In the treatment of waste water the process generally done are
- Priliminary treatment
It includes screening, grit chamber and skimming tank
- Primiary treatment
It includes sedimentation type I and type II
- Secondary / Biological treatment
Biological treatment is of two types Aerobic treatment and anaerobic treatment. genenrally any one of the treatment is adopted.
- Tertiary / Advanced treatment
This includes chlorination process
When it comes to the treatment of waste water from pulp and paper industry the treatment like Priliminary treatment and Primiary treatment are the same of that of general waste water treatment.
Secondary treatment done in the case of pulp and paper industry is aerobic treatment, anaerobic treatment is done in case of recycle paper mills.
Tertiary / advanced treatment in the pulp and paper industry consists of biological membrane reactors, ozone treatment and membrane filtration techniques such as ultra- or nanofiltration and reverse osmosis.

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 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%.

A wastewater treatment plant that treats wastewater to secondary
treatment standards uses a primary sedimentation process followed
by an activated sludge process composed of aeration tanks and a
secondary clarifiers.
This problem focuses on the activated sludge process.
The activated sludge process receives a flow of 15 million
gallons per day (MGD).
The primary sedimentation process effluent has a BOD5 concentration
of 180 mgBOD5/L (this concentration is often referred as S). Before
flowing into the activated sludge process, the primary...

A municipal wastewater treatment plant discharges 20,000 m3/d of
treated wastewater to a stream. The wastewater has a BOD5 of 30
mg/L with a k1 of 0.23 d-1. The temperature of the wastewater is 20
oC, and the dissolved oxygen is 2.0 mg/L. The stream just above the
point of wastewater discharge flows at 0.65 m3/s, has a BOD5 of 5.0
mg/L, and is 90% saturated with oxygen. The temperature of the
stream is also 20 oC. After mixing, the...

Your task is to build a wastewater treatment plant to handle all
of the domestic wastewater produced by a housing estate. Using
population equivalent, PE = 65000, design, describe and calculate
briefly the sizes of all the unit processes in the treatment plant
that are going to be built. You may assume the value that is not
given.

A municipal wastewater treatment plant is designed for COD
removal and nitrification. The wastewater characteristics and
kinetic coefficients are described in the table below. The aeration
tank DO concentration is 2.0 mg/L and MLSS concentration is 2500
mg/L. The temperature is 15C. Assume that the concentration of
influent NH4-N that is nitrified accounts for 80% of influent TKN.
Calculate the following parameters as a function of SRT (i.e.,
derive mathematical expressions of the following parameters as a
function of SRT,...
