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

  • Upgrading A 100-Year-Old Pump Installation In New Orleans

    Finding just the right pump for an application can be quite a challenge, especially when the building presents several constraints. Sulzer updated a near antique installation.

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

  • EZ Valve Installed To Maintain Medical District's Water Supply

    When a North Texas city identified the need to create a permanent control point as well as isolate an area so a repair could be made to a water main, they called on Texas Hot Taps for a solution.

  • City Of Windsor, Ontario, Improves Water Quality In Great Lakes With PolyBlend® Polymer Preparation System

    The City of Windsor in Ontario, Canada, owns and operates two wastewater treatment plants.

  • Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years

    The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

  • Why A Little Knowledge About Sensors Can Be A Dangerous Thing

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  • Precision Under Pressure: Engineering Custom Solutions For Pipe Emergencies

    Emergency pipe repairs demand speed and accuracy. Custom engineered fittings ensure reliability in non-standard conditions, minimizing downtime, avoiding costly damage, and restoring service with precision and efficiency.

  • Michigan Utility's New Pumps Underscore Advancements In Wastewater Handling

    Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

  • Plant Operations And Maintenance Staff Benefits From New Headworks

    The high cost of maintenance and unsatisfactory performance of the aging equipment in the Bonnybrook headworks made it clear that significant changes were in order. The older poorly performing headworks allowed screenings to pass to the downstream process units causing operational and maintenance problems. By installing the Huber RakeMax® and matching WAP washpress, Calgary’s process performance immediately improved.

  • Seal The Deal: Shielding Against A Mag Meter's Achilles Heel

    When it comes to metering water flow — drinking water or wastewater — full-bore mag meters offer many advantages. While the underlying technology based on Faraday’s Law of electromagnetic induction is shared among all styles of full-bore mag meters, specific implementations have impacts on longevity and accuracy. Here is what to look for when the time to choose arrives.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Dissolved Air Flotation (DAF) systems remove suspended solids, fats, oils, greases and non-soluble organics by a process of dissolving air into water under pressure.

The WWETCO FlexFilter™ from WesTech uses compressible media to provide an efficient new solution for CSO, Primary Treatment, Tertiary Treatment and Industrial Water Pretreatment. The FlexFilter™ is a simple gravity system with a robust design requiring no moving parts. The combination of tapered media compression, porosity gradient within the media bed and a low flow backwash system make the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.

The TrojanUVFlex is designed with features to make installation and operation simpler, faster, and more cost-effective than ever before. Built on the proven TrojanUV Solo Lamp Technology platform, TrojanUVFlex allows for energy-efficient high-intensity delivery of UV light in an extremely compact footprint.

Pentair is pleased to announce the launch of the Hydromatic® HPE Series of premium-efficient solids-handling pumps. This series, available up to 200 hp, has been engineered for lower lifecycle costs, increased serviceability, and increased pump life.

DELUMPER® LP crushers reduce hard or soft, heat sensitive, sticky or wet agglomerates and lumps at high volume. These straight-through units employ extended cutting teeth that rotate completely through a heavy bar cage. Oversized solids up to the unit’s full input opening size are reduced by this powerful processor. With each rotation, the teeth clean the slot openings making the unit automatically self-clearing. Optional hardfacing is available.
