Oczyszczalnia Scieków Czajka Oczyszczalnia Czajka to najwieksza oczyszczalnia scieków w Polsce, zlokalizowana na warszawskim Tarchominie. Obsluguje ona wschodnia czesc Warszawy oraz czesc lewobrzeznych dzielnic, takich jak Bielany, Bemowo i Wola. Zaklad ten oczyszcza scieki dla prawie 2 milionów mieszkanców stolicy i pobliskich miejscowosci. Proces oczyszczania sklada sie z kilku etapów: mechaniczne oczyszczanie na kratkach i piaskownikach, biologiczne usuwanie azotu i fosforu oraz separacja osadu czynnego. Po oczyszczeniu, wody odprowadzane sa do Wisly. Dodatkowo przy oczyszczalni dziala Stacja Termicznej Utylizacji Osadów Sciekowych, która znaczaco redukuje ilosc odpadów. Modernizacja oczyszczalni, zakonczona w 2012 roku, byla jedna z najwiekszych inwestycji komunalnych wspólfinansowanych przez Unie Europejska. W ramach projektu zbudowano takze tunel pod Wisla, którym transportowane sa scieki z centralnej i pólnocnej czesci lewobrzeznej Warszawy. Czajka zajmuje powierzchnie 52,7 ha i moze przetworzyc do 435 tys. m³ scieków dziennie. Czajka Wastewater Treatment Plant Czajka is the largest wastewater treatment plant in Poland, located in Warsaw’s Tarchomin district. It serves the eastern parts of Warsaw and some left-bank districts, including Bielany, Bemowo, and Wola, processing wastewater for nearly 2 million residents of the city and neighboring areas. The treatment process includes several stages: mechanical filtration with grates and sand traps, biological removal of nitrogen and phosphorus, and activated sludge separation. After treatment, water is released into the Vistula River. Additionally, the Thermal Sludge Treatment Facility adjacent to the plant significantly reduces waste volume. Modernization of the Czajka plant, completed in 2012, was one of the largest municipal projects co-financed by the European Union. The project included constructing a tunnel under the Vistula River to transport wastewater from central and northern left-bank Warsaw. Czajka covers an area of 52.7 hectares and can process up to 435,000 m³ of wastewater per day.
What is the capacity of the facility?: 435 000 l / day
Describe the biological treatment technology used.:
The biological treatment technology used at the "Czajka" wastewater treatment plant is an Activated Sludge process, specifically a type known as BIODENIPHO. This process employs a biological reactor that uses active sludge to break down organic matter and nutrients in the wastewater. The BIODENIPHO technology enhances nutrient removal, targeting biogenic compounds in particular. Wastewater first passes through various mechanical treatment stages, including screens, sand traps, and primary settling tanks, before being pumped into biological reactors. Here, microorganisms in the active sludge break down the organic materials and nutrients, followed by secondary clarifiers that separate the treated water from the sludge. This activated sludge process effectively removes pollutants and ensures a high quality of treated effluent.
How are biosolids (sludge) managed?: At the Czajka plant, sludge is thickened, then stabilized anaerobically in fermentation chambers, producing biogas used as fuel. Dewatered sludge goes to the Thermal Sewage Sludge Utilization Station, where it’s incinerated in fluidized bed furnaces, maxi
What technology is used for disinfection prior to dicharge of treated water?: Chlorination
Who is the owner/operator fo the facility?: Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji w m.st. Warszawie
What is the website of the WWTP?: [Web Link]
How is the facility governed?: Not listed
