iStock-1054574144 Water Utility OT vs. IT — It’s Not A Battle, It’s A Balance

The chemistry of optimizing water/wastewater treatment extends far beyond chlorine and oxygen. It also involves synthesizing productive insights from the flood of IT data generated by operational technology (OT) sensors, instruments, and control systems. Here’s how better operational intelligence strategies are helping IT and OT personnel collaborate to make processes more cost-efficient.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Integrated Level Solutions For The Future

    Smarter measurement supports safer, more efficient and more sustainable operations, improving uptime and extending servicelife, whatever the industry sector.

  • 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.

  • Ozone Gas Flow Monitoring For Water Treatment Systems

    Many municipal water treatment plants utilize Ozone Treatment Systems to produce clean water for residential and industrial users. While all the various types of water treatment systems have their advantages and disadvantages, Ozone (O3) systems provide excellent disinfection and avoid some of the chemical byproduct problems experienced with the use of chlorination. 

  • Time-Tested Technology: 25 Years of Trickling Filter Media Success

    The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.

  • Recognized Results Based On Quality Assurance And Quality Control

    Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.

  • Biologically Engineered BioFilm Modifications For The Enhancement Of Collection System Transformations And Impacts On BNR Wastewater Treatment Increased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower during bioaugmentation
  • Reconditioned And Rehabbed Filters Succeed At Large Treatment Plant

    A large treatment plant includes several treatment processes that contribute to providing quality recycled water pursuant to the state of California Title 22 regulations. Major treatment processes include raw wastewater pumping, preliminary treatment, primary treatment, secondary treatment, tertiary treatment with Parkson DynaSand® filters, and disinfection.

  • Southern California Water District Reduces Polymer Usage 30% With Polyblend® Polymer Activation System

    Santa Margarita Water District (SMWD), located in southern California’s Orange County, between Los Angeles and San Diego, provides drinking water and wastewater services to over 165,000 residents and businesses. SMWD approached UGSI Solutions about a Polyblend® Polymer Activation System trial at their 3 A Water Reclamation Plant.

  • Historic Town Remedies FOG Problem

    Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.

  • Finding A Perfect Fit For Mix-And-Match Piping

    Today’s water/wastewater piping options offer numerous advantages in terms of cost, performance, and anticipated service life. Unfortunately, utilities must still deal with what’s already in the ground — steel, cast iron, ductile iron, asbestos cement, plastic, concrete, and even wood. Here are guidelines on making transitions between old and new pipes of varying sizes and materials as smooth as possible.

WASTEWATER APPLICATION NOTES

These drainage structures include curb inlets, drop inlets and rectangular

The patented Foambuster uses the same glass-lined ductile iron nozzles as Rotamix but also uses a stainless steel splashplate located below the nozzle to deflect the nozzle discharge and create a broad spray of sludge, which wets and breaks up foam forming on the surface of the digester. Digester sludge is pumped through the Foambuster either by the Rotamix Chopper Pump or by a separate Chopper Pump. When the Foambuster is used in conjunction with a tank mixing system, which produces a rotational mixing pattern in the tank, only one spray nozzle will be required for effective foam control.

ADVANCE™ Series 200 gas feeders are designed for or automatic gas regulation. Automatic operation requires a simple addition of a motorized control valve.

S & N Airoflo has supplied floating brush rotors to the municipal and industrial markets for aeration for over 15 years. Our aerators provide very high oxygen transfer and mixing rates to deliver better efficiency with less horsepower, typically achieving 30% to 60% lower energy costs

ACTIFLO® is a high rate, compact process developed by Veolia Water Technologies. The process operates with microsand which enhances floc formation and acts as a ballast to aid in rapid settlement of coagulated material.

The Fox DDC-Sensor™ is a new state-of-the-art sensor technology used in the Fox Model FT1 Thermal Gas Flow Meter. The DDC-Sensor™, a Direct Digitally Controlled sensor, is unlike other thermal flow sensors available on the market. Instead of using traditional analog circuitry, the DDC-Sensor™ is interfaced directly to the FT1 microprocessor for more speed and programmability. The DDC-Sensor™ accurately responds to changes in process variables (gas flow rate, pressure, and temperature) to determine mass flow rate, totalized flow, and temperature.
