How Astrong municipal ww with soluble BOD
of 200 mill 2 20°C is treated in a bio-tower with an 5.4m
depth of plastic packing. The hydraulic loading of the raw
ww. is 0.86 m³/m² h, and the recirculation ratio is 3
The constants based on apilot-plant study arek = 0.35/hr
and n=0.39. Calculate the effluent Soluble BOOD..
Q // A residential city with a growing population of 50,000 people is
experiencing challenges related to wastewater management. The city council
has proposed building a combined wastewater treatment plant to ensure that
domestic and industrial wastewater is treated effectively, meeting regulatory
standards for discharge. The community has identified the need for an
engineering solution that considers environmental, technical, and operational
aspects.
Scenario Details:
Each person in the city consumes an average of 200 liters of water per day,
and the organic load generated per person is 40 grams daily.
The city also houses light industries that generate 0.25 million liters per day
(MLD) of wastewater with a BOD, concentration of 600 mg/L.
Environmental regulations mandate that treated wastewater discharged from
the plant must not exceed a BOD5 of 20 mg/L.
The treatment plant must be designed to operate efficiently under seasonal
temperature variations, with temperatures reaching 35°C…
