iCBA^®-Aeration System

Settling contaminants such as sand not only impair the cleaning performance of a sewage treatment plant, but also cause serious damage to the equipment. The aeration of the sand trap accelerates and improves the settling behavior of mineral solids and thus prevents operational disruptions.

The robust iCBA^®-Aeration System has been specially developed for harsh operating conditions. The durable stainless steel construction ensures long-term reliable gassing performance.

HYPERCLASSIC^®-Mixer

To discharge wastewater into the public sewer system or an in-house biological treatment plant, the pH value must be within the permissible range of 6.5 to 9. To adjust the pH value, acids or bases are specifically added to achieve neutralization.

The CYBERPITCH^®-Mixer is ideally suited for this purpose. Thanks to its robust design made of high-quality stainless steel and its flow-optimized blade design, it ensures effective and uniform mixing. The construction is specifically designed for turbulent flows, thus efficiently supporting the neutralization of wastewater.

The HYPERCLASSIC^®-Mixer is also used for neutralization and stands out due to its high energy efficiency during tank content mixing. It is the preferred choice when effective neutralization and economical use of energy are both required.

HYPERCLASSIC^®-Mixer

In addition to adjusting an optimal pH value, the selection of a suitable mixer is essential for a successful precipitation reaction. For destabilizing the colloidal state, high energy input and extended contact time between the precipitant and the colloid are required to form microflocs.

The CYBERPITCH^®-Mixer combines these aspects through its flow-optimized mixing blade and high-speed design.

The GRF-Mixer also unites these aspects with its proven blade shape and application.
In cases where a less energy-intensive mixing design is required, the HYPERCLASSIC^®-Mixer is an excellent choice.

HYPERCLASSIC^®-Flocculator

The success of macrofloc formation relies on gentle mixing that simultaneously ensures complete recirculation of the entire tank content and the flocculation aids within the retention time.

The HYPERCLASSIC^®-Flocculator, with its hyperboloid-shaped mixing body and low rotational speeds, minimizes shear forces while ensuring complete tank mixing. This promotes frequent particle interactions, enabling maximum floc growth.

HYPERCLASSIC^®-Mixer

The use of powdered activated carbon (PAC) for the treatment of the waste water eliminates a wide range of different organic carbons (DOC) and trace substances, thereby significantly improving the waste water quality.

A high local energy input is required for quickly mixing the PAC into the waste water flow – the CYBERPITCH^®-Mixer is suitable for this.

The HYPERCLASSIC^®-Mixer is used during the reaction time in the adsorption stage. The low speeds, large mixer diameters and installation of the mixer body close to the ground ensure complete, low-shear mixing.

HYPERCLASSIC^®-Mixing and Aeration System

In stripping, substances are transferred from a liquid phase to the gas phase through desorption, applying Henry’s law. In this process, the liquid is brought into contact with a gas—typically air—using the countercurrent principle. In wastewater treatment, this method enables the removal of substances such as ammonia, hydrogen sulfide, mercaptans, phenols, organic halogen compounds, and hydrocarbons.

The iCBA^®-Aeration System is particularly well-suited for introducing large volumes of gas. If solids also need to be kept in suspension, the HYPERCLASSIC^®-Mixing and Aeration System provides an almost ideal solution, as it combines effective mixing and aeration.

HYPERCLASSIC^®-Mixing and Aeration System

In mixing and equalization basins, wastewater from various areas is collected and homogenized. This effectively prevents peak loads on the biological part of the treatment plant. In some cases, a mixing and equalization basin even serves as the sole treatment stage for wastewater directly on the company premises. Here, the wastewater is collected during the day and discharged into the municipal wastewater treatment plant at night when its load is at its lowest.

For this application, the HYPERCLASSIC^®-Mixer is particularly suitable due to its high circulation capacity.

In some cases, mixing and equalization basins are aerated to prevent anaerobic conditions and enable the degradation of pollutants in advance. For these requirements, the HYPERCLASSIC^®-Mixing and Aeration System offers an optimal solution, as it ensures both effective aeration and reliable mixing.

HYPERCLASSIC^®-Mixer

Anaerobic processes play an important role in many industrial and municipal wastewater treatment plants. In the process, organic compounds are fermented in the absence of oxygen and, via intermediate stages, methane, among other things, is produced as the end product.

If mechanical mixing is required for these processes, the HYPERCLASSIC^®-Mixer represents an optimal solution. The agitator body is installed close to the ground and generates a strong radial bottom flow. In addition, thanks to its high pumping capacity, it ensures that the entire contents of the tank are thoroughly mixed and thus that the entire reactor is used efficiently.

Numerical flow simulation (CFD) is an important and reliable tool for checking the interaction of the building geometry (inlet and outlet situations, baffle plates, overflows, etc.) with the existing or planned installations. This allows the efficiency of the entire system to be evaluated under different load conditions. Possible weaknesses in the design, such as additional turbulence, which can generate an unplanned oxygen input, can be identified and optimized in good time.

HYPERCLASSIC^®-Mixing and Aeration System

In a selector, conditions are optimized to promote the growth of desired microorganisms over undesired ones. The selector is placed upstream of the biological treatment stage, where the return sludge is intensively mixed with fresh wastewater. A selector can be operated either aerated or non-aerated, with intensive mixing required in both cases.

For this reason, HYPERCLASSIC^®-Mixers are particularly suitable for non-aerated selectors, while HYPERCLASSIC^®-Mixing and Aeration Systems are ideal for aerated selectors.

HYPERCLASSIC^®-Mixer

In biological phosphorus elimination, the phosphate storage of the cells is prepared under anaerobic conditions and the supply of organic substrate. Thorough mixing of the activated and return sludge with the inflow volume flow is essential for this.

The HYPERCLASSIC^®-Mixer, which generates a bottom flow directed radially outwards, is suitable for this. Activated sludge is transported upwards along the tank wall. At the water surface, the speed has reduced to such an extent that no oxygen is introduced. The phosphate content can be efficiently reduced through the even distribution of the activated sludge flakes in the wastewater.

HYPERCLASSIC^®-Mixer

In denitrification it is crucial that the activated sludge is homogenized with the recirculation and feed stream. Oxygen entry at the water surface must be effectively avoided.

The HYPERCLASSIC^®-Mixer was specially developed for this. It generates both a high pump volume flow and a strong, radially outward bottom flow. Activated sludge is transported upwards along the tank wall. At the water surface, the speed has reduced to such an extent that no oxygen can be introduced.

HYPERCLASSIC^®-Mixer

The ammonium in the wastewater is oxidized to nitrate by bacteria using dissolved oxygen. This requires an energy-efficient ventilation system.

The modular E-FLEX^®-Aeration System has a flat design close to the ground. An oscillating movement of the EPDM membranes results in a high bubble separation frequency and thus creates very small bubble sizes with a long residence time. For installation and maintenance work in filled tanks, the E-FLEX^®-Aeration System can also be supplied as a liftable solution.

The iDISC^®-Aeration System is predestined for this. It is a highly efficient, fine-bubble membrane aeration system that is suitable for a wide variety of pool geometries due to its modular design.

The E-FLEX^®– and the iDISC^®-Aeration System can be combined with the HYPERCLASSIC^®-Mixer and is suitable for intermittent processes..

The TEX-FLEX^®-Aeration System with its robust stainless steel construction and textile membrane is the right choice for aggressive media.

The HYPERCLASSIC^®-Mixing and Aeration System offers real advantages, especially for industrial use. The purely mechanical ventilation system reliably ensures an efficient supply of oxygen with a constantly low pressure drop. In stirring mode, it ensures optimal mixing of the tank contents.
