ZLD (Zero Liquid Discharge)

GETP is having Environmental Clearance for 100 MLD Common Effluent Treatment plant (CETP) including recycling facility and 60 MLD CETP is commissioned in JULY 2009 and operating successfully. GETP will be having upcoming 25 MLD ZLD project under IPDS scheme of Ministry of Textile, GOI, India. GETP –CETP will be upgraded and is going for Installation of 40 MLD CETP and tertiary treatment to 25 MLD ZLD plant.

ZLD (Zero Liquid Discharge) – means zero discharge of wastewater from Industries. A ZLD system involves a range of advanced wastewater treatment technologies to recycle recovery and re-use of the 'treated' wastewater and thereby ensure there is no discharge of wastewater to the environment.

The Proposed ZLD system comprises of the following components:

  • Pre-treatment (Tertiary Clarifier, Disc Filter, Ultra filtration, etc..)

  • Reverse Osmosis (High pressure RO & Nano-filtration)

  • Reject Management (MVR Evaporator & Crystallizer)

The Treatment scheme is based on Physico-Chemical treatment followed by Activated sludge process (Sequential batch reactor) at CETP. Thereafter in ZLD the tertiary treatment includes Ultra filtration system and Reverse Osmosis, MVR Evaporator and Thermal crystallizer system.

Disposal of sludge/reject salt recovered as hazardous waste from the plant will be sent to government authorised waste disposal site or recycler. Treated water will be used as industrial grade process water for processing units of GETP.


The Project for ZLD with this scale and size is perhaps the first of its kind in India. Key benefits of the project are:

  • Recycling > 98% of water

  • Reuse of > 90% of salt

  • Cleaning of the local Environment

Identify ways for improving effluent quality. Identify technology for water conservation.

Installing ZLD technology is therefore often beneficial for the plant’s water management; encouraging close monitoring of water usage, avoiding wastage and promotes recycling by conventional and far less expensive solutions.

High operating costs can be justified by high recovery of water (>90- 95%) and recovering of several by products from the salt.

Reduction in water demand from the Industry frees up water for Agriculture and Domestic demands.

Environmental Clearance recommends re-circulating and reusing the treated waste water within the process plant/park to conserve the water. A more sustainable growth of the industry while meeting most stringent regulatory norms.

Common Effluent Treatment Plant (CETP)

To assist industries at the Gujarat Eco textile park and to ensure effective management of waste water generated during the industrial processes an effective waste water system such as the Common Effluent Treatment Plant(CETP) has been developed to handle 60 MLD of waste water disposal expandable to 100 MLD.

The Common Effluent Treatment Plant is a part of the Environmental Infrastructure of GETP. This centralized facilities of the park, shall be meeting all statutory norms laid by Gujarat Pollution Control Board. It is state of art technology based on Sequential Batch Reactor System. It is environmentally sustainable and cost viable system for the collection, treatment and ultimate discharge of effluent from the wastewater generating units.

The Centre of Excellence will have world class infrastructural facilities like Exhibition and Seminar Halls , Meeting and Conference rooms , Physical and Chemical Labs , CAD Labs , Design Studios, Knowledge and Resource centre , Banks , Canteens and Restaurants , Fuel stations etc.

The Centre of Excellence is aimed at providing all necessary support to industries in India and around Surat, apart from those existing in Gujarat Eco-Textile Park in the areas of —

  • Man power training at all levels

  • Product Development

  • Product promotion

  • Testing and technical services

  • R&D in Textiles

  • Facilitation for various other needs by linking with service providers

  • Entrepreneurship development

  • Product identification and investment guidance

  • Formation of Knowledge centre and information dissemination

  • Creating awareness in various fields by organizing lectures, seminars and workshops.

A modern training centre

Skilled manpower is and would be the most crucial requirement of industries in India. The conventional method of "on-job" training by industry results in low productivity and poor quality. Therefore the need for training to match the productivity of international standard.

A joint venture of GETP and Ministry of Human Resource Development.

  • To provide continuous Manpower Training on need basis

  • To maintain pace with the fast changing requirements of Garments & Textile Industry like apparel, weaving, processing and embroidery by making use of latest technology, modern equipment and facilities

Key concerns that adversely affect productivity and quality

  • Lack of quality skills

  • Outdated syllabus

  • Lack of modern equipment & facilities

  • Inadequate number of training institutes

  • Lack of innovation in teaching methodology

  • Inability to scale up

To bridge the skills gap for productivity and quality

  • Technology enabled content, training methodology and blended training

  • Training methodology through multimedia

  • Standardization of content

  • Increase in number of people that can be trained at a time

  • Candidates can learn at their own speed

  • Shortage of trainers can be suitably addressed

  • Flexibility and improved learning experience for the trainees


  • Trained Manpower

  • Appropriate job oriented skills development

  • High level of productivity in terms of QQT (Quality, Quantity, Time)

  • Multi skilled operators

  • Accuracy over speed

  • To bring about a positive attitude amongst workers towards the fast training needs

  • To help maintain a healthy and harmonious spirit at workplace

The incineration is a widely used and internationally proven treatment technology for the disposal of toxic organic hazardous wastes like Tarry residue, Distillation residue, Off specification pharmaceutical products, Agrochemical Waste, Used / waste oils and Oily residues.

An Incinerator plant with a waste heat recovery system is being set up at the Gujarat Eco Textile Park. The Incinerator would have a capacity to burn 8500 to 9000 TPA of wastes. Incinerator System with a capacity of 6 million kcal/hour is being set up for this. The plant will be equipped with pretreatment facility and automated control system. Design and operation of the plant will be as per the guidelines of Central Pollution Control Board.

Captive Power Plant (CPO)

The Gujarat Eco textile park has planned a captive power plant for power generation based on natural gas. 4 Generators of 3 MW capacity each are being installed to meet the power demand in the park, which is estimated at 15.81 MW, including waste heat recovery boilers.
