Desalination Serves Coastal Argentine City

When a series of water crises in 2014 disrupted conventional utility services in the coastal Argentine city of Caleta Olivia, the city needed a way to ensure an uninterrupted water supply.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • White Paper: Stormwater Retention For A Modular Green Roof Using Energy Balance Data
    White Paper: Stormwater Retention For A Modular Green Roof Using Energy Balance Data New York City stormwater is a major cause of water pollution in the harbor and estuaries. This is due to the vast areas of impervious surfaces (e.g., rooftops, pavements, sidewalks) that rapidly shunt runoff into the combined sewage overflow (CSO) system.
  • Case Study: Vortex Wastewater Pumps Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.
  • Case Study: CST Handles Combined Sewer Pre-Treatment For City Of San Francisco
    Case Study: CST Handles Combined Sewer Pre-Treatment For City Of San Francisco The San Francisco Department of Public Works required a cost-effective solution to pre-treat the downstream lift station system from trash, debris, vegetative material, and primarily sediment, which was destroying grinder pumps and occluding the downstream conveyance pipes at a huge cost to the city.

    Freeport Wastewater Treatment Plant Saves Money And Energy With Hybrid Blowers

    Best known as the home of outdoor retailer L.L. Bean, the community of Freeport is a popular summer destination on the shore of Casco Bay in southern coastal Maine. In 2010, the Freeport Sewer District brought in engineering firm Woodard & Curran (also of Freeport), to conduct an energy analysis of the Freeport Wastewater Treatment Facility. The assessment revealed that the Freeport plant consumed more than 8.9 kBtu per gallon of wastewater treated, more than double the national average of 4.1 kBtu per gallon. While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80 percent of the electricity consumption.

  • Brewery Installs Complete Aerobic Treatment System To Meet City Requirements
    Brewery Installs Complete Aerobic Treatment System To Meet City Requirements

    Worthy Brewing approached ClearBlu Environmental at the 2011 Craft Brewers Conference. The brewery was still in its planning stages, but knew that some extent of wastewater treatment would need to be incorporated to satisfy city requirements. ClearBlu worked closely with the facility’s architect and engineers to incorporate plans and allocate space for a complete aerobic treatment system at the facility. Upon startup, the brewery was only required to implement a pre-treatment system, which includes solids screening, settling, and automatic pH balancing. They have all ruggedized equipment that will support their system through the brewery’s expected expansion.

  • Case Study: First Municipal-Industrial Water Reuse Project In Virginia! Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water
  • CA 71 With Ammonium And Nitrate Measurement Metro Waste Reclamation District is one of the largest wastewater treatment plants between the Mississippi River and the west coast. Treated water is discharged into the South Platte River, and contributes 90% of the river’s annual flow at the point of discharge.
  • Article: Process Cooling Of Engine/Generator Sets With Reuse Water Located along the banks of one of the largest tributaries to the Mississippi River, this 100 MGD (million gallons per day) wastewater treatment plant (WWTP) has a large demand for service water with low suspended solids. Nearly 3 MGD of water are needed for various on-site services but perhaps none as important as cooling large V-12 internal combustion engine/generator sets.
