The monoblock units of the BIOTAL-MCW type are designed for deep treatment of domestic wastewater with a volume ranging from 2 to 12 m3 per day. They feature a special reactor made of polypropylene, which is located in a round reinforced concrete well. One of the key features of these units is the ability to pump excess sludge into a separate well, where it undergoes stabilization and compression. This enables effective wastewater treatment and optimal sludge management, ensuring the efficient operation of the treatment system.
