Setting up Low G experiment. #24

Open Roswell-Lo opened 6 years ago

Roswell-Lo commented 6 years ago

We set up Procoda to change pump speed.

Currently starting experiment today to run at 600 mL/min for 2 seconds after every 1 hour of running at 190 ml/min. (coag dose at 1.4 mg/L).

Starting Experiment today. Pump fast value at .4 (880 mL/min) , Pump fast time = 10 seconds.

Thursday experiment successful - notes weird green line (will post data/graph).

Data from 7/14 experiment Pump fast value at .5 , Pump fast time = 10 seconds.

Increase in max pressure difference hypothesized to be due to flow accumulator increasing water volume (losing air?). We tightened the cap and will observe to see if we see this increase again.

Experiment at .288 (600 ml/min) for 2 seconds. did not work.

Experiment at .5 (1120 ml/min) for 10 seconds every hour worked Experiment at .40 (880ml/min) did not work.
Experiment at .45 (1000ml/min) worked Starting Experiment at .425. (940 ml/min)

Experiment at .425 did not work.

We are using .45 (1000 ml/min) as the lowest speed needed to prevent PACl buildup.

Next experiment being started today: .45 (1000 ml/min) shortening the duration from 10 seconds to 7.5 seconds.
