Sludge management in waste stabilization ponds (WSPs) is essential for safeguarding the system performance. Sludge accumulation patterns in WSPs are strongly influenced by the pond hydrodynamics. CFD modeling was applied to study the relation between velocity profiles and sludge deposition during 10 years of operation of the Ucubamba WSP in Cuenca (Ecuador). One tracer experiment was performed and three sludge accumulation scenarios based on bathymetric surveys were simulated. A residence time…

The Role of Environmental Variables in Waste Stabilization Ponds' Morphodynamics

In management of helminth infections and transmission, the correct prediction of sludge accumulation patterns in waste stabilization ponds (WSP) is important as sedimented eggs are associated with

Sludge accumulation in stabilisation ponds in the Soudano–Sahelian climate of Burkina Faso

ABSTRACT Sludge accumulation in waste stabilisation ponds based on local conditions is of great interest for successful sludge management, and accurate accumulation data are essential for WSP design

Performance evaluation and spatial sludge distribution at facultative and maturation ponds treating wastewater from an international airport.

Overall, the ponds operated under very underloaded conditions and presented a satisfactory quality in terms of effluent concentrations for most parameters and showed similar or slightly lower concentrations compared to typical domestic sewage for most of the quality parameters.

The impact of hydraulic retention time on the performance of two configurations of anaerobic pond for municipal sewage treatment

The study demonstrates the potential of APs to be operated at shorter HRTs in psychrophilic conditions, presenting an opportunity for use as pre-treatments (in place of septic tanks) and primary treatment for full wastewater flows.

Analysis and hydraulic improvement of a maturation pond using Computational Fluid Dynamics

Especially in small communities, little attention is paid to the hydraulic characteristics of wastewater treatment systems. Motivated by this problem, and using the ANSYS fluid dynamics software, the

Nitrogen dynamic in vitro using sludge of a sewage stabilization pond from Patagonia (Argentina)

The first measurements of nitrate-reducing rate (NRR) at lab-scale are reported, using the flow-through reactor technique with sludge of a sewage stabilization pond system located in Patagonia (Argentina), where an unusually high activity of NR was registered.



Dispersion studies in anaerobic ponds: implications for design and operation

It would seem that desludging of the anaerobic pond has a higher impact on the effluent quality compared with improvements to the inlets and outlets, and the removal efficiency of suspended and soluble organic matter might be improved by enhancing mixing within the pond volume.

Research on Waste Stabilization Ponds in the United Kingdom: Sludge Accumulation in Pilot-scale Primary Facultative Ponds

Three pilot-scale facultative ponds, located at Esholt wastewater treatment works in Bradford, West Yorkshire, UK were operated in parallel for 53 months, each with different BOD loadings and hydraulic retention times, finding evidence of degradation in the sludge from the percentage of volatile solids in the dry solids, but insignificant removal of faecal coliforms.

Wastewater stabilisation ponds: Sludge accumulation, technical and financial study on desludging and sludge disposal case studies in France.

Although desludging is carried out only after several years of operation, its cost must be allowed for in the annual operation and maintenance costs of the process, which can be estimated to be 3 ł/person.

The influence of algal biomass on tracer experiments in maturation ponds

Tracer experiments are of concern to wastewater treatment engineers and researchers because of the importance of determining hydraulic regimes and retention times in wastewater treatment units. In

Application of CFD modelling to study the hydrodynamics of various anaerobic pond configurations.

The two-dimensional depth-integrated model MIKE 21 was used in this study to simulate hydrodynamic and advection-dispersion processes in a full-scale anaerobic pond (AP) located in southwest Colombia and showed that a crosswise inlet-outlet layout, a length-to-breadth ratio of 2:1, plus provision of two cross baffles were the most effective measures to improve overall AP hydrodynamics and dispersion patterns.

A CFD model of a field pond that incorporates the first order decay equation for coliforms is presented, showing how treatment efficiency was improved by reducing the short-circuiting through the pond.

Profiling and modelling of thermal changes in a large waste stabilisation pond.

It was evident that even modest winds partially broke down stratification, leading to poor prediction of the gradient by the CFD model, which did not directly account for the impact of wind shear stress on mixing in the WSP.

Comparison of Computation Fluid Dynamics Simulation against Tracer Data from a Scale Model and Full-Sized Waste Stabilization Pond

The use of computation fluid dynamics (CFD) for waste stabilization pond design is becoming increasingly common but there is a large gap in the literature with regard to validating CFD pond models
