495 Growing Through Change in Water Treatment with Mark Lewis, Part 1
Scaling UP! H2O
Change is unavoidable, but uncertainty does not have to control how water treatment professionals respond to it. Mark Lewis returns to share what he learned when Southeastern Laboratories was acquired by CRB Water—and how employees can remain valuable, informed, and open to opportunity during a business transition. Navigating an Acquisition from the Employee’s Perspective Southeastern Laboratories began exploring a buyer because its owners wanted to protect the company and approximately 30 employees. When CRB Water entered the picture, employees naturally wondered what...

491 Environmental Microbiology and Legionella: Managing Building Water Risks with Dr. Rajiv Sahay
Scaling UP! H2O
Reliable Legionella results begin long before a sample reaches the laboratory. of explains how building conditions, field collection practices, and laboratory methods influence the quality—and usefulness—of the data water professionals receive. Building Water Conditions Shape the Risk Modern buildings rely heavily on controlled mechanical systems, yet water can remain an overlooked part of the indoor environment. Stagnation, low flow, dead legs, temperature, pH, disinfectant residuals, corrosion, and accumulated organic material can all influence biofilm development and microbial...

490 From Plans to Prevention: Water Management Insights with Dr. Abe Cullom
Scaling UP! H2O
A water management plan protects people only when the facility uses it to guide decisions. Dr. Abe Cullom, Director of Water Safety & Management at Pace Analytical, joins Trace Blackmore, CWT, to examine why Legionella programs break down—and how testing, communication, and consistent implementation can strengthen them. Implementation Is the Bottleneck Five decades after Legionella was identified, researchers understand much more about the organism, its ecology, the conditions that support its growth, and the interventions available to control it. However, Dr....

486 Meter Optimization: Air in the water with Anthony Giudice
Scaling UP! H2O
Water meters register the volume passing through them, but what happens when that volume contains both water and entrained air? Anthony Giudice, president of AquaFlow, explains how turbulent flow can influence meter readings and how AquaFlow’s calibrated valve is designed to help meters reflect what he describes as true water consumption.

Water meters register the volume passing through them, but what happens when that volume contains both water and entrained air? Anthony Giudice, president of AquaFlow, explains how turbulent flow can influence meter readings and how AquaFlow’s calibrated valve is designed to help meters reflect what he describes as true water consumption.
Why Flow Conditions Matter at the Meter
Anthony connects entrained air to the pressure required to move municipal water and the turbulence created as water travels through piping, changes direction, and encounters shifting demand. Because a conventional meter cannot distinguish between water and air within that volume, he says the resulting air-water mixture can contribute to overreading.
The valve addresses the condition from the customer’s side of the property. Installed immediately after the meter, it creates a slight backpressure intended to establish laminar flow upstream while compressing the entrained air rather than removing it from the system.
Calibration, Placement, and System Conditions
Each valve is calibrated for its specific meter and operating environment. Anthony explains why valves cannot simply be exchanged between meters of the same size and describes a dual-spring design that responds to changing pressure throughout the day.
Available sizes range from three-quarter inch to 32 inches, supporting applications from residential service to power plants, data centers, manufacturing facilities, and cooling tower systems. Trace and Anthony also examine an important secondary-metering question: where should a valve be installed when cooling tower makeup and bleed meters affect water and sewer billing credits?
The answer depends on the measurement objective. Teams must first identify which meter they want to optimize and how any downstream reading affects utility calculations or sewer credits.
Measuring Results Beyond the Utility Bill
A lower invoice alone does not prove that a valve is performing. Facility activity may change substantially from one billing period to another.
Anthony recommends a measurement and verification reconciliation using 12 clean pre-installation months, the installation month, and at least three clean post-installation months. Consumption should then be normalized against an operating unit such as cars washed, hotel guests, or stadium attendance.
A car wash example demonstrates the distinction. Recorded consumption changed from 16.03 gallons per car before installation to 13.13 gallons per car afterward. That per-unit comparison provided a clearer performance indicator than the total bill, which could rise or fall with the number of vehicles served.
Careful meter selection, operating data, and normalized analysis help water professionals evaluate this technology without confusing reduced recorded consumption with changes in production or occupancy.

Quotes
“Meters, unfortunately, people don’t like to hear this, but they’re designed to register volume. Volume is anything that passes underneath the meter.”
“Each one is specific to that meter. You can’t just start, even if they’re the same size, you can’t just start switching them around.”
“We’re not compressing water. We’re compressing the entrained air in the water.”
“It was 16.03 gallons of air and water. When the valve was installed, it forces a true water consumption reading of 13.13 gallons.”

Words of Water with James McDonald
Today's definition is a measure of the tendency of a volatile substance, such as a neutralizing amine, to remain in the steam phase. It is defined as the ratio of the concentration of the substance in the steam phase to its concentration in the liquid phase. Can you guess the word or phrase?
