If water becomes contacted with a S/S solid that has a solid (S/S) lead concentration of 7,433 mg/kg and the water and the solid reach desorption equilibrium, what do you estimate the water concentration for lead to be? Give your answer in mg/l and assume a Kd for this system of 1,200 L/kg. Again, you can assume that the water in contact with the S/S solid is at desorption (aka. sorption) equilibrium.

Water with a chloroform concentration of 0.8 mg/L is fed at a rate of 180 m3 /h to a GAC contactor that has an area of 3.75 m by 6 m and is 2 m deep. The objective of the GAC contactor is to reduce the chloroform concentration to below 0.005 mg/L. The Freundlich parameters for chloroform are K = 15 and 1/n = 0.47 when the concentrations are measured in mg/L in the aqueous phase and mg/g on the...

The town of Camp Verde has been directed to upgrade its primary Waste Water Treatment Plant (WWTP) to a secondary plant that can meet an effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a completely mixed activated sludge system for the upgrade. The existing primary treatment plant has a flow rate of 0.029 m3/s. The effluent from the primary tank has a BOD5 of 240 mg/L. Using the following assumptions, estimate the required volume...

Plateau Creek carries 5 m3/s of water with a selenium (Se) concentration of 0.0015 mg/L. A farmer starts withdrawing 1 m3/s of water from the creek for irrigation. During irrigation, the water picks up selenium from soil. One half of the irrigation water is lost to the atmosphere or infiltration to the groundwater and the other half is returned to Plateau Creek. The irrigation runoff contains 1 mg/L Se. Assume that selenium is a conservative substance (i.e., it does not...

1. Imagine you have a saturated solution of Ca(OH)2, at equilibrium, that has some undissolved Ca(OH)2 solid on the bottom of the test tube. If you add an additional scope of Ca(OH)2 to this solution will the concentration of [OH-] in the solution increase, decrease, of be unchanged? (Briefly explain and assume we let the solution reach equilibrium again) 2.

Toluene has contaminated a city's drinking water supply. An activated carbon system will be designed to remove toluene to below regulatory levels. If equilibrium is achieved between activated carbon and aqueous-phases and the concentration of toluene in the aqueous-phase is 0.010 mg/L, what will be the concentration of toluene sorbed to the activated carbon? The Freundlich parameters for toluene and the particular type of activated carbon are: K= 159 mg/g (L/mg)^1/n = 0.54. Express your answer in units of mg...

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.

The Freundlich isotherm constants (Table 13.2) and K= 190 (mg/g)(L/mg)1/n, and 1/n = 0.33. The water to be treated has a Chlordane concentration of 0.1 mg/L. Since the MCL is 0.002, you must design for an equilibrium concentration of 0.0005 mg/L. The flow rate is 1 MGD. Assume a carbon density of 30 lb/ft3, and a typical carbon column depth of 10 ft. The carbon contractors must provide one year of treatment before new carbon is needed. Specify the following:...
