A pre-filtration apparatus and system using dissolved oxygen ozone-treated water processed through an oxygen saturator having a flow distributor for even distribution of the water. Fully saturating the water with excess oxygen and injecting this high-pressure mixture into a blender have a lower pressure atmosphere to produce a plurality of micro-bubbles known as white-water. Influent water enter the blender through nozzles aligned with the injection of the high-pressure water to blend with the white-water. The blend passes into a hydrocyclone separator from the bottom, spirals up separating waste water from the clean water. Clean water is discharged; waste water is passed to a recovery unit for further processing and recycled. Volatile gas from dissolved toxic chemicals adsorbed by the micro-bubbles is discharged through a carbon filter recovery process.

Chemical removal and suspended solids separation pre-treatment system

A method and apparatus for treating raw influent water to remove particles, algae and toxic chemicals from the water. Basically, air is dissolved in recirculated water under high pressure in an air contactor unit, the air saturated water is intimately mixed with the raw, particle bearing, water in a particle mixing system, and the water, particle and air mixture is passed through an air bubble separator wherein bubbles formed when the pressure on air saturated water is reduced carry away toxic gases and particulate material. If desired for further cleaning the water can be sent through a second series of air contactor, particle mixer and air bubble separation, but with a gas comprising ozone to further remove suspended particles and non-volatile dissolved organic matter. In order to improve mixing of the particles and the air saturated water passing through tubes, preferably a pattern of dimples is formed on at least part of the interior wall of the tubes. Upon completion of the process the water is ready for use or for further filtration in a conventional filtration plant.

An all digital physical parameter sensing network. Sensors under control of a central computer measure factors such as temperature, pressure, flow rate, filter efficiency and the like at numerous locations in a system such as a water treatment plant. Each sensor is precalibrated with voltage offset information, sensitivity variations, corrections for nonlinear behavior, etc. stored in memory at the sensor. All sensors generate corrected voltage signals conforming with the measured physical parameter, so that any sensor can be replaced without requiring recalibration. Basically, the system comprises a central computer, a communications interface between the computer and a single bus, plural sensor nodes along the bus each including a sensor for sensing a physical condition and processing the sensed information to correct for sensor individual characteristics and for transmitting the corrected sensed information to the central computer.

The disclosure is directed to a system for sensing specific properties of a process flow without flow interruption. A plurality of sensors each sensing a different property of the process flow are arranged in close proximity within the process flow. The sensors each produce an electrical output of their monitored property. Magnetic transformers are provided to prevent cross-talk between the sensor's outputs. Data from the sensors is processed and presented for use in controlling the properties of the process flow and for monitoring.

Integrated arrangement for monitoring without interrupt process flow by

A generally columnar chamber for uniformly mixing a gas, such as ozone, into a liquid, such as water. The mixing chamber is assembled from a series of round tray sections each having an outer and an inner helical conduit sections and a central vertical tube section. The trays are stacked and secured together to form a continuous outer helix, inner helix and central column. A port at the bottom of the column directs liquid into the outer helical conduit spiraling up to the top of the column where a crossover port directs the liquid into the inner helical conduit downwardly to a cylindrical sump. The outlet of the inner helix into the sump is angled so as to create a vortex in the sump, forcing heavy particles outwardly to the sump wall. Heavy particles are allowed to migrate down the wall to a collection region at the bottom of the sump for later removal. The liquid from the sump passes upwardly through an aperture plate or vortex buster into the vertical column and finally out an outlet at the top of the column. The vortex in the sump forces gas bubbles to the center of the sump from which they are directed upwardly through the column, carrying buoyant particles and continuing the gas/liquid mixing.

Method of mixing gases and liquids employing concentric helical flowpaths

A vortex system for separating particles of varied size and density from a liquid stream. A particle bearing liquid is introduced tangentially into one end of an elongated cylindrical chamber to form a rotating liquid vortex therein. An impeller at one end of the chamber reinforces the vortex flow. Either a series of tangentially oriented jets introducing a gas or a gas saturated liquid through the chamber wall or a rotating central chamber section further increases the vortex rotational flow. The vortex produces a heavy particle rich outer region, a gas and light particle rich axial region and a cleaned liquid annular region therebetween. The cleaned liquid flows out of the chamber through an outlet at the chamber end opposite end at which the particle bearing liquid is introduced. The heavy particles in the outer region and the gas and light particles in the axial region are each removed through an outlet. A variety of component orientations and auxiliary devices may be used to optimize system operation.

