摘要： There is a method described of treating tailings which are composed of at least some water and clay particles. Within the tailings, at least some water molecules are weakly bond to the clay particles to form a gel like fluid from which water does not readily separate. An alternating current is applied to the tailings to change the electro-chemical properties of the tailings to reduce the weak bonding between the water and the clay particles so that water within the treated tailings is able to separate. Water within the treated tailings is then allowed to separate without further application of electricity. In some embodiments, the treated tailings are allowed to separate through evaporation. Liquid tailings may also be treated with alternating current by applying alternating current to the liquid tailings at a voltage gradient range of 1 to 5 V/cm for a total duration of 24 to 300 hours. The application of alternating current may further comprise applying alternating current at a frequency of 1 to 30 Hz.

摘要： An immersed membrane filtration system is operated in view of an electricity pricing programs in which the price of electricity varies over time. Examples of such programs include time of use pricing, critical peak pricing and critical peak rebate programs. Alternatively, the filtration system may be operated, for example as part of a smart grid, in view of requests or demands by an electrical utility for time limited reductions in energy use. During a high energy cost period of time, one or more membrane units are shut down. Preferably, aeration of the still operating membrane units is not increased. The flux of the still operating trains may be increased towards a pre-determined maximum permitted flux, or towards a maximum flux that is calculated in view of operational parameters such as water temperature or viscosity. Optionally, during a low energy cost period of time, one or more additional membrane units may be turned on. Optionally, the transfer of water from an equalization tank may also be controlled in view of the energy pricing program.
