-A good description of what also happens at my Brother's work- waste water treatment at slaughter house/ meat processing plant.
He said he has all 3 types of Bacteria used at his plant as well.
My Brother said over the phone-
Pre treatment - floats grease and remove it.
Anaerobic treatment- decrease 75% of waste water strength.
Two types of Bacteria-
Acid formers (drop PH ) 7- 7.2 , Methane formers (convert what is left over it into methane) NOT THEIR POOP- THEY JUST MAKE IT.
need balance of the two.
Boilers at his plant are running from bacteria methane gas.
last step- U.V. disinfection system. light through water. Well there is more involved but that's the gist of some stuff.
They still do use some chlorine.
