The Chiquita WRF plant was looking to improve the performance of their existing gravity thickeners better than the 2.3% DS that they were previously achieving. In their search for a solution they discovered the S-Disc technology from Huber Technology.

Like so much of America’s infrastructure, our wastewater infrastructure is aging and inadequate. Like our highways and bridges, our wastewater infrastructure needs improvement. How do we solve this problem?

Learn how Hydra-Stop’s insertion valve provided new control points to mitigate future disruptions during a service line emergency.

A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

The plant manufactures touch panel and polarizer which are materials for LCD assemblies. Since the manufacturing process is a semiconductor process, the wastewater contains large quantities of organic solvent from developers, strippers and rinse liquid waste. By KLa Systems

After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.

To comply with new EPA rules and handle additional flow, the City of St. Charles Missouri WWTP required a capacity increase, and the landlocked plant needed a solution that would fit within its existing footprint. Brush aerators and boat clarifiers were replaced with 12 VLR-mounted disc aerators to fulfill the oxygen requirement while allowing for the treatment of higher organic loading. The solution provided increased nutrient-removal capacity and improved efficiency without increasing tank volume.

Confronted by everyday operating challenges, many decision-makers at drinking water and wastewater organizations do not always have all the time they would like to develop big-picture strategies and tactics for current and long-term concerns. Fortunately, multiple dedicated water-advocacy organizations do. Here are seven areas where water strategists, decision-makers, and other leaders can benefit from those valuable insights.

Today, the drive toward more advanced technology is stronger than ever, as we expand our use of predictive modeling and data-centric solutions.

Planning how to address environment-impacting, water-infrastructure challenges — reducing stormwater runoff pollution, reducing sewer overflows, and protecting rivers and streams that serve as drinking water supplies for downstream towns — can be an intimidating task. A recent report from the Environment America Research & Policy Center cites many examples that can serve as beacons for municipalities large and small.

In wastewater treatment, phosphorus testing can quickly become confusing. For example, there are three different tests. So, which test was performed? Test results can be displayed in two different forms. So, which form was utilized? Tests can measure both particulate and dissolved phosphorus. So, was the sample filtered?

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

We arm farmers with mission-critical water data to help enhance crop yield and taste. KETOS delivers valuable insights for fluctuations in deficiency and toxicity.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
