Water
Operation of Wastewater Treatment Plants and Tertiary Treatment
A programme in operating sewage treatment plants and controlling their processes: preliminary and primary treatment, controlling the activated sludge process with operating tests, nutrient removal, and tertiary treatment and disinfection to bring treated water to the quality required for reuse.

Objectives
Training outcomes
- Operate and monitor preliminary, primary and secondary treatment units.
- Control the activated sludge process with operating tests: food-to-microorganism ratio (F/M), sludge age, MLSS and MLVSS, the settling test (SV30) and the sludge volume index (SVI).
- Diagnose and correct bulking, foaming and poor settling.
- Operate tertiary treatment units: filtration, membranes, and disinfection with chlorine and ultraviolet light.
- Monitor treated water quality and its compliance with discharge and reuse requirements.
Content
What the programme covers
Day 1: wastewater and the first treatment stages
- Characteristics of incoming sewage and their variation, and the main parameters: BOD, COD, TSS, nitrogen and phosphorus.
- Preliminary treatment: screens and grit and grease removal; primary treatment: sedimentation tanks and the removal of sludge and scum.
Day 2: controlling the activated sludge process
- Aeration tanks, dissolved oxygen and aeration systems, and return and waste activated sludge.
- Operating tests and their calculations: F/M, sludge age, MLSS and MLVSS, the SV30 test and the SVI, with calculation exercises.
Day 3: nutrients and operating problems
- Nitrification and denitrification, and biological and chemical phosphorus removal.
- Filamentous bulking, foaming, poor settling and rising sludge, operating secondary clarifiers, and reading the microscopic examination of sludge.
Day 4: tertiary treatment and disinfection
- Sand and disc filtration, ultrafiltration, and membrane bioreactors.
- Chlorine disinfection and the concentration-time (CT) concept, ultraviolet disinfection, and dechlorination before discharge.
Day 5: quality, records and safety
- Monitoring treated water: sampling points and frequency, and discharge and reuse requirements in Saudi Arabia.
- Operating logs and daily and monthly reports, and safety at sewage plants: hydrogen sulfide and confined spaces.
- An operating case study, followed by the assessment.
Who it is for
Target audience
Operators, supervisors and engineers of sewage treatment plants, and chemists in the laboratories of these plants.
Method
Delivery method
Lectures, calculation exercises on operating tests and on data from real plants, and case studies of operating problems. A walk-through of the organisation’s plant and operating tests in the plant laboratory can be added. In Arabic or English.
Questions
FAQ
How does this programme differ from Drinking Water and Wastewater Treatment Technologies?
The technologies programme compares treatment methods and presents their applications; this programme is for daily operation and process control at a sewage plant through tests and calculations, together with tertiary treatment.
Can the operating tests be done in practice?
Yes. When the programme is delivered at the organisation’s plant, tests such as SV30 and suspended solids are carried out in the plant laboratory on its own samples.
Is there a certificate?
Every participant who attends the programme and passes the assessment receives a certificate of completion from Technology Experts Training Center, licensed by the Technical and Vocational Training Corporation.
A programme tailored to your organisation
The duration and topics of the programme are adjusted to the organisation's needs, and it is delivered at its site, in a training hall arranged by the Center, or virtually.
