In-line disinfectant contactor

摘要

An in-line contactor adapted to bring about intimate contact between a disinfectant and a wastewater stream to produce a reaction between the disinfectant and pathogens effecting kills in a manner minimizing unwanted side effects. The wastewater stream is pumped through the successive stages of the contactor, the first of which is an input section having a converging nozzle that projects the stream at high velocity into a throat. The throat feeds the stream in a highly turbulent state through a mixing section, the resultant vacuum created within the throat acting to draw a disinfectant such as aqueous or gaseous chlorine from a disinfectant supply into the mixing section where it is thoroughly intermingled with the turbulent stream before the stream is discharged from the contactor through a diverging pressure-recovery output section.
