A long-lived, lightweight, and quickly and precisely charged storage capacitor power supply capable of stably supplying electric power to a load. The power supply has a capacitor block consisting of capacitors connected in series, in parallel or in any combination of series and parallel. The power supply further includes a charging circuit for charging the block, a charging power supply connected with the block via the charging circuit, and a charge-limiting circuit. This charge-limiting circuit detects the voltage across the terminals of the block and limits charging of the block if the voltage reaches a given value. One embodiment of the invention further includes a charge-limiting circuit, a full charge-detecting circuit, and a residual electricity-detecting circuit connected in parallel with the block. The charge-limiting circuit senses that the voltage across the terminals of the block exceeds the given value and causes the charging current to bypass the block. The full charge-detecting circuit senses that the charge-limiting circuit is operated and determines that full charge is attained. The residual electricity-detecting circuit finds the residual electric power from the voltage across the terminals of the block. Another embodiment has a first and a second capacitor block. The voltage across the terminals of the first block is detected. The first block is charged from the second block until the detected voltage reaches a given voltage. The first block supplies electric power directly to the load.

A substrate processing apparatus has a two-fluid nozzle having an inner cylindrical member and an outer cylindrical member. Gas flows in the inner cylindrical member which is a gas passage and the processing liquid downwardly flows in a processing liquid passage constituted of the inner and outer cylindrical members. The gas and the processing liquid are mixed in a mixing area below the inner cylindrical member to generate fine droplets, and the droplets are ejected from an outlet of a lower end of the outer cylindrical member onto a substrate. Charge is induced on the processing liquid by generating an electric potential difference between a first electrode provided in the gas passage and a second electrode provided in the processing liquid passage, to generate charged droplets. In the nozzle, the first electrode is isolated from the processing liquid with a simple construction, and the droplets can be charged efficiently.

A system and process for enhancing total organic carbon (“TOC”) removal from raw, untreated water while maintaining optimum membrane filter performance. The present invention overcomes many of the disadvantages of prior art water filtration systems by controlling the pH level of the water, prior to the water being directed through said membrane filter, so that the particulate charge of the water aligns with the electromagnetic surface charge of membrane filter. Maintaining the particulate charge of the water within an optimum charge window for the particular membrane filter enhances the membrane filter's performance by decreasing the fouling rate of the membrane filter.
