A water treatment plant with an average flow of Q = 0.8 m3/s treats its water with alum at a dose of 27 mg/L. Alum (Al2(SO4)3. 14.3 H2O) coagulation is used to remove particulate matter, reduce the concentration of organic matter, and reduce the alkalinity of the water. Determine the total mass of aluminum hydroxide (Al(OH)3) consumed per day (kg/d, no decimal point) (atomic mass: Al: 27, S: 32, H: 1, O: 16).
A water treatment plant with an average flow of Q = 0.5 m3/s treats its water with alum at a dose of 34 mg/L. Alum (Al2(SO4)3. 14.3 H2O)coagulation is used to remove particulate matter, reduce the concentration of organic matter, and reduce the alkalinity of the water. Determine the total mass of alkalinity (HCO3-) consumed per day (kg/d, no decimal point) (atomic mass: Al: 27, S: 32, H: 1, O: 16, C: 12)
A family consists of an adult male weighing 70 kg, an adult female weighing 50 kg, and a child weighing 15 kg. The air they breathe contains 1 µg/m3 of a listed carcinogenic chemical, and the waste they drink contains 1 µg/L of the same chemical. Assume the air intake for adult and child is 20 m3 /day and water intake for adult and child is 2 L/day. The body retains 80% of the air pollutant and 100% of the water pollutant.
Estimate the total chemical dose per kg of body weight for each family member per day correctly.

- A county generates 1 million ton of municipal solid waste after recycling every year. The town is considering whether the waste is landfilled or incinerated. For disposal of the waste generated in one year, which option is better to produce less volume of greenhouse gases (GHGs)? Which option is better to have less greenhouse effect? We assume that the waste has a chemical formula of C68H111O50 Decomposition of solid waste in incineration is shown in the following reaction. CaHbOcNd+4a+b+2d-c2O2=aCO2↑+b2H2O+dNO↑ 2) water produced from the reaction(s) is not GHG because it is liquid water).arrow_forward3.
