Environmental Consulting

Disponemos de software de Cálculo y Predicción de Emisiones y Calidad del Aire (CALPUFF) acoplado con un procesador de datos meteorológicos (CALMET), que procesa datos topográficos (elevaciones) y de usos del suelo para procesar la información meteorológica de la zona de estudio y generar los campos de viento y temperatura en una malla tridimensional, además de otros parámetros relacionados con la dispersión que incorpora diferentes métodos de cálculo. CALMET-CALPUFF es un modelo aprobado por la Agencia de Protección del Medio Ambiente de los EEUU (US EPA).

• Assessment of air quality in a pre-operational situation, previously to the implantation of an activity in an area.
• Assessment of the emissions and air quality during the performance of an installation.
• Identification of emission sources, potential problems and planning of corrective emissions.
• Delimitation of sensitive areas and polluted areas in land planning.
• Proposal and previous analysis of corrective measures.
• Preparing inventories of emissions.
• Drawing action plans.

We use the software Calculation and Prediction of Environmental Noise (Predictor Standard TYPE 7810G), which includes different calculation methods that comply with the environmental noise regulations (RD 1315/2005, RD 1367/2007).

• Assessment of environmental noise in a pre-operational situation, previously to the implantation of an activity in an area.
• Assessment of the environmental noise during the performance of an installation: positioning of emission sources, drawing of isophonic line maps.
• Identification of noise sources, potential problems and planning of corrective emissions.
• Delimitation of acoustic areas in land planning.
• Drawing strategic noise maps for those towns/villages within the scope of application of the RD 1513/2005.
• Proposal and previous analysis of corrective measures.

For the modelling of the pollution of soil/groundwater and risk analysis we use specific software, called RBCA TOOL KIT for Chemical Releases, version 2.6 e) 2009 (Groundwater Services Inc.).It is based on the RCBA methodological guide by standard E 2081 – 00 “Standard Guide for Risk-based Corrective Action” (April 10^th, 2000), published in November 2000 and originally published as PS 104-98.

For other objectives, the underground flow modelMODFLOW (McDonald y Harbaugh, 1988[1]; McDonald et al., 1991) has been used. This model solves the underground flow equation in partial derivatives by means of finite differences in a three-dimensional porous medium. It is more complex to use than RBCA and needs a greater knowledge about the medium.

• Identification of potential sources of pollution.
• Identification of migration routes.
• Analysis of possible transport routes.
• Delimitation of the magnitude of pollution events.
• Help in decision making and action plans.
• Help in decision making about the management of water resources.

EDAR Optimiza is an innovative energy efficiency tool developed by the innovation area of the Department of Environmental Control of ENVIRA Ingenieros Asesores.

The serviceEDARO ptimiza includes:

• Identification of the points in a water treatment plant (WTP) where it is possible to implement energy saving measures, maintaining or even improving the quality of the water treated.
• Jointed modellization of the energy behaviour and the performance of the treatment process. It is the only tool to do so in the field of WTP’s energy efficiency.
• It improvesenergy saving and the performance in the biological process.

The tool EDAR Optimiza offers different levels of service:

• Preliminary analysis: this service includes a salesand technical visit to do checks and tests, together with a technical-economic assessment of possible improvements for the plant.
• Implementation of EDAR Optimiza: it includes field work (collection of experimental data), modellization of EDAR Optimiza, final proposal for improvements together with all the proposals for optimization and quantification of the saving that would be achieved.
