Fluid treatment systems and components are provided for a removal of solid matter from water or other fluids in which a chemical or chemicals may be introduced into the fluid under pressure to coagulate and/or conglomerate the solid materials and cause them to be dropped out of the treatment system and be removed. The fluid treatment system can include: an equalization chamber receiving a wastewater; a clarification chamber receiving a partially separated water from the equalization chamber; a mixing tube having an inlet end and an outlet end; and a sludge detector.

An auto jartest analyzer includes a plurality of water sample reaction equipment, coagulant providing/controlling equipment and a coagulant concentration analysis device. The coagulant providing/controlling equipment provides coagulant of different concentration to the plurality of water sample reaction equipment to allow contaminants in a water sample of the water sample reaction equipment to precipitate. The coagulant concentration analysis device analyzes turbidity measurements for the plurality of water sample reaction equipment and determines if they meet predetermined analysis criteria, so as to figure out an optimal concentration of coagulant currently required to be added to the water sample. This thus achieves automatic analysis of an addition concentration of coagulant to be added to the water sample, which not only improves operational efficiency but also makes the analysis result more accurate.

An etching solution recycling system for a wafer etching apparatus is provided. The etching solution recycling system includes a settling tank, a seed provider, and a fluid control unit. The settling tank is connected to an etching tank of the wafer etching apparatus and configured to receive an etching solution from the etching tank. The seed provider is configured to provide at least one seed crystal into the settling tank to reduce the silicate concentration in the etching solution in the settling tank. The fluid control unit is configured to deliver the etching solution in the settling tank back into the etching tank.

This sampling device for a coagulation treatment device (1) comprises at least: a sealed-type coagulation reaction tank to which is introduced water to be treated to which a flocculant has been added; and a solid-liquid separation tank to which is introduced the water to be treated that has been drawn from the coagulation reaction tank, the sampling device comprising a sampling tank, a coagulation sensor installed inside the sampling tank, and a water sending pipe (43) which sends, from the coagulation reaction tank of the coagulation treatment device to the sampling tank, a part of the water to be treated inside the coagulation reaction tank.

A filtering system capable of removing particulates from a water slurry is disclosed. The filtering system comprises a base plate, the base plate comprising a sealing surface and a slurry inlet. A flexible vessel is configured to seal to the sealing surface, and an interior cavity, wherein the flexible vessel is formed of a flexible filtering material capable of retaining particulates. The flexible vessel permits liquid entering through the slurry inlet to pass through the filtering material and is capable of withstanding an internal pressure sufficient to form a particulate cake without rupturing the flexible vessel. A sealing system is provided for retaining an upper portion of the flexible vessel against the sealing surface. The filtering system may be part of a portable system that includes a cart, hoses, piping, a pneumatic pump and a control panel.
