An Innovative Design for a Separate Sewer System
The Environmental Protection Agency (EPA) has stated that what was considered state-of-the-art pollution control a century ago is no longer valid today. Designers of new sewer systems must identify the problems inherited from old design concepts and try to use new technology to revisit and upgrade …

AN INVESTIGATION OF MUNICIPAL SOLID WASTE MANAGEMENT DURING THE ARBA’EEN PILGRIMAGE IN KERBALA, IRAQ
Every year, religious events (REs) attended by millions of pilgrims, take place in different holy cities around the world. However, research on municipal solid waste management (MSWM) is limited despite the reputation of REs to generate large amounts of municipal solid waste (MSW), which negatively …

The characterisation of the hydrodynamic vortex separator using residence time distribution analysis.
… This project used residence time distribution (RTD) analysis to extensively characterise the mixing regime within a model and prototype HDVS. The HDVS was operated with and without a baseflow component and with and without the sludge hopper for a range of inlet flow rates and flow splits covering …
