IMPROVED DISSOLVED AIR FLOTATION SYSTEM AND METHOD
Aspects and embodiments of the present invention are directed towards systems and methods for water treatment. In accordance with some embodiments, a water treatment system comprising an air dissolving pump, a relaxation pipe, and a dissolved air flotation unit may advantageously remove dissolved and suspended contaminants from a treatment water. Aspects and embodiments of the present invention may be used in seawater desalination.
This invention provides for sulfate removal from a water source by a reverse osmosis (RO) or nanofiltration (NF) process where the concentrate stream is treated to precipitate and remove reject sulfate and recycle the discharged concentrate water and any backwash water used to clean a filter used to prepare feed water for the RO or NF process.
An electrical purification apparatus and methods of making same are disclosed. The electrical purification apparatus may provide for increases in operation efficiencies, for example, with respect to current efficiencies and membrane utilization.

An electrochemical separation system may be modular and may include at least a first modular unit and a second modular unit. Each modular unit may include a cell stack and a frame. The frame may include a manifold system. A flow distribution system in the frame may enhance current efficiency. Spacers positioned between modular units may also enhance current efficiency of the system.

Reverse electrodialysis (RED) may be used to neutralize acid and caustic effluent waste streams, such as in the semiconductor industry. Power may be generated while waste streams are treated by converting chemical energy into electric energy. A bipolar membrane may be integrated into the RED system. Alternatively, an anion exchange membrane and a cation exchange membrane may be overlapped and used in place of a bipolar membrane. A cell pair with four membranes and four chambers, without a bipolar membrane, may also be implemented.
The inventive process scheme and its various embodiments described herein will comprise filtering a selenium containing water by reverse osmosis or nanofiltration to produce a primary permeate stream at least meeting the water stream effluent discharge requirements of the location and a concentrate stream containing the removed selenium and other species, a RO or NF concentrate treatment specific to the case which will treat and reduce the selenium content of the concentrate, optionally in conjunction with a sulfate removal process, and result in a highly concentrated sludge or other output, and a selenium depleted aqueous overflow stream, a portion of which will be combined with the primary permeate stream so that the selenium content of the combined stream does not exceed the local requirement, and the reminder of the selenium depleted aqueous overflow stream will be returned to be combined with the selenium containing water entering the inlet of the primary reverse osmosis treatment.
Ultraviolet reactors having an ultraviolet light source for treating a fluid are disclosed. In one embodiment, a reactor is disclosed which includes a vessel having an inlet for receiving fluid and an outlet for discharging fluid. The vessel further includes a plurality of segmented baffles. The baffles further include a partial circumferential edge section that terminates in a vertical edge section to form right and left segmented baffles. The left and right segmented baffles are arranged in an alternating pattern in the vessel to provide plug flow and enhanced radial mixing.

Electrochemical separation devices are configured for lower energy consumption. Techniques for reducing shadow effect may involve providing distance between a spacer screen and an adjacent ion-selective membrane. A spacer having a screen that is thin relative to a surrounding frame may be used. Mild pressure may also be applied to a compartment to promote distance between a spacer screen and an adjacent ion-selective membrane.

A method and system of treating wastewater is disclosed. The treatment system has a nitrification-denitrification system comprising a sorption system, a biofilm system, and an anaerobic digester that digests or converts at least a portion of the solids or sludge from the sorption system and biofilm system. The method can comprise providing a wastewater to be treated and denitrifying the wastewater in a first biological reactor to produce a denitrified mixed liquor, nitrifying the denitrified mixed liquor with a nitrifying biofilm on a earner and biosorbing undesirable constituents from the denitrified mixed liquor with a suspended biomass in a second biological reactor, and separating a first portion of the nitrified mixed liquor in a separator to produce a solids-rich sludge and a treated effluent having a total nitrogen concentration of less than about 10 milligrams of elemental nitrogen per liter.
Aspects and embodiments of the present invention are directed to apparatus and methods of filtering a fluid to reduce a level of at least one contaminant therein. The filtering of the fluid may be accomplished with a radial flow filtration column comprising a fluid chamber having an inlet, an outlet, and a side wall, an inner permeable retainer positioned in the fluid chamber, an outer permeable retainer positioned in the fluid chamber spaced apart from and surrounding the inner permeable retainer, a media bed compartment formed between the inner permeable retainer and the outer permeable retainer, and an adjustable element biased into the media bed compartment and configured to maintain a predetermined packing density of a media bed to be disposed within the media bed compartment.

Highly energy efficient electrodialysis membranes having low operating costs and a novel process for their manufacture are described herein. The membranes are useful in the desalination of water and purification of waste water. They are effective in desalination of seawater due to their low electrical resistance and high permselectivity. These membranes are made by a novel process which results in membranes significantly thinner than prior art commercial electrodialysis membranes. The membranes are produced by polymerizing one or more monofunctional ionogenic monomers with at least one multifunctional monomer in the pores of a porous substrate.

An ultraviolet reactor (22) for treating a fluid. The reactor includes a vessel (24) having an inlet (48) for receiving fluid and an outlet (58) for discharging fluid. The reactor (22) further includes an ultraviolet light source (54) and baffle plates (26, 28, 30). The baffle plates include holes (38) arranged in a predetermined pattern for providing plug flow in areas in the reactor near the ultraviolet light source (54).
A high recovery sulfate removal process comprises treating a feed water stream conditioned with antiscalant from a source with a reverse osmosis membrane system to produce a purified water permeate stream and a reject stream containing the retained or rejected ions and organic matter. The reject stream is further treated to remove dissolved and suspended species. The reject stream flows to a desaturation/ clarification process. A preferred process includes a constant stirred tank reactor (CSTR) where co - precipitation agent is added followed by a clarifier. Water recycled from the clarifier overflow is blended with feed water stream. The removed solids are collected as sludge or a slurry and disposed of in a manner consistent with applicable regulations.
