W&E TECHNOLOGIES

w&e technologies

Aqualogy Water & Energy Technologies is a multidisciplinary department consisting of more than 250 professionals, with references in over 15 countries around the world. Its activity is focussed on the design and development of projects and the implementation of advanced solutions for the optimisation of complete water cycle processes. Its main lines of action are:

  • Wastewater treatment (urban and industrial)
  • Sludge and biomass
  • Distribution and drainage networks
  • Basin management
  • Hydrogeology
  • Energy
  • Control and automation system

Aqualogy W&E Technologies offers a global service that covers everything from the study and design of the solution to its implementation, commissioning and maintenance. Its portfolio consists of over 80 services and solutions that adapt to the customer’s needs in both the urban and industrial field, and always with innovation as our benchmark.

Of particular note are patented technologies such as electrochemistry for water treatment, low-temperature sludge drying and cleaning and maintenance of CO2 wells, as well as sophisticated decision support systems for asset management or optimised, real-time management of drinking water supply networks. Projects related to energy efficiency are also a benchmark, as they propose solutions that not only permit precise monitoring of energy costs, but also savings in consumption and controlled demand. And all this without forgetting the more traditional engineering projects, such as master plans or the design of water infrastructures, where a wide variety of references are a guarantee of our work.

Aqualogy W&E Technologies offers a global, professional and technologically innovative service.

SLUDGE AND BIOMASS: Continuous thermal sludge hydrolysis (Aqualysis)

One of the current challenges in wastewater treatment is to increase sustainability through energy self-sufficiency: having a treatment plant that is capable of producing, on site, all the energy necessary for its operation.

Aqualysis continuous thermal hydrolysis technology generates more energy because it produces more methane in the anaerobic digestion process. It also generates less end waste, thanks to better degradation in the anaerobic digestion and dewatering phase. Aqualysis is notable for its fully continuous operation, the direct heat transfers and the exclusively designed flash system, for greater compactness and efficiency. A higher degree of reliability is also achieved, as bigger loads can be digested, freeing space in the digester and accelerating the process. It is a firm commitment to zero waste.

SLUDGE AND BIOMASS: Drying of sludge and biomass

Aqualogy develops high-quality technological drying solutions, combined with energy-efficient measures and respect for the environment, thanks to in-house technology based on the application of solutions for the use of residual energy and heat pumps.

Its low-temperature dryer reduces the volume of sludge, both industrial and urban, from wastewater treatment plants and various industrial processes, as well as various types of biomass, facilitating the use of various types of residual energy. The end product can be used for agricultural purposes or as an alternative fuel.

ENERGY EFFICIENCY: RENEWABLE ENERGIES

Aqualogy has the capacity to carry out detailed analyses and studies of sites, draft and execute projects and operate and maintain facilities in the field of renewable energies. This solution includes photovoltaic solar energy, mini-hydraulic and pico-turbine projects by means of apt systems®, developed by Aqualogy.

HYDROGEOLOGY: GROUNDWATER CATCHMENT MANAGEMENT

Monitoring variables and obtaining characteristic and efficiency ratios for wells (taking into account the aquifer, hydraulic performance of the drilling and electromechanical performance of the propulsion equipment) permit the optimisation of water extraction costs and improved guarantees of supply.

Drilling audits are a means of establishing the condition and efficiency of each of the catchment elements and options for improvement by adjusting the flow, development/descaling of the well and/or modifying propulsion equipment and facilities. AQUA GARD™ is a system preventing efficiency and quality loss, which uses liquid CO2 and does not require the electric pump to be uninstalled.

HYDROGEOLOGY: Hydrogeological consultancy

Hydrogeological studies are the tool that enables groundwater resources to be characterised and quantified. Techniques applied include hydrogeological cartography, geophysics, hydrogeochemistry, drill diagraphy, control network monitoring, demand assessment and flow and pollutant transport modelling.

Their results are directly applicable to defining borehole and beach well sites, assessing renewable resources and reserves, decontaminating groundwater, carrying out artificial recharge and the drainage of excavations and mines, among others.

HYDROGEOLOGY: DRILLING, REHABILITATION AND EQUIPPING OF WELLS

Aqualogy undertakes the complete works for wells and boreholes for water catchment. The drilling is carried out using the most appropriate system for each type of rock, diameter and depth of the works.

Developments, cleaning and pumping gauging/tests are also performed using high-power equipment, and the pumping equipment, power supply and surface civil engineering work are designed, supplied and installed. The Aqua Freed® system is used for the development and descaling of wells using liquid CO2, which is appropriate for drinking water facilities, is environmentally compatible (no acid water generated) and has a greater radius of action than conventional systems.

URBAN WATER AND DISTRIBUTION NETWORKS: CARTOGRAPHY AND PLANNING

Planning studies and operation diagnoses of drinking water networks. Raising and modelling of supply networks. Stock-taking of assets and hydraulic infrastructure and their implementation in GIS.

The Water Master Plan is a consulting service that facilitates:

• Acquiring thorough, accurate knowledge of the water distribution network.

• Conducting a diagnosis of current and future operations.

• Performing a comprehensive service diagnosis (including hydraulic operation, water quality, resource availability, physical condition of facilities and networks, and so forth).

• Optimising actions to be carried out on the network to guarantee their correct operation, based on a comprehensive diagnosis.

• Establishing the principles for improving network efficiency.

 

BASIN MANAGEMENT: WATER PLANNING

The purpose of water planning is to plan all the actions required to guarantee that the entire demand for water is met and ensure the good condition and protection of bodies of water, thereby guaranteeing balanced and harmonious regional development. These solutions include drawing up hydrological plans for basins, demand studies, water resource studies, planning of surface water bodies, water resource inventories and alternative water resource use plans.

URBAN WATER AND DISTRIBUTION NETWORKS: NETWORK MANAGEMENT (NRW)

Studies and projects aimed at improving performance of drinking water networks through adaptation of optimum network pressures and sectorisation design to improve leak detection and permit the control of minimum night-time flows. The purpose of these projects is to reduce non-revenue water (NRW) and thus improve the drinking water distribution service and optimise investment to improve the economic performance.

URBAN WATER AND DISTRIBUTION NETWORKS: ASSET MANAGEMENT

Consultancy and engineering work for the management, maintenance and updating of information on water infrastructures. It permits the assessment and diagnosis of the state of drinking water supply networks. Management systems for decision making on network renewal and rehabilitation, thus enabling prioritisation of network renewal requirements, including investment cost analysis and subsequent optimisation.
