problem with this. EC systems don't need many, if any, dangerous chemical additives.
It occasionally requires additives; however, these are usually only used in modest doses to regulate pH. Additionally, the sludge might be safe enough to be used to organic fertilizer, as a soil supplement in agricultural applications. This benefit would lower the cost of sludge disposal.
Groundwater treatment doesn't have to be difficult, and specialist electrocoagulation technology, may play a role in a groundwater treatment application's ideal solution.
The advantages of EC groundwater treatment, for drinking water and process water, are well known to Netsol Water. As a result, we combine our electrocoagulation systems, to provide our municipal and industrial clients,cutting-edge and creative treatment solutions.
