VILLAGE, BHAVANI TALUK, ERODE DISTRICT, TAMILNADU.

1. Identification of the project and project proponent/Background information

The textile sector is an important industry for the country and has been contributing to about 4 per

cent of the country’s GDP. Textile industries in Tamil Nadu are particularly spread in the districts of

Erode, Salem, Tirupur, Namakkal, Coimbatore, Karur and Madurai.

The dyeing industry in Tamilnadu is located in Tirupur, Karur, Pallipalayam,

Komarapalayam, Rasipuram, Erode, Perundurai, Bhavani, Kanchipuram, Salem and

Edappadi. These clusters have polluted the Rivers like Cauvery, Noyyal, Amaravati &

Bhavani, which in turn have polluted the Ground water, drinking water sources & have also

affected the farming operations. The situation has been aggravated by the fact that most of the

Rivers in Tamilnadu originate from the neigbouring states which are not perineal. The high

salinity in the textile effluent affects the ground water quality and soil fertility.

To solve this issue & to protect the environment, the Government of Tamilnadu announced

the grant for the Textile industry to install the pollution control facilities to treat the effluent

generating from the bleaching & dyeing operations in industries. This project is proposed

based on the Announcement made by the Honorable Chief Minister of Tamilnadu under

Rule 110 in the Legislative Assembly on 11.08.2014 for Environment Department and as

per the G.O.(Ms.) No.48, dated 31.03.2015 of E&F Department for Establishment of

Integrated Textile Processing Parks with Common Effluent Treatment Plants (CETPs)

based on Zero Liquid Discharge (ZLD) for rehabilitation of micro, Small & medium scale

textile bleaching, dyeing and its allied units in the districts of Namakkal, Erode, Salem &

Karur.

Erode district is distinctive in the state of Tamil Nadu as more than 40% of its population

depend on non-agricultural sector for its livelihood. Industries and trade naturally occupied a

prominent place in the economy of the district. Traditionally, significant industries prevalent

here were handloom weaving, carpet manufacturing, cart manufacturing, oil-pressing, brass

vessel manufacturing etc.

2 | P a g e

Bhavani Taluk in Erode district has 141 numbers of micro, small and medium scale textile

bleaching and dyeing units in cluster. The majority of these small and medium industries are

carrying out both bleaching and dyeing activities within their premises. Most of these textile

units are located between the two rivers, viz. Bhavani & Cauvery. As these units are water

and chemical-intensive, it requires adequate care to treat and dispose or recycle the effluent in

an environmentally sustainable way.

Among 141 numbers of bleaching and dyeing units in the Bhavani cluster, 73 Nos. of non-

consented industries which are under closure joined together and proposed to install the ZLD

based Common Effluent Treatment Plant at Aandikulam village, Bhavani Taluk, Erode

District in Tamilnadu.

They have formed an association namely, ‘Sree Bhavani Dyeing Cluster Development.

Limited’ and incorporated under the companies Act, 1956 (No.1 of 1956). They proposes to

set up a 4.0 MLD capacity ZLD based Common Effluent Treatment Plant R.S.F

Nos:14/9,11/1,13/5,13/2,13/2,14/7,13/3,13/4,14/8 (Latitude11°27'47.31" North and

Longitude 77°40'38.79"East) at Aandikulam Village, Bhavani Taluk, Erode District,

Tamilnadu. The Recovered products like recovered water, treated Brine solution &

Recovered salt will be used in the member dyeing industries at an estimated cost of Rs. 92.21

crores.

The projected employment, direct and indirect, post commencement of operation is about

1300.

2. NEED FOR THE PROJECT

Tamilnadu is a severely water stressed state. Most rivers in the state are monsoon fed and

remain dry for most part of the year. In addition to this, almost all major rivers originate from

neighboring states such as Karnataka, Kerala and Andhra Pradesh with all of whom the state

is facing ‘water sharing disputes’.

Most of the textile units are located between the two rivers, viz. Bhavani & Cauvery and are

water and chemical-intensive requiring adequate treatment to dispose or recycle the effluent

in an environmentally sustainable way.

Eighty two units, according to TNPCB, are non-consented and have attracted the G.O, TN

E&F G.O No.’s 213 dated 30.03.1989 and 127 dated 08.05.1998, which restricted

3 | P a g e

establishment of new polluting / red category industries, like the bleaching & dyeing

industries within a radius of 1 km from any of the water bodies & 5 km of the Bhavani &

Cauvery rivers respectively and as these units have come up after the G.O., TN G.O.’s 213

and 127 became effective.

Out 82 non-consented units closed by TNPCB due to non-compliance, 73 have joined

together and formed an association and willing to install a zero-liquid discharge based CETP

with recycling of treated effluents for their unit operations and to ensure their environmental

sustainability.

This will maintain livelihood of over 5000 population that largely depend directly or

indirectly on this cluster of units. It will help in cleaning of Rivers and Lakes, an objective of

the Government and public alike.

