You are charged to treat industrial wastewaters such as tannery wastewater and pulp mill effluents carrying hazardous wastes.
1) How can you enhance the biodegradation of these wastewaters? List all possible options available.
2) What would be a major component of pulp mill effluents? Suggest a microorganism which may be effective in degradation of the major component.
3) What is a possible degradation mechanism for this biodegradation by the microorganism?

A pulp mill utilizing the saw dust
from nearby lumber mills to produce a market pulp for paper
production. A recent development had the company thinking of
increasing the pulp production by 50% for entering the nonwoven
market. A close examination at the pulp mill has the engineers to
conclude that the digesters were the bottleneck. Currently, the
woodchips were steamed, mixed with a pulping liquor and underwent
delignification at 150°C for 3 hours. For each load of woodchips, a...

A new wastewater treatment plant was built to treat the
wastewater flow 800,000 gpd. The capital cost to build the
wastewater treatment plant was $6,000,000. The annual operation and
maintenance costs of operating the plant is $700,000/year. Estimate
the cost of treating 1000 gallons of wastewater ($/1000 gallon).
Assume the design life as 20 years and interest rate of 4%.

Suppose a pulp and paper mill emits pollution into a river
upstream of a commercial fishing operation. The emissions from the
mill damage the fishery by reducing the number of fish that can be
caught. The mill benefits from emissions as these are a by-product
of pulp and paper production.
Explain why the pollution level under point (b) is not an
efficient outcome. What is the efficient level of
pollution? Explain.

A factory disposes 1.1
m3/s of treated industrial wastewater into a river. The
wastewater has an ultimate biochemical oxygen demand of 25 mg/L and
dissolved oxygen of 2 mg/L. Just upstream of the wastewater
outfall, the river has a flow rate of 10 m3/s, ultimate
biochemical oxygen demand of 6 mg/L, and oxygen deficit of 2 mg/L.
At the river temperature, the saturation concentration of dissolved
oxygen is 9 mg/L. The deoxygenation coefficient is 0.19
d-1 and reaeration coefficient is...
