The concentration of total nitrogen (TN) is reported to vary between 20 and 35 mg/L in domestic wastewater. In raw wastewater, ammonia nitrogen (NH+4 -N) is the
This study focused on hydraulic characteristics around a gear-shaped weir in a straight channel.Systematic experiments were carried out for weirs with two diffe
Experimental and theoretical studies were carried out to investigate the coupled influence of flow velocity increment and particle size on the retention and rel
Simulations of two-dimensional (2D) flow past a circular cylinder with the smoothed particle hydrodynamics (SPH) method were conducted in order to accurately de
An anaerobic baffled reactor is a system developed in recent decades and has been used as part of the treatment of high-strength wastewater.Since the function o
