Management of Hazardous waste There will be generation of Dilute Hydro Bromide (30%), Dilute Hydrochloric Acid (30%) & Dilute Ammonia (17.5%) as a by-product which will be handled as per Hazardous and Other Wastes (Management and Transboundary Movement) Rules 2016, the details of which are summarized in the following table.

Separate quantity of fuel consumption in MT/day for Biofuel/Agro waste& Coal. Unit proposes to use Biofuel/Agrowaste and/or Coal for Steam Boiler (5.0 TPH) and Diesel for DG Set (20 KVA). Details of the fuel requirement are given below; Sr. Maximum Average Fuel Calorific Value Utility No. Requirement Requirement Bio Fuel/ Steam 1. 3,850 Kcal/Kg 5.4 TPD Agricultural waste Boiler 5 TPD 2. Coal 4,500 Kcal/Kg (5.0 TPH) 4.6TPD DG Set 3. Diesel 9,500 Kcal/Lit 1.25 Lit/Hr 1.25 Lit/Hr (20 KVA) 3. Justification for disposal of spent catalyst into TSDF site. Requirement of Raney Nickel catalyst will be 3.96 Ton/Annum for the manufacturing of product Venlafexin HCl and the generation of spent catalyst will be 4.5 Ton/Annum. This may contain other impurities and will not be feasible to recover Nickel from the same. Hence, spent catalyst Raney Nickel has been proposed to dispose by landfilling at TSDF. However, we will explore the possibilities to recover the precious metal by sending it to re-processors if it is techno-economically feasible. 409 – Saffron Complex, Fatehgunj, Vadodara – 390002 (Gujarat) INDIA Phone : +91-265-3916549, Fax : +91-265-3916548 Email: [email protected], URL : www.choruspharmachem.com 4. Treatability study & adequacy report for High Ammonical waste bearing stream. The industrial effluent generation from proposed project will be 40.9 KLD. Earlier with the EIA report, we submitted proposal to treat industrial effluent in ETP having MBBR technology comprising of primary, secondary and tertiary treatment units. Now, we propose to adopt ETP scheme based on hydro-dynamic cavitation treatment which effectively removes Ammonical Nitrogen from effluent, hence segregation of high ammonical waste bearing stream will not be required. Treatability study carried out for hydro-dynamic cavitation by Nandesari Industries Association (NIA) is enclosed in Annexure B. Treatability results show that proposed ETP having hydro-dynamic cavitation system will be adequate to treat industrial effluent in achieving norms prescribed by the CETP of NIA for further treatment and final disposal. Stream-wise and stage-wise characteristic of effluent are given in Table 1 and Table 2 respectively. The details of ETP units are given in Table 3. Treatment Scheme: The wastewater from the plant will be collected in the collection cum neutralization tank. The wastewater will be equalized over organic matter and flow. The pH of the wastewater will be raised to 10.5 by addition of hydrated lime and filtered. Then the filtered wastewater will be pumped through a ventury into hydrodynamic cavitation tank. At the suction side, chlorine will be injected to achieve hydrodynamic cavitation. This is a batch process and the system will be kept under recirculation till the COD reaches to desired limit. pH of the effluent will be checked continuously and when it will drop about 8, fresh lime will be added into the effluent. The process will be continued until the effluent gets colorless and COD drops below the inlet norms of CETP of NIA. The effluent will again be filtered in the filter press and then it will be sent to CETP through tankers. The following checks and precautions will be taken for hydrodynamic cavitation process. 409 – Saffron Complex, Fatehgunj, Vadodara – 390002 (Gujarat) INDIA Phone : +91-265-3916549, Fax : +91-265-3916548 Email: [email protected], URL : www.choruspharmachem.com 1. The hydrodynamic cavitation tank will be provided with 6 m liquid depth and will be kept half empty. 2. Barometric header of minimum 7 m for addition of chlorine will be provided. 3. pH of the effluent will be checked continuously. 4. Venturi with pipe flocculator will be provided for the best results as chlorine will be mixed completely. 5. Sparger will also be provided for through mixing in order to achieve better results. 6. Alkaline pH will be maintained to control emission of un-reacted Cl2 during hydrodynamic cavitation process. However, any un-reacted Cl2 gas generated will be sent to caustic scrubber provided in the process plant through vent on hydrodynamic cavitation reactor. The schematic diagram of effluent treatment scheme and set up of hydrodynamic cavitation system are given in the Figure 1&Figure2 respectively.
