The residents of Orlando and nearby communities are more likely to see lightning strike than have their toilets run dry. Extensive high-tech upgrades at Orlando's three advanced wastewater treatment plants, including new automation and control systems, have helped city staff process more sewage and gray water effectively and reliably.

Pressure gauges are a versatile way to monitor pump operation.

Pulsation and water hammer can be limited with proper forethought and equipment.

Choosing the right differential pressure flow meter for an application can be challenging. This article outlines the considerations and trade-offs in selecting the optimal technology.

Water system operators know the challenges of keeping municipal drinking water consistently and safely chlorinated. Increased safety concerns regarding common disinfectants and mandated chlorine residual targets make maintaining large or small water systems difficult.

One electrical equipment specialist is relying on a cleaning system to ensure that a variety of stamped and turned parts are thoroughly degreased at their production facility.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

Changing traditional industry ways of thinking can help usher in the plant of the future.

In only a couple of years, the focus on energy efficiency has gone from blurred to steely-eyed. Green business practice is now a necessity, and organizations must find the best way to transition to this new reality. There are many opinions and approaches on "how we get there," and each one will have its own merits. A journey of a thousand miles starts with a single step, and making the right steps in the beginning will hasten the achievement of energy efficient goals.

Holistic pump system designs optimize system efficiency and life cycle performance.

A variable frequency drive (VFD) can be a valuable asset in reducing the life cycle costs in certain types of pumping applications. The traditional method of motor control in pumping applications is a low cost mechanical starter, which is essentially a large switch with a built-in motor protection device known as a thermal overload relay. A conscious decision to reduce upfront costs by using a mechanical starter may result in higher energy consumption, excessive component wear and poor power quality.

Although the use of transmitters in pressure measurement is growing, mechanical pressure gauges are still used on most systems as local pressure display to back up electrical readings. The selection and installation of these gauges can be difficult in certain locations. Harsh conditions that can require special consideration include vibration, pressure pulsation, overpressure, corrosive media and extreme process and ambient temperatures. This article is designed to address harsh conditions with best practice recommendations to extend gauge life and provide for the safest installation possible.

Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

An 1,800 MW power station in the Midwest experienced constant trouble with four of its four-stage boiler feed pumps, which were driven by steam turbines and operated at variable speed to meet the required plant load.

Increased efficiency, higher air handling and fast, automatic priming are provided with new technology.

Qualified, quality solution providers can resolve many aftermarket problems.

Data and life cycle management technology helps refineries maintain equipment and reduce the total cost of ownership.

Mechanical pressure gauges, which require no external power, provide an affordable and reliable source of accurate pressure measurement. Using the criteria below can help maximize gauge life.

While scheduled downtime is different from unscheduled, both can take away from a company.

Many items must be considered when designing pump station control systems with power requirements, level control method and control panel location often among the most important.

Most VFD systems use some form of closed-loop feedback to avoid surging, excessive noise, and in extreme cases, vibration. A reliable encoder signal is one method that minimizes speed variance and helps eliminate these unwanted effects. Here's how it works.
