The City of Tampa's Howard F. Curren Wastewater Treatment Plant uses vibration analysis hardware and process controller equipment to protect critical machinery against damage from mechanical failures or environmental changes, ensure survivability and prevent unscheduled downtime and costs. This system uses relays to trigger alarms or shutdowns and is integrated to the main plant's Supervisory Control and Data Acquisition (SCADA) system. Here is a look at how this system was chosen and installed.

Compared to conventional biological wastewater treatment systems, submerged membrane bioreactors (MBR) produce significantly improved effluent quality and have a substantially smaller footprint. Throughout the past decade, MBR systems have been installed in thousands of municipal and industrial wastewater treatment plants for challenging wastewater applications for plants including paper mills, breweries, food processors, chemical plants and textile manufacturers.

A recent call to troubleshoot a horizontally-split multistage pump reminded me of my good old days working for an OEM. When an OEM de-stages a standard design, an important engineering step is properly sizing the center bushing. Unfortunately, when requested to de-stage a multistage pump, some repair shops do only that. They take one (or several, depending on the target flow/head/power conditions) of the stages off, replace it with a straight-through bushing and leave all the remaining internal components intact.

There are two largely accepted facts about mining: 1) A mine's landscape is dynamic, and 2) Within that landscape, water is a mine's worst enemy. Navigating a mine's landscape with pumps designed to move and/or remove water has long been the challenge of mine operators.

Mercator Mineral Ltd. officials needed to expand and streamline a freshwater supply system for an expansion of Mineral Park Mine, its wholly owned open-pit copper and molybdenum mine near Kingman, Ariz. For this water supply system, they needed an energy-efficient solution that integrated key controls within a network of multiple pump stations.
Due to high specific gravity, viscosity and particle size of mining materials, centrifugal pumps are continuously challenged in mining applications. New pump technology was created to efficiently move mining materials with less downtime.

This is the fourth part of a series based on Optimizing Pumping Systems: A Guide to Improved Energy Efficiency, Reliability, and Profitability, written by pump systems experts. This new guidebook continues the mission of Pump Systems MatterTM and the Hydraulic Institute to advance knowledge on pumping systems.
Born in the 3rd century BC, pumps are one of the most important mechanical devices in all industrial applications. Sustaining their importance in a mature market characterized by steady growth and slow technology change, the key competitive factors are price, delivery period, brand reputation, and service. In spite of traveling over time across several verticals of applications, opportunity strikes this centuries-old industry.
