Question

Problem Statement: A midnight dumper discharges a truck load of industrial waste in a gravel pit. Three days after the truck is spotted, a sample of the remaining pool of pure waste is collected and is sent to laboratory for forensic analyses. Test results indicate that sample has a BODs of 80 mg/L 02 with a rate constant of 0.1/day. Three nearby factories generate organic wastes: a winery (ultimate BOD = 275 mg/L Oz), a vinegar manufacturer (ultimate BOD = 80 mg/L 02) and a pharmaceutical company (ultimate BOD = 200 mg/L O2). You are the forensic expert here: Determine the source of waste.

Answer 1

Answer:- page-1 * from the data - =) Test results indicate that sample has a BODs of 80 mg/202 » Rate constant of per day - o.1 day - Three near by factories generate organic wates: ; A winery (ultimate BOD= 275 mg/202) ji, A vinegar manufactur (ultimate BOD = 80 mg/LO2) in a pharmaceutical company (ultimate 1 BOD = 200 mg/LO2). - Trunk spottled after 3 days. . Now, we find out the ultimate Bop

page-2 (B00x): - om noe annekt) :: Here we examine : (we pool o pure Bo Ds = Bobu (1-eikns) waste an xs)) calculated Bob 80 = BODu (1-.e (014) So, tos] ... BODu = 203.32 mg/L ~ 200 mg/ Now, from check from BOD value 1. It is the given sources which source ultimate matches. the pharmaceutical companie Please give me positive vote.
