BIRCOprime® allows both decentralised and semi-centralised rainwater treatment, therefore offering planners and architects great flexibility with regard to connection and drainage variants.
BIRCO will also display the following products at the IFAT 2022 (from left): BIRCOdicht NW 300 with slotted cast grating, BIRCOcanal® NW 420, the BIRCOmax-i® NW 520 with slotted cast grating, BIRCOmassiv NW 220 with cast mesh grating, BIRCOpur® direct NW 300 with cast grating with trapezoidal slots and the BIRCOsir® NW 320 with honeycomb grating.

Effective sedimentation in the drainage channel
BIRCO is celebrating the market launch of its new rainwater treatment system at IFAT in Munich (World's Leading Trade Fair for Water, Sewage, Waste and Raw Materials Management, 30th May to 3rd June). It ensures reliable linear drainage during heavy rainfall and the retention of filterable substances (AFS), heavy metals, microplastics and light liquids - all this close to the surface and easy for operators in terms of handling and maintenance. In this way, BIRCOprime® relieves central sewage systems and thus protects water bodies.
Strong system for first-class sedimentation
The drainage expert based in Baden-Baden, Germany will be focusing on the topics of "rainwater management", "heavy load" and "water conservation" at this year's IFAT, presenting its new BIRCOprime® rainwater treatment system for the first time. "Rainwater treatment can often be ensured without filtration. With BIRCOprime®, we already achieve effective sedimentation in the drainage channel" explains Marian Dürrschnabel, Head of Product Management, Marketing & Application Technology. The company relies on a combination of a large-format, robust heavy-duty channel and a sedimentation system made of durable PE components. The BIRCOmax-i® with a nominal width of 520 mm and an overall height of 1200 mm with ductile iron frame forms the body of the system - a self-supporting channel suitable for Type I installation, which can also be fitted in narrow excavations and requires only minimal foundation as support. The treatment system has a total length of 4500 mm with the sedimentation unit integrated therein. Connection areas of between 2000 and 7000 square metres are possible, depending on the operating mode and the required permeability value or efficiency.
Laboratory-tested system with mechanical functionality
The BIRCOprime® achieves effective sedimentation using physical settling processes: The system consists of seven sedimentation chambers formed by six base weirs and one overflow weir. AFS, tyre wear particles, microplastics, petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAH) and heavy metals (e.g. zinc, copper) are reliably retained in the chambers. Due to the intelligent design, only a minimal remobilisation of pollutants takes place, even during heavy rainfall. Testing of the cleaning performance was based on DIBt (German independent institute) testing principles, and in accordance with DWA-M 153 and DWA-A 102 rainwater treatment guidelines. After the sedimentation process, the treated water can be discharged - depending on the discharge variant - vertically or horizontally into sewers, bodies of water, infiltration, retention or utilisation facilities. A retention device separates light liquids that are hazardous to water.
Decentralised and semi-centralised treatment possible
Rainwater treatment can be both decentralised and semi-centralised, therefore offering planners and architects great flexibility with regard to connection and drainage variants. The rainwater inflow can occur both via the cast slotted grating of the channel body (decentralised) and via an upstream drainage system (semi-centralised) - for example via a conventional drainage channel or a pipe system.
Easy maintenance due to modularity and surface proximity
The rainwater treatment system has a modular design. The first and the last weir are permanently installed, the other weirs can be removed. Due to the proximity to the surface and the system design, simple checks and operator-friendly maintenance are possible at any time. These are to be carried out every 1 - 5 years, depending on the local pollutant loads and the size of the connection area.
Also on display at the BIRCO stand
An exhibit in original dimensions gives IFAT visitors an authentic insight into the functionality of the BIRCOprime®. In addition, the exhibitor will present further exhibits as part of its focus theme, including BIRCOpur® direct NW 300 with cast grating with trapezoidal slots. This is a modular filter system embedded in a channel with the option of direct infiltration. BIRCOdicht NW 300 with slotted cast grating has a continuous PEHD lining and offers protection in all areas where water-polluting substances and aggressive media have to be collected. In the heavy-duty area, BIRCO will be showing its BIRCOmassiv NW 220 with cast grating and the BIRCOsir® NW 320 with honeycomb cast grating, as well as the BIRCOmax-i® NW 520 with cast grating. For municipal planners, the drainage expert presents the BIRCOcanal® NW 420, a supply channel that can withstand heavy loads and is designed for the safe installation of pipes and cables. With a view to the growth market of "electromobility", this is particularly suitable for supplying charging stations.
