Chapter 01 Introduction
Chapter 01 Introduction ============================= 1.1 Background Management of Biomedical waste has emerged as an issue of major concern not only to hospitals and nursing home but also to the civic authorities in urban centres. Bio-medical wastes generated from health care units depend upon a number of factors such as waste management methods, type of health care units, occupancy of healthcare units, specialization of healthcare units, ratio of reusable items in use, availability of infrastructure and resources etc. Government of India has published The Bio-Medical Waste (Management and Handling) Rules, 1998 on 20 th July, 1998 under the powers conferred by Sections 6, 8 and 25 of the Environment (Protection) Act, 1986. Hospital Waste Management is a part of hospital hygiene and maintenance activities. This involves management of range of activities, which are mainly engineering functions, such as collection, transportation, operation or treatment of processing systems, and disposal of wastes. The Centralized system of waste management is the best method in terms of cost reduction and minimizes legal and ethical hassles of health care staff & authority. Through centralized system, the hospital would feel less burden of waste management and might devote more time on development of quality patient care. Common bio-medical waste treatment facility (CBWTF) set up where bio-medical waste, generated from a number of healthcare facilities, is imparted necessary treatment to reduce all adverse effect that such waste may pose. Installation of individual treatment facilities by small healthcare establishments requires comparatively high capital investment. In addition, it requires separate manpower and infrastructure development for the proper operations and maintenance of treatment systems. The concept of centralized facilities emerged as a necessity since having individual treatment technologies was very difficult even for very large setups. Setting up and running treatment technologies requires space, huge investment, high operation and maintenance charges, technically qualified staff, waste to the maximum capacity of the machine to bring down the per kg treatment cost & monitoring pressure of government reduces etc. In comparison, if the waste from a number of healthcare establishments is brought at a centralized facility, all the above problems get scaled down The concept of CBWTF not only addresses these problems but also prevents scattering of treatment equipment in the city. Moreover, monitoring these facilities is much easier and one can assure that best and cleanest technologies with adequate pollution control devices are installed. In last few years various centralized facilities have come up all around the country. Sources of Biomedical wastes can be divided into major and minor sources, as given in Table 1.1 below. Table 1.1 Major and Minor Sources of Biomedical Waste Major Sources Minor Sources Hospitals, Nursing homes, dispensaries, Physicians, dentist clinics, blood banks etc. Pathological Labs., primary health centers, medical colleges and research centers etc. 1.2 The Proposal Passco Environmental Solutions Pvt. Ltd. (PESPL) proposes to setup a Common Bio-medical Treatment Facility at: Gut no 458/460/461, Village Moshi, Tehsil Haveli, District Pune, Maharashtra. Site location is given in Figure 1.1, Figure 1.2 and Figure 1.3. PESPL is running a BMW treatment facility for PCMC area at Yashwantrao Chavan Memorial (YCM) Chapter 01 Introduction Page 1 of 5
Hospital, Sant Tukaram Nagar, Pimpri, Pune. The site is ISO 9001-2008 and ISO 14001-2004 certified. PESPL is recipient of Environmental Excellence - Vasundhara Award instituted by Environment Department, Govt. of Maharashtra. The extant YCM Hospital facility is proposed to be decommissioned and replaced by a new, larger facility at the proposed site at Moshi. Location details of the site are given in Figure 1.1, Figure 1.2 and Figure 1.3. Figure 1.1 Key Location of the Site 1.3 Need for the Project Biomedical waste generation from the upcoming hospitals and other sites of generation is increasing due to increase in number of healthcare and research facilities, increase in healthcare occupancy and patient turnovers and increase in geographical extent of the city bringing more and more generators in the collection catchment. An increase of biomedical waste upto 10-15% year-on-year has been observed in the presently operating facility at the YCM Hospital. The common MBWTF facilities being operated in the city are almost at their design capacity leaving no room for management of operational contingency. In addition, newer standards of treatment and disposal are necessitating replacement of plants operating older hardware with latest state-of-art equipment. 1.4 Scope of the Project The project will have following scope: (a) Collection and transportation of pre-segregated biomedical wastes from member units (b) Treatment and disposal of the biomedical waste in a centralized facility proposed inside the waste treatment yard of the PCMC Chapter 01 Introduction Page 2 of 5

