2.12 PROJECT IMPLEMENTATION AND PRODUCTION SCHEDULE
30 MW cogeneration plant will be commissioned by before the next 2004 crushing season. After completion of l(with installation of additional MW double extraction cum condensing TG set and associated auxiliaries / electrical), the total installed capacity will be 30MW power for 160 days of season operations on own bagasse and 25.6 MW power for minimum 140 days of off season operations, on saved bagasse / procured bagasse / equivalent bio-mass.
2.13 POWER REQUIREMENT
Total of 30 MW power is required for the captive use in sugar plant & power plant and for meting the power requirement
The industry has proposed to install 30 MW steam turbo-generaior. The power required to meet the emergency requirement of power during power failure. Two diesei gen-sets each of 250 KVA are installed.
2.14 WASTE WATER GENERATION AND ITS SOURCE
The waste water generated in sugar factory is non toxic and non hazardous. Further the sugar processing does not involve any process water discharge. The waste water generated is mainly due to washing of floor and equipments in
addition to boiler and cooling water purge. The waste water generated can therefore by substantially reduced by good house keeping. The details of source
and quantity of wastewater from sugar factory is enumerated below.
2.15 Spillage, Leakage & Floor Washings
In a sugar factory wastewater (effluent) is generated mainly due to washings, leakage and spillage of syrup and molasses in different sections of the manufacturing plant. Leakages occur at pipe joints and pump glands. Spillage and splashing occur at different equipments. The periodical washing of floor contributes significant pollution load to the waste water. Clearing of equipments such as evaporators, pans, juice heaters etc. also produces waste water. Though, these wastes are small in quantity but contains BOD and low pH. Good housekeeping, effective maintenance and efficient piant operation can considerably the generation of this waste water. Spillage and washings can be collected in small sumps constructed at convenient locations and these can be recycled to the process, if planned well the generation of such waste water can be totally avoided. The effluent from mill plant contains fibres, grease and oil.
