Pile cloth media filtration treats wet weather flows in real time, increasing capacity, improving removal efficiency, and helping utilities reduce reliance on limited stormwater storage.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • California's First Installation Of 2nd Generation ATAD

    Calera Creek Water Recycling Plant, located in Pacifica, California, recently retrofitted to the Thermal Process Systems’ ThermAer™. This is California’s first installation of the second generation ATAD system.

  • Water Agitation vs. F.O.G.: How Technology Is Solving A Costly Problem In Lift Stations

    Wastewater lift stations struggle with F.O.G. buildup, causing maintenance headaches. Continuous water agitation, like Kasco’s HydraForce™, prevents grease accumulation, reduces chemical use, and improves pump efficiency.

  • The DELUMPER®: A Sweet Success At ADM

    ADM Cocoa Plant in Hazle Township, Pennsylvania needed help with their cocoa bean production. The plant processes two and a half million pounds of cocoa beans each day, turning them into cocoa powder, cocoa butter, and chocolate liquor. The company needed a machine to process sugar with over-sized lumps that could occur in transport or storage. Unless these agglomerated clumps were reduced to a granular form, the process could not work dependably. The machine also had to handle the large quantity of sugar processed daily and be sanitary.

  • Addressing Fouling Challenges In Water Treatment With RO Membrane

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  • How Does The Force Balanced FLEX-TEND® Product Work?

    There are numerous configurations of flexible and expansion joints available to the design engineer. They include bellows joints, flexible hoses, bolted-mechanical couplings, and ball joints. In 1989 EBAA Iron, Inc. introduced the FLEX-TEND® joint (FT) flexible expansion joint product into the US market. Constructed of ductile iron, the product is comprised of two ball joints joined by an expansion joint. For the first time one product was available to protect pipelines and pipeline connections from differential movement resulting from seismic activity and soil expansion/contraction in areas of poor soil support, frost heave, and transitions from stable to unstable areas.

  • Getting A Handle On Sewer Overflows

    Wet weather events are a growing concern for wastewater treatment plant operators, but a new twist on cloth media filtration may provide the answer to their peak flow management problems.

  • Understanding Sustained Efficiency In Non-Clog Pumps

    This white paper will provide a review of pump efficiency and the benefit of self-cleaning hydraulics in wastewater pumping. 

  • Using ATP And NGS To Monitor Nitrification

    China Steel Corporation, a steel producer in Taiwan, produces wastewater that is high in organics, ammonia, solids, and other waste products. The wastewater is treated on-site using a series of biological treatment processes. The variable influent quality can make it challenging to meet treatment objectives.

  • Water Into Wine

    As a young engineer on a farm in California's Central Valley grappling with the challenge of injecting fertilizer into irrigation water, Angelo Mazzei didn't consider how his career would ultimately turn his knowledge of water into a deep involvement in wine. But since he crafted first high-efficiency venturi injectors in the 1970s in his garage to help improve water, fate and business have pulled Angelo Mazzei toward wine from every direction.

  • Odor Problems Solved At Santa Margarita Water District's Chiquita Water Reclamation Plant In Orange County, CA

    Santa Margarita Water District (SMWD) is the second largest water district in Orange County, California, providing water and wastewater services to more than 155,000 residents and commercial enterprises. When a new housing development was planned adjacent to SMWD’s 9.0 MGD Chiquita Water Reclamation Plant, the District initiated plans for enhanced odor control solutions. District staff identified the primary process area (grit removal and primary clarifiers) as a significant contributor to odor emissions.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

OI Analytical’s CNSolution™ 9310 On-line Cyanide Analyzer is designed to measure available cyanide in precious metal leaching solutions by USEPA Method OIAA-1677 and ASTM D 6888-09. Unlike traditional techniques, the gas-diffusion amperometry technique used in these methods is free of interferences from copper and metallic sulfides. The 9310 On-line Cyanide Analyzer displays results in real-time and has a single piece zero-maintenance reference electrode, which simplifies instrument maintenance.

LST300 represents the future of level measurement. While using intelligent compact transmitters has always been attractive, certain limitations prevented their use in many applications. LST300 removes those old obstacles. Whether you have the risk of flooding or corrosive materials in the process, LST300 survive these conditions easily. With metal at the top and PVDF at the bottom, LST300 is the first compact ultrasonic to be resistant to corrosion on the entire instrument. Ingress protection approvals up to IP68 (optional) ensure the entire device can survive flooding.

The Schreiber Washer/Compactor washes out organics and dewaters screenings in a batch sequence. Screenings enter the top of the unit and are agitated by a rotating shaftless screw in a trough being supplied with wash-water. As the screw rotates in a forward and reverse motion providing agitation, entrained organic material is released from the screenings. The organics now in suspension are drained back to the process stream for treatment by the process equipment. The washed screenings are transferred over a barrier at one end of the wash trough into the compactor section below. The screenings are subsequently dewatered by the action of a compactor screw, gravity and conical discharge, and then conveyed through a larger diameter discharge pipe to a screenings container. The washed and compacted screenings material is significantly reduced in both volume and organics, resulting in disposal cost savings, and will pass the Paint Filter Test.

Installed under pressure, up to 250 psi, the Insta-Valve 250 increases operator safety, limits environmental impact, and saves up to 100% of the costs related to system shutdown.

The ORCA solution ensures consistent and precise chemical dosing with enhanced service and system automation to handle changing levels of hydrogen sulfide in real-time. This provides superior odor control performance and protects critical water infrastructure.

De Nora Water Technologies’ EST dry emergency scrubbers are engineered to meet national codes for the mitigation of hazardous gas releases from pressurized 150-pound cylinders and one-ton containers of chlorine, sulfur dioxide, ammonia and other toxic gases.
