RoClean Grande — SBR biological wastewater treatment plant from 75 to 300 PE.
For apartment complexes, hotels and large developments. From 75 to 300 PE.
The RoClean Grande is a biological wastewater treatment plant with SBR (Sequencing Batch Reactor) technology, built into a single-piece, weld-free RoTerra HDPE tank. Factory pre-assembled, with control panel, compressor and sampling basket included. Available from 75 to 300 PE — for apartment complexes, hotels, schools, light industry and large residential developments. CE certified. Silent and odour-free.
Why the RoClean Grande?
For larger projects with no connection to the public sewer network, the RoClean Grande is the most reliable industrial solution in the RoClean range. The system has no moving mechanical parts inside the tank — all the SBR technology runs on air-lift pumps, ensuring low maintenance and a long service life even in heavy-duty installations.
The RoTerra HDPE tank is rotationally moulded as a single piece, with reinforced wall thickness and ribbing for deep installation. It withstands soil pressure and groundwater. Plug-and-play installation — just connect the pipework and the electrical cable to the external control panel.
