The cost of high solids in your wastewater treatment plant

  Conventional activated sludge wastewater treatment plants (WWTP) operate with solids (mixed liquor suspended solids ­– MLSS) concentrations ranging from approximately 1500 to 5000 mg/L. In membrane bioreactors (MBRs), typical MLSS concentrations are even higher (10,000 to 12,000 mg/L). A higher concentration can be advantageous as they allow for smaller aeration tanks while performing the… Read More

Drinking Water – A Global Concern

  Issues related to drinking water and municipal water systems are all over the news these days. In North America, the troubles that Flint, Michigan has faced with its water supply and distribution system have been in the headlines for a number of years now. Government officials continue to struggle to replace aging infrastructure and… Read More

Enhanced Biological Phosphorus Removal – Who’s doing the work?

  Enhanced biological phosphorus removal (EBPR) was first documented in the early 1970’s. Traditionally it has been understood that EBPR requires a first stage anaerobic zone that is free of nitrate and nitrite. In the anaerobic zone, phosphorus accumulating organisms (PAO) utilize energy from stored polyphosphate to assimilate volatile fatty acids (VFAs) and produce polyhydroxybutyrate… Read More

Water industry events: mark your calendar

  Across the globe, people are gathering to talk about water. Whether the topic is effluent management, potable water or ocean conservation, there is an organization and event designed to allow individuals to come together to share their challenges and solutions. Here at LuminUltra, we recently participated in the Water Environment Federation’s Annual Technical Exhibition… Read More

Top 3 questions from the latest WQTC

  AWWA’s WQTC is a favourite event among many water quality professionals (us included) and after another excellent conference, we wanted to answer the top 3 questions we were asked at the conference in Portland, Oregon. 1. What does your test measure? Can it test for specific species? Our tests measure the ATP concentration in… Read More

Thank You, Amazing Vietnam!

  In November, as part of my role in developing the LuminUltra business in the Asia Pacific Region, I ventured off to Vietnam alongside nearly two dozen other Australian businesses. We were part of the Australian delegation (largest ever) for the Vietwater 2017 exhibition in Ho Chi Minh City. The delegation was organised by the… Read More

How often should I measure ATP in my wastewater treatment plant?

  LuminUltra’s 2nd Generation ATP has many potential uses within a wastewater treatment plant (WWTP), including: diagnosing acute and chronic toxicity, optimizing solids concentrations in the aeration tank, optimizing dissolved oxygen setpoints and identifying sludge bulking events. How often you should measure ATP depends on the quantity of data you’ve collected, the operational performance of… Read More