The list of member units of Sree Bhavani Dyeing Cluster Development Ltd. and their

estimated share of effluent discharge capacity to the CETP is given in Table:1

6 | P a g e

The proposed Sree Bhavani Common Effluent Treatment Plant (SB CETP) at Bhavani

includes the following major components:

1. Common effluent conveyance system comprising of individual connections, gravity

mains and pumping mains with intermediate pumping stations

2. Common Effluent Treatment, Recycling and Zero Liquid Discharge Plant of 4.0 MLD

capacity to treat and recover the combined effluent from all the 73 bleaching and

dyeing units under M/s. Sree Bhavani Dyeing Cluster Development Ltd into reusable

grade water and to separate out salts from the water and use the same back in the

member dyeing units or can be sold out.

3. The power and steam requirements for the ZLD based CETP will met through Solar

Thermal System. for Reject Management System (RMS) and through third party

Power Purchase Agreement (PPA) for Power requirement.

4. Chemical sludge so formed in the CETP has potential to use it as raw material in the

cement manufacturing and would be supplied to cement industries with prior

authorization from TN PCB, for which the MOUs will be executed.

5. Bio-sludge so formed in the CETP has potential to use it as auxiliary fuel by making it

as briquettes.

1.4 PROCESS DETAILS

Textile dyeing effluent generating from the member dyeing industries will be treated in the

proposed ZLD based CETP and the recovered water will be recycled back to member

dyeing units through closed underground pipeline. The recovered brine solution and sodium

sulphate salt shall be utilized in the member dyeing units. Thus, making the system zero

waste salt (ZWS). It is estimated that more than 98.5%of water will be recovered from the

effluent during the treatment process (about 94-95% as recovered water and about 3.5 –

4.0% as treated Brine solution) and reused in the dyeing process.

5. QUALITY OF INFLUENT AND RECOVERED WATER

The untreated effluent from the dyeing units is alkaline in nature and COD and BOD are in

the range of 600-1000 mg/l and 300-500 mg/l respectively. Post biological treatment, the

BOD and COD would be reduced to <5 mg/l and <250 mg/l respectively. Hardness is also

present in the treated effluent in the range of 100-150 mg/l. After Ion exchange process,

this will be reduced to< 5 mg/lit. The quantity and quality of recovered salt is given in

table:3

Water recovered from the RO system will be having the TDS in the range of 100-250 ppm.

Liquid brine after treatment would be sent to the member units for reuse and would have the

pH in the range of 5.0-5.5, Total hardness and Alkalinity would be in the range of 150-200

mg/l and <200 mg/l respectively.

Sodium sulphate recovered from the adiabatic chiller would have purity in the range of 97-

98%w/w and other than sulphate; chloride is also present in the range of 1-1.2%w/w. The

sludge generation and disposal at the proposed Sree Bhavani CETP is given in table:2

7. ELECTRICAL POWER REQUIREMENT

The total estimated electrical power for operating the 4 MLD capacity ZLD based CETP is

2.00 MW (Operating load). The power supply for the ZLD based CETP shall be obtained

through a long-term Power Purchase Agreement (PPA) to be entered with a third party and

would be wheeled through TANGEDCO (State Electricity Board) with 22KV HT feeder.

As a 100% stand-by, a 2 No.’s x 1010 KVA DG set has been considered to operate the

CETP.

8. PROPOSED INFRASTRUCTURE

Underground Piping Network

The underground pipe system comprises of a combination of 80% gravity pipeline and 20%

pressure (pumping) pipeline network for collecting effluent generated from the individual

units. These pipelines need to be corrosion resistant

The proposed Collection & Conveyance network comprises of the following:

a) Untreated or raw effluent collection and conveyance network is about 11.56 km

from the individual industries to the CETP.

b) Recovered water conveyance system for return of recovered water from CETP to

individual industries- (about 10.46 km)

c) Recovered brine solution from CETP to member units - (about 10.46 km)

1.10 EMPLOYMENT GENERATION DUE TO THE PROJECT

As these textile bleaching & dyeing industries were closed by TNPCB, a decade before due

to the non-availability of treatment facilities and non-availability of valid consent for the

industries and the owners of these closed textile dyeing industries are currently working as

workers in other Textile dyeing industries. With the regeneration of these industries through

the consent from TNPCB, the livelihood in the region will be revitalized.

The CETP will generate employability of around 40 people for O&M and during

construction period, the local people will be hired. While the project itself would give direct

employment to around 20 persons and indirect employment to over 60 persons, it would

overall additionally provide a sustainable employment to over 1000-1300 people both

directly and indirectly in the member units.

18 | P a g e

9. REHABILITATION & RESETTLEMENT

There is no land acquisition and no displacement in the project. The land is in the

possession of the association. It is a open vacant dry land. Hence rehabilitation and

resettlement is not required.

