Analysis Productive Uses of Water in the Arid Areas of the Rural Northeast in Brazil: Ensuring Diffusion of Renewable Energy and Sustainable Development This study provides an initial cost-benefit assessment of productive, efficient uses of water by small farmers in the semi-arid regions of the Brazilian Northeast, unveiling additional opportunities for the use of renewable, decentralized sources of energy for increasing income generation among the small rural producers (1). Results indicate that pay back occurs within a range of 1 to 4 years, depending on sources of energy and mainly on the aggregated value of the product. Read more

Technology Photosynthesis System for Managing Water in Irrigated Agriculture The Projeto Fotossíntese (Photosynthesis Project) promotes the rational use of water in the irrigation of intensive arable farming, and the supply of water to homes and apartment buildings. Its objective is to maximize agricultural production for each drop of water used. The method consists of evaluating the solar irradiation which gives rise to photosynthesis and generates the necessary energy for the circulation of water and nutrients inside the plants, according to the moisture conditions of the soil around the roots of the crops. The result is that water is applied in the optimum amount, and at the ideal moment for the crop being irrigated, resulting in environmental conservation. Premium Content

Case Studies Treatment of high-strength winery wastewater Wine and grape wastewaters are more difficult to treat than other wastewaters from food processing plants. Wineries generate industrial effluents that due to their composition and high organic strength, seasonal variability, acidity and unpleasant odors represent both environmental and esthetic problems in wine producing countries. Thus, there is a strong need for efficient, cost-effective, compact, wastewater treatment systems with minimum operation and maintenance requirements. In response to these demands Water Purification Technologies Inc., a Canadian company, has developed a series of advanced wastewater treatment units with the generic name of Active Biological Contactor (ABC). This paper describes the performance of one of those units, tested in a well-known winery located in St. Catharines (Niagara Peninsula, Ontario). Premium Content Developments in the Use of Bio-Solids in NW Spain Presently, the number of waste water treatment plants (WWTP) in the region is going to increase due to the new European environmental policies. Primacy is being given to valuing and reusing all the resulting biosolids for agronomic purposes over eliminating or destructing them. The use of biosolids reduce fertilization costs for farmers, such important sector for the Galician economy. Agroamb is a young Spanish company, located in the Northwest of Spain (Galicia), specialized in the soil application of biosolids, an emergent sector in this region. Agroamb has three projects of investigation in collaboration with the universities of Santiago de Compostela and Vigo, evaluating the use of different biosólidos (sewage sludge, ashes, flours, manures, etc) for elaborating organic fertilizer and its economic and environmental viability. Read more New Environmentally Friendly Enzyme Based Solution for Wastewater Remediation The effluent generated by livestock at agricultural operations all over both North and South America has a significant environmental footprint that flows far downstream from its source. One Hog farm in particular has been using a breakthrough technology referred to as UltraZyme to enhance the biological activity within its waste lagoons in order to discharge a much less toxic waste stream into the environment. UltraZyme has been in use for over a year now at a hog farm owned by Blue Ribbon, near Panama City, Panama, and its results have been closely monitored through lab tests, visual verification and testimonials, proving its great success.
