Recirculating Aquaculture Systems (RAS) require tailored process designs and specialized equipment configurations to meet the distinct biological and environmental needs of different cultured species. Variations in waste production, oxygen demand, sensitivity to water quality, and behavioral traits necessitate species-specific adaptations in RAS engineering. This article examines these critical differences by analyzing the process flows and core equipment for four key aquaculture taxa: finfish (e.g., salmon and trout), crustaceans (e.g., shrimp), sea cucumbers, and abalones. Each group demands unique solutions in filtration, aeration, and system architecture to optimize productivity while maintaining water quality standards.

Comprehensive guide to UASB reactor design for high-strength wastewater: principles, pretreatment, calculations, system components (3-phase separator, distribution), biogas recovery, and operational parameters. Achieve 70-90% COD removal efficiently.

In the MBBR (Moving Bed Biofilm Reactor) aerobic tank, pH is one of the key environmental factors affecting nitrification. Nitrification is driven by autotrophic nitrifying bacteria (including ammonia-oxidizing bacteria, AOB, and nitrite-oxidizing bacteria, NOB), which are highly sensitive to changes in pH. pH influences the efficiency and stability of nitrification through multiple dimensions.

1. Fluid Dynamics in Moving Bed Biofilm Reactors MBBR technology relies on hydraulic principles: mbbr filter media (fill ratio: 25-70%) are kept in suspension via aeration (aerobic zones) or mechanical mixers (anoxic zones). This creates a "mixed bed bioreact...
