The uptake of dissolved nutrients by microalgae is the primary way to remove nitrogen in aquaculture systems. Many authors have studied the use of microalgae to treat wastewater from aquaculture. However, excessive microalgae accumulation may cause high levels of organic matter and suspended solids in the final effluent. Thus, an efficient way to remove excess algae is needed in wastewater treatment. In this study, the potential of the filamentous cyanobacterium,
Ambar Amaral is a family owned business in Santa Fé do Sul, Brazil. Making use of the enormous fresh water potential in Brazil, the family decided to invest in tilapia farming.Today, the Ambar Amaral Group market its own consumer brand under the name Brazilian Fish, selling fresh and frozen Tilapia filets, and even ready-to-eat microwave meals.1,195 km2The Ambar Amaral Group’s Tilapia farms stretch out over 1.195 km2 of water surface, making the company the third biggest producer in Brazil.20+ retail...
Seeing the rapid surge of tilapia farming in the Santa Fé do Sul region in Brazil, Emerson Esteves recognized the need to produce high quality PL to support business activity in the area. He founded Peixe Vivo: a medium-scale hatchery specialized in tilapia.A close eye for detail, controlled hygiene and temperature conditions and a thorough perfection of feeding technologies led him to obtain an impressive 99% survival rate and a solid reputation in the local market.99% survivalApplying the same meticulous...
Water and nutrient savings can be established by coupling water streams between interacting processes. Wastewater from production processes contains nutrients like nitrogen (N), which can and should be recycled in order to meet future regulatory discharge demands. Optimisation of interacting water systems is a complex task. An effective way of understanding, analysing and optimising such systems is by applying mathematical models. The present modelling work aims at supporting the design of a nearly emission-free...
Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to deeper understand their impact on transport of substances and to improve the watershed management. In particular, nutrient...
