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.
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.
A wastewater treatment process at a potato processing plant located in Argentina was experiencing continuous upsets with their activated sludge treatment system. A hands-on training program was implemented to teach operators to monitor and control the two existing biological treatment processes consisting of a low rate anaerobic wastewater treatment pre-treatment and an activated sludge treatment system.
To improve the performance of an existing water treatment plant, a sludge dewatering and anaerobic digesting system was designed and constructed. Continue reading
