Answer #1

Ans :

Sulfates if present in water in high concentration can cause potential health hazards. Less exposure to it causes the laxative effect on human , but when the concentration is higher , it can cause catharsis in males.

Ingestion of large amounts of calcium or magnesium sulfates can lead to dehydration.

Children and senior citizens are much more prone to dehydration following diarrhea caused to sulfate intake.

These sulfates in water are harsh on skin and hair as well. They strip away all the oil from hair and skin causing the skin and hair to become dry and pale.

I am diluting wastewater (ww) with creek water. Say I have an initial concentration of 10% wastewater in a bin. I have 1 liter wastewater and 9 liters creek water. I keep pouring 1 liter aliquots of creek water into this bin to further dilute. My trash bin only holds a volume of 50 liters, but I need to keep diluting. If I take out half of the total volume in my bin (to have only 25), but I keep...

Three specimens of untreated wastewater produced at a gas field had an average benzene concentration of 6.83 mg/L with a standard deviation of 1.72 mg/L. Seven specimens of treated waste water had an average benzene concentration of 3.32 mg/L with a standard deviation of 1.17 mg/L. Let μXμX represent the population mean for untreated wastewater and let μYμY represent the population mean for treated wastewater. Find a 95% confidence interval for the difference μX−μYμX−μY . Round down the degrees of...

8. A wastewater has a dissolved oxygen concentration of 2.0 mg/L and a discharge rate of 1.1 m3/s. The river into which it is being discharged has DO equal to 8.3 mg/L, a flow rate of 1.4 m3/s and a temperature of 200C. Assuming complete and instantaneous mixing, estimate the initial dissolved oxygen deficit of the mixture of wastewater and river water just downstream from the discharge point. The saturated valued of DO at 200C is 9.1 mg/L.

LC50 for a chemical is the lethal concentration for 50% of animals or humans. For example, if water contains a chemical at the LC50 concentration, 50% of the fish population in the water would die. Environment Canada collects data on LC50 concentrations. Suppose a random sample of 60 perch (a type of fish) gives a mean LC50 for DDT of 17 parts per million and a standard deviation of 5 parts per million. (a) Find a 95 % confidence interval...

Geographer David Harvey (1993) suggests that cities are 'ecosystems' created by humans, and that humans, just like bees, beavers, or elephants, transform nature and adapt "to the ecosystems they themselves construct" . These ecosystems are dominated by buildings, sidewalks, roads, etc. We can see these 'adaptations' in technologies from basic water filtration systems to complex smart city building technologies. Harvey goes on to argue that there is "nothing unnatural about New York City" If we turn this sentiment on its...

environmental engineering wastewater treatment. waste water treatment. 1- In a 2 steps cascade aeration, each step increases oxygen concentration from 10 % to 30 % of saturation level. If the initial oxygen concentration is 20 % of saturation level and minimum oxygen is required to be 5 mg/L at the end of aeration, is the system efficient or not? Show your calculations. Inlet water temperature is 15 C (Cs = 10.2 mg/L) 2- Design flocculation tanks (2 tanks, 5 compartments...
