Removing Phosphates from Wastewater


We have approximately 180 ppm of phosphates in our plants discharge water. Our discharge stand is 10 ppm. Any easy way or process to treat these levels to or discharge standards?

Robert,

Bench test effluent after adding lime. You might have to acidify first, but try just adding some calcium (or magnesium) ions, mix and separate solids.
Should get most of it.
