WeiZhi - Water Treatment Wastewater Treatment Equipment: Utilizing biological treatment technology, based on the operation experience of domestic and international domestic wastewater treatment facilities, combined with our scientific research achievements and engineering practice, it integrates the removal of BOD5, COD, and NH3-N into one unit. It boasts technical performance, excellent treatment effects, cost-effectiveness, automated operation, and convenient maintenance and operation. The methods for removing heavy metals from wastewater can generally be divided into two categories:
Method for Removing Heavy Metals: Converts heavy metals in a dissolved state in wastewater into insoluble metal compounds or elements, then removes them from the wastewater through precipitation and floating. Applicable methods include neutralization precipitation, sulfide precipitation, floating separation, electrolytic precipitation (or floating), diaphragm electrolysis, and other wastewater treatment methods.
Method Two for Heavy Metal Removal: Concentrate and separate heavy metals from wastewater without altering their chemical form. Applicable methods include reverse osmosis, electro dialysis, evaporation, and ion exchange. These wastewater treatment methods should be used individually or in combination based on the wastewater quality and volume.
