Rainwater - Electrical Throttle

Biogest - Model Type EGAR - Electrical Flow Regulator for Rainwater Management

The Electrical Flow Regulator Type EGAR is a sophisticated device engineered to manage hydraulic conditions in urban drainage systems, specifically to prevent overloading of sewer systems and wastewater treatment facilities during periods of rain. It operates by adjusting runoff quantities through advanced control mechanisms, ensuring that discharge volumes remain consistent irrespective of stormwater accumulation levels. The system utilizes an electric drive to modulate a slide plate, relying on continuous comparison between actual and set values of water level. The automatic response includes blockage detection, which repositions the slide plate to optimize flow through the system. Additionally, it features preparation for telecontrol and allows for stepless adjustment of discharge quantities. With its vertical Q/H characteristic and compliance with DWA A111/A166, the EGAR is designed for efficient and reliable operation in the congested conditions of rain retention systems.

Biogest - Model Type SDS - MID Flow Control - Sewer System Throttling Device

The MID Flow Control Type SDS is an advanced throttling device engineered for optimal sewer system management, particularly during variable weather conditions. It employs a magnetic-inductive flow meter (MID) to measure discharge in both partially and fully filled pipes, supporting accurate flow control. During dry weather, the system's control slide remains fully open, ensuring unrestricted flow. However, in rainy conditions, once the discharge volume surpasses a set threshold, the electric control drive activates, adjusting the slide plate position to maintain the desired flow rate. This device automatically corrects for blockages by adjusting the slide to eliminate obstruction, ensuring continuous accurate discharge control. The electronic controller consistently aligns the flow with predefined setpoints, efficiently managing flow even in the event of backflow scenarios. This solution is paramount for preventing hydraulic overload in connected wastewater treatment facilities, ensuring stable operations across diverse environmental conditions.

Biogest - Model Type NSA - Emergency Gate Valve for Fire Water Retention

The Emergency Gate Valve Type NSA, designed in accordance with the Water Resources Act, is crucial for facilities such as forwarding agencies, waste disposal companies, and industrial depots that must retain contaminated extinguishing water or water-polluting substances. This system integrates with fire alarm systems to actuate safety slides, preventing contaminants from entering the public sewage system. In case of fire, automatic slide closure ensures containment, whereas manual override with a square key or e-key allows operation during power failures. This system is integral to emergency plans and prevents hazardous substances from reaching natural water systems or municipal treatment facilities, offering an essential layer of protection for environmental safety.
