How do Wastewater Treatment Systems work?
Wastewater treatment systems bring the wastewater generated in production, hospitality, healthcare and communal living facilities within the legal discharge limits before it is released to the sewer or a receiving water body. For discharge to a receiving body, the sectoral standards of the Turkish Water Pollution Control Regulation apply; for discharge to the sewer, the limits of the relevant municipality or water and sewerage authority apply. Meeting these limits is the legal obligation of the business; non-compliance carries the risk of administrative fines and suspension of operations under Environmental Law No. 2872.
We always start the design with the characterisation of the wastewater: flow rate, COD, BOD, suspended solids, oil and grease, pH and, where the sector requires it, heavy metal values are measured. Next, the destination of the discharge and the limit values that must be met for your sector are determined, and the system is sized for this target.
For domestic-type wastewater, biological treatment is usually sufficient; MBR, MBBR or extended aeration activated sludge systems are selected according to the space constraints of the facility. For industrial wastewater, the pretreatment stage is decisive; equalisation, neutralisation, chemical precipitation and grease trap units protect the biological stage.
Meeting the limit once is not enough; the sample taken during an inspection must give the same result every day. Our systems are delivered with an automation infrastructure that can be monitored remotely, with flow, pH and level values tracked in real time. Sludge dewatering and disposal are also planned within the scope of the project. Reusing the treated water is a separate investment decision and is evaluated with greywater treatment systems.
