Tutorial 5&6: 1. A trickling filter has a diameter of 20 m and a depth of 2.5 m. It is operated with a direct recirculation ratio of 1.0‚ and the influent sewage flow rate is 3 ML/d. Influent BOD to the primary tank is 200 mg/L‚ and the BOD removal efficiency in that tank is 35 percent. Compute the organic load on the trickling filter. 2. A grit of specific gravity 2.8 flows into a grit chamber‚ 1.5-m wide‚ 10.5-m long and 2.5-m deep. The flow-rate of wastewater into the chamber is 2 m3/s.

Rotary kiln is a kind of high temperature drying system‚ and the main role of rotary kiln in the production process is used for production and processing of material‚ but after production and processing of the material‚ a lot of dust will not only cause harm to operator’s body‚ and can cause some to air emissions‚ such as air pollution‚ large amounts of dust particles floating in the air can cause serious impact to the quality of the air‚ long inhalation of such dust do certain harm to human body

Assam faces huge power crisis Guwahati: Assam is facing a severe power crisis after a fall in the generation of power by hydel and thermal power stations. Two transmission towers in neighbouring West Bengal were damaged by a devastating storm‚ which has also led to the shortage. The state is facing a shortage of 403 Megawatt (MW) of power with the peak load hour power demand being 1100 MW as against the available 497 MW‚ official sources said today. The problem has been further compounded

Bubbling fluidized bed boiler or Circulating fluidized bed boiler? Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone. The fuel is in contact with the particles

Due to increasing competition in the field of medical testing it has become prudent for Laboratorio De Analisis Argentina (LAA) to evaluate its process and identify strengths and weaknesses to improve the operations of their laboratories. An in-depth investigation into day-to-day‚ step-by-step breakdown of activities has uncovered where‚ and how LAA can achieve efficient operations. From the original collection of samples to the final step of communicating the test results to the patients‚ LAA

How would I market a slime product and make money doing so? After making four different types of slime‚ I decided that I would want to market the boogers. I choose this slime because it is very stretchy and not sticky. Also because this slime can be played with in many different ways. For example‚ you could blow a bubble using your hand. This slime is not a runny watery type of slime. It can be played on most hard surfaces and can be cleaned up easily. To sell this slime I would have to complete

How process control system help manages the plant operation? (Start from process raw material fed into the process to its final state of production.) Process control system must be installed to make sure that distillation column to operate well for achieving required production rates and product quality. Current application for distillation control is based on linear controller such as Proportional (P) and Proportional-Integral-Derivative type controller. Each column has a control system
