25. Conservação da água na indústria do papelão ondulado : estudo de caso
In this work, the water conservation is proposed as a way to improve the water use and the wastewater generation in the paperboard package industry. Therefore, the rational use and reuse of water are the conservation tools adopted. These tools were applied in a paperboard package plant, located in the Farroupilha city (Rio Grande do Sul, Brazil), and had the

27. Water pricing optimization for demand management in long-term scenarios / Otimização da cobrança pelo uso da água para a gestão da demanda hídrica em cenários de longo prazo
Water pricing is a water resources management tool according to brazilian law 9433/97 and it serves the purpose of giving incentive to rational use of water, among others. However, studies and simulations treat pricing as a revenue generator mechanism only. This dissertation aims to propose water unit prices based on demand reduction needs in the Tietê-Jaca

32. Reúso e minimização do consumo de água em indústrias químicas utilizando a regeneração diferenciada de contaminantes
Currently there is a great demand for tools that allow the analysis of water nets in a practical and objective way. In the modern scenes the chemical, petrochemical, textile and of paper and cellulose industries consume great amounts of water and need to make it in more rational form, because that the water becomes a scarcer natural resource. The methodology

35. Sugar cane sensitivity (Saccharum spp.) to soil water excess / Sensibilidade da cana-de-açúcar (Saccharum spp.) ao excesso de água no solo
Almost all sugar cane produced in the State of Sao Paulo is grown under rainfed conditions and the exploration of new cultivated areas, were there is a need for drainage, becomes important. The design of agricultural drainage systems based only on practical experience of the designer has led to frequent failures. For the rational sizing, it is necessary to k
