Concept explainers

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

2. Families in a community in a developing country use large, 200.0 L drums to un-treated surface water. You are designing a device that is designed to dose the volume with a coagulant, stir to allow flocculation, then add chlorine tablets to disinfect the water. The water is 25 °C and initially contains 1.0E+09 particles per L. The initial particles can be assumed to be spherical, 15.0 micrometers in diameter, and with a density of 1.675 g/mL. a. If the drums have a diameter of 572 mm, how long will it take for the particles to completely settle without any coagulation or flocculation? (answer in seconds) You have determined that you can achieve complete destabilization of particles by achieving an ionic strength of 0.01 M or higher. If you use alum (Al2(SO4)3) as a coagulating agent, what mass of alum must be added per batch of 200 L? (answer in grams) How many joules of energy would be required to stir the drum at a mixing intensity of 150 s-' for 20 minutes? If the drum is stirred…

1. Water is frequently disinfected with chlorine gas, forming hypochlorous acid (HOCI), which partially ionizes to hypochlorite (OCI) and hydrogen ions as follows: HOCI H+ + OCI- The concentration of HOCI, which is the desired disinfectant, depends on the water pH. a) Write the equations to express the two ionization fractions for HOCI, that is, ao and ai. b) Plot ionization fractions vs pH, clearly identifying a regions and pKa, at 25 °C. c) Plot speciation of HOCI vs pH (log[OCI] vs pH) for a Croci-= 0.05, clearly identifying regions and pKa, at 25 °C.
