Description
The ClearFox® QuickOne+ is a fully pre-assembled SBR domestic sewage treatment plant, manufactured in Germany by PPU Umwelttechnik GmbH. It is suitable for new developments, or as an upgrade to a septic tank system for houses, schools, restaurants and other commercial or domestic applications. Complete systems available for up to 24PE, and equipment kits for local tank installation for bigger populations. With add on modules for phosphorus removal and disinfection, it can be installed in sensitive areas. It is also tested and proven to have desludging intervals of more then 1 year. Thanks to an integrated pressure sensor, the QuickOne can independently adjust the aeration times. At higher inflow peaks, the system increases oxygen to enhance performance. If the inflow is low, the system switches to standby mode.
How It Works
1. Filling
The wastewater flows into the ClearFox® QuickOne. The automatic fill level measurement recognises when wastewater flows into the domestic sewage treatment plant. The cycles are then adjusted accordingly

2. Cleaning and Aeration
The system injects air into the wastewater via perforated discs at the bottom of the tank. During the aeration process, the microorganisms consume the carbon and nitrogen in the wastewater. The duration of aeration is adapted to each individual type of wastewater. The more contaminated the wastewater, the longer the aeration phase. This also ensures uniform mixing of the wastewater. The process is fully biological and does not require the addition of chemicals.

3. Settling
From the buffer tank, the wastewater flows onto a mechanical tipper tray. This fills continuously with wastewater until it tilts due to the increasing weight on one side. Thus, it distributes wastewater equally over the perforated distribution tray. All parts of the flow control and distribution system are made of durable and corrosion-free HDPE. Via the perforated tray, the wastewater flows with even distribution into the biological reactor below. This guarantees stable operation without overloading, and ensures the effluent quality is consistent.

4. Flushing
There are no mechanical parts in the wastewater. The entire wastewater movement is carried out by non-clogging airlift pumps. Before the system discharges the clean water from the system, it flushes the airlift pipes with compressed air to clean them and remove any suspended solids that have settled in them. This ensures a very low level of suspended solids in the treated wastewater.

5. Clear Water Extraction
In this phase, the system drains the treated water from the system. The system completely discharges the clean water from the upper water column. The operator can use this for irrigation or discharge it underground into the environment.
