Budget Estimating

The term budget signifies a plan over the long run, generally, a year that covers the financial expenses and revenues of any organization. This budget plan is known to estimate the growth and success of any organization. Civil engineering companies utilize project budgets for estimating project costs, construction costs, and other direct and indirect costs related to the project being undertaken. Project budget is a detailed statistical tool primarily used by project managers to estimate the overall project cost. The project budget is in the form of a document that includes all the costs which are incurred during the project undertaking and after the completion of the project. Large commercial projects have the project budget estimate in the form of large detailed pieces of documents which include every cost estimate regarding man and materials. Labor costs, material procurement costs, construction costs, and operational costs are some of the costs that are incurred during the project execution and planning phase.

5 ml wastewater is added to a 333 ml BOD flask. The initial dissolved O2 concentration was 13 mg/l and final dissolved O2 concentration was 4 mg calculate the BOD?
A 25 ml of sewage water sample was refluxed with 10 ml 0f 0.25 N K2Cr2O7 solution. The untreated dichromate requires 6.5 ml of 0.1 N FAS.10 ml of dichromate solution and 25 ml distilled water , under the same condition as sample required 27 ml of 0.1N FAS. Calculate the COD of sewage.
Example (Activated Sludge Process) - Completely Mixed with Recycle A completely mixed activated sludge process, treating a municipal wastewater, has a primary clarifier effluent BOD, of 135 mg/L. The design MLSS is 3590 mg/L, and the MLVSS is 80% of the MLSS. The plant permit is for an effluent BOD, of 20 mg/L and 20 mg/L suspended solids. The effluent suspended solids have a BOD, of 0.65 mg BOD, / mg suspended solids. The underflow solid concentration (MLVSS) is 10,000 mg/L. If umax = 3.0 day, Ks 60 mg/L, Y= 0.50 mg MLVSS / mg BOD, removed, ka= 0.1 day, and the influent flow is 0.25 m/sec, determine the following: 1. The required reactor detention time, 0. 2. The reactor basin volume, V, in m³. 3. The net waste activated sludge produced each day (kg/day). 4. The mass of solids (both volatile and inert) to be wasted each day (kg/day). The return sludge flow rate the recycle ratio. 6. The F/M ratio. 7 June 2021 Dr. Dawood Eisa Sachit Biological Wastewater Treatment 47
3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows. Solids settle to the bottom of the clarifier and are carried away by a small stream of water (the waste stream). Most of the water exits the tank as treated effluent. Assume a clarifier receives a flow of 0.10 m3/s with a solid concentration of 800 mg/L. If the waste stream consists of 3% of the incoming flow and carries 90% of the incoming solids, a) what is the solids concentration in the waste stream, and b) what is the solids concentration in the treated effluent?
