Wastewater Case Studies and Whitepapers

1. Filtering Out Failures: A Productive Conversion Experience For A Steel Mill 10/6/2020

   Water filtration in steel manufacturing should be one of those things that mill owners never have to worry about. But when filter systems fail to perform as expected, it’s time to invest in a smarter design. That was the situation at a midwestern steel mill that embarked on a major, eight-year conversion of its water filtration infrastructure.

2. Tackling Rising Energy Costs 6/21/2023

   Within the water treatment industry, aeration processes consume the most energy. However, costs for electricity are continuing to rise, even for large customers that are accustomed to negotiating lower than average prices.

3. New And Innovative Rare Earth Technology For Low-Level Phosphorus Removal 9/18/2014

   With environmental regulations continuing to restrict the discharge of phosphorus from wastewater treatment facilities, traditional methods of phosphorus removal are proving inadequate.

4. Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings 9/13/2018

   The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

5. Lagoon-Based Extended Aeration System Meets Effluent Requirement For Year-Round Ammonia Reduction 3/3/2011

6. Is It Time To Reassess Your Industrial Membrane Filtration Infrastructure? 9/21/2021

   With infrastructure being such a hot topic these days, it is only fitting that industrial water treatment professionals take a second look at their own infrastructure. Here are some areas where new pressures from the impacts of climate change, population growth, or government regulations can benefit from improved filtration membrane technology approaches.

7. How Ultrasonic Sensor Technology Can Increase Processing Plant Efficiency 5/14/2019

   In today’s competitive business environment, which focuses on increased throughput, economies of scale and a healthy bottom line, accurate and reliable measurement is a key component. Monitoring production processes by installing a wide range of sensors including flow, level, temperature, and pressure is common and crucial to be competitive. Although there are many reasons why plant managers decide to install monitoring devices in their process, environmental and regulatory reasons dominate one side of the spectrum, whereas quality, process control and monitoring govern the other.

8. Using Supersaturated Dissolved Oxygen To Reduce Costs And Increase Treatment Capacity 1/10/2023

   Supersaturated dissolved oxygen (SDOX®) can cut aeration-related energy costs in half for a range of applications, including activated sludge systems, oxidation ditches, odor control in collection systems, and more.

9. How UF Membrane Fiber Strength Impacts Reuse Success 7/17/2019

   Ultrafiltration (UF) has been proven a key in wastewater reuse, but operators have struggled to keep up with repairs or having to replace older hollow-fiber membranes. Recent advancements in manufacturing have produced more durable membranes that accomplish the task at a lower cost.

10. Slashing Recycled Ammonia Loads From Dewatering Sidestreams 12/9/2019

    Recycling is generally considered a positive thing, except when the sidestream discharge from the dewatering of anaerobic digested sludge can recycle up to 40 percent of the total nitrogen or ammonia load in the original flow back to the head of the wastewater treatment stream. Deammonification technology using anaerobic ammonium oxidation/anammox bacteria offers a cost-effective way to break that vicious cycle and meet regulatory discharge limits.
