REDUCTION IN THE CONSUMPTION OF EFFLUENT GENERATED IN NILE TILAPIA SLAUGHTERHOUSE THROUGH THE CONCEPTS IMPLANTATION OF CLEANER PRODUCTION (CP)

the nourishing industry is a segment that makes use of high water consumption due to necessity of the hygienic cleaning of the establishments and the maintenance of the good quality of the food. It enters the nourishing industries with bigger water consumption we have the fishery industry which generates effluent around 5.4 m(3). t(-1) of processed fish. This work had as objective the reduction in the water consumption of the processing of Nile tilapia through the implantation of P+L techniques, for had been in such a way carried through hydraulical alterations in the filleting tables aiming at the minimum possible water consumption for two methods of filleting, eviscerated and not eviscerated, as well as the comment of the alterations in the generated quality of the effluent one. In the present study, the reduction in the water consumption in the filleting process corresponded 98.16% for method EV considering an average time of processing of 3 hours for 32.99 kg of fish, and for method NEV the reduction was of 97.97% with average time of processing of 2.1 hours for 34.96 kg of fish, thus demonstrating that the P+L techniques are efficient for the reduction of the water consumption.34228929

A mídia (TV, rádio etc.) foi o meio de comunicação mais importante como fonte de informação sobre a doença para a população. No entanto, observou-se uma lacuna entre o conhecimento e a prática de atitudes voltadas para evitar a proliferação do mosquito do dengue.
