At Grupo Vento we are committed to environmental sustainability in all our projects

We have extensive experience both in carrying out environmental action projects, as well as in the implementation of technical solutions related to the environment.

Minimization of wastewater discharge, neutralization and scrubbing of gases, stabilization by drying, recovery of industrial solvents … A sustainable solution for every need.

Some of our success stories

Evaporation/cristallization. ZLD (Zero Liquid Discharge)
Evaporator-crystallization system (ZLD, Zero Liquid Discharge)

The evaporator itself is a producer of evaporated water with excellent characteristics to be reused in the process, generating a flow much higher than its consumption needs.

The evaporation / crystallization unit for ZLD (Zero Liquid Discharge) will basically consist of a multiple effect evaporation system with a final crystallization reactor.

This unit allows high degrees of total concentration in the effluent. However, it must be taken into account that the consumption of water in a water evaporation equipment should not represent any problem, since the evaporator itself is a producer of evaporated water with excellent characteristics to be reused in the process.

ZLD Systems are recommended for their energy efficiency and optimization of water resources, constituting a true zero discharge system.

New evaporation technology for the almond industry
Reduce water consumption in your company by 98%. It solves the environmental problems originated by almonds blanching and peeling.

This novel minimization system based on multiple effect vacuum evaporation processes, working under low operating costs, allows to obtain distilled water, meeting extraordinary characteristics to be reused in the process of blanching and peeling the almond itself, constituting a “zero liquid discharge” system.

In this way, it is possible to solve the environmental problems that these almond handling processes entail by reducing water consumption (which is so scarce in recent times in our country).

The technological viability of the project has been endorsed by a prestigious organization such as the CDTI.

Complete process for olive oil vegetation wastewater treatment
Through this process, distilled alcohol, evaporated water and soluble organic matter concentrate are obtained.

New technology that allows solving the environmental problem of companies producing olive by-products.

In collaboration with Coop. Comarcal Valle de Albaida and AINIA, a new technology has been developed that has made it possible to solve the great environmental problem of companies producing olive by-products by applying a global process that provides technical and economic benefits.

Evaporation system for wastewater minimization
Energy efficiency and optimization of water resources: It constitutes a true zero discharge system.

The evaporation unit for minimizing liquid effluents is basically composed of a simple effect evaporation system with external tubular to facilitate the cleaning of the tubes in case of possible fouling.

However, it must be taken into account that water consumption in an evaporation equipment should not represent any problem: the evaporator itself is a producer of evaporated water with excellent characteristics to be reused in the process.

Built according to European standards for machine design. CE marking.

Success stories

Recovery of dirty solvents
The control of the process is carried out by means of PID regulators. ATEX certified.

The equipment is basically made up of two units: a continuous distiller and a condenser for the solvent vapors produced in the first. Once the equipment has been emptied, it can be refilled by closing the discharge valve and starting the distillation cycle again.

VOCs depuration plant with solvent recovery
It combines absorption, distillation and purification processes.

Process specifically designed for the recovery of solvents (VOCs – volatile organic compounds) from waste gases. The main principle is the absorption of solvents, at room temperature, over a small flow of specific absorber liquid, and subsequent distillation of the same. This system allows the recovery and purification of solvents with minimal energy consumption.

Installation example: Installation for VOC purification and solvent recovery for 40,000 Nm3/h for Trelleborg Navex in Cascante, Navarra.

Minimum energy consumption and high solvent recovery. Compliance with the RD 117/2003 emission standard.

Radiant turbine dryer: r.t.d.
Low cost continuous dehydration system

Drying and stabilization of industrial sludge, reduction of the waste discharge volume as well as management costs.

The RTD, radiant turbine drying unit, is developed for the continuous evaporation of materials requiring conditioning, in terms of humidity and biological stabilization.

This system is provided with an electrical and control panel to regulate the speed of the motors, detect and transmit pressure and temperature parameters, both for the steam station and for the product. It also allows modifying the work parameters from an operator terminal.

Designed according to European standards for machine design. CE marking.

Possible applications: Industrial sludge drying; Paprika drying and sterilization; Lime Tartrate Drying; Potassium bitartrate drying; Sodium sulfate drying; Drying of active principles of medicinal plants.

Trommel dryer
Decrease in the volume of discharges. Management costs reduction.

Very good heat exchange performance in short residence time. Drying and stabilization of the product.

We have developed two different types of TROMMEL dryer depending on which is the source of calorific input to the Drying Unit.

DIRECT when it comes from combustion gases from a cogeneration unit or from the combustion chamber of the dryer itself.

INDIRECT when the calorific input comes through steam or superheated water (ASC) where there is no direct contact between the steam and the product to be dried.