A system for counting particles entrained in a flowing fluid and for automatically calibrating the counting system is disclosed. A conduct through which a fluid carrying particles flows has a transparent section. A narrow light beam, such as a laser light beam, is passed through the transparent section to a detector, such as a photodiode, that detects light scattered by the particles. The scattering pattern is useful in counting the flowing particles and measuring other particle characteristics, such as size. The measurement system can be calibrated by passing the light beam through a transparent slide bearing a standard particle array to a detector, either the measurement detector or a second detector. The slide is moved at the same rate as the fluid flows, so that the scattering produced by the standard array is useful in calibrating the measurement of the flowing particles in a conventional manner. The calibration may be accomplished by deflecting, such as with a movable mirror, the light beam through the moving slide to a second detector or the body containing the conduit can be moved out of the way so that the slide can be moved across the original light path. A multiple solenoid valve may be provided to selectively direct the particle bearing fluid through the conduit, direct reverse flow of clean water or a gas, such as air, through the conduit to clean the conduit or remove any particle contamination or jams.

Method and apparatus for particle counting and counter calibration

A filtration system for water or other selected liquids that includes an ozone mixing station, a primary solids and gas separator and, if desired, a second vortex particle separator and filter system. The ozone mixing station includes a high efficiency ozone generator and a channel arrangement, such as a spiral tubular treatment coil, through which the ozone/liquid mixture passes to assure thorough mixing and provide time for effective treatment. The primary solids separator includes an offset inlet jet through which the liquid from the ozone treatment station is injected into a first circular chamber. The resulting rotating liquid vortex moves to a narrowed co-axial second circular chamber to cause heavy particles to concentrate at the outer perimeter then to a coaxial larger third circular chamber. The liquid exits through an annular outlet located around the chamber axis to prevent buoyant particles in the axial region and heavy particles at the outer periphery from passing out with the liquid. Gas collects in a cylindrical axial region with the lighter suspended particles in an annular region around the gas column. The gas phase is removed through an annular, variable, series of holes at the top of the chamber. The liquid from the solids separator may be passed to a filter system to further treat the liquid.

A system for filtering a liquid stream, typically drinking water from a natural source. The system includes a plurality of filter stations, each of which receives at least a portion of the influent liquid flow, passes the flow through a filter and passes the filtered liquid to an affluent line. When the filter has reached its capacity for removing particulate material from the liquid flow, preferably as determined by measurements of pressure drop across the filter media, a small quantity of the clean affluent liquid is passed through the filter in a reverse direction to back flush the filter media, with the flush liquid directed to a waste water line. Back flushing can be accomplished automatically under microprocessor control, using signals from a filter media pressure sensor. With a plurality of parallel filter arrangements, continuous flow to the affluent line is easily maintained, since the back flush cycle is short and all filter sets would not be in the back flush mode at the same time. The filter has a porous tubular core bearing filter media on the core surface. The core is housed in a canister having an entrance directing influent liquid into the canister tangential to the core and an affluent line connected to the interior of the core. This configuration provides improved filter media life and efficient reverse flow during back flushing.

An improved air dryer having a heat exchanger through which ambient air passes between an input and an exit. The air passing through the heat exchanger for drying is normally chilled by the cold side of a thermoelectric module attached thereto. The normally opposite hot side of the thermoelectric module is attached to a heat sink which includes a fan which pulls ambient air through the heat sink for dissipating the heat from the thermoelectric module. The air passing through the heat exchanger is cooled by the thermoelectric module to a temperature below its dew point, causing the moisture in the air to be deposited on the chilled air passage walls of the heat exchanger, where it is frozen. When the air passageway of the heat exchanger becomes substantially closed by the ice formation on the walls thereof, the current to the thermoelectric module is reversed, whereby the normally cold side becomes the hot side and vice versa and, simultaneously, the air exiting is directed from an exit path to an alternate exit path. The heated ice, the ice formed on the passageway of the heat exchanger, thaws and is removed through the alternate exit path. The cooling and heating is then alternately repeated during the operation of the dryer. A timer is used to control the alternate reversing.
