S&L Assists Food Processor with Treatment Plant Solution

The macadamia nut is indeed favored by many as a high quality nut, evidenced by its extensive use in desserts or simply as a premium stand-alone snack. One of the world’s leading producers of these delicious nuts produces more than 15 million pounds each year from its Hawaii processing plant.

Producing the nuts is a rather meticulous process that involves multiple steps, including collection, high-strength cracking, cleaning and dehydration. High-strength wastewater is primarily generated from the nut-cleaning stage, in this case more than 10,000 gallons per day (38 CMD) with 2,500 mg/L BOD and suspended solids greater than 1,000 mg/L resulting from shell residuals collected in the cleaning process.

To meet permit guidelines, the producer in 2009 selected a Smith & Loveless TITAN MBR™. The 31’ X 12’ (9.4 m x 3.7 m) pre-engineered system, featuring S&L flat-plate membrane technology with a complete, yet compact process design, easily meets the effluent requirements while minimizing precious land use at the processing facility. The unique S&L design begins with a robust and stable process scheme that minimizes daily operation requirements. The system’s flat-plate membranes remain submerged within the aeration zone (a key in reducing plant footprint), and they only require seasonal chemical  leaning for just a few hours. This efficient cleaning cycle can be accomplished while the plant remains in operation, enabling plant resources to remain more focused on producing those tasty nuts.