Chapter 02 Technical Details of the Common BMW Treatment Facility ============================= 2.1 Components of the Proposed Common BMWTF Key components of the proposed common BMWTF and capacities thereof are given in Table 2.1 below. Table 2.1 Key Components of the Proposed Common BMWTF and their Capacities Equipment Capacity Number Incinerator 150 Kg/hr 1 Autoclave 50 kg/hr 2 Shredder 100 Kg/hr 1 ETP 10 m3/day 1 D.G. Set ( With Acoustic Enclosure) 100 KVA 1 Utilities and amenities Chemical treatment facility and Sharp Pit Container Washing facility Vehicle Disinfection Area Wash room Material handling and Transportation equipments Store Rooms Gate and Security Room Workers amenities area Capacity of the proposed BMWTF is calculated considering 18 hours operation - 985.5 (150 kg x 18 hours x 365 days = 9.85 lac) MT per year for incineration & 657 MT per year for Autoclaving (50 kg x 2 x 18 hours x 365 days = 657 MT). Corresponding chemical treatment capacity as required from time to time. 2.2.1 Incinerator a. Incineration Process Incineration is a high temperature thermal process employing combustion of the waste under controlled condition for converting it into inert material and gases. Incinerators will be oil fired. Incinerators have primary and secondary combustion chambers to ensure optimal combustion. b. In the incinerator, solid phase combustion takes place in the primary chamber whereas the secondary chamber is for gas phase combustion. These are referred to as excess air incinerators because excess air is present in both the chambers. c. Thus the waste will be incinerated in two stages i.e. the primary chamber and the secondary combustion chamber which are positioned adjacent to each other. The flue gases then pass through the high pressure drop Venturi Scrubber, droplet separator and are let out to atmosphere via ID fan and chimney. The Primary Combustion Chamber operates under near pyrolytic condition wherein the wastes are decomposed & all volatiles are released. The substrate remaining gets converted into sterile ash. The volatiles released from the Primary Combustion Chamber are then completely burnt in the Secondary Combustion Chamber under high temperature and excess air.

3.3 Utility Requirement 3.3.1 Water Raw water to the tune of 5 kld will be required during construction phase for construction, concrete curing and dust suppression activities. Procured mineral water will be used for human consumption. About 25 kld raw water will be used during operation of CBWTF, out of which 10 kld will be recycle water and 15 kld will be fresh water. Water will be supplied by PCMC. Existing bores can alternatively be used for the small quantity make up. Water balance of the facility is given in Table 3.2. Table 3.2 Water Balance of the BMWTF Sr. Category Water Consumption (kld) Waste water generation (kld) 1 Domestic 2 1.8 2 Horticulture/Greenbelt 3 0 3 Process 26 0 Sub total 31 Grand total 31 1.8 Recycle 10 Fresh water 21 The unit will discharge only domestic effluent. The closed loop system for process water will ensures zero discharge of effluent. 3.3.1.a Water Recycling in Process The water discharged from the process of wet scrubbing of flue gas generated by incinerator will be collected in the seal pit below ground level. A screen chamber will be provided at the inlet line of the covered seal pit to avoid entry of bigger size particles. A reactor cum settling tank in MS fabrication, protected with Coal Tar Epoxy paint with attached mixer will be installed above ground. This water from the seal pit will be pumped to the reactor cum settling tank. The mixing of chemicals will be done manually. The desired quantities of chemicals will be dosed in the reaction cum settling tank. After flocculation and allowing for settling, the sludge from the reactor will be removed in the sludge filtering & drying mechanism. The effluent from the drying mechanism will be allowed to flow back to the seal pit which is below the ground level. The settled discharge which is at an elevated temperature will be transferred to a separate tank for makeup and cooling by adding fresh water. The temperature stabilized water which is normally alkaline in nature with very low suspended solids is suitable for flue gas scrubber of the incinerator. This process of post treatment system will ensure Zero Discharge. The post treated water which is suitable only for scrubbing of flue gases will be used exclusively for scrubbing and only domestic effluent will be discharged in to the Municipal Corporation drainage system with a dedicated drainage line ensuring no mixing of effluents. 3.3.1.b Sludge Dewatering The system will be designed to be modular. Dewatering cycle will consist of filling the bags with sludge for initial dewatering. Once the bag is full, it is removed, sealed and stored in open air for further dehydration reducing the weight and volume of the sludge cake. The special water repellent material of the bag will prevent rainwater from entering the bag and allowing dehydration by evaporation. One bag can generally dewater sludge up to 20 cum/day. 3.3.2 Power Power demand for construction phase is estimated at 15kVA. Three phase power is available at the site. During operation phase about 100 kva power will be needed. Power will be supplied by MSEDCL. Chapter 03 Operational Details of the Common BMW Treatment Facility Page 4 of 5
A DG of 100 KVA capacity is proposed as stand by power source. 3.3.3 Fuel HSD will be used as a fuel in the CBWTF. Fuel requirement for this plant will be about 180 MT/annum.
