Precipitant Savings Through Optimized Phosphate Elimination With Integrated Predictive Diagnostics
4/18/2017
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.

North Las Vegas Puts Advanced Wastewater Treatment To Work
12/13/2021
The North Las Vegas Water Reclamation Facility treats an average of 17 million gallons a day (MGD) of wastewater through an advanced nutrient removal process with subsequent membrane filtration. The utility’s process control enables treatment effluent exceeding typical environmental standards and allows discharge to Lake Meade, where it subsequently is withdrawn and fully treated by other facilities for drinking water distribution.

City Saves Money And Energy With Real-Time Control System
12/12/2013
Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.
