Aquamar’s tilapia processing facility is located in the Yaguachi County of Ecuador and operates a state of the art effluent water treatment plant (EWTP). The water discharged by the EWTP complies with Ecuadorian regulations on effluent water discharges into natural bodies of water, as well as with international standards like Best Aquaculture Practices (BAP); (See table below). Additionally, the water discharged by the EWTP is used for irrigation of the agricultural land located near the processing plant.

Aquamar’s EWTP includes the following treatment stages: mechanical separation of large solids, mechanical fat trap, mechanical filtration of mid-sized solids, water homogenization, removal of suspended fat and dissolved solids by use of Dissolved Air Flotation (DAF) technology, reduction of Biological Oxygen Demand (BOD) by use of a biological reactor with Attached Growth Airlift (AGAR) technology, and water clarification.

The sludge generated by the EWTP is centrifuged to reduce its moisture content; it is then used as raw material along with by-products obtained from the tilapia process to produce compounded meal in Aquamar’s meal plant. The compounded meal produced by Aquamar is sold to feed manufacturers for the poultry, shrimp, pork and household pet feed industries.

Aquamar expects to diversify the applicability of the sludge generated by the EWTP and utilize it as key material for the production of agricultural compost.  Further treatment of the water effluent will be carried out in order to reuse it for certain applications in the processing plant.

Aquamar continues to faithfully follow their philosophy of continuous innovation and responsible optimization of natural resources and sustainability.

On February 10th and 11th, two of our Ecuadorian farms received a visit from Aaron McNevin of World Wildlife Fund, who coordinated the recently completed Tilapia Aquaculture Dialogue (TAD). The TAD developed global standards designed to minimize the key environmental and social impacts associated with tilapia aquaculture. McNevin traveled to Ecuador to attend the audit of these new standards at our Aquamar and Produmar farms.

These standards are the result of a five-year process that included more than 200 people from the production and commercial sectors, as well as non-government and government organizations.  For more information about the TAD, go to http://www.worldwildlife.org/tilapiastandards to watch a video about the project and read the final standards document.

Our production systems are always looking to adopt new standards as they validate and reinforce the good aquaculture practices that we already employ. From the beginning, we were in support of the TAD.  Alfonso Delfini E., owner of Aquamar Farm, was a founding member of the TAD and has served on the steering committee since its inception.  McNevin said, “Alfonso has been invaluable and has contributed an incredible amount of aquaculture expertise, patience and faith in the process of standards development. Both personally and professionally, I am grateful for his commitment and participation in the TAD.”
