Mixing Zone Modeling from Effluent Discharge

Efluentemodelo.jpg

Municipal and industrial water treatment plants as well as desalination plants generate effluents that are disposed to different water bodies. The discharge type can be temporal or permanent and the discharge point location could be located on surface or submarine. The main enviromental concern about the discharge is the behaviour from effluent chemicals/nutrients/bacteria on the water body and the associated dilution process to delimitate a mixing area and evaluate the impact on water quality, aquatic ecosystem and dependent species.

Hatarilabs develop mixing zone modeling from effluent discharge on rivers, lakes and oceans, taking into consideration the most relevant conditions related to water quality and flow.

Baseline

The required baseline for the mixing zone modeling is divided on two main parts:

Water body

  • Bathymetry (precision less than 1m)

  • Water qualiy

  • Flow rate (rivers) or currents (ocean)

Effluent

  • Discharge rate

  • Discharge geometry

  • Water quality

Model

The numerical tool selected for this evaluation is OpenFOAM with its solver for miscible flow: interMixingFoam. This tool can handle single/multiple discharge points on complex geometries.

Consulting

We provide solutions based on data analysis and numerical modeling for different challenges in the management of surface water, groundwater, river / ocean hydraulics and others. Our expertise in the model conceptualization, calibration and simulation is the key for developing the best alternatives for your decision making process.

Hatarilabs is a company dedicated entirely to numerical modeling. We process different sets of observed data, construct the numerical tools and simulate the future requirements to surface / subsurface flow regimes.

SIG

Water cycle, commercial activities, ecosystem interaction and other physical process in our environment are spatially distributed. In order to analyse and evaluate current conditions and future scenarios we need Geographical Information Systems (GIS) to connect your data with its position.

Hatarilabs develop different solutions on based on GIS for environmental studies, land cover evaluation, precision agriculture, resources management, climate change impact and others.

Fluid dynamics

Simulation of dynamic behavior of fluids as water or air is essential for engineering process, environmental assessment or industrial design. Hatarilabs can simulate a variety of compressible and uncompressible fluids under a series of temperature, velocity and pressure conditions.

Fluid dynamics models are versatile for fluid simulation in a variety of temporal and spatial scales. Model parameter can be calibrated on laboratory test and model results are of great resolution.

Hydrology

The water cycle is influenced by climatic factors, rainfall. coverage and geology. If a parameter engineering design, or scenario for water management is required, Gidahatari has the right solution.

Gidahatari has a great ability to analyze the phenomena of the water cycle by mastering various hydrological modeling software. Our assessments are aimed at improving watershed characterization, validation of the models with observed conditions and predictive simulation scenario of water use and climate change and / or coverage.

Hydraulics

Rivers and streams present challenges in civil engineering works and planning of water resources. The hydraulic design should ensure good performance to extreme events and performance of works in the long term.

Gidahatari comprises the main factors that dominate the flow in rivers and dominates the main modeling codes including computational fluid dynamics (CFD). Our assessments determine areas of flooding, erosion banks, sediment transport, calculation of hydraulic structures among others.

Hydrogeology

In many parts of the world groundwater resources are in the public interest due to the increasing demands, wasteful use and pollution. To meet this challenge is to implement a good planning and practices of integrated groundwater management.

Gidahatari evaluates the flow regime and groundwater quality at regional or local level, analyzing different scenarios of demand or impact to groundwater resource. We dominated most softwares for hydrogeological and hydrochemical modeling with extensive experience in projects.
