Tips for planning your very first water treatment plant

The treatment of wastewater inside the aeration unit is not only the most important stage in current wastewater treatment procedures, but it’s also the most energy-intensive. If you are an operator of Plantas piloto de tratamiento de agua and want to improve the energy balance of the water treatment plant, increasing the aeration in the aeration tanks provides you with a significant amount of operational margin.

The correct dimensioning of aerators, the selection of the best technologies, and the logical data-guided management of the operation inside the aeration tank are, therefore, the focal points of plant design. Furthermore, energy consumption and emissions may be considerably reduced by including integrated provisions into new project planning and renovation.

Factors Contributing to Efficient Wastewater Treatment

For the comprehensive job of wastewater treatment to be effective, all-important goal aspects must be adequately considered:

  • Cleaning performance
  • Operational stability
  • Costs

Cleaning performance is the most important metric for measuring the effectiveness of wastewater treatment in a wastewater treatment plant. After all, it’s important to adhere to applicable regulatory limitations, which, based on the usage of the treated wastewater, might even surpass the German Wastewater Ordinance’s minimal standards.

The plant’s sustainability should be evaluated in the same light. Even when under shock loads, a wastewater treatment facility must maintain the required performance statistics. However, technology that has outlived its useful life, as well as operational modes with significant material wear, might endanger this.

In the day-to-day functioning of such a wastewater treatment plant, energy prices are practically the only cost component that can be considerably changed. Other expenditures, like operating personnel and maintenance, must be considered fixed to the greatest extent feasible. When constructing a new facility, critical decisions regarding future energy consumption are taken in the early stages.

With over 10,000 community wastewater treatment plants across the country, new development is an exception. As a result, changing plant components is considerably more common. In reality, however, this is typically only done when it is essential to replace failing technology; in very few situations, this is done “simply” to optimize cost structures.

The design of Plantas piloto de tratamiento de agua layout, as well as the selection of operating parameters, has an influence on other significant aspects like the nature & amount of wastewater sludge, as well as the possibility of nutrient recovery.

Wastewater Treatment: Energetic Aspects

Piloto de tratamiento de agua plants consume about 20% of energy consumed by municipal facilities. This demonstrates the positive influence that energy savings may have on a municipality’s finances. However, the concept that treatment of wastewater is energy-intensive & hence provides a significant savings opportunity also applies to commercial operations.

There is also an ecological perspective, in contrast to the financial one: According to research performed by Federal Environment Agency, operators may save an average of 31% without spending on new machinery, reducing emissions of almost 900,010 tonnes of CO2 each year.

The oxygenation of wastewater inside the aeration tank, in which the biological treatment is performed, accounts for approximately 50% of the energy consumed by a wastewater treatment facility. Furthermore, plants that treat wastewater sludge contain agitators that are continually operating.

Furthermore, wastewater treatment plants do not simply use energy; in many situations, they generate it as well. The wastewater treatment facilities of size classes 5 and 6, which serve the bulk of the inhabitants (PE) in Germany, inject wastewater sediment into digestion towers.

Aeration is just a focal point for plant construction

The aeration of an active aeration tank necessary for biological treatment contributes to around 50% of total energy consumption in big wastewater treatment facilities, & the proportion is considerably greater in smaller plants. Efforts to minimize operating expenses should so begin here.

Expert modification of such system configuration to particular requirements of the wastewater processing plant, whether fresh planning or renewal investment, can produce considerable benefits. Blower technology, the size & number of separate blowers & intelligent management of them all provide significant design flexibility. For decades, Keiken Engineering has worked closely alongside operators of Plantas piloto de tratamiento de agua, including client needs in the construction of products & solutions.

Keiken Engineering offers highly advanced blower technology in the context of the Performance3 concept, as well as the accompanying control software & knowledge for coordinating the entire system to assist clients with the entire optimization of their aeration. Keiken Engineering assists customers beginning with the planning phase & works with them just to complete the necessary draft. Expertise from a wide variety of projects, as well as particularly created planning aids, helps in the discovery of a quick, sensible, & future-proof solution.

In-plant construction, flexibility is in demand

The energetic optimization of aeration allows for significant reductions in energy expenditures & emissions at Plantas piloto de tratamiento de agua. In practice, implementation is frequently challenging, particularly in municipal organizations. Although investments with blower technology soon pay for themselves because of the significant efficiency benefits, obtaining the funding is a barrier to adoption.


The maintenance & operation of wastewater treatment plants is a complicated process that is required for the proper wastewater treatment before it is released into the environment. Industrial wastewater is indeed a byproduct of industrial activities & is distinct from household wastewater sources. Many requirements should be fulfilled to properly operate a Plantas Piloto de tratamiento de agua in compliance with regulations.
