Mechanical Processes

In civil engineering, the materials have to undergo a series of manufacturing processes before using them in construction and structural applications. These manufacturing processes form the foundation stone of mechanical processes. Some of the civil engineering materials such as bars, metallic beams, metallic columns, surveying equipment, earthmovers, overhead cranes, structural and construction components, and even cement that is the most fundamental construction component need to undergo different manufacturing processes before they are ready to use. These processes are mechanical.

2.40. A solution is known to contain 50 g/m³ of CH₂(CH₂),COOH and 42 g/m³ of NH3-N. Determine the theoretical ultimate carbona- ceous CBOD, the NBOD, and the theoretical total oxygen demand.
It is proposed to add activated carbon to treat a storm stream with a pollutant concentration of 5.1 mg/L. If the treatment plant has only 22 kg of activated carbon, how many liters of waste stream can be treated to achieve an equilibrium effluent concentration of 2.0 mg/L? Lab tests show that Freundlich isotherm coefficients for the activated carbon and the pollutant are K, = 0.09 L/kg and n = 2.8 for concentrations in g/L. Enter your final answer with 2 decimal places.
In a biological wastewater treatment system, which of the following conditions could beconsidered as an anoxic condition: ( )(A) [Dissolved Oxygen] = 3.5 mg/L and [Ammonia-N] = 10 mg/L;(B) [Dissolved Oxygen] = 0.3 mg/L and [Nitrate-N] = 15 mg/L;(C) [Dissolved Oxygen] = 0.05 mg/L and [Nitrate-N] = 0.1 mg/L;(D) [Dissolved Oxygen] < 0.05 mg/L and [Ammonia-N] = 10 mg/L
A Pump & Treat water treatment system at a contaminated site is designed to treat 5 m3/d of ground water in a reactor designed as a well mixed system. The effluent must meet quality standards of 25 mg/L of Iron. The treatment reactor’s 20 m3 volume is believed to be insufficient to achieve the standard. The ground water has an iron concentration of 100 mg/L and the treatment reactor has a kinetic constant of 0.5 d-1. – Confirm that the treatment system will NOT meet the effluent quality standards. – If not modify the design by adding a PFR system (using same treatment process and kinetics), what volume should the PFR addition be?
The BOD5 of the raw Divy Zeya Residential, London wastewater is 225 mg/L. A long term BOD test has revealed that this wastewater also has an ultimate carbonaceous BOD of 325 mg/L. Plant effluent testing has shown that the BOD5 drops by 92% across the plant. Long term tests on the effluent also show that the BOD decay coefficient is half the original value in the raw wastewater. Calculate the BOD decay coefficient of the raw wastewater and the ultimate carbonaceous BOD of the effluent wastewater.
An effluent stream sample (500 mL) from a metal-working facility contains 0.52 g nickel sulphate. (i) What is the nickel concentration of this effluent stream (in mg/L)?
