Integrated Solid Waste Management

Integrated Solid Waste Management (ISWM) is a thorough waste suppression, compost, removal and recycling Program. An effective ISWM system considers how to suppress, manage and recycle solid waste in a manner that is most efficiently to protect human health and the surrounding. ISWM system requires evaluation of public wants and demands and then selecting and merging the most effective waste management activities for the proposed demands. The main ISWM activities for solid waste management are Waste prevention, Recycling and Composting, and Combustion and Removal and waste collection in a properly planned, constructed, managed and mitigated landfill areas. Each of these requires careful designing, financing, accumulation, and delivery of activities.

5) The town of Camp Verde has been directed to upgrade its primary Wastewater 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 of the aeration tank.
1. BOD; of the effluent suspended solids is 70% of the allowable suspended solids
concentration.
2. Growth constants values are estimated to be: K=100 mg/L BOD5; ka = 0.025 d-1; μm
= 10 d-1; Y=0.8 mg VSS/mg BOD5 removed.
3. The design MLVSS is 3000 mg/L

An industrial wastewater discharged at a flowrate of 1000 m³/d having 220 mg/l initial concentration of total suspended solids (TSS). If this wastewater is to be treated individually by one of the following processes: 1. Primary settling tank which should remove 60% of TSS. 2. Coagulation unit using 40 g ferric chloride (FeCl3) as a coagulant /m²³ of wastewater. The coagulation unit will remove 85% of TSS. Estimate the mass and volume of the sludge generated from each suggested unit. Assume the following sludge specification: Source of sludge Primary settling tank Coagulation tank Specific gravity 1.03 1.05 Moisture content 94% 92%
2. The average wastewater flow from a community of 20,000 is 125 gpcd. The 5 day, 20 deg C BOD is 250 mg/L. The suspended solids content is 300 mg/L. A final plant effluent of 50 mg/L of BOD is to be achieved through the use of two sets of identical settling tanks and trickling filters operating in parallel. The settling tanks are to be designed to a standard of 1000 gpd/^2. The trickling filters are to be 6^ deep and operated at an organic loading of 55 lbm/1000^3 d. There is no recirculalon. (1) What settling tank surface area is required? In ft^2 (2) What settling tank diameter is required? In ft (3) Estimate the BOD removal in the settling tanks? In percent % (4) What is the trickling filter diameter? In ft domeved Ward
A municipal wastewater flow of 1,000 m³/d contains 400 mg/L BOD5 and is treated to be in a trickling filter. The filter will use a plastic filter medium with a specific surface area of 200 m³/m² and will operate with a recirculation ratio of 100% and a hydraulic loading of 25 m³/m² -d. Taking both surface loading and volumetric loading criteria into consideration, what volume (m³) of plastic media should be installed?
Two circular clarifiers operated in parallel service a single stage bio-tower system (plastic media) that receives municipal wastewater at an average flow (Qaverage) of 2000 m³/d, with BOD5 = 200 mg/L. The internal flow recirculation ratio is 2.4. The maximum overflow rate for the clarifiers is 1.8 m³/m²-hr. The design procedures require that the sizing of the clarifiers be based on "PEAK" flow which is twice the average flow (Qpeak = 2 × Qaverage), and media depth in the biotower is 3.0 m. Determine: (a) The overall BOD5 removal. (b) the surface area and the diameter of each clarifier. (k = 0.06 min¹; n = 0.5),
Question- A circular primary clarifier processes an average flow of 3000 m³/d of municipal wastewater. The overflow rate is 25 m³/d. Find the diameter of clarifier.
