Pesticide Removal

Pesticides can be found at microgram levels in ground water or surface water. They usually come from intensive agricultural activities.

The most common pesticides found in water are Atrazine, DDT, lindane, Carbofuran, etc...

In natural waters, pesticides are present at ppb (microgram/L) level. Most of them are hydrophobic and easily removed by adsorption on activated carbon filters.

In case of large amounts or large plant capacities, nanofiltration can be a better adapted technology, avoiding hassle of media replacement.

Lenntech can provide tailor made skid mounted or turnkey pesticide removal plant.
