Abstract: A treating system comprising a horizontal zigzag flow or vertical zigzag flow treating tank having a plurality of chambers constituted by horizontally or vertically dividing the inside of the tank by partitions and connected to one another in a horizontal or vertical zigzag fashion and having filter media installed in each chamber in a standing or lying position, or a treating system having independent chambers connected with one another where treating substances flow in an alternate fashion of downward and upward flows and is discharged from the last chamber and having filter media installed in each chamber in a standing position, said filter medium comprising a core element and a number of thin tapes of synthetic resin extending radially around the core element.The treating efficiency of the system may be increased by connecting an automatic gas-lift stirring device which performs stirring of the contents of the treating tank using methane gas generating in the treating tank.

Abstract: A method of transferring material from the bottom of a body of water provides a first tank submerged at a predetermined depth above the bottom. A material source is provided at the bottom subject to ambient water pressure, and is fluidly connected with the first tank. Material is transferred from the material source to the first tank by reducing the pressure in the first tank below the ambient water pressure at the predetermined depth. The ambient water pressure at the bottom thus forces the material into the first tank. Material is transferred from the first tank to a second tank under the force of compressed air until the first tank is substantially empty of material and full of compressed air. The first tank is connected to a third tank and an air compressor, the material transfer from the first tank to the second tank taking place by the compressor transferring compressed air to the first tank from the third tank.

Abstract: A method of transferring fluent material transfers the material from a first pressure tank to a fluent material transfer destination by supplying compressed gas to the first tank through a compressor. The compressed gas is retained in the first tank for reuse. Additional fluent material is drawn into a second pressure tank and is transferred therefrom to the fluent material transfer destination by supplying the compressed gas from the first pressure tank to the second pressure tank through the compressor. The compressed gas is further retained in the second pressure tank transferring fluent material from the first pressure tank. As the compressed gas is emptied from each tank to the other tank, additional fluent material is drawn into that tank. The cycle can be repeated on a continuous basis to transfer large quantities of fluent material.

Abstract: A method of transferring water provides potential energy with the air pressure of compressed air and uses compressed air used for transfer repeatedly and continuously. The compressed air is retained at the place where the water is transferred from. The compressed air retained is drawn and compressed by a compressor for another transfer operation, and the water is transferred continuously by an alternate replacement between the compressed air and the water. The water can be brought into a place by water pressure where the compressed air acts on the water.

Abstract: A method of transferring objects provides potential energy with the air pressure of compressed air and uses compressed air for transfer repeatedly and continuously. The compressed air is retained at the place where the objects are transferred from. The compressed air retained is drawn and compressed by a compressor for another transfer operation, and the objects are transferred continuously by an alternate replacement between the compressed air and the objects. The objects can be brought into a place by water pressure where the compressed air acts on the objects.
