Comparison of AT – AT PLUS – AT MBBR. Aquatec WWTP technologies.

• Standard model of wastewater treatment plant with VFL technology.
• The WWTP can be equipped with the AQC Basic or AQC Basic GSM control unit.
• AT wastewater treatment plant includes a manual air distributor.
• AT wastewater treatment plants meet: Category I. and Category II. according to the Regulation of the Government of the Slovak Republic No. 359/2022 Coll. for discharge into surface and groundwater for source sizes up to 50 EO.

• Automated model of wastewater treatment plant with VFL technology
• The wastewater treatment plant is equipped with the AQC Plus GSM control unit.
• The air in the AT Plus wastewater treatment plant is distributed automatically using an electromagnetic valve, which operates based on software designed by Aquatec VFL. The wastewater treatment plant does not contain any mechanical valves.
• The AT Plus WWTP can be equipped with probes for sensing the wastewater flow rate and thus further streamline the operation and efficiency of the AT Plus wastewater treatment plant by adapting the WWTP management to the real inflow.
• AT PLUS wastewater treatment plants meet: Category III. or Category +P and Category +D according to the Regulation of the Government of the Slovak Republic No. 359/2022 Coll. for discharge into surface and groundwater for a source size of up to 50 EO.

• Standard model of wastewater treatment plant with MBBR technology.
• The wastewater treatment plant is equipped with an AQC MBBR GSM control unit.
• AT MBBR WWTP contains a manual air distributor, supplemented by an electromagnetic valve.
• The technology of the WWTP using a floating biocarrier (MBBR - Moving Bed Biofilm Reactor) allows for better management of inflow irregularities and stabilization of the WWTP operation.
• AT wastewater treatment plants meet: Category I. and Category II. according to the Regulation of the Government of the Slovak Republic No. 359/2022 Coll. for discharges into surface and groundwater for source sizes up to 50 EO.
