Membrane bioreactor (MBR) systems are a groundbreaking solution for wastewater treatment, seamlessly blending biological processes with advanced membrane filtration.

Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

Maintaining dissolved oxygen levels by pairing smart controls with multiple blowers is emerging as a desirable method to address airflow requirements. Selecting the proper system and avoiding unnecessary complications are critical to successful implementation.

Last Dollar is a year-round residential community located just outside of Telluride, Colorado. The facility had been reliant on an aging treatment system that was failing quickly and needed immediate replacement to prevent operational fines. The current technology would not meet the new and more stringent effluent requirements in Colorado, so the project had to be completed quickly and within a tight budget. AquaWorks DBO provided the permitting and site engineering support to ensure the project was completed in 8 months from contract award to system operation.

The importance of bacteria in the treatment of raw sewage and water purification is well known. Here, we report on Sewper Rx, a unique mix of bacteria with powerful properties for treating sewage as well as other water cleaning applications.

Solar dryers are fully automated to feed, move, and discharge biosolids cost-effectively. Even climate changes throughout the year are easily monitored and controlled to produce optimal output. Installation is very flexible with options to add components at a later date. Full automation means employees seldom need to enter the greenhouse and are free to use their time elsewhere.

In 2008, AnoxKaldnes Hybas™ designs were completed by Veolia for the upgrade of the Field’s Point Wastewater Treatment Facility to meet new seasonal effluent limits for TN and TIN.

When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

Keeping pace with changing industrial wastewater treatment demands can raise multiple issues of oxygen demand, capital cost, and operating expense, often without the flexibility of taking basins out of service to upgrade to new levels of performance. Fortunately, there are alternatives for delivering more oxygen to treat more water.

In an ideal world, would we not want to eliminate air filters altogether? What keeps us from achieving this is foreign material, detrimental to air, which moves rotating equipment; meanwhile, the process that receives the air sometimes cannot tolerate it.

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

Read an overview and maintenance tips for chain and scraper systems. 

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

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.
