Post-treatment units ATF and ATFUV for wastewater treatment plants

Post-treatment units ATF and ATFUV for wastewater treatment plants

The ATF 6 – ATF 20 post-treatment units use biological (biological filtration) and physical (filtration, sedimentation) processes for the tertiary treatment of secondary treated wastewater from small WWTPs. ATF aftertreatment units mechanically and biologically remove undissolved substances and organic pollution from wastewater to a guaranteed level.
ATF post-treatment units have been tested, as well as our domestic wastewater treatment plants, in Aachen, Germany at the PIA testing institute. They meet the European standard EN 12566-7.
Use and description of ATF aftertreatment units
Post-treatment units for tertiary post-treatment of the ATF 6 - ATF 20 type are used when there are increased requirements for the quality of wastewater discharged into surface and underground waters, for example in protected water management areas, or in the case of reuse of treated wastewater. They are installed behind biological wastewater treatment plants of the type AT 6 plus - AT 20 plus or AT 6 plus P - AT 20 plus P.
Cleaned wastewater can be discharged into surface or underground waters, or recycle it by using it for watering lawns and ornamental greenery, or use it for technical purposes.
ATF aftertreatment units can also be equipped with a UV module for wastewater disinfection. The UV disinfection module for domestic wastewater treatment plants was tested in a long-term test at PIA Aachen and demonstrated a very high disinfection efficiency.

All ATF and ATFUV aftertreatment units include control with remote controll in the form of GSM.

Simple installation of the ATF post-treatment unit for domestic wastewater treatment plants
The ATF post-treatment unit is installed in the trench on a 15 cm thick reinforced concrete base plate so that the top edge of the tank protrudes approx. 5 cm above the ground. Detailed installation instructions are provided in the operating procedure, which is attached to the handover documentation. Aquatec VFL's technical team can take care of the installation.
