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 […]
How to Choose Wastewater Treatment Mixers?
What are the common types of mixers used in wastewater treatment? 1. Submersible Mixers Mixing Series: This series is suitable for agitating liquids containing suspended solids in municipal/industrial wastewater treatment processes. It typically uses multi-stage motors with a direct-drive structure (low energy consumption and high efficiency, functioning like an energy-saving expert). Impellers are precision-cast or […]
Distinguished Water Solutions Partner Visits Sperta
On April 23rd, 2025, representatives from a leading water solutions enterprise visited Sperta in Shanghai, China. With 16 years of expertise in membrane technology R&D, Sperta demonstrated the innovative design and reliability of its new-generation antifouling PVDF-MBR membrane modules. Following technical discussions, both parties signed a long-term supply agreement to collaborate on municipal wastewater treatment […]
The ORP Guide: Why, What, and How in Anoxic Tanks
ORP (Oxidation-Reduction Potential) is a vital monitoring parameter for wastewater treatment in anoxic tanks. Measured in millivolts (mV), it reveals a real-time balance between oxidizing and reducing agents in the system. By maintaining optimal ORP values, operators can effectively enhance biological nitrogen removal efficiency, stabilize treatment performance, and meet environmental compliance standards—all critical for optimizing […]
