Dai Dai Thanh Seafood Wastewater Treatment System
Collection tank: Collect all the wastewater on the channel leading to the treatment system.
Equalization tank: Stabilize flow, pollutant concentration, pH. Preliminary ventilation to avoid anaerobic decomposition causing odors.
DAF flotation tank: Separation of fat mixed in wastewater in two forms of “suspension and suspended sediment” by the DAF pneumatic method to float suspended particles to create surface grease. Surface degreasing by a degreaser reduces the contaminant concentration eligible for the biological treatment stage.
ANAES tank cluster: Wastewater after flotation is put into Anaes biological treatment tank cluster.
This is a system of 3 tanks, these tanks are connected by an opening between the tank walls. Two tanks 1 and 3 simultaneously perform 2 functions: both a biological reaction tank and a settling tank. Wastewater is put into each tank depending on the cycle.
Coarse filter device: The water after passing through the Anaes tank cluster has many components such as: eggs, suspended sediment. Therefore, the water needs to go through the coarse filter to remove these suspended substances, making the water clear and meeting the discharge standards.
Disinfection tank: Contact with Chlorine to completely destroy Coliforms and other disease-causing germs, the treated water meets environmental standards and is discharged into the receiving source.
