3.0 RESOURCE REQUIREMENT:

3.1 Water Requirement:

Total water requirement for the proposed project will be 100.0 KL/Day, which will be

fulfilled by Borewell of Dholi Integrated Spinning Park Limited (DISPL). DISPL has

already obtained permission for abstraction of ground water through bore well from

Central Ground Water Authority (CGWA).

Generation KL/Day

1. Domestic 10.0 80.0

2. Industrial (CETP) 90.0 Nil

Total Industrial + Domestic 100.0 8.0

Domestic sewage generation @ 8.0 KL will be discharged into Common Sewage

Treatment Plant of Dholi Integrated Spinning Park Limited (DISPL) for treatment and

disposal.

Industrial water consumption will be only for chemical solution preparation and chemical

dosing, which will goes along with industrial effluent.

After treatment entire quantity of treated water will be utilized on land for gardening /

horticulture purpose within spinning park premises.

4.2 Effluent Treatment Scheme:

PRIMARY TREATMENT

BAR CHAMBER (with Mechanical cleaning screen)

The raw effluent generated from different industries will be passed through Inlet

chamber followed by bar screen. Mechanical & Manual operated bar screen shall be

provided

EQUALIZATION TANK

After screening, the overflow of screen chamber will be collected into Equalization

tank, wherein Triton Mixer with Blower shall be provided for proper homogenization

of collected effluent.



FLASH MIXER AND NEUTRALIZATION TANK

The effluent from equalization Tank will be pumped to flash mixer followed by

neutralization tank / flocculation chamber, where neutralize the effluent. The pH

measurement shall be monitored on on-line pH meter.

For proper mixing of chemicals, air shall be provided by means of Air Blower & HDPE

air grid (Coarse bubble type).

PRIMARY CLARIFIER

The effluent shall be routed under gravity to primary clarifier. Clarifiers are

extensively used for continuous removal of settle solids from effluent by mechanical

sludge scrapper.

The sludge removal mechanism revolves slowly and scraps with settled solids at the

bottom. The clarified effluent overflows will be routed under gravity into the Aeration

Tank. The excess sludge shall be drained to sludge collection tank. After collection of

the sludge, it will be pumped to thickener for dewatering of sludge.

02. BIOLOGICAL TREATMENT

AERATION TANK-I / II (Three Compartments Each) (by Diffused Aeration)

The Clarified effluent overflows from primary clarifier will be routed under gravity to

the series of two aeration tanks in parallel.

In aeration tank, micro-organisms will be present in the suspended form to oxidize

the dissolved organic contents in the effluent. In aeration system, organic content in

effluent degraded by aerobic condition and organic matter get converted into CO2

and H2O. On-line DO meter shall be installed and connected to control room for

indication & rectification if required if any.

Diffused Aeration will be provided in Aeration tank for maintaining MLSS, Dissolved

Oxygen and for continuous mixing of effluent in the aeration tank. Aerobic condition

in aeration system will be maintained by means of the diffused aeration

SECONDARY CLARIFIERS I & II

The effluent from both the aeration tanks will be routed under gravity to secondary

clarifiers. Clarifiers are extensively used for continuous mechanical removal of

settable solids from effluent. The sludge removal mechanism revolves slowly and

scraps with settled bio-solids at the bottom. The settle sludge shall be partly recycled

into aeration tank to maintain MLSS concentration.



The sludge shall be drained into sludge collection sump provided near the secondary

clarifier for recycling back into the aeration tank. Excess sludge generated shall be

drain into the sludge collection Tank.

INTERMEDIATE COLLECTION TANK/CHLORINE CONTACT TANK

The overflow of secondary clarifier i.e. treated effluent will be collected in the

intermediate collection tank. The Chlorination will be done by Gas Chlorinator. Gas

Chlorinator will be used for disinfection of microbiological organism like Algae, fungus

& E-coli etc.

Treated effluent from intermediate collection tank will flow for teartiary treatment.

03. TERTIARY TREATMENT :-

Sand Filter - 2 No’s

The treated effluent from guard pond containing suspended matter passed through a

filtering medium to effectively remove the suspended Impurities.

Activated Carbon Filter – 2 No’s

Activated carbon filters are provided for de chlorination &removal of organic

impurities from water.

04. SLUDGE DRYING BEDS

The sludge generated from primary and secondary clarifier will be collected into

sludge drying beds for drying purpose through sunlight. Leachate from SDBs will be

go to collection tank.

The dried sludge shall be packed in HDPE bags and stored into sludge storage Room &

Disposed off at authorized TSDF site.



4.3 Hazardous Waste Management System:

There will be generation of hazardous waste like ETP sludge from common effluent

treatment plant, used / spent oil form plant machineries and discarded bags / containers /

barrels / liners, which will be disposed as per Hazardous Waste (Management, Handling

& Transboundary Movement) Rules – 2008.

The total quantity of Hazardous Waste will be stored within the premises in an isolated

storage area having proper roofing, flooring and leachate collection system.

The details of hazardous waste generation and its disposal are as given below.

4.4. Green Belt Development:

Company will develop an effective green belt @ 5,000 Sq. Meter within the CETP and

on periphery of the premises.

In addition to this, majority of the vacant land will be planted with trees, shrubs and

grasses.



5.0 CONCLUSION:

M/s. Dholi Integrated Spinning Park Limited (DISPL) is going to set up new proposed

Ahmedabad – 382240 for installation and operation of Common Effluent Treatment

Plant having capacity @ 5.0 MLD Capacity.

The proposed project will be developed within integrated Spinning Park having NA land

and all the necessary infrastructure and facilities.

Industrial wastewater will be treated in adequate CETP and then whole quantity of

treated effluent will be utilized on land for gardening / plantation purpose after achieving

permissible norms.

There will be no air emission from proposed project.

Hazardous waste will be stored in dedicated storage area having appropriate facility and

disposed as per HW (M, H & TM) Rules – 2008.

There is no habitation on the proposed project area and it is industrial land which is

purchased by company for development of Company, so R & R policy is not applicable

to this project. There shall be no displacement of any population in project area.

Total area of the project will be 23,040 Sq. Meter, from which 5,000 Sq. Meter area will

be developed as green belt area.
