Making The Best Of A Bad O2 Situation
A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O2 to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.

Giving Thanks For Water Advocates' Big-Picture Thinking
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.

Safe, Energy Efficient Disinfection For 45 MGD Combined Sewer WWTP Improves Water Quality
The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.

LATEST INSIGHTS ON WASTEWATER
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
-
Strategic flow monitoring helps wastewater utilities curb overflows, cut costs, and safeguard public health by turning accurate data into proactive action.
-
When seeking bids for a fair comparison, it’s important to evaluate the total cost of ownership.
-
Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.
