This is a method of filtration of a liquid comprising steps of sequential filtration of said liquid through at least one deep bed medium producing at least one first filtrate followed by at least one membrane medium filtration producing at least one second filtrate, wherein said membrane medium is at least periodically within said deep bed media Many types of deep bed and membrane media can be used. The domain of using contact clarification (direct filtration) can be expanded towards greater solids concentration. Operation and backwash, is simplified, continuous filtration becomes possible. Water can be water from natural source water, process water, wastewater, aqueous or non-aqueous suspensions, emulsions, solutions. Treatment can include mechanical interception of suspended particles, chemical, physical chemical, electrochemical, and biological processes. In water and wastewater processing, control over suspended solids, BOD, COD, nitrogen and phosphorus compounds, bacteria and viruses, heavy metals, color, and other constituents can be dramatically improved as compared to conventional processes.

Method and apparatus for low frequency induction therapy for the treatment of urinary incontinence and overactive bladder
Current treatment options for Overactive Bladder and Urinary Incontinence include exercise and behavioral modifications, pharmacological therapies, surgical intervention, and neuromodulation. Although each of these treatments is used in the treatment of individuals with these conditions, each has severe limitations. Building on the limitations of existing therapies, and with the distillation of lessons learned from the field of pulsed electric stimulation, the present invention employs Low Frequency Induction Therapy for the delivery of an effective, cost efficient, noninvasive alternative to available treatment options. The device of the present application allows for consistent, user-friendly modulation of the pudendal nerve and the sacral plexus, via pulsed electromagnetic stimulation of the posterior tibial nerve, on an outpatient basis. The device has two primary components: a programmable Logic Controller (LC), which generates the required current, and a Conductive Wrap (CW), through which the current is channeled in generating the pulsed electromagnetic fields.
