Aquaculture/Marine Fisheries Process Wastewater

摘要

Wastewater samples from alligator production/processing facilities, and fromcrawfish, catfish and crab processing plants were collected and analyzed to determine quality and quantity characteristics which would help producers/processors prepare permit applications and/or reduce costs of managing wastewater and help the Louisiana Department of Environmental Quality establish wastewater discharge permits, consultants design treatment systems. Little data was previously available to characterize alligator or crawfish wastewater and for small plants processing other species. Results from alligator wastewater analysis indicated considerable variation between facilities and within facilities depending on time of sample collection. Crawfish processing wastewater varies with the process being sampled and time of day of sampling. Boiling process generates strongest effluent. Catfish and crab samples varied somewhat from published data. Technology transfer programs with Fisheries Agents, regulatory agency staff and producers/processors have been instrumental in increasing understanding of problems and probable solutions.
