Effluent treatment plant is used for treated waste water which is come from different manufacturing industries where different types of chemicals and dyes are used for treated the materials. After treatment, waste water are discharge to the environment directly. This waste water is harm full for the environment. To protect the environment from the harmful effect of the waste water effluent treatment plant is used where waste water is treated and makes is not harmful to the environment.
In textile industry different types of dyes and chemicals are used in weaving, dyeing and garments washing plant. This waste water is treated in effluent treatment plant. Here I will give an idea about the biological waste water treatment plant. In dyeing process waste water is discharge from scouring, bleaching, washing and dyeing. This dyes and chemicals are supplied to the biological water treatment plant for purification.
In Bangladesh; a lots of dyeing and textile industries established for processing textile products. To protect the environment from the harmful effect of the waste water the Department of Environment, Government of Bangladesh fixed the following parameters for the waste water which will discharge in the environment after treatment.
- PH = 6-9
- BOD = 50 mg/L
- COD= 200 mg/L
- Suspended solid = 150 mg/L
- Color = Light brownish.
The waste water which is produced in dyeing industry its characteristics may be as follow:
- PH = 9-11.
- BOD = 300 mg/l
- COD = 200 mg/l
- SS = 200 mg/l
- Color = Dark
After treatment the characteristics of the waste water changed as follow:
- PH = 7-8
- BOD = 30 mg/ L
- COD = 160 mg / L
- Suspended solid = 30mg/L
- Color = Light brownish
Process flow chart of biological waste water treatment plant:
Effluent comes in collection tank
↓
Equalization tank (Cooling & Mixing)
↓
Primary clarifier tank (Neutralization)
↓
Aeration tank
↓
Secondary clarifier (Tank 1 & 2)
↓
Sludge return to aeration tank
↓
Thickness filter

Fish pond

So, that’s all about the effluent treatment plant. If you have better idea lets me know about it.

Please help me about etp.
Hi Masud,
Your vision in the field of ETP is well appriciated. Kindly share your experience in the field of fully bio logical ETP for textile dyeing units. As per my knowledge operating fully bio ETP is very difficult due to change in parameters.

Dear Textile Technologist/ Writer of this main article,
I am so sorry to say that you do not have any basic idea regarding waste water chemistry. In 3rd Paragraph of your articles, mentioned the waste water characteristics as like BOD- 300 mg/l and COD-200 mg/l. Do you exactly know what is BOD and what is COD?
The hydrocarbon(e.g. starch) which can be oxidized by micro-organism through their metabolic process can be indirectly measured by BOD. The relationship is if 23 gm oxygen is required to oxidized 12 gm carbon, so if you know the oxygen lost from the water, you can calculate the amount of carbon present in the waste water. Usually BOD is measured for 5 days period or in some cases for 3 days period or some time the ultimate BOD is also calculate.
For your information, the hydro carbon which can be metabolized by bacteria can also be oxidized by Chemical Oxidizer (such as K2Cr2O7, KMn04, H202, 03, etc.). It is also for your information, a good oxidizing agent like dichromate can oxidize 100% of organic carbon but bacteria can not metabolized all hydrocarbon (especially which is known as persistant organic matter, or long chain complex organic matter).
So, the information what I want to give you that COD value can not be less than the BOD value it can be maximum equal for very easily biodegradable compound like cooked rice. But for textile, COD will be at least 1.5 times higher than BOD. Also note, BOD is a term which the ETP designer use rather they use COD and break down it in to two parts. The term which we use at BOD is mentioned as bCOD by them. The formula is
COD= bCOD+ nbCOD where bCOD= biodegradable organic matter and nb COD non biodegradable organic matter.
So, bCOD= COD-nbCOD
I will humbly request you, not to publish any materials in public domain about which you do not have very clear understanding. You are welcome for any quarries.
Please take my sincere apology for this, my intention was not any how to personally attack you.
