Recovery of nutrients from wastewater

Recovery of nutrients from wastewater is an efficient process to reduce the presence of nutrients, particularly ammonium and phosphate in the environment. By reducing nutrients disposed into the environment, the naturally occurring phenomenon of eutrophication could be slowed, and potential economic...
