AWALIFT with 2nd separation stage - the spike rake

Due to the now very different composition of wastewater, it can happen in individual cases that pump blockages impair the operational safety of wastewater lifting units, due to a high fi brous solids content. In order to continue to ensure reliable solids separation, a second separation stage - the spiked screen - has been developed to prevent these fi brous solids (especially wet wipes) from reaching the pump. Spiked screens can be easily retrofi tted to sewage lifting units with integrated return fl ap. For wastewater lifting stations without return fl aps, there is the option of mounting the spiked screen in a separate housing (cassette or fl ange) between the pumps and the tank.
