Abstract: The present invention relates to an apparatus for enhancing hydraulic pre-aeration and detention time efficiency in closed pipe sewer systems. The apparatus is configured for in-pipe installation and utilizes the kinetic energy of flowing wastewater to drive a piston-crank mechanism comprising a piston (201), crank (202), and connecting rod (203). The reciprocating motion of the piston induces controlled flow modulation, resulting in increased hydraulic detention time within the pipe. The propellers (101) are positioned within the flow path and rotates in response to wastewater flow, generating turbulence and promoting mixing. The combined effect of flow pulsation and turbulence facilitates passive oxygen transfer from trapped air into the wastewater, thereby improving dissolved oxygen levels. The apparatus further includes an electronics housing module (102) configured to monitor parameters including pH, turbidity, and overflow conditions, and to transmit data through an IoT- enabled communication system. Components of the apparatus are fabricated using Acrylonitrile Butadiene Styrene (ABS) through 3D printing, providing corrosion resistance and reduced weight. The piston (201) and propellers (101) are provided with a zeolite-based coating to adsorb odor-causing compounds. The invention reduces biochemical oxygen demand (BOD), chemical oxygen demand (COD), and odor generation, thereby improving wastewater quality prior to downstream treatment (Figure 1).
