The controlled application of pesticides and herbicides is the foundation of modern agriculture, including organic agriculture. Herbicides and pesticides are typically only employed by organic farmers as a last resort, and they are typically concentrated versions of naturally occurring compounds that, when concentrated, can be used as pesticides.
This article describes the problems and explores your options, if you need to treat agrochemical effluent because there are pesticides in your groundwater. Continue reading for the safe removal of pesticides from your groundwater.
Currently used fertilizers and pesticides in farming
Herbicides, pesticides, and fertilizers, however, are taken into account in the farming business as a whole, to guarantee that the arable land they manage is as productive as possible.
It's been this way for a long time, and generally speaking, rules that are fundamentally pragmatic have made sure that hazardous or useless substances are removed, and new goods are adequately tested before approval.
Contamination caused by old agrochemicals
It wasn't always that many 'wonder-products' in the past that were eagerly advertised over the fields, later turned out to be hazardous or had unanticipated side-effects.
These non-biodegradable agrochemicals are steadily contaminating numerous neighbouring waterways, with their residue. This will continue for many years because of how they enter the sea. The legacy items in question, all of which are already restricted or outlawed, included numerous varieties of insecticides and herbicides, basically, any organic chemical.
Contaminants in waterways
Many pesticides and herbicides contained active chemicals that were intended to alter, the physiology of the infestations they were meant, to manage. Because, they are not naturally biodegradable, they can remain in the ground for a very long time.
They eventually infiltrate into groundwater and leachate through infiltration, and become insecticides. Inevitably, actively managed fields will facilitate this slow run-off, and over time, undesirable refractory compounds will find their way into larger water courses, and subsequently rivers. It's critical that this is kept to a minimum because, if not, the issue of pollution caused by these recalcitrant substances would grow significantly.
How to treat pesticides or agrochemicals in groundwater?
When dealing with this kind of organics, traditional removal techniques like physical filtration, chemical dosing, or radiation (like ultraviolet/ozone) are frequently ineffective. These traditional COD-improving techniques, which are used to lower the concentrations of other undesirable chemicals in wastewater, typically call for assistance from advanced tertiary treatment technologies.
Effective recalcitrant compound removal from water
Removing refractory organic compounds from wastewater to below quantifiable levels was difficult, prior to the development of advanced technology.
Electrochemical oxidation for water purification of pesticides or agricultural chemicals
Electrochemical oxidation has been a tested method. OH hydroxyl radicals are produced using electricity in this process, which then oxidise the resistant substances. This method has decent removal rates but uses a lot of electricity, which again has a detrimental impact on a company's carbon footprint.
Furthermore, most oxidation-only systems do not remove trace chemicals very effectively, as is frequently the case with pesticides in groundwater.
Ozone for removal of pesticides from water
Finally, systems that oxidise using ozone can be highly successful, but they frequently take a lot of energy to produce the ozone, and there is always a chance that it could escape because ozone is caustic and causes breathing problems.
Water treatment for isolated areas
Netsol Water manufactures devices that use our special conductive media, to adsorb organics on a significant portion of its surface area. The pollutant is then targeted via electrochemistry, and it is oxidised after that.
The medium doesn't require recharging. Most of our operational reactors use significantly less energy than comparable electrochemical devices, and only require a 1% to 2% annual top-up. Due to the historical usage of now-banned pesticides and insecticides nearby, groundwater run-off has been demonstrated to contain alarmingly high agrochemical levels, making these equipment’s ideal for many remote municipal and local water treatment facilities.
Benefits of using our water/wastewater treatment facilities for the treatment of pesticides in groundwater
Our systems have a number of benefits over other water treatments, if you have a problem with resistant organics like agrochemicals in remote areas:
1: Less energy is used when adsorption and oxidation are combined.
2: The electric current used also regenerates the surface of our medium, requiring only a small amount of replenishment, typically between 1 and 2% every year.
3: Remote operation is possible due to its simple design and lack of moving parts.
4: No chemical dosage to worry about.
5: All pollutants are transformed to water and gas, which are evacuated, so there is no sludge to deal with.
6: Systems from Netsol need little upkeep, making them perfect for remote applications.
In many agricultural sectors, intensive farming will become the norm as the global population rises.So, in addition to the need to efficiently treat run-off water from new farming systems, which frequently occur in both urban and rural areas, the problem of treating leachate that has been negatively impacted by legacy chemicals, will also need to be addressed.
Netsol is now working on the water treatment requirements for innovative agricultural techniques, like vertical and hydroponic farming.Add to that the fact that, water is becoming increasingly scarce, with many industrial water users planning to discharge zero liquids in the future. This means that the water needs to be purified after each usage, and reused multiple times.
There has never been a more pressing need for efficient, environmentally responsible water treatment.We think that, especially when it comes to dealing with old agrochemicals, only Netsol’s innovative systems can provide the whole solution, for the removal of numerous difficult-to-treat chemicals and compounds.
