Assume that DLSUD lake is 100m2 and its average height is 5ft. Wastewater that flows into the lake are the following: Food square kitchen waste 7 m3/sec; Total Dissolved Solids (TDS) is 25,000 mg/L which operates 8hrs per day CIH 5m3 /hr kitchen waste; TDS is 20mg/L which operates 4hrs per day PCH 20m3 /day diluted laboratory waste ; TDS = 40mg/L (1)Determine the volumetric flow rate of the lake water can still accommodate prior to rainfall.
A municipal wastewater treatment plant uses a circular clarifier. It receives 12 million gallons per day of wastewater. The clarifier radius is 25 ft and the depth is 29 ft. What is the detention time in the clarifier? What is the overflow rate? (1 cubic foot = 7.48 gallons)
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%
The rate of eradicating microbes through chlorination process is 0.22/min when the wastewater is flowing at a rate of 36 m3/h. If the depth of chlorination tank is 1.6 m and the width is 1.2 m, determine the required length of the tank to achieve 98% removal.
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),

The pipe carrying wastewater contains 5.5x 105 fecal CFU/liter. Determine the length of pipe required if the maximum permissible fecal coliform concentration that may be discharged is 3000 fecal CFU/L for linear velocity of 0.85 m/s. Assume that the reaction rate constant for the destruction of the fecal coliform is 0.22 per min.
