Diagnóstico das piscinas de uso coletivo no município de São Carlos - SP / Diagnostic of collective use swimming pools in the city of São Carlos - SP

Santos, Denise Conceição de Gois 30 July 2004 (has links)
Este trabalho de pesquisa acadêmica, precipuamente, objetivou avaliar por amostragem, a qualidade sanitária das piscinas de uso coletivo da cidade de São Carlos, SP, com base nas legislações vigentes. O Código Nacional de Saúde, no artigo 44 dá realce ao planejamento, construção e uso das piscinas coletivas sujeitas ao controle das autoridades sanitárias competentes. O Código Sanitário do Estado de São Paulo, no decreto 12.342 de 27 de setembro de 1978, apresenta especificações para as águas de piscina. Para avaliação das instalações anexas foram estudados projetos, construção, operação de equipamentos, manutenção da área construída; foram feitas, também, vistorias das referidas instalações das piscinas propriamente ditas. Com base na legislação estadual e nos padrões da CETESB (Companhia de Tecnologia e Saneamento Ambiental), foram estudados regulamentos quanto a pessoal de apoio; e por meio de parâmetros físicos, químicos e bacteriológicos foi avaliada a qualidade da água de cada unidade amostral do universo de pesquisa deste trabalho porque, em conjunto, os anexos, o tanque de recreação e a água são responsáveis por problemas de saúde pública. Em São Carlos, das 28 piscinas de uso coletivo, que se enquadram nas regras do Decreto do Estado de São Paulo nº 12342 de 27 de setembro de 1978, por processo de amostragem estratificada foram selecionadas 18 piscinas, que perfazem 64,3% daquelas viáveis para o trabalho, pertencentes a nove localidades ou estabelecimentos. O espaço amostral buscou abranger piscinas de clubes, de instituições de ensino e de academias das classes sociais A, B e C; cobertas e descobertas; infantis e de adultos. / This research work evoluated the sanitary quality of collective use swimming pools in the city of São Carlos, SP. Acoordingly, the pools facilities were investigated in the following subjects: projects, construction, equipments operations, as well as the pools performance inspections themselves. Based on State Legislation and according to the CETESB (Companhia de Tecnologia e Saneamento Ambiental) patterns studies were performed concerning support personel, and the water quality of each stuied unit, in terms of: physical, chemical and bacteriological parameters. From the 28 colectif pools, 18 were selected for this work wich represent 64,3%, and this sampling space, covered club polls, schools and social academies for classes A, B and C, for children and adults.

Solar energy for domestic use

Van Zyl, GHC January 2000 (has links)
Thesis (MTech(Chemical engineering))--Cape Technikon, Cape Town, 2000 / The demand for pool heating has increased dramatically over the last few years. This is ascribed to the idea that a swimming pool is expensive and can only be used for four months of the year. Therefore, a need for a relatively inexpensive solar heating system, capable of heating pool water to comfortable temperatures for an extended period, does exist. The least expensive solar heating system for swimming pool heating on the market in South Africa is in the order of R 11000. This is a fixed system, usually mounted on the roof of a house. In order to ensure the safety of minors, a safety net or sail must be installed. This is an additional cost, which approximates R1500, yielding a total cost for safety and heating in the order of R 12500. Copper pipes packed in black material are utilised in these conventional heating systems, and it is the cost of this good heat conductor that makes these units expensive. In this study an alternative pool heating system constructed of PVC was investigated. The system is designed to be flexible, mobile, act as a safety mechanism and absorbs the maximum amount of solar energy available. Dark blue material as opposed to black PVC was selected for aesthetic reasons at the expense of maximum efficiency. The material strength was tested as well as the strength of adhesion. The influence of factors such as exposure to the sun and the effect of water containing chlorine and acid on the material were evaluated. Also, various means of channelling the water through the system for increased efficiency was investigated. A pilot model was constructed and its performance evaluated. It has been concluded that the alternative approach provides effective heating at a lower cost than current systems. Also, the durability of the design was found to be acceptable.
