[ 2 ] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate ...
The EPA storm water management model (SWMM) is a dynamic rainfall-runoff-routing simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate runoff and ...
A flushing trough is a long cistern which serves several toilet pans. It is designed to allow a shorter interval between flushes than individual cisterns. Flushing troughs were commonly used in places such as schools, colleges, public toilets, factories and public buildings where repeated use of the flushing cistern was required in a short ...
