Pesticides are widely used in the agricultural industry to protect crops against insects, weeds, fungi and other pests. They either protect or increase yields, allowing crops to be grown on the same land more times per year. Along with the agricultural industry they are also used to control household weeds, reduce swarms of insects near roads and public parks, and save lives by managing mosquito numbers to reduce malaria and dengue fever cases.
There are hundreds of pesticides used for different reasons and they can have a range of toxicological effects. Pesticides can leach through soil into the groundwater or run off into surface water, causing widespread and harmful damage to the environment, humans, and wildlife. When growing crops, pesticides can also bio-accumulate in produce, potentially being toxic to humans.
Pesticides are usually removed from water using membrane methods such as reverse osmosis (RO), granulated activated carbon (GAC) filters, or through ion exchange. The treatment method chosen will depend on a range of factors, commonly the feed and product water specifications, and cost.
Our CIF® (continuous ionic filtration) technology combines continuous ion exchange and physical filtration into a single process. Using a carefully selected ion exchange resin, pesticides can be removed from most wastewater streams. CIF® is a robust process where pre-treatment usually isn’t required, and it can be used to target a range of different impurities.
Our EVAPX™ evaporation and crystallisation technology can treat the highly concentrated brine from reverse osmosis to provide a zero liquid discharge (ZLD) solution for power plants. Using the power plant’s waste heat as a part of the evaporation process can cause a high reduction of the operational cost of this solution.
