Inside a contact tank


This is the sort of layout that can be found in a contact tank
The water has to travel round from the inlet to the pump suctions the time it takes is called the contact time & allows the chemical doses to do their job befor they get to the pumps.
This schematic is for an actual tank the contact time is about 2 hours from start to finish.

Have a look at the pictures below to see what a contact tank looks like

Under the aerator the inlet chamber


The overflow
