IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

TREATMENT OF SEAFOOD PROCESSING WASTEWATER USING A MOVING BED BIOFILM REACTOR (MBBR)
Author : NGUYEN THI NHU NGOC, LE MINH TAI & TO THI HIEN
The continuously operated laboratory scale moving bed biofilm reactor (MBBR) with Kaldnes K3 carrier was proposed for treatment seafood processing wastewater. The reactor was operated at 6 organic loading rates 1, 1.5, 2, 2.5, 3; 4 and 5 kgCOD/m3.day with the constant hydraulic retention time 8 h. The results showed that the suitable organic loading rate was 4 kgCOD/m3.day. The average results of COD, NH4+-N, Total Kjeldahl Nitrogen (TKN) and Total Phosphorus (TP) removal efficiencies were 95.9%, 89.6%, 76.5% and 66.8%, respectively. The effluent met Vietnam Technical Regulation on the effluent of aquatic products processing industry QCVN 11:2008/BTNMT, column B. The study has shown that MBBR can be operated at the high organic loading rate compare to other aerobic processes and it is feasible for simultaneous organic compounds and nutrient removal from seafood processing wastewater.
