ASA-Weirs serve primarily as cascade dams, flushing weirs and relief weirs. They activate reservoir volumes, generate hydropeaking and make a variable overflow edge to separating structures and relief dams. Technically, the ASA-Weirs are XXL hydraulically-driven, pressure- sealed sliders, manufactured with the highest level of precision.

The state-of-the-art standard-solution for keeping floating materials as a follow-on solution to the fixed baffle, ideal for an upgrade. The baffle is used for holding floating materials at discharge equipment and thus ensures that the discharge of paper, hygiene articles, waste and other floating materials is reduced and prevented as much as possible. Floating baffles offer the advantage that they continuously adapt to the water level and thus to the retention effect.

The solution for storage sewers without installations in the flow cross-section. The AWS flush sluice is a cleaning system for sewage storage spaces and canals of any cross-section sizes. Deposits are dissolved and transported by flushing waves.

The most operationally cost-effective and most commonly installed solution for cleaning reservoirs. The AWS-Flush Bucket which is installed outside of the medium (storm water, drainage water etc.), removes deposits without external energy and extremely effectively due to a strong flushing wave. The shape of the AWS-tipping bucket constructed on the basis of FEM-models is characterized by an optimal torque curve and material usage rate with a low net weight and is the most modern construction on the market.

Segmental weirs are used anywhere where more precise regulation of the water volume is required at high water pressures. Due to the stress capacity principle, they can be operated with low torque and thus lower drive power. To be more economically, the frame-bar construction of the segmental weirs are fitted with a projecting baffle plate, with this they can be used for samller dam structures and drainage volumes.

AWS pico stream jets are small, fixed or pivoting ventilators and flow generators with 2 - 8 kW of power. They are used for ventilating drainage and process water and for disposing deposits in smaller structures, flushing or pump sumps. The AWS stream jet‘s little brother has overall DATA EFFICIENCY with HydroMatic-IntelliGrid, TeleMatic, smartSCADA and smartKANiO. Now, small storage spaces can also be effectively cleaned using this method, which has been tried and tested thousands of times.

Airlift is a solution for mixture and circulating wastewater with coarse-bubble aeration. In this case, pipelines with special bores are linearly mounted on the pool wall above the tank bottom. The air is driven with determined pressure and the resulting bubbles circulate the wastewater in the pool. Since they are coarse bubbles that rise quickly to the surface and then strip, a solution of the oxygen in the wastewater is avoided. The intelligent automation solution TeleMatic controls the valves of the air lines. When using the airlift in denitrification tanks, oxygen measurements are installed and included in the automation solution. These measurements provide the certainty that in the circulation process, no oxygen goes into solution and is consumed by the bacteria.

The most economic drainage regulation, electronically adjustable – ideal for the exchange of mechanical throttle devices. The HydroMat-E drainage controllers are electrically driven, level-controlled flow volume or water level regulators. The respectively intended control tasks can be parameterised in a user-friendly way using the corresponding HydroMatics system software from the TeleMatic family.

The „System Hydro-Klar“ clean water discharge equipment can be implemented in a variety of ways in both water supply systems and in waste water treatment plants. In SBR water treatment plants, they are used for the water level-based clean water separation during the SBR process. The automatic and optionally opacity measurement-regulated system conducts the clean water to the receiving water in a process-controlled manner (according to time and volume). By selecting the maximum extraction quantity, the reserves for the flushing process can be significantly increased. Using the supplied HydroMatic control, the regulation of the outflow quantity is based on the current water level.
