The treatment plant utilizes patented aerated wetland bed technology. Air distribution manifolds connected to 2 blowers are installed at the bottom of the bed, periodically delivering oxygen and supporting the growth of aerobic bacteria on the gravel. These ensure oxygenation of the treated wastewater, enhancing the overall efficiency of the system. The aerated wetland filter system also includes a control unit responsible for smooth and trouble-free plant operation. In aerated constructed wetlands, extra oxygen is supplied to the root bed via FBA® technology (forced bed aeration), which can boost treatment efficiency by up to tenfold and decrease footprint requirements by 4–6 times. Aeration ensures a higher, more consistent level of purification and flexibility in handling variable organic loads. The ECOair filter bed is filled with media providing a substrate for bacteria, which thrive on it and proliferate by actively removing contaminants from the wastewater. The bacterial activity in their natural habitat is reinforced and multiplied by the oxygen delivered to the filter bed. High-grade waterproofing at the bottom of the bed prevents untreated wastewater from leaching into groundwater. The relatively long retention time of the wastewater in the filter bed results in negligible sludge production in the filter system, as sludge serves as food for bacteria. The combination of aerobic and anaerobic processes creates diverse bacterial populations specializing in breaking down various types of contaminants. Consequently, the bacteria can eliminate even highly persistent substances, such as pharmaceuticals and drugs. Compared to conventional activated sludge systems, electrical power consumption with the ECOair system is substantially lower, as it requires far less aeration. The facility connected to the plant exhibits highly fluctuating load patterns – fully booked on weekends, while weekday occupancy drops to under 10%. Despite this, the treatment plant achieves outstanding results in degrading contaminants from wastewater.
