Our teams collaboratively define equipment footprints, access requirements, and utility connections. We design specialized vibration isolation foundations for critical machinery and integrate dedicated cable and pipe galleries within the civil structure, optimizing space and ensuring future maintainability. This holistic integration prevents last-minute structural modifications or expensive rerouting of services, leading to a highly functional and efficient plant from commissioning.
- Water-Retaining Structure Construction and Lining Systems:
- Significance: Basins, clarifiers, and tanks are the heart of any WWTP. Their watertight integrity and structural durability are paramount, directly impacting process efficiency, environmental protection, and operational costs.
- Technical Complexities: Achieving perfectly watertight concrete pours for large volumes, managing concrete shrinkage and cracking through precision joint design (expansion, contraction, construction joints), ensuring perfect adhesion and integrity of specialized lining systems (geomembranes, epoxy coatings) to concrete surfaces, and managing hydrostatic pressures on thin-walled structures.
- Athiras’s Approach: We employ advanced concrete technology for water-retaining structures, including optimized mix designs, rigorous curing protocols, and precise temperature control during pouring to minimize thermal cracking. Our detailing for joint placement and waterstops is meticulous, preventing future leaks. We have expertise in installing a variety of lining systems, ensuring superior bonding and long-term performance against aggressive chemicals or biological agents, validated through advanced non-destructive testing for watertightness.
- Process Flow and Hydraulic Structures Integration:
- Significance: The efficiency of a water/wastewater treatment plant fundamentally relies on precise hydraulic management. The civil structures (channels, weirs, sumps) must guide water flow accurately to optimize treatment processes.
- Technical Complexities: Designing civil structures with specific dimensions and slopes to achieve desired flow velocities and minimize turbulence, integrating mechanical equipment (e.g., screens, mixers) into civil structures without impeding flow, managing varying flow rates and their impact on hydraulic profiles, and ensuring structural stability against dynamic water forces.
- Athiras’s Approach: Our process engineers work in tandem with civil and structural teams from the earliest stages. We utilize Computational Fluid Dynamics (CFD) modeling to simulate water flow through proposed civil structures, optimizing channel dimensions, weir designs, and baffling systems for maximum hydraulic efficiency and minimum energy consumption.
