Treatment process
1. Filling and settling phase
The wastewater first flows into a preliminary chamber. This chamber is divided into a sludge tank and a buffer tank. Heavy solids and large particles settle at the bottom of the sludge tank. A baffle prevents these solids from entering the biological reactor. The buffer tank balances the incoming wastewater flow so that peak flows do not disrupt the treatment process.
2. Transfer to the biological reactor
A flow control flap regulates the flow of wastewater into the biological reactor. This floating valve restricts and controls the flow. As the water level in the buffer tank rises with incoming wastewater, the flap also rises. This allows wastewater to flow into the biological reactor. Because the flap limits the flow to a set rate, wastewater enters the reactor continuously and evenly. This ensures stable and efficient biological treatment.
3. Wastewater distribution
From the buffer tank, the wastewater flows onto a mechanical tipping device. It fills continuously until the increasing weight causes it to tip to one side. This distributes the wastewater evenly across the perforated distribution boxes. All parts of the flow control and distribution system are made from durable, corrosion-resistant HDPE. The perforated box distributes the wastewater evenly into the biological reactor below. This ensures stable operation without overloading and consistent wastewater quality.
4. Wastewater treatment
Treatment takes place in the biological reactor. The reactor contains various materials on which microorganisms present in the wastewater grow. These microorganisms multiply and break down pollutants through respiration, without the need for chemicals or additives. The biological reactor is designed so that wastewater flows slowly through the layers of media. In this way, the small wastewater treatment plant achieves complete treatment of the wastewater. The specialised media consist of durable plastic fibres and fixed bed material, both of which provide a large surface area for bacterial growth. All materials are designed to support the growth of microorganisms while providing durability and reliable treatment performance.
5. Discharge of treated wastewater
The treated wastewater collects at the bottom of the plant and flows out. Through aerobic sludge stabilisation, the plant does not break down secondary sludge. This removes the need for the regular pumping required with septic tanks and other conventional treatment systems. The treated wastewater is suitable for irrigation, infiltration into the ground or direct discharge into a watercourse. ClearFox® Nature achieves a COD of 88 mg/l and a BOD5 of 16 mg/l. These results have been certified by independent testing bodies. ClearFox® Nature is certified in accordance with EN 12566-3 and holds numerous regional approvals in other countries.
6. Aeration
Air is an important part of aerobic wastewater treatment. Microorganisms need oxygen to break down pollutants and carbon. ClearFox® Nature is aerated naturally through small ventilation openings in the system. The resulting chimney effect allows air to circulate. The design of ClearFox® Nature prevents unpleasant odours during this natural aeration process.
