Industrial Effluent System for ED Coating Plant
Project Description: To construct a Wastewater Treatment Plant for a ED Coating plant, Pasir Gudang, Johor.
Product Used in this Project:
A company which is based in Ulu Tiram, Johor is providing ED coating services was required to treat their waste water based on DOE standard B. Their production process produces highly acidic waste containing Zinc, Iron and others as shown below
Wastewater Discharge characteristic and DOE Standard B Discharge Limit
The wastewater will be first go through the existing Degreaser Sump and Collection Sump before being transfer to the equalization tank where it will stored for homogenization of pH, concentration, temperature and flowrate of the raw effluent. The wastewater will then be transferred to the Reaction Tank by using the EQ Transfer Pump. In the Reduction Tank, the process of Chromium Hexavalent (Cr6+) to Chromium Trivalent (Cr3+) will take place so as the coagulation of suspended solids as well. The level of pH will also be adjusted accordingly by adding caustic soda.
pH Level Control Panel
Flocculation Tank
Aeration Tank
Buffer Tank
After the pH level have been stabilize, the effluent will then be transferred into the Flocculation Tank the fine flocs will be mixed with a polymer to create a bigger flocs which is easier to clarified through the use of gravity sedimentation via the use of Primary Clarifier. The clarified effluent is then transferred to a Buffer Tank which will then be pump into an Aeration Tank for biological process
Anti-Clog Lamella Clarifier
A Complete Mixed Aeration System (CMAS) is applied to provide a large dilution capacity shock and toxic loads handling. The dissloved organic content of the effluent would be remove via the fine membrane system and air blower aeration system which provides oxygen for bio-degradation process. After the effluent have been treated, its is then transferred into the Treated Water Tank before being moved to the Carbon Filter where any residual organic matters is removed and is ensured that it meets the DOE Standard B Discharge Limit. The treated water is then discharge in a public drain and the flowrate of discharge is monitored by a Flowmeter.
The sludge form the previous process will be collected in a cone sharp tank for thickening purposes which will then be fed into a filter press. This filter press will further de-water the sludge in order to achieve 25% dryness of sludge cake before disposing it to a DOE approved waste management center. The filtrate will be transferred to the front-end (Collection Sump) further re-processing.