10. PROJECT SCHEDULE AND COST ESTIMATES

It will take 18 months to complete the project from “zero day”, after getting all statutory

approvals. The estimated cost of the project is Rs. 92.21 crores.

11. ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)

With the setting up of zero liquid discharge based CETP with the provisions of recycling

treated waste water, recovered salts to the member units and use of chemical sludge by

cement industries and biological sludge as auxiliary fuel will have positive impacts on

environment. It will help in opening the closed micro, small and medium textile industries

in the area resulting in direct and indirect employment to the locals. This project not only

conserves the natural resources but also provide inclusive sustainable growth. Hence this

project is suggested for EC.

Executive Summary

1) Introduction of the project/Background information:

The textile sector is an important industry for the country and has been contributing to about 4 per

cent of the country’s GDP. Textile industries in Tamil Nadu are particularly spread in the districts of

Erode, Salem, Tirupur, Namakkal, Coimbatore, Karur and Madurai.

The dyeing industry in Tamilnadu is located in Tirupur, Karur, Pallipalayam,

Komarapalayam, Rasipuram, Erode, Perundurai, Bhavani, Kanchipuram, Salem and

Edappadi. These clusters have polluted the Rivers like Cauvery, Noyyal, Amaravati &

Bhavani, which in turn have polluted the Ground water, drinking water sources & have also

affected the farming operations. The situation has been aggravated by the fact that most of the

Rivers in Tamilnadu originate from the neighboring states which are not perineal. The high

salinity in the textile effluent affects the ground water quality and soil fertility.

To solve this issue & to protect the environment, the Government of Tamilnadu announced

the grant for the Textile industry to install the pollution control facilities to treat the effluent

generating from the bleaching & dyeing operations in industries. This project is proposed

based on the Announcement made by the Honorable Chief Minister of Tamilnadu under

Rule 110 in the Legislative Assembly on 11.08.2014 for Environment Department and as

per the G.O.(Ms.) No.48, dated 31.03.2015 of E&F Department for Establishment of

Integrated Textile Processing Parks with Common Effluent Treatment Plants (CETPs)

based on Zero Liquid Discharge (ZLD) for rehabilitation of micro, Small & medium scale

textile bleaching, dyeing and its allied units in the districts of Namakkal, Erode, Salem &

Karur.

Erode district is distinctive in the state of Tamil Nadu as more than 40% of its population

depend on non-agricultural sector for its livelihood. Industries and trade naturally occupied a

prominent place in the economy of the district. Traditionally, significant industries prevalent

here were handloom weaving, carpet manufacturing, cart manufacturing, oil-pressing, brass

vessel manufacturing etc.

Bhavani Taluk in Erode district has 141 micro, small and medium scale textile bleaching and

dyeing units in cluster. The majority of these small and medium industries are carrying out

both bleaching and dyeing activities within their premises. Most of these textile units are

located between the two rivers, viz. Bhavani & Cauvery. As these units are water and

20 | P a g e

chemical-intensive, it requires adequate care to treat and dispose or recycle the effluent in an

environmentally sustainable way.

Among 141 bleaching and dyeing units in the Bhavani cluster, 59 are TNPCB consented and

82 are non-consented units. The latter units were closed by TNPCB due to non-availability of

valid consent and are not in operation for more than a decade due to their inability to invest to

install the proper effluent treatment facilities.

Among these TNPCB non-consented textile bleaching & dyeing industries, 73 units have

joined together and formed an SPV, namely, M/s. Sree Bhavani Dyeing Cluster Development

Limited’ and incorporated under the companies Act, 2013. They proposes to set up a 4.0

MLD capacity ZLD based Common Effluent Treatment Plant (CETP) Sree Bhavani

Common Effluent Treatment Plant with zero liquid discharge at R.S.F

No:14/9,11/1,13/5,13/2,13/2,14/7,13/3,13/4,14/8, (Latitude11°27'47.31” North and Longitude

77°40'38.79"East ) and to recycle the treated effluents in their units at an estimated cost of

Rs. 92.21 crores.

The projected employment, direct and indirect, post commencement of operation is about

1300.

2) Project Description.

The proposed ZLD based Common Effluent Treatment Plant (CETP) by M/s. Sree Bhavani

Dyeing Cluster Development Limited for cater its member units at Kadayampatti, Bhavani

includes the following major components:

1. Common effluent conveyance system comprising of individual connections, gravity

mains and pumping mains with intermediate pumping stations

2. Common Effluent Treatment, Recycling and Zero Liquid Discharge Plant of 4.0 MLD

capacity to treat and recover the combined effluent from all the 73 bleaching and

dyeing units under M/s. Sree Bhavani Dyeing Cluster Development Ltd into reusable

grade water and to separate out salts from the water and use the same back in the

member dyeing units or can be sold out.

3. The power and steam requirements for the ZLD based CETP are met through Solar

Thermal System for Reject Management System (RMS) and through third party

Power Purchase Agreement (PPA) for Power requirement.
