Water (WR) Water Pollution Treatment in campus area Walailak University operates an advanced wastewater treatment system that is capable of handling all wastewater generated on campus. The system applies tertiary treatment, consisting of the following stages Figures: Wastewater Treatment Plant of Walailak University. Figures: Map of Wastewater Sources within Walailak University (Walailak University, Thailand). Figures: Wastewater Treatment System of Walailak University.Preliminary and Primary Treatment (Screen & Sump Pump): Fine screens with automated brushes remove solid waste, while sump pumps transfer wastewater to aeration ponds.Secondary Treatment (Aerated Lagoon): A 5-meter-deep aerated lagoon equipped with vertical surface aerators ensures thorough oxygenation, enabling bacteria to degrade organic matter effectively.Stabilization Ponds (Facultative Pond and Maturation Pond): Facultative ponds (approx.2 meters deep) allow aerobic processes and sunlight penetration, supporting further stabilization of organic matter.

Water (WR) Water Pollution Prevention in campus area 1. Hazardous Waste Management from University LaboratoriesThe university has implemented a systematic process for managing hazardous laboratory waste to prevent environmental contamination, particularly of water resources. Waste is first classified and documented by type and source, followed by an assessment of concentration levels and hazard characteristics. It is then safely stored and segregated to prevent leakage or cross-contamination. The waste is collected and transferred to the university’s central storage facility, where it is handled in accordance with strict safety protocols. It is then disposed of by licensed contractors authorized by government agencies, ensuring compliance with environmental standards. Figures: Hazardous Waste Management from University Laboratories.
