Abstract: The present invention relates to a new and novel process that combines several water treatment processes to biologically treat wastewater. The first treatment process is bioaugmentation using a select mixture of microorganisms grown from wastes collected from a Waste Water Treatment Plant (WWTP) to treat wastewater as it flows through its conveyance system. The second treatment process is employment of a flow control device that increases the holding capacity of the conveyance system to increase time for biological treatment and allow the contained water to be discharged at a controlled reduced and leveled rate. The third treatment process is a high-rate clarification system preferably using flocculating polymers to remove fine suspended solids from the wastewater that can be further treated in a series of containment structures positioned in a stream or riverbed to increase the treatment residence time.

Abstract: A process for removing fine particles and particulates from water. The process includes mixing a magnetic ballast, flocculant and water to form magnetic floc, and agitating the magnetic floc in a flocculation zone. A portion of the magnetic floc is collected on a magnetic collector in the flocculation zone. Another portion of the magnetic floc is directed downstream to a setting zone where the magnetic floc is settled. The settled magnetic floc is returned upstream of the settling zone where the returned magnetic floc is recombined with other magnetic floc in the flocculation zone. Ultimately, all, or substantially all, of the magnetic floc is removed by one or more magnetic collectors disposed upstream of the settling zone.

Abstract: A method and system for retrofitting an existing water treatment system having one or more biological reactor systems and one or more gravity clarifiers. To retrofit the existing water treatment system, the one or more gravity clarifiers of the existing water treatment system are converted to one or more biological reactors. In addition, one or more high rate clarifiers (HRCs) are added to the existing water treatment system. In some cases one or more high rate clarifiers are added downstream of the converted biological reactors, in other cases one or more HRCs is added upstream of the biological reactors, and in other cases a number of HRCs are added, upstream and downstream with respect to the biological reactors.

Abstract: A multi-stage process for removing dissolved contaminants and suspended solids from water employing a magnetic separation technique. The process includes two tanks and magnetic seed. In the first tank, water is clarified by magnetic technologies and in the second tank dissolved solutes are sorbed on magnetic seed.

Abstract: A nitrification-denitrification process using magnetic seeding and magnetic separation to treat water is provided. The process includes biologically converting ammonia to nitrates with a biofilm disposed on magnetic seed. Suspended solids are removed by mixing flocculant and magnetic seeds with the water and magnetically removing floc formed floc from the water.

Abstract: A two-step chemical precipitation process involving hydroxide precipitation and sulfide precipitation combined with “field separation” technology such as magnetic separation, dissolved air flotation, vortex separation, or expanded plastics flotation, effectively removes chelated and non-chelated heavy metal precipitates and other fine particles from water. In the first-step, the non-chelated heavy metals are precipitated as hydroxides and removed from the water by a conventional liquid/solids separator such as an inclined plate clarifier to remove a large percentage of the dissolved heavy metals. The cleaned water is then treated in a second precipitation step to remove the residual heavy metals to meet discharge limits. In the second precipitation step, any metal precipitant more effective than hydroxide for metal precipitation can be used.

Abstract: A system and process for utilizing a magnetic separation technique in a batch treatment process to clarify water. The system includes a tank, a mixing device, a shearing device and magnets. Water held in the tank includes magnetic floc having magnetic seed incorporated therein. The magnetic floc settle in a lower portion of the tank and clarified water is decanted from the tank. A shearing device shears the magnetic floc producing magnetic seed and sludge. A magnetic field retains the magnetic seed while the sludge is discharged from the tank. The retained magnetic seed are reused in subsequent batches of water.

Abstract: A water treatment system that utilizes magnetic seeding and magnetic separation to treat water. A magnetic collector is provided for collecting magnetic floc from the water being treated. A floc removal device in the form of a scraper is magnetically held adjacent to or in contact with the magnetic collector for scraping magnetic floc from the magnetic collector. Also disclosed is a disk type magnetic collector that includes a plurality of spaced apart magnetic disks supported on a shaft. A plurality of hook shaped floc removal devices are supported on the shaft with each hook shaped floc removal device being disposed between two magnetic disks or at least adjacent one magnetic disk. The hook type removal devices are spaced so as to engage an adjacent surface of a rotating magnetic disk. As the disk type magnetic collector is rotated, the hook type removal devices engage magnetic floc collected on the surfaces of the magnetic disks and scrape the magnetic floc from the disks.
