how do you think that pH of a jar where you have added a certain
amount of the coagulant would compare with that of a jar where you
have added none?
The coagulant added is Alum, the jar contains raw water.
Homework Answers
pH of jar with coagulate will be less than 7(pH of water) as alum after ionisation produce solution acidic in nature.

A treatment plant operator would like to estimate the maximum amount of coagulant, alum Al_2(SO_4)_3 14H20, that she can add to the plant's source water (initial pH = 7.5 and initial ALK = 40 mg/L as CaCO_3) without causing the pH to drop below the minimum desirable pH value of 6.5. Assume that all added alum precipitates as Al(OH)_3(s) Al_2(SO_4)_3 14H2O rightarrow 2Al(OH)_3(s) + 3SO4^2- + 6H^+ + 8H_2O You can also assume that gas exchange during the various treatment...

We have packaged the four algorithms TwoSumFast and TwoSum, in a jar file that you can download from (https: //github.com/idl020/lab2-runningtimes/blob/master/runningtimes.jar? raw=true). Also, a simple program has been added to measure the execution |time of each of the algorithms for some given input. For example, if you want to measure the time taken by TwoSum for a file of 1000 numbers, you should run > java -jar runningtimes.jar 2sum 1000 1000 0.006 The program prints back the input size which is...

You are assigned to operate a drinking water treatment plant which has a capacity of 280 ML per day. The source water is from a river that contains a high concentration of dissolved organic carbon (DOC), (13 mg L-1) and has a high colour (60 HU) but where the alkalinity changes seasonally. In summer to winter the alkalinity is high (> 100 mg L-1 as CaCO3) and in spring after snow has melted in the mountains and the water flows...

06, (2096) A group of students have performed an experiment where they investigate how the factors: amount of water (factor A) and amount of light (factor B) influence the growth of a certain plant. Two amounts of water and two amounts of light are used, and four replicates for each treatment combination are run. The results are as follows: Amount of Water Amount of Light Amount of Water Amount of Light 15 12 15 12 10 2 a) Determine the...
