Optimizing Reuse of High Load Wastewater
Aquaculture processing plant
An aquaculture company was seeking to treat high nutrient wastewater from their fish processing operations. They needed to meet a discharge limit as well as create a value added waste prod-uct from the concentrate. The critical parameters were to reduce the COD below 500 mg/L and to achieve a >5X concentration of phosphorus in the waste. This concentrate was evaluated by prospective customers in the fertilizer market.
To meet the discharge limit at a permeability ca-pable of scaling up to large treatment volumes, Cerahelix used the NanoHelix. We installed a pilot unit cross flow filtration system containing our ce-ramic NanoHelix membranes.
|Wastewater flow||100,000 GPD|
|Influent COD range||3000—4000 ppm|
