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.

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



Dear clients and followers, we are happy to share with you the great news that has come on the OPEN DAY of the R+ D + i Manure Ecomine project in Spain.

Our company participates under the Seventh Framework Programme (7th FP) of the European community in the Manure Ecomine project in a partnership with several European universities among which there are several Spanish ones, such as the University of Santiago de Compostela (USC) and the University of Girona (UdG) and private companies, with the clear focus to enhancing cattle manure and produce “green” fertilizers with high added value.

Please find attached project link where you can get more information:


We invite you to the open day that will take place close to Vic (Barcelona) on May 20th, where we will make a presentation of the project and we will guided groups to visit the pilot plant.

Admission is free, but we ask for on-line registration at the following link:


The project sponsor European Commission and the European food industry are very aware of the results obtained in the pilot plant by Ahidra. Again Ahidra is leader in the application of new technologies and chemical engineering processes with the aim of improving existing processes to achieve a more sustainable planet, we strive for the common good.


Ahidra, Water and Energy debuts at the fair SMAGUA 2016:
