摘要： Provided is a fluid processing apparatus using a crystallization promoting medium (CPM) as a fluid processing medium. The apparatus comprises one or more column bed units in parallel connection, wherein the column bed units may be connected in parallel with a bypass flow path having a check valve, and except the first column bed unit, each of the column bed units is provided with a check valve upstream thereof. Also provided is a method for improving the efficiency of a CPM-based fluid processing apparatus having only one column bed unit. The method comprises: replacing the column bed unit of the CPM-based fluid processing apparatus having only one fluid processing column bed unit with: (i) a plurality of secondary column bed units in parallel connection, wherein the secondary column bed units may be connected in parallel with a bypass flow path having a check valve; and except the first secondary column bed unit, each of the secondary column bed units is provided with a check valve upstream thereof; or (ii) one column bed unit and a bypass flow path that is connected in parallel with the column bed unit and has a check valve. Also provided is a proportional check valve that opens proportionally as the pressure increases.

摘要： In one embodiment a reverse osmosis permeate pump with shut off valve and reverse osmosis system employs bypassed feed water from the reverse osmosis membrane to drive a water wheel and gear set to reciprocate a piston back and forth between two chambers in the pump. Permeate from the membrane is introduced to the respective chambers by a pair of fluid inlets and discharged from the respective chambers through a pair of discharges to a storage tank. Flow through these respective inlets and discharges is a function of the direction in which the piston is moving and whether it is imparting a pressure or suction on a given chamber. A second piston is exposed to the pressure in the discharges from the chambers and the second piston moves between a position permitting incoming feed flow to the membrane, and a position blocking that flow upon increase in pressure in the fluid discharge from the chambers. In another embodiment, the reverse osmosis permeate pump is powered by an independent source of power. In both embodiments, the pump and shut off valve is on the permeate side of the membrane which permits a substantial reduction in pump size, and the permeate pumps and shut off valves of the invention permit substantially increased pressure drops across the membrane and increased system production capacities and rates.

摘要： Regeneration of water treatment media is disclosed which includes a water treatment unit having one or more media therein, and which upon initiation of flow of the water, imparts turbulence and abrasion to the treatment medium to automatically cleanse the medium of light solid contaminants, as well as contaminant coatings on the media. This greatly improves the operation of the media and extends its life. In addition, the water treatment unit disclosed may simply be rotated through any one of a number of positions between service, backwash, flush, off, and/or bypass operational modes for further regeneration of the treatment media.

摘要： A fluid magnetic treatment unit and treatment method are disclosed. Fluid flows through at least one annular magnet with direction of flow always perpendicular to the line of magnetic force generated by the annular magnet and closely along the surfaces of the annular magnet. The fluid flows in series, in parallel or any combination of in series and in parallel. The annular magnet may be a ring magnet, a disc magnet or a ring-shaped electromagnet. In order to maximize the magnetic treatment effect, the annular magnet is driven to spin in a direction preferable opposite to the direction of fluid flow.
