New liquid phase-based processes to regenerate spent AC have been conducted. Two liquid processes, competitive adsorbate displacement and supercritical fluid (SCF) regeneration, will be discussed.
Beringer Wine Estates, St. Helena, Calif., improved filtration effectiveness in its diatomaceous earth (DE) unloading and winery waste filtration area by an automated bulk bag unloader and flexible screw conveyor.
An oily water treatment facility on the Sabine River near Port Arthur, Texas, was not in compliance and had a large inventory of wastewater on site.
For a long time, the commercial and industrial (C&I) markets have been accepted as one sector of the water industry. Although considered different from such other markets as residential, agricultural and wastewater, there is a large murky area when being separated from each other.
With the recent proposals to create standards for the C&I markets comes the question of whether C&I should continue as one sector or be severed into separate entities. If a separation is in order, should it be determined by the application, flow rate or size of the equipment?
The membrane processing technologies of microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) are widely used to separate suspended and dissolved materials from water solutions in numerous industrial, medical and drinking water applications.
Off the coast of Washington, 32 families on Guemes Island were faced with an aging well that was drawing salt water into its system. Because groundwater is scarce on the island, residents had to rely on what little rain water soaks into the ground.
Granular activated carbon (GAC) is commonly used for removing organic constituents and residual disinfectants in water supplies. Activated carbon is a favored water treatment technique because of its multifunctional nature and the fact that it adds nothing detrimental to the treated water.
The increasingly broad range of requirements for water quality has motivated the water treatment industry to refine existing techniques, combine methods and explore new water purification technologies including desalination.
A PEP SMF-FG-24 media filter from Process Efficiency Products, Inc., was installed on the remote sump to reduce biocide costs at the dairy.
Filtration is an important part of most water treatment systems. Filters range from simple cartridge systems to large commercial/industrial multi-tank systems, not to mention the large municipal systems that filter drinking water.
