A food processor was experiencing low hydraulic residence times at one of their anaerobic digesters during the discharge of waste activated sludge. a feasibility study identified that the most cost-effective option was to thicken and anaerobically treat thickened waste activated sludge (TWAS) in a new digester designed specifically for that purpose.
A system for anaerobic digestion of slops, water treatment, and biogas utilization was designed to meet regulations, displace fuel-oil, and cut greenhouse gases at a Central American rum distillery.
Advanced oxidation systems using hydrogen peroxide (peroxide) and ultraviolet (UV) light are designed to inject hydrogen peroxide in controlled ratios to the water, then mixing the peroxide, and exposing the water and peroxide solution to UV radiation to form hydroxyl radicals (•OH). Peroxide and hydroxyl radicals are strong oxidizing agents capable of oxidizing 1,4-dioxane and several volatile organic compounds (VOCs). The advanced oxidation process is suitable for groundwater remediation with pump-and-treat, water treatment, and industrial wastewater treatment. Treatment with UV/Peroxide may offer technical advantages over ozone based treatment systems.
Perchlorate is a known thyroid gland disruptor and its concentration is regulated in soil and groundwater. Read more about the water treatment options for perchlorate impacted groundwater. Continue reading
Description Ion Exchange is a process in which ions of a species are displaced from an insoluble exchange material (ion exchange resin) by ions of a different species in water. The removal of target ions is achieved through commercially available … Continue reading
The advanced oxidation process is a proven technology for the oxidation of a wide range of compounds in water and groundwater impacted with BTEX, MtBE, TPH-g, total petroleum hydrocarbons as diesel (TPH-d), tert-butyl formate (TBF), tert-butyl alcohol (TBA), tert-amyl methyl ether (TAME), diisopropyl ether (DIPE), polyaromatic hydrocarbons (PAHs), trimethylbenzene, 1,4-dioxane, trichloroethylene (TCE), perchloroethylene (PCE), 1,2-dichloroethene (1,2-DCE), 1,1-dichloroethene (1,1-DCE), vinyl chloride, and tetrahydrofuran.
SVE is an in-situ remediation technology designed to remediate soils impacted with VOC’s including gasoline range organics, and chlorinated hydrocarbons. This technology works by extracting a soil vapor from the subsurface at a high vacuum and remediate soil in the vadose zone.
Feasibility Study, Sugar Mill Wastewater Treatment, Nicaragua Sugar Estates Limited (Ingenio San Antonio), Central America
After the Nicaraguan government published new wastewater discharge regulations, a Nicaraguan Sugar Mill was required to select a new wastewater treatment plant. A feasibility study consisting of a wastewater characterization program and a feasibility study was conducted to identify the most cost-effective technology for wastewater treatment.
A chemical metering system used for chemical precipitation of phosphorous required upgrading to accommodate a higher wastewater flow and phosphorous loading. A new chemical metering system consisting of ferric chloride storage tanks, pumps were designed, specified and constructed.
The site is an active oil and natural gas production property that currently re-injects approximately 135,000 barrels per day (BPD) of produced water. As a result of limited reinjection capacity, the facility was required to treat and discharge up to … Continue reading
