On July 10 2026 Zhejiang University Smart Fishery Research Center visited Small Boss for MBBR biofiltration technical exchange. The two parties reached a preliminary cooperation agreement on joint R and D of high-efficiency intelligent biofiltration systems.
Small Boss operates dual physical and biological laboratories for full chain testing of MBBR media and PVC pellets, ensuring reliable performance in aquaculture and wastewater applications.
As REACH regulations tighten across Europe, PVC compound buyers face growing pressure to source compliant, high-quality materials. In 2025, the EU added six more phthalate-based plasticizers to the SVHC list, making traditional formulations increasingly difficult to use in international markets. This article explores the key challenges procurement managers encounter when sourcing PVC granules and PVC pellets — from uncertain compliance documentation to performance trade-offs when switching to non-phthalate alternatives. It also highlights the importance of supply chain stability amid fluctuating raw material prices and stricter environmental standards. With over 30 years of experience in PVC compound manufacturing, SmallBoss has proactively transitioned to calcium-zinc stabilizers and non-phthalate plasticizers, ensuring full REACH and RoHS compliance. Our vertically integrated production model allows us to offer application-specific customization, consistent batch quality, and reliable lead times for customers across construction, electrical, and automotive industries. Whether you need rigid pipe compounds or flexible formulations, our team of experts — backed by 68 patents in PVC technology — provides technical support and custom sample development to meet your exact requirements. Every shipment comes with verifiable REACH compliance certificates and RoHS test reports. Contact us today for a free compliance consultation and discover how a trusted PVC compound manufacturer can help you navigate the evolving regulatory landscape with confidence.
This article explains how to choose proper MBBR media for wastewater treatment. It lists six key selection criteria: specific surface area based on pollutant load, media shape for different tank zones, suitable density to save energy, high voidage to avoid clogging, durable raw materials, and matched types for municipal or industrial wastewater. It also introduces supplier Small Boss, which provides K1 and K3 series MBBR media with long service life, low energy use and custom solutions. Readers are invited to contact the company for cost-effective products and professional technical support.
This article reveals that biofilm interface oxygen transfer, not bulk water DO, limits MBBR performance in recirculating aquaculture systems. It explains boundary layer resistance and oxygen penetration depth, emphasizing that engineered HDPE MBBR carriers boost nitrification efficiency by improving micro‑scale mass transfer. It ends with a call to contact for professional MBBR media for RAS solutions.
MBBR bio media is favored in RAS for maintaining water quality, addressing ammonia nitrogen accumulation by providing a large surface area for beneficial bacteria to convert ammonia to nitrite and then nitrate. It outperforms conventional biofilter materials with advantages like high surface area, biofilm attachment, shock resistance and self-cleaning. High-quality MBBR media needs proper structure and durability. As RAS scales, it becomes a key, reliable biofiltration solution for aquaculture.
