| Este trabalho foi um levantamento dos efeitos da dejecao de dois sistemas de dessalinizacao por osmose inversa (RO) de agua de pocos, sobre o solo, localizados nas comunidades de Rajada e Uruas, no municipio de Petrolina-PE. Nessas comunidades estudadas, bem como em todas as comunidades do semi-arido brasileiro, os rejeitos da dessalinizacao sao despejados em sistemas de drenagem natural, sem nenhum tratamento, podendo causar danos ao solo e meio ambiente devido aos seus elevados teores de sais. |

| Abstract: The Programa Água Doce-PAD(in English: Fresh Water Program) promoted by the Brazilian Federal Government under the coordinationof the Environmental Ministry, seeks to promote sustainable use of groundwater resources and provide potable water for human consumption in areas withcriticalwater scarcity in the Brazilian Semiarid region, through the use of the Reverse Osmosis Technique. The Program is guided by the following principles: community empowerment, environmental sustainability and technicalcapacity building. The methodology that led the Program to becomea success case was conceived in 2003, through a participatory process with the contribution of public Brazilian institutions such as: Federal University of Campina Grande-UFCG (Social... |

| Desalination is characterized by rapidly evolving technologies. These technologies are divided mainly into thermal and membrane processes. Thermal processes, however, have numerous limitations, which include intensive use of energy and corrosion problems while membrane processes suffer from membrane fouling and high membrane cost and other problems. Liquid membrane (LMs), on the other hand, which have been discovered in 1968 by Li have no pores to be blocked and cannot be fouled like solid membranes. They also exhibit higher permeabilities and higher selectivities than solid membranes. However, their main problem is the method of containing the liquid between the two miscible but separated donor phase (DP) and receptor phase (RP). LM techniques include... |
