How efficient is my wastewater treatment plant?

AERaudit - Economic efficiency analysis in three steps

As part of AERwater’s holistic approach, AERaudit represents a first step in a process chain to provide digitisation, automation and resource efficiency solutions in the field of wastewater treatment, which are precisely tailored to the individual customer process.

As one of the market leaders in wastewater technology, AERZEN accompanies its customers on their journey towards ‘Water 4.0’ by means of AERwater, a trend-setting process optimisation in water management.AERaudit is an innovative service developed exclusively by AERZEN to improve the energy efficiency of wastewater treatment plants. Municipalities in particular must focus on cost savings because wastewater treatment plants are their largest energy consumers. About 60 to 80 percent of the total energy requirement of a wastewater treatment plant is generated in the area of biological purification, in which the oxygen contained in the air is used to purify the wastewater. Only if it is known at which time which air requirement is needed, a meaningful energy analysis for the energetic optimisation of blower stations can be carried out.

As an analysis specialist, AERZEN is a competent partner for the analysis, as well as the design of suitable machines. In three steps, AERaudit then leads to the most economical and future-oriented plant configuration of the corresponding wastewater treatment plant.

  • On-site measurement: The AERZEN service team creates transparency regarding the key performance indicators for your blower station. A mobile measuring station is used to record your relevant aeration data. Volume flow, system pressure, temperature and power consumption are measured in real time and recorded in the form of load profiles.
  • Analysis: The evaluation of the recorded data is carried out carefully and extensively at AERZEN headquarters, every low and peak load, no matter how small, is evaluated. Based on the results, our experts develop one or more concepts, tailored to your requirements, which are as efficient as possible for you.
  • Report: All data of your blower station are displayed in detail and transparently. Temperatures, load profiles and energy costs are visualised in diagrams and explained in detail. We will also show you your customised Performance³ solution with the ideal machine configuration. In addition, how large the saving potential of energy and CO2 is, and which amortisation periods can be achieved.

AERZEN Technology at the L‘Aquarium in Barcelona

The spectacular Oceanario de L’Aquarium in Barcelona is considered the largest and most species-rich aquarium in Europe. With a diameter of 36 metres and a depth of 5 metres, it holds approximately 4 million litres of water. A few months ago, an AERZEN Delta Blower package was put into operation in the L’Aquarium. A large team of highly qualified professionals and cutting-edge technology enables to guarantee the health and wellbeing of over 11,000 animals at the L’Aquarium.

Around 6 million litres of seawater is needed to fill the 21 aquariums. This water is supplied continuously by means of controlled extraction in wells arranged specifically for this purpose. A sophisticated water purification system enables operation in a semi-closed cycle. Purification and filtration are required for a number of reasons. When leftover food, along with the excrement of each organism (with a high ammonium content), is biologically degraded, secondary chemical compounds form (nitrites and nitrates), which are very harmful to the occupants of the aquarium and must be removed. Final sterilisation of the water is required as a biological prevention measure towards the exterior of L’Aquarium.

The new AERZEN Delta Blower starts up in case of emergency, such as an electrical breakdown, and thus makes sure that the water runs out of filtration, and the fishes are provided with oxygen. The circulation of water is what generates oxygen. In addition, in an emergency, porous, pumice-like stones are put in the water to oxygenate the water. The AERZEN Delta Blower provides absolutely oil-free air according to ISO class. For the Aquarium application, it is a must: If the blower was operated with oil it would be fatal for the fishes.
