An ion-exchange resin has a capacity of 1600 eq/m³. The manufacturer recom- mends that the resin be regenerated when 75 percent of its capacity has been utilized. The regeneration cycle takes I h for draining, regeneration, and flushing the bed. The contact time in the bed(s) is to be 10 min when one bed is out of service and one bed is being regenerated. The plant is to reduce the hardness of a flow of 7000 m³/day from 250 to 100 mg/L as CaCO3. Determine the total volume of resin required and the number of beds to be used. What is the frequency of regeneration which would be required?

A 1,200 gpm WTP is being designed for treating iron and manganese. The influent manganese concentration is 80 mg/L and the iron concentration is 90 mg/L. How much oxygen (mg/L DO) from aeration is needed for design? Assuming that aeration only removes 85% of Fe and Mn, how much potassium permanganate is needed (mg/L)? Design standards require 30 days of chemicals onsite. Assuming that the chemicals onside are dry, how many lbs of potassium permanganate are required? If the treatment plant is to operate two filter cells at a time, what is the required SA of each cell, assuming SOR of 2.5 gpm/sqft?
The most common type of cement is Portland cement, which is the basic ingredient of concrete and mortar. It is made of Portland cement clinker (calcium silicates, aluminium and other compounds) and other minor constituents. Portland cement clinker is produced by heating a mixture of raw materials up to 1450° C in a kiln. There are three production stages: preparation of the raw mixture, production of the clinker, preparation of the concrete. Limestone is the main raw material for the production of clinker, followed by sand, shale, iron ore, bauxite, fly ash and slag. About 2% gypsum is also added and then the mixture is pulverised. The resulting powder will react when water is added. Portland cement is commonly used to produce concrete, which is made of gravel, sand, cement and water. Blocks of cinder concrete, ordinary concrete and hollow tile are known as Concrete Masonry Units (CMU). They are larger than ordinary bricks and used for applications where appearance is not very…

The theoretical density and bulk density of a bituminous mix are 2.48 gm/cm³ and 2.39 gm/cm³, respectively. Find the air void, volume of bitumen, VMA & VFA of the mix. Assume standard value, if required.
One common issue with air strippers is scaling due to hardness in the water. Please design an excess lime pre-treatment step to remove the water hardness (determine the softening chemical addition rates [mass/hour] of Ca(OH)2 and Na2CO3) if the water chemistry is as follows [CO2] = 5 mg/l, [Ca2+] = 50 mg/L, [Mg2+] = 6.1 mg/L, [Na+] = 23 mg/L, [Alkalinity] = 150 mg/L and [SO42-] = 24 mg/L
