Sewage Treatment
Wastewater monitoring and treatment — protecting campus water quality before discharge to the environment
Target 2020
100%
Wastewater quality from all buildings within industrial wastewater standard.
Current Status (2025)
100%
All buildings and natural water resources meet industrial wastewater standard before discharge.
Wastewater Monitoring & Treatment
Wastewater monitoring and treatment are part of KMUTT’s water conservation policy, directly related to the safety and health of students and staff. The university is committed to preventing water pollution and ensuring effluent meets standards before discharge to the environment.
The wastewater monitoring program follows guidelines from Thailand’s Pollution Control Department, aligned with the Enhancement and Conservation of the National Environmental Quality Act B.E. 2535. Wastewater sampling from all buildings and natural ponds / water resources within KMUTT is performed monthly and analyzed according to standard methods by the Central Laboratory Services, Department of Environmental Engineering, Faculty of Engineering.
At KMUTT, qualitative and quantitative measurements are conducted regularly to monitor water quality from both pumping stations and final effluent buildings. More than 13 sampling locations are provided for continuous water quality monitoring across campus.
Wastewater Monitoring Parameters
Key parameters analyzed during monthly wastewater sampling across campus pumping stations and final effluent buildings.
pH
A measure of how acidic or basic water is. The range goes from 0 to 14. Standard: 5 – 9
SS (Suspended Solids)
Small solid particles that remain in suspension in water as a colloid. Standard: 30 mg/L
TKN (Total Kjeldahl Nitrogen)
Used to measure organic nitrogen and ammonia from urease and manure. Standard: 35 mg/L
BOD (Biochemical Oxygen Demand)
Dissolved oxygen needed by aerobic organisms to break down organic material in a water sample at a given temperature over a specific time period. Standard: 20 mg/L
TDS (Total Dissolved Solids)
Measurement of all inorganic and organic substances dissolved in water.
Sulfide
Produced by bacterial degradation of organic matter through sulfate reduction reactions in wastewater.
Fat, Oil & Grease
The amount of oil and fat in various forms contaminated in wastewater. Standard: 20 mg/L
After the lab supervisor reviews the accuracy of analytical and quality control results, the document is certified before publication via the KMUTT Sustainability website and yearly reports.
Campus Wastewater Facilities
Pumping stations, treatment systems, and monitoring activities across KMUTT.
