Whether it’s remediating groundwater at farms, purifying rinsing waters from food processing, or treating wastewater from pesticide manufacturing, Desotec has a simple and sustainable answer. Our mobile filtration solutions decontaminates wastewater from adsorbable organic halides (AOX), chemical oxygen demand (COD), and biological oxygen demand (BOD), allowing for its safe discharge or reuse.
Why treat pesticides in wastewater?
About 450 pesticides are approved for use in the EU. They contain organic molecules from several chemical families, e.g., glyphosate from phosphonic acid and atrazine from triazine.
Many of these molecules are known to require treatment on environmental grounds. Their chemistry ranges from being very acidic to alkaline. You have AOX including chlorinated, fluorinated, or toxic compounds that must be removed to protect aquatic life and the human food chain. Together, these compounds may be measured as COD or BOD. Their removal is essential to keep waterways aerated and healthy.
Desotec’s mobile activated carbon filtration solutions provide simple and sustainable answers to all these issues, ensuring that water is safe for discharge or reuse.
Surface water and groundwater remediation for pesticides
Desotec’s mobile filters are easy to use on farms. Their small footprint makes them ideal for busy agricultural sites, while their simple technology means they do not require operators in situ.
Pesticides are found in waters resulting from rinsing tools and machinery. This wastewater may be pooled and passed over the filters. Unlike many alternative technologies, activated carbon is suitable for batch treatments. Once treated by activated carbon, the water is safe for industrial reuse (e.g., washing or cooling equipment). Alternatively, it can also be discharged to the environment or sent to wastewater treatment plants (WWTPs) for further purification .
Where pesticides have entered the groundwater through rainfall run-off or by seeping into the soil, remediation is required. Groundwater is pumped up and passed through the filters before being returned to the land. As Desotec filters are mobile, they are well suited to both long-term and temporary applications, e.g., where spills have occurred.
Industrial wastewater treatment for pesticides
Rinsing waters from manufacturing may contain high concentrations of pesticides. In food processing, wastewater from rinsing fruit and vegetables may also contain traces of pesticides. Failing to reduce the pesticides load before sending wastewater to WWTPs would kill off the bacteria used in biofilters. Desotec filters provide effective pre-treatment, allowing for safe discharge of the wastewater to the sewer. It may also be possible to reuse it, boosting sustainability and driving down customers’ costs.
Pesticides are essential for plant and animal health, thus securing our food supply. Desotec’s mobile activated carbon filters are ideal for wastewater treatment. They can purify rinsing water and groundwater in the agricultural sector, protecting your business, our environment, and the human food chain.
Helping you comply
The EU Water Framework Directive sets quality standards for surface and groundwater. These are regulated through national and regional legislation as well as COD, BOD, and AOX limits.
Municipal WWTPs also set acceptance limits for COD and AOX concentrations in wastewater.
In general, laws and WWTP limits are becoming ever stricter. By installing Desotec’s modular filtration solutions, you can future-proof your agricultural business today.
How we help you
Desotec sustainable mobile filtration solutions
For all your wastewater purification needs, Desotec provides simple full-service solutions. Activated carbon filtration is certified as the best available technology (BAT) for phytosanitary wastewater.
Our filters are mobile and modular, so filtration set-ups may be adapted to meet changing demands or legislation. Filter exchange is swift and easy, requiring no production downtime.
Pesticides may be toxic, so it is essential to prevent workers exposure. Desotec filters are closed units. Once the carbon is saturated, filters are transported away from customers’ sites to our facilities. Most pesticides-filled carbon can be reactivated, making this a cost-effective and sustainable solution.
Desotec filters have been very effective in purifying our wastewater. Thanks to this simple but effective set-up, we’re now in compliance with environmental limits.
