Reported percentage distributions are exclusive of special and hazardous wastes. bTwenty percent of the households in the United States are assumed to have food waste grinders. Additionally, it is assumed that the percentage of food waste ground up and discharged with wastewater is 25 percent. Current (1990) recycling rate for the United States assumed to be 11 percent. Adapted in part from Ref. 10. dBased on measurements made over a five-year period (1985 to 1990) during the first two weeks of October (see Table 3-9).

Why does the uncoked coal in the refuse have the same calorific value, VCM analysis, and VCM, FC ratio as the green coal?

differences and similarities with solid and hazardous waste

A yard waste composting windrow has a triangular cross section and is 10 feet wide at the base and 10 feet high at the peak and 100 feet long. You may assume the waste has a specific weight of 400 Ib/yd^3 as placed in the windrow. The waste material is 40-percent biodegradable and has the ultimate composition of C60H95040N. Determine the amount of oxygen required to stabilize the waste (show all work for full credit). Assume the aerobic degradation can be expressed as: (4a + b - 2с + За 02 b - 3d aco, + (").

A metal plating industry produces effluent containing Cu2+, Fe2+, and Ni2+ at concentrations of 25, 25, and 35 mg/L, respectively. The wastewater flow rate averages 290 m3/d. An ion exchanger with a capacity of 3 meq/g is used to remove these metals before discharge of the waste to the sewer. The exchange capacity of the resin on a volumetric basis is 2.0 meq/L. What is the volume of the ion exchanger and the mass of resin in it to remove these ions if the resin is to be regenerated once per week?

Please upload your full solution to the following problem. Calculate the bed life, volume of water treated, minimum carbon usage rate (CUR), and maximum specific throughput for trichloroethene (TCE) given the following design specifications: ● . B Influent concentration = 1 mg/L TCE Carbon type: Calgon Filtrasorb 400 (12 x 40 mesh); Pb = 450 g/L Freundlich parameters for TCE Freundlich capacity parameter K = 55.9 (mg/g)(L/mg)1/n Freundlich intensity parameter 1/n = 0.48 Treatment objective = 0.005 mg/L TCE Flow rate = 378.5 L/min (100 gal/min) Empty bed contact (EBCT) = 10 min . ● Assume that no other solutes compete with TCE for adsorption onto the GAC, and that the GAC is saturated at the influent concentration. 201 4 He de dis
