Ahidra-Colsen Technologies, in collaboration with its partner Adeagua, will attend FIGAN 2021 by presenting the new AMFER® technology for the treatment of digestate or raw slurry.

With this technology, the circular economy is promoted in livestock production and in biogas plants, so that the environmental impact and the carbon footprint are reduced, recovering nutrients according to EU directives and reducing waste management costs.

We will gladly assist you at our stand 21-22 (Pavilion 6) between September 21 and 24 at Feria Zaragoza (Aragon, Spain).



Ahidra Colsen Technologies is getting ready for the handover of the Waste Water Treatment Plant for Tirme’s Parc de Tecnologies Ambientals in Marratxí (Mallorca).
The WWTP is capable of treating 360m3/day of digestate liquid fraction and leachate consisting in an N-DN biologic with an MBR configuration and a tertiary treatment with affine filters.

The UF membrane incorporation makes it possible to have a compact system compared to traditional biologic procedures, being able to obtain a permeate exempt of suspended matter, having a certain disinfecting capacity due to the holding of microorganisms, and moreover improving the contact time of the substrate with the biology and the capacity of hydrolysis.

The tertiary treatment is able to reduce the refractory COD that the biologic can not eliminate in order to comply with the restrictive discharging parameters.



Ahidra Colsen Technologies hands over the finished water treatment plant project built for SPF DIANA -Symrise AG group- in the municipality of Cervera in the province of Lleida.

The plant provides a DAF primary treatment followed by a multistage N-DN with MBR secondary system and it is able to low the high charges of phosphorus and nitrogen from the income to achieve the demanding discharge parameters of:

pH 7,0 a 8,0 upH
Total Suspended Solids <50,0 ppm
CODTotal < 180,0 ppm
Nitrogen (NTK) <15,0 ppm
Total Phosphorus <15,0 ppm
BOD5 <90,0 ppm
Nitrates <10 ppm
FOG  < 20,0 ppm
Toxicity <10 equitox/m3



Ahidra starts the construction of the manure treatment plant for the Serentill group and keeps consolidating as the leader of the sector in the biological manure treatment in the Iberian peninsula.

The plant for the farming group will be located in Soses (Lleida region) and the aim of the project is to treat 170m3/day of pig manure with an SBR process of nitrification-denitrification (N-DN) that should assimilate high nitrogen concentrations within a compact installation.  The main advantages that stand out in this kind of plants are the high disposal performance superior to the 80% with a reduced treatment cost, the low employee and supervision requirement due to the complete automatisation of the plant by SCADA and that it is a system capable of treating effluents with different concentrations and flows.

According to the guide of technologies for the treatment of livestock manure from the Departament d’Agricultura de la Generalitat de Catalunya:

the SBR is a BAT that admits a minimum yield of 64% nitrogen removal.

After several years of hard work, intense research and development, several pilot plants and the philosophy of the company to always make available to our customers the most innovative technologies to make this world environmentally better, we are proud to announce that THE NEW POUL-AR® TECHNOLOGY IS ALREADY AVAILABLE, for the treatment of poultry generated in chicken and laying hens farms.

The great problem of directly using the poultry in the agriculture, apart from the environmental, is the inefficient ratio of the nutrients Nitrogen, Phosphorus and Potassium (NPK), becoming into a residue of difficult management.
The key to the success of this new technology lies in the energy recover from the poultry, as well as in the maximum recovery of nutrients to produce a mineral organic fertilizer with a balanced and commercial NPK formula.

¡¡¡From now on with POUL-AR®, poultry manure ceases to be a waste or a bad fertilizer for agricultural use directly, to become into a great income, contribute to the circular economy and to significantly reduce the production of greenhouse gases!!!




Commissioned a wastewater treatment plant for a multinational food industry in Girona region.

Ahidra, agua y energía, S.L. has commissioned a wastewater treatment plant for a multinational food industry in Girona region, where a biological aerobic treatment using the ultimate control system developed by Ahidra for Nitrogen removal has been implemented.


IFAT 2016

For a SME like Ahidra, it is a great economic and human effort to be present at the IFAT 2016, but once again Ahidra shows that it is up to the expectations of our customers. We have been novel in the IFAT, but we counted on the factors of illusion, motivation and passion for what we do. We contribute to make this world a better place. With these ingredients, the result could not be other than success. Lots of visitors to our stand very interested in our technologies. The Manure Ecomine Project continues awaking interest, as well as our patent NAS® (Process Anammox). The Ahidra team is highly satisfied with the work done in the IFAT 2016 and with the results obtained, however our innovative DNA has already led us to work on ideas for improvement for the next edition of 2018, where we will be definitely present, showing the best available technologies to look after our planet.


IFAT 2016

Dear customers and partners, following the commercial strategy marked by management and after the great success achieved in SMAGUA 2016, Ahidra gets pretty and travels to Munich. We are pleased to inform you that largely Ahidra will have its own booth exhibitor at the IFAT 2016 (Hall A4, Booth 104). Throughout the week Oscar Benito (MD), Alexis Diez and Daniel Caballero will wait you at the stand with the best available technology to provide real, efficient and effective solutions to your problems. Our goal is to help you achieve a more sustainable planet.

Ahidra whole team is very excited about the IFAT 2016 and our presence there, we are aware that it is the perfect international showcase for Ahidra. IFAT 2016 trade fair is the world’s most important environmental technologies focused on water management, disposal and recycling of waste and sustainable resource management. The right time in the right place with the most efficient technology possible, success is guaranteed.

All are invited to share with us this great illusion. You can request your custom passes in info@ahidra.com
