6.25 m³/h Oily Wastewater Treatment Project — Port Refinery, Malaysia
An industrial effluent treatment system (IETS) for oily, CPI grease wastewater, delivered as a complete physicochemical + biological package — system integration, on-site commissioning and operation optimisation.
The treatment area at the Malaysia port refinery site.
Project Overview
| Item | Detail |
Location |
Port refinery area, Malaysia — petroleum refining |
Design capacity |
6.25 m³/h, continuous duty |
Wastewater type |
Oily / CPI grease wastewater; influent pH 6–7 (slightly acidic, neutralisation required) |
Treatment process |
pH neutralisation → DAF dissolved-air flotation → MBBR biological tanks ×2 → inclined-plate settler → clear water tank, with multimedia filtration and backwash |
Scope of supply |
System integration, on-site commissioning, operation optimisation and ongoing operational troubleshooting |
Client interface |
Process HMI diagram with PLC / Modbus address mapping, so the IETS status can be displayed in the client's main plant control system |
