How Does Precision HRT Adjustment Enhance WWTP Bioreactor Efficiency?
In wastewater treatment processes, Hydraulic Retention Time (HRT) is more than just a design parameter—it’s a core factor that directly impacts the effectiveness of biological systems. For MBR (Membrane Bioreactor) systems, properly managing HRT means achieving stable and efficient pollutant removal within a limited space. What Is HRT and How Is It Calculated? HRT refers […]
Excessive Dissolved Oxygen in MBR Systems: Risks and Solutions
The activated sludge system plays a vital role in wastewater treatment, and dissolved oxygen (DO) is one of the most critical factors affecting its performance. With over 16 years of expertise in the water treatment industry and specialized knowledge in MBR processes, we understand that proper DO control ensures optimal treatment efficiency, reduces operational costs, […]
How to Fix Low Dissolved Oxygen in MBR Systems?
Low dissolved oxygen (DO) concentration is a common and critical operational issue in wastewater treatment systems. Insufficient DO affects the regular metabolic activity of microorganisms and often leads to the overgrowth of filamentous bacteria, causing sludge bulking, elevated suspended solids in effluent, and reduced treatment efficiency. Compared to conventional processes, Membrane Bioreactor (MBR) systems offer […]
How Does Strategic DO Control Boost MBR Efficiency?
Membrane Bioreactor (MBR) systems have gained widespread popularity due to their stable effluent quality, compact footprint, and high level of automation in wastewater treatment. However, one key parameter that is often overlooked but determines the efficiency of an MBR system is Dissolved Oxygen (DO). Why Is DO So Important? The MBR process relies on active […]
Does High Chloride Concentration Affect MBR Process Performance?
In industrial wastewater treatment, chloride ion (Cl⁻) concentration fluctuations are a critical factor. As high-chloride wastewater becomes more common in industries such as chemicals, food processing, and textiles, many operators are asking: Does high chloride content affect the stability and efficiency of MBR (Membrane Bioreactor) systems?The answer is yes — excessive chloride levels can significantly […]
Why Does Carbon Overdose Cause Sludge Bulking in MBR Systems?
Carbon sources serve as microorganisms’ “energy drink,” vital in enhancing nitrogen and phosphorus removal in wastewater treatment. However, more is not always better—overdosing carbon can disrupt the balance of activated sludge systems, especially in Membrane Bioreactor (MBR) operations, leading to a significant issue: non-filamentous sludge bulking. So, how can you identify this issue early? What’s […]
