Q.4 (a) A new concrete bridge is to be constructed near the sea and its design has to incorporate features protecting it from exposure to marine environments. Among these, a new coating system is being proposed for concrete. You have been awarded a six-month contract to evaluate this system and materials involved. Describe the major parts of your programme, assuming that you also have access to a structure on which the coating has recently been used.

A BOD analysis was begun on Monday. Fifteen ml of waste with a DO of zero was mixed with 270 mL of dilution water with a DO of 9 mg/L. The sample was then put in the incubator. Since the 5th day fell on a long weekend (Friday) and lab personnel do not work on Saturday, the final DO did not get measured until Monday, the eighth day. The final DO was measured at 2.8 mg/L. However, it was discovered that the incubator was mistakenly set at 32 ºC. Assume k is 0.15 day-1 at 20 ºC and θ= 1.05. Determine the 5-day 20 ºC BOD of the sample. Also, what is the ultimate CBOD at 32 ºC and 20 ºC; Will it vary?

Case4: A consulting engineering company was awarded the contract for designing, preparing the specifications, and providing "field inspection services" (monitoring the construction) of a sewage treatment plant being built for a small municipality. The construction proceeded routinely to completion. The consulting company employed Engineer A, an environmental engineer experienced in wastewater treatment, to assist in the field inspection. During the final commissioning of the plant, Engineer A observed that the biochemical oxygen demand (BOD) of the effluent was frequently above the acceptable limit. Engineer A contacted the design office at his engineering company, and after reviewing the case with an environmental consultant, he soon realized that the plant had been designed for average flows, but several food-processing industries in the municipality occasionally fed "slugs" of raw sewage to the plant. The biochemical oxygen demand would increase rapidly when one of these slugs…

A pipeline was constructed of a pipe with inside diameter 101 mm and outside diameter 114 mm. On examination it was found that the wall thickness had been reduced by corrosion to about half the original value in 3.25 years. i) Estimate the rate of corrosion in mm per year. A decision has to be made on what material to use to replace the pipe. Three suggestions have been made: ii) Replace with the same schedule carbon steel pipe and accept renewal at 3-year intervals. iii) Replace with a schedule 80 pipe, outside diameter 113 mm, inside diameter 97 mm. iv) Use stainless steel pipe, which will not corrode. The estimated cost of the pipes, per unit length is schedule 40 carbon steel $6, schedule 80 carbon steel $8, stainless steel (304) schedule 40 $26. Installation and fittings for all the materials adds $17.5 per unit length. The downtime required to replace the pipe does not result in a loss of production. If the expected future life of the plant is 8 years, recommend which pipe to…
