IETP, CETP & ZLD PROJECTS

Zero Liquid Discharge (ZLD) is the toughest regulation that can be implemented in polluting industries, wherein, not a drop of wastewater can be discharged and complete recycling of the Wastewater is done. TWIC has been a pioneer in the implementation of Zero Liquid Discharge Systems as a Project developer and Consultant for over 14 Common Effluent Treatment Plants (CETPs) in the Textile and Tannery sector operating in Tamil Nadu.

 Of this, 10 Textile CETPs have been developed by TWIC with capacities ranging from 3 MLD to 11 MLD with a combined capacity of 54.4 MLD and 4 Tannery CETPs with a combined capacity of 10.2 MLD:

1. TWIC has developed and established 9 Textile dyeing CETPs with combined capacity of 53 MLD in Tiruppur based on ZLD and have played a key role in revival of the industry in Tiruppur after prolonged closure due to the High Court Orders.
2. TWIC has implemented similar CETP projects in the Ambur, Vanniyambadi Tannery belt (3 CETPs) in Tamilnadu and has also worked in Pallavaram-Chennai, which is another Tannery CETP.
3. TWIC is also an Independent O&M operator for 7 CETPs for a period of 15 Years.

• TWIC has worked with Ministries / Government Departments in Tamilnadu, Haryana, Telangana, Uttar Pradesh and Rajasthan for implementation of CETPs.

1. Panipat Textile Cluster – Project Management Consultant (PMC) for Diagnostic study, Preparation of feasibility report and DPR for establishment of ZLD CETP
2. Telangana, Medak District – PMC for Preparation of feasibility report and DPR for establishment of CETP at Indrakaran Textile Park.
3. Rajasthan, Bithuja – PMA for preparation DPR and implementation supervision for establishment of Common caustic recovery pilot plant
4. SIPCOT, Perundurai-  Project Management Agency (PMA) for up-gradation and Operation and Maintenance agency of IETP (Textile wastewater)
5. TWIC also worked with a large Pulp & Paper mill in South India for implementing and operating a pilot plant to study the techno-economic feasibility for implementing a ZLD system for mill effluent.
6. TWIC has also implemented technologies such as the ‘Brine Reuse Technology’ for the Textile industry & Separation of Sodium Sulphate for Pulp and Paper & Crystallisation of Glauber’s salt etc., for further management of Reverse Osmosis Rejects.

• All these projects contain highly complex and state of the art technologies and systems such as:
• Total Biological Oxidation (TBO)
• Tertiary system based on Quartz, Decolourant Resin and Softener resin filters, Salt separation resins.
• Membrane Bio-reactors (MBR)
• Membrane Technologies such as R.O., Nano and Ultra Filtration.
• Mechanical Vapour Recompression type and Multiple Effect type Evaporators.

CETP PROJECTS UNDER NAMAMI GANGA PROGRAMME

TWIC has been engaged by the National Mission for Clean Ganga (NMCG) under the Ministry of Jal Sakthi, GoI as a consultant, for establishment of 20 MLD CETP at Jajmau Tannery cluster and 5 ZLD CETPs for Mathura, Farrukhabad, Rooma, Bhadohi and Pilkhuwa textile clusters in UP state, India for addressing the pollution caused by the industries on Ganga & Yamuna Rivers. The Detailed Project Reports (DPRs) for the above projects were already submitted and construction of 20 MLD tannery CETP works is under progress.

TWIC has a rich history of delivering suitable solutions for water, wastewater and reuse solutions. We can provide experience and services in all aspects of Membrane-based desalination technology ranging from 0.5 MLD to 150 MLD. TWIC has extensive experience in developing Sea Water Reverse Osmosis (SWRO/BWRO) plants for Open Sea Source, Back Waters and Creek. Carrying out various survey activities such as oceanographic survey, Onshore and offshore Geotechnical Investigation, Topo Graphic Survey, Preliminary EIA, Feasibility Studies, Candidate Site Evaluation, Process Design (Intake, Outfall, Pre-treatment, Membrane Filtration and Post Treatment) and Engineering, Contract and Procurement, Bid Process Management and Transaction Advisory, Project Management Consultancy (Inclusive of Engineering Documents – Review, Construction, Erection and Commissioning Supervision, Third Party verification). 

Our major achievements are as follows

Water is a prime source for all the living creatures in this world for its existence. It exists in the form of Surface Water as well as Groundwater. The forms of surface water are lakes, ponds, rivers etc., which can be quantified easily; it is prone to pollution and vulnerable also. In most cases surface water gets polluted by human intervention in the way of disposing of human waste, sewage into the lakes/ponds and rivers and dumping of solid waste in water bodies. On the other hand, the growth of industries had also played a major role in polluting water bodies by the way of disposing the industrial effluents into the water body. One such common problem in metro cities of India is pollution of rivers by disposing of domestic sewage and industrial effluents into it. Hence river pollution abatement works and restoration and rejuvenation of water bodies are essentially needed to prevent deterioration of water bodies and its ecology. TWIC is actively providing consultancy services by approaching Hydrological, Environmental cum Ecological Interventions & Engineering Interventions, Selection of appropriate technology solutions viz.(i)Intercepting and collecting sewage outfalls to treat in the de-centralized treatment plants. (ii) Constructed wetlands to treat the raw sewage naturally through ecological engineering techniques, (iii) Providing Riparian Buffer zone of native vegetation for protection of the river banks on both sides and improving its ecology, (iv) Construction of Under Ground Sewage System (UGSS) and Centralized Sewage Treatment Plants etc., design development, preparation of DPR, Transaction Advisory Services and Project Management services for implementation.  TWIC experiences in this field are as follows:

1. Feasibility study for the selected River Stretches in Vaigai, Bhavani & Cauvery Rivers
2. Preparation of DPR for the selected River Stretches in Tamarabarani, Vashista, Sarabanga, Cooum, Gadilam, Pennaiyar, Palar, Vaippar, and Aliyar Rivers
3. Preparation of DPR for Restoration and Rejuvenation of 60 Water Bodies in Greater Chennai Corporation Area and Mudasarlova Lake catchment in Greater Vizag Municipal Corporation.
4. Audit of the technology and proof checking of proposals submitted by various departments towards restoration and maintenance of Ooty lake
5. Providing Project Management Agency Services for Restoration of Zamin Pallavaram Periya Eri (Lake) and Keelkattalai Eri (Lake) in Pallavaram Municipality in Tamilnadu State.
