... for the desalination of the seawater is proposed. The plant is composed of reverse osmosis and multistage flash in series. Electrical and thermal energy are supplied by a cogeneration group for the production of electrical and thermal energy connected to the public net. From a first analysis, the... simplifications and cost reduction for the fresh water, compared to the equivalent systems in parallel. Desalination 153 (2002) 167–171 Energy saving with MSF–RO series desalination plants Ennio Cardona*, Salvatore Culotta, Antonio Piacentino DEAF – Department of Energy and Applied Physics ...

... power factor surcharges on your electricity bills. For this purpose, this work presents an electronic circuit for the measurement of electrical energy. The design is based on a sample and hold method, which generates two DC signals. The first signal is proportional to the peak value of the line... circuitry. Results are presented to show the effect of a changing power factor on the power available at a constant current and the annual cost savings that can be made.

... same feed flow rate. Although the hydraulic dissipated power was significantly increased (about 6 times), the decrease of more than 25% in specific energy consumption was obtained by the use of the static mixer. Moreover, the presence of the static mixer in the membrane tube provided the similar... similar permeate flux values at about 5 times lower cross-flow velocity, thus reducing the energy consumption for more than 80%. Additional energy saving was achieved using the Kenics static mixer with the aspect ratio (ratio of element length to mixer diameter) greater than 1, especially at th ...
