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),... Read More
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... Read More
A Canadian paper manufacturer utilized LuminUltra’s wastewater test kits for one year and used the data to identify several opportunities for process improvement. Their findings are promising—in addition to... Read More
Establishing a routine monitoring plan for ATP will ensure that you’re able to take preventative action to reduce risk. Learn how here.... Read More
What’s inside: Over the course of a 1.5-month field experiment at a Canadian starch mill wastewater treatment process, LuminUltra Technologies demonstrated the use of its patent-pending Total Control ATP... Read More
Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants... Read More
A colleague recently conveyed a conversation he’d had with an operator at a sewage treatment plant. Society tends to have an unfounded stigma of sewage treatment plants, so... Read More
UV treatment only recently became widely adopted in the water and wastewater treatment industries but the benefits of sun exposure for water purification have been acknowledged for thousands... Read More
What is sludge bulking? Sludge bulking is a severe problem that can plague activated sludge wastewater treatment plants (WWTP). It’s been estimated that 60% of activated sludge WWTP... Read More
Biological wastewater can be a be complex testing environment, but also offers the greatest opportunities for cost savings and overall optimization.... Read More
