Leading paper manufacturer PAPELERA NACIONAL S.A. profits from green energy
10-04-2019 -- Global paper manufacturer and distributor PAPELERA NACIONAL S.A. (PANASA) is enhancing its sustainability with a new Global Water & Energy (GWE) wastewater treatment plant in Guayaquil, Ecuador.
The GWE anaerobic plant will convert organic contamination present in the wastewater to up to 4,200 Nm3 of biogas, which when utilized as a fuel, is an equivalent of 2,818 kg fuel oil per day.
PANASA has been producing Kraft paper since 1968. Throughout the years the company has increased its production, installed new equipment and optimized fiber control and preparation processes. Fifty years later, it can produce 18 times more paper, with annual production volumes exceeding 180,000 metric tonnes.
By choosing GWE’s solution, PANASA has the opportunity to tackle two of the most significant problems faced by the pulp and paper industry – efficient wastewater treatment and fossil fuel dependency.
Turning the problem into profit
The organic contamination present in the PANASA’s wastewater stream will be converted to biogas by GWE’s ANUBIX™ – T Expanded Granular Sludge Bed (EGSB).
ANUBIX™ – T anaerobic reactors are designed with a focus on minimal maintenance and operational requirements. Their tower-like design also saves a significant amount of space compared with other wastewater treatment plant designs.
The high efficiency of the wastewater treatment system helps to reduce the environmental footprint of forward-thinking companies like PANASA.
The savings produced by replacing fossil fuels will ultimately cover the entire cost of the wastewater treatment plant and then go on producing profit for the client.
GWE’s ANUBIX™ – T, including auxiliary equipment and tanks, was chosen after a thorough supplier selection process. GWE’s new waste-to-energy technologies incorporated into PANASA’s existing aerobic wastewater treatment facilities as a turnkey project.
Selection of the ANUBIX™ – T turnkey solution is a testament to the engineering ingenuity of the system, and the hard work of the entire GWE team in making sure all of PANASA’s needs were met.
ANUBIX™ – T ultra-high loading rate anaerobic reactor
The ANUBIX™ – T can be used for the anaerobic treatment of wastewater streams in a broad range of applications, including:
- Soft drinks,
- Paper mills,
- Starch production, and many others.
ANUBIX™ - T is an ultra-high loading-rate system utilizing expanded granular sludge bed technology. It is suitable for high-strength wastewaters with organic content up to 15,000 mg/l. It is capable of handling very high loading rates of up to 25 kg COD/m³/d, depending on the type of wastewater.
During the project design phase, additional provisions can be implemented for pre-settling of solids, heating, cooling, CO2 degasification, and inline neutralization, to customize the installation to suit your unique requirements.
