WASTEWATER MANAGEMENT
Wastewater management 6.1 Wastewater Power plant wastewater treatment system Will support waste water Total of approximately 1,700 cubic meters / day, divided into waste water from electricity generating system 1,500 m3 / day and waste water from employees and general activities 200 m3 / day. 6.1.1 Wastewater from the electricity generation process, totaling 1,500 m3 / day, originated from - Sedimentation tank of the water quality improvement system 95 m3 / day - Water Treatment system 110 cubic meters / day - Floor washing water 200 m3 / day - Plant Cycle Blow down 785 cubic meters / day - Service Water 300 cubic meters / day - Chemical Laboratory Drain 10 cubic meters / day
Some wastewater with pH not equal to 7 is sent for treatment by pH adjustment by neutralization system. As for the wastewater coming from various machinery and equipment Often contaminated with oil The treatment to remove oil and fat is performed by a wastewater treatment unit with a specific function of oil separator (Oil Separator). Will hire an outside company for further disposal.
Besides the wastewater that enters the wastewater treatment system of the power plant There is still some wastewater coming from the disposal of SO2 in the flue gas by the power plant using the Sea Water FGD system. This wastewater will pass into the aeration pond before draining into the sea.
6.1.2 Sewage from employees and general activities (Sewage) is approximately 200 cubic meters / day, which will be treated by Biological Wastewater Treatment Process to meet the wastewater standards of the Department of Industrial Works.
Rainwater that leaches the area inside the power plant
This section of wastewater will be collected separately from wastewater from other project activities. And dumped directly into the sea.
Wastewater from all power plants has been treated. The project will drain into the sea at the discharge point of the BLCP Power Plant (Sea Water Outfall), where the project's effluent system has a flow rate of approximately 62.3 cubic meters / second and a flow speed of 1.5 meters / second. The effluent quality meets the industrial effluent standards. The power plant has initiated a project to reuse treated wastewater in production and consumption processes such as watering plants to promote resource conservation.
