  • Patent number: 8778176
    Abstract: A potable water producing system for disposition at a body of salt water and a method of producing potable water is provided. The system includes a wave energy conversion system (AWECS) and a portable filtration-anchor system. The AWECS is in the form of a floating articulated barge housing a desalination system including a reverse osmosis membrane. The filtration-anchor system is submerged in the body of salt water and includes a sand filter to filter the adjacent salt water and to provide the filtered salt water to the desalination system on the articulated barge. The action of the waves on the articulated barge provides energy to pump the filtered salt water from the sand filter to the reverse osmosis member to produce potable water. Moreover, the action of the waves on the articulated barge effects the shaking of the reverse osmosis filter, thereby rendering it self-cleaning.

  • Patent number: 8641892
    Abstract: Debris adhering to the outer surface of a barrel-type fish screen is cleared by air bursts from a series of perforated air pipes positioned inside the outer foraminous shell of the screen, the perforations being holes with axes at an acute angle to the screen radius for efficient use of the air. Separately, the conical water collection manifold mounted inside the shell is open at its narrow end, with a valve mounted to that open end to control the opening. The opening prevents reduced water inflow at that end of the manifold, and the valve adjusts the access of the surrounding water to the opening, thereby allowing the manifold to be tuned to more closely approach a uniform distribution of axial water flow along the length of the collection manifold for different ambient conditions.

  • Publication number: 20040208704
    Abstract: A method is disclosed for constructing a manhole structure in which a manhole and a pipe are joined together by using a waterproof flexible joint. The joint includes a rigid cylindrical portion and a cylindrical flexible portion that has a covering portion to be fixed around an outer periphery of said pipe, a fixing portion fixed to an outer periphery of said rigid cylindrical portion and to be fixed to the manhole and a connecting portion connecting the covering portion to the fixing portion and made of an elastic material being capable of absorbing a displacement between the manhole and the pipe. The waterproof flexible joint is located around the outer periphery of the pipe, and the covering portion is fixed around the outer periphery of the pipe. Then, a filler for the manhole is poured around an outer periphery of the fixing portion.
