Precipitation/Heavy-Metal Precipitation

Heavy metals have an individual pH for precipitation. When reaching this pH, they are present as largely undissolved metal hydroxides.
In order to achieve very low residual concentrations of heavy metals, precipitation as metal sulfide is required. Heavy-metal precipitation by means of organic and inorganic sulfides is also used when complexing agents are present in the waste water. Moreover, anions such as phosphate or fluorides can be removed reliably from the waste water by means of specific precipitating agents. You can choose between an OKO-tech continuous process and a batch process for this purpose also.
