How to Calculate MBR Membrane Surface Area
When designing MBR systems, membrane area is a critical parameter. It directly affects system capacity, operational safety margins, and membrane service life. For engineers and project decision-makers, understanding how membrane area is calculated is essential to making informed choices in membrane selection, system sizing, and operational management.This article explains the principles of membrane area calculation […]
What Is Bio-Cord Media in Wastewater Treatment?
Bio-Cord media is a rope-type biological media that increases attached biomass and improves treatment stability without expanding tank volume. Bio-Cord media uses polymer fibers woven into multi-strand ropes. We install it by either hanging it or mounting it inside biological reactors. Water flow and aeration cause slight movement, which helps microorganisms attach quickly and form […]
SPERTA Participates in Aquatech China 2025
Aquatech China 2025 was held from November 3–5 at the Shanghai New International Expo Centre. As a leading water technology trade show, it covers drinking water, industrial water, wastewater, and sludge treatment, smart water solutions, and water resource management. Under the theme “Focusing on the Water Industry, Covering the Full Spectrum,”Aquatech served as a key […]
What is the Difference between Organic and Inorganic Wastewater?
In wastewater treatment, it’s important to understand the difference between organic and inorganic wastewater. They differ greatly in composition, biodegradability, and treatment approach. Among various technologies, MBR (Membrane Bioreactor) systems—especially those using SPERTA membranes — perform exceptionally well in treating organic wastewater, providing efficient organics removal and clear, stable effluent. What is Organic Wastewater? Organic […]
MBR Membrane O-rings: Types, Materials, and Selection Guide
In the MBR (Membrane Bioreactor) module, the O-ring may seem like a small accessory, but it plays a very important role in maintaining long-term system stability. Different O-ring materials may perform differently in temperature resistance, chemical stability, and aging resistance. Choosing the right O-ring not only prevents leakage but also extends the membrane module’s lifespan […]
