Conventional Water and Wastewater Treatment Systems
At VATEK Environmental Technologies, we believe that access to clean water is a fundamental human right. Guided by this vision, we design conventional water and wastewater treatment systems that deliver reliable, sustainable, and cost effective solutions.
Conventional treatment systems ensure that drinking water, process water, and municipal or industrial wastewater are treated in compliance with national and international standards. These systems integrate physical, chemical, and biological processes, offering proven and dependable solutions that have been successfully applied worldwide for decades.
Thanks to these solutions, waters from diverse sources and characteristics (groundwater, surface water, rivers, lakes, seas, as well as municipal and industrial wastewater) can be safely treated. This enables:
- Safe and healthy drinking water supply,
- Process water prepared to meet specific industrial quality requirements,
- Wastewater discharged without harming the environment or recovered for reuse.
Key Features of Conventional Systems
- Proven Technology: Processes that have been successfully applied worldwide for many years and matured through field experience. Performance is predictable, ensuring stable water quality even under seasonal fluctuations and varying loads.
- Flexible Design: Tailored according to wide flow ranges and varying raw water qualities. Easily scalable with modular structures when needed; dosing, retention times, and operational strategies can be quickly adapted.
- High Treatment Efficiency: Primary, secondary, and advanced treatment stages are intelligently combined to achieve targeted standards. High removal efficiency is ensured for color, turbidity, organic matter, and critical nutrients including nitrogen and phosphorus.
- Operational Reliability: Use of standard equipment allows fast commissioning and easy maintenance. Automation and remote monitoring options provide rapid response to failures, while consumable usage is tracked to optimize operational expenditures (OPEX).
Operating Principle and Process Stages
Conventional treatment processes vary depending on the raw water source and the targeted effluent quality.
Water Intake & Pre-Treatment: Intake structure, coarse/fine screens, grit and grease trap, equalization basin, pre-oxidation/aeration, pumping, chemical dosing.
Physicochemical Processes & Primary Separation: pH adjustment, coagulation flocculation, rapid/slow mixing, sedimentation (circular/lamella), DAF, softening, metal removal, color and odor removal.
Filtration: Rapid sand/multimedia filters, activated carbon, Fe–Mn filters.
Biological Treatment: Activated sludge, SBR, MBBR, nitrification denitrification, chemical phosphorus removal.
Secondary Clarification: Final settling, sludge return, excess sludge removal.
Tertiary / Advanced Treatment: Polishing filtration (sand/disc/deep-bed), membrane processes (UF/NF/RO), AOP (ozone, UV/H₂O₂), remineralization.
Disinfection: Chlorine, chlorine dioxide, UV, ozone.
Sludge Line: Thickening (gravity/DAF), dewatering (belt press, plate filter press, centrifuge), drying, polymer preparation, odor control.
Auxiliary Systems: Automation & SCADA, online monitoring (pH, turbidity, residual chlorine, ammonia, nitrate), chemical preparation and dosing, blower/pump.
Note: In industrial wastewater treatment, significant variations may occur depending on the source of the effluent; therefore, each plant is uniquely designed.
Our Application Areas
- Municipal Drinking Water Treatment Plants
- Municipal Wastewater Treatment Plants
- Industrial Facilities (textile, food, chemical, metal, energy, etc.)
For each project, a stepwise treatment process is designed based on the characteristics of the raw water and the targeted effluent values.
With our life cycle oriented engineering approach, we enhance energy efficiency, reduce chemical and consumable usage, and optimize sludge disposal costs.
Thanks to our advanced automation and SCADA infrastructure, our systems ensure operational continuity with remote monitoring, alarm management, and reporting features.
In our delivery models, we offer flexible solutions tailored to project needs:
- For high flow projects, basin based conventional treatment systems,
- For scenarios requiring rapid commissioning, modular and package type water treatment systems that provide scalable alternatives.
