WOL_key-west_cs_385x250 Key West Resort Utilities Maximizes Reuse And Nutrient Recovery

Water scarcity poses unique challenges to KW Resort Utilities Corp. (KWRU), the utility firm that provides wastewater management, wastewater recovery, and wastewater treatment in the region. KWRU began operation in the late 1960s and has worked hard over the decades to keep up with wastewater needs as population and tourism have boomed, spurred by land reclamation and development. 

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Options For Retrofitting Existing Sand Filters With Pile Cloth Media

    While effective, sand filters can be prohibitively expensive to maintain. For this and other reasons, many WWTPs are retrofitting existing sand filters with pile cloth media filtration (PCMF).

  • Wipe Out Pump Clogs With The Duperon Dual Auger System

    The Dual Auger System protects pumps and downstream equipment by extracting flushable wipes and other problematic material from raw sewage without grinding.

  • Clearing Channels And Tanks Of Rag And Fiber Produces Benefits Beyond The Tanks

    Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products. 

  • AOP Removal In Aquifer Remediation

    In this case study, read about a successful pilot test in Long Island, New York, removing 1,4 dioxane from water. The technology used offers improved efficiency, reduced maintenance, and ongoing monitoring for reliable water treatment.

  • City Of Fayetteville Replaces UV Treatment System With BlueInGreen's HyDOZ Solution

    After researching different ozone systems, plant officials ata 12 MGD wastewater plant in Arkansas chose to install BlueInGreen’s HyDOZ technology in order to more efficiently meet current permit requirements, as well as prepare for future legislation.

  • Fairbanks Nijhuis Protecting New Orleans

    Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

  • Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

  • Wastewater Treatment Plant Reduces Energy Consumption, Noise With Turbo Blower Technology

    Built in 1974, the Blue River Wastewater Treatment Plant in Silverthorne, Colorado, provides wastewater services to the communities of Silverthorne, Dillon, Dillon Valley, Buffalo Mountain, and Mesa Cortina. Faced with rising energy costs and aging equipment, the Silverthorne-Dillon Joint Sewer Authority (JSA) identified a need to replace the plant’s original multistage centrifugal blowers with new technology that would reduce energy consumption and provide steady and reliable operation.

  • Macerator Explodes, Monster Sludge Grinder Takes Over

    The Coeur D’Alene, ID, wastewater treatment plant was having continual problems with two sludge macerators, in part because of the durability of the macerator.

  • Newterra Keeps Large Rapid Transit Project On Track

    Discover how a custom-designed Construction Dewatering System with minimal site footprint was delivered within approximately 11 weeks. 

WASTEWATER APPLICATION NOTES

  • Recording & Control: Online Data Recording And Control In Anaerobic Digestion Processes

    Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

  • Scrubber Application

    This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

  • Process Optimization For Flow Measurement

    The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water. 

  • Repair Or Rethink

    The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

  • Nitrogen-Reduction Treatment Systems For Long-Term Operations

    The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

  • Bringing Efficiency And New Confidence To BOD₅ Analysis

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  • Combining Decentralized And Centralized Wastewater Treatment Strategies To Solve Community Challenges

    To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

  • MEGA-STOP Bell Protection System Aids In Pipe Joint Assembly

    Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

  • Application Bulletin: Reverse Osmosis

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

  • AquaSBR Systems Above 10 MGD

    This application note will explore installations of AquaSBR Systems worldwide in a variety of municipal and industrial applications.
