electrocoagulation waste water treatment :

• Metals in the wastewater are usually found in their salt forms which lead to the fact that most of the metals are totally soluble in the liquid phase and are difficult to remove by simple filtration or other simple physical processes.
• The efficient process to remove dissolved metals is the coagulation process. The common coagulation is the chemical coagulation which is cost effective but has 3 main disadvantages; (a) the chemicals create a byproduct of the process – a secondary pollutant in the water; (b) the sludge percentage is relatively and (c) the process is highly pH depended.
• heavy-metal-process
• electrocoagulation technology, designed to handle hundreds of m3/h of water and overcomes the above disadvantages of the chemical coagulation. The electrocoagulation process consumes electrical and pure metal electrodes. The average power consumption per cube is around 0.1-0.5 Kw and the period between the replacement of electrodes ranges between 6 to 12 months.
• One of the advantages of electrocoagulation heavy metals removal process is its capability to change the metals’ form to a Hydroxide form that will settle immediately as a stable complex from the solution. The metals precipitate solids are removed in the form of sludge in the settling stage. The clean water can be reused for the mine’s needs or can be discharged back to the environment in a safe, authorized and ecological manner.
