Factoring Temperature Into Water Chemistry Reading Accuracy
Factoring Temperature Into Water Chemistry Reading Accuracy

In water testing, readings that we believe to be reliable indicators are not always what they seem. Water that exhibits certain chemical or electrical characteristics at laboratory temperatures can provide entirely different readings in the field. Here is a quick review of what to look for in common water tests and why to consider automatic temperature compensation in the instruments used to collect them.

    I-BOx® 6000 Biological Odor Control System Removes Odors From Laguna SOCWA Lift Station

    After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.

    Sticking with Innovation That Works

    With a population of about 15,000, Steinbach is the third largest city in Manitoba and one of the fastest growing areas in Canada. The current system has been operating since 1993, an eternity in the world of technology. Because the wastewater department was already familiar with operating the existing Xylem/Flygt M&C SCADA system with Aquaview software and APP controllers, they decided to inquire what new technologies the company could offer.

  • FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  • Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue
    Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue

    In order to meet the anticipated effluent criteria required by the Pennsylvania DEP, the Newville Borough Water & Sewer Authority determined that its existing wastewater treatment facility needed renovations. By installing two continuous fill SBR tanks, the facility lowered total nitrogen below permit limits, reduced energy costs, and created a new revenue stream (selling unused nutrient allocations). Read the case study for full details.

  • How To Buy Right, Not Cheap When It Comes To Solids-Handling Pumps

    Companies using solids-handling pumps as part of their processes know that even though the pumps are typically moving trash and other waste products, the type of equipment used can be a huge business decision. Most applications warrant more attention than simply choosing the first pump that pops out of a catalogue. By The Gorman-Rupp Company

  • Combining Biosolids Waste Streams?  Not So Fast…
    Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.

  • Sludge Thickeners: The Good, The Bad, And The Smelly
    Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy
    Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Sludge Sampling For Polymer Selection – Critical For Project Success
    Sludge Sampling For Polymer Selection – Critical For Project Success

    Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment.  Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.

  • How To Boost Wastewater Treatment Capacity Within An Existing Footprint
    How To Boost Wastewater Treatment Capacity Within An Existing Footprint

    Municipalities can find themselves in a real bind when wastewater treatment operations are strained by population growth. That’s because facilities are either landlocked and can’t expand at their current location, or the prospect of building an addition isn’t in the budget. When the bottleneck is at the digesters — the tanks where microorganisms break down waste — there are some common-sense strategies treatment plants can employ to address those growing pains.

  • Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results
    Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

    When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.
