Water & Wastewater Asia Sep/Oct 2018

Water & Wastewater Asia • September / October 2018 24 | FROM THE GROUND Surpassing requirements MICRODYN BIO-CEL ® -MCP MBR was chosen by a tuna cannery in Mexico to comply with the environmental regulations in Mexico. The results…. Astounding. L ocated in Mazatlán, Mexico, a tuna cannery needed to update their wastewater treatment plant (WWTP) to comply with new regulations and reuse water at the plant. The tuna cannery needed to treat 1150 m 3 /day (304,000 GPD) of wastewater from its tuna processing, and its waste stream has an exceptionally high total nitrogen (TN), total phosphorus (TP) as well as higher organics (COD/BOD) concentrations. Hence, MICRODYN BIO-CEL ® -MCP MBR process was chosen due to its small footprint and low chemical costs. Table 1: Plant BIO-CEL ® MBR operational parameters USING MICRODYN BIO-CEL ® Ten MICRODYN BIO-CEL ® 400 membrane modules were installed at the plant. Unit operations for the WWTP are as followed (see Table 1 for operational parameters): • Dissolved Air Flotation (DAF) treatment • Equalisation tank • One mm Rotating mechanical screen • One Anoxic basin • One Aeration basin (Two dissolved oxygen zones) • Two Filtration basins • Tertiary treatment Table 2: water quality from the different unit operations at the WWTP A tuna cannery in Mexico needed to update their wastewater treatment plant to comply with new regulations
