Abstract


Hospital wastewater is a source of potential environmental contamination. Therefore, the waste water needs to be treated before it is discharged into the drainase. Various research methods have been used to treat hospital wastewater But some methods that have been implemented have not achieved the standards for hospitals that have been set by the government. The experiment was conducted by an electrochemical method which is electrocoagulation using aluminum electrodes with independent variable such as the voltage, contact time and concentration of electrolytes. The response is optimized using response surface with optimum conditions obtained: the contact time 34.26 min, voltage 12 V, concentration electrolyte 0.38 M with a decrease in the response which is COD 65.039% each. The model recommended by the response surface for the three variables is quadratic response.
