The article describes an effective method of wastewater treatment generated during the operation of the multifunctional marine transshipment complex «Bronka». The presented scheme allows to significantly increase the concentration of activated sludge in such a circuit (up to 20 g/l instead of 6 g/l in traditional aeration tanks), which ensures a more intensive biological treatment process. The most significant advantage is that during purification, water passes through the pores of ultrafiltration membranes up to 100 nanometers in size. At the indicated filtration mode, the water after purification has a turbidity of no higher than 2.5 mg/L.
