    The readings that came in from july last
    The readings that came in from july last year (prior to drainbo) are as follows: bod – , mg/l ss – mg/l i just got the readings from last week and they are as follows: bod – , mg/l ss – mg/l ph- . clearly the drainbo has made a huge difference in our effluent! You’ll want to plug the drain at this point because there’s going to be a chemical reaction that you don’t want overflowing let the mixture sit for - minutes and then.
