INDUSTRIAL WATER AND WASTEWATER TREATMENT
Rethinking Aeration: Demand-Based DO Control And Energy Optimization
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

Utilizing Thermal Mass Flow Meters To Optimize Thermal Oxidizer Performance And Reduce HAP/VOC Emissions
Many processes in the oil/gas refining, specialty chemical production, solvents, paint, coatings and photoelectric industries generate hazardous air pollutants (HAPs) and volatile organic chemicals (VOCs), which need to be removed from waste, flue and tail gases before emission into the environment to meet clean air regulations around the world. In addition to removing problematic greenhouse gases, emphasis is placed on eliminating toxins that can be harmful to industrial workers and the environment.

Overcoming Water Scarcity Challenges On Providenciales Island
The residents and industries of Providenciales Island are completely dependent on fresh water produced by a single desalination plant. In 2007, ITT Flowtronex was hired to replace the plant’s overworked pumping system and add a booster pumping station to the distribution system. One of the challenges they faced in designing controls for the system was how to maintain the public water supply while the island’s undersized ground water storage tanks were removed and replaced with a large single tank in the same location, a three to four month process.
