BRK Recife CFIC
The challenge
The city of Recife is the biggest one in the northeast region of Brazil. This new plant treats part from city’s southern area with flows up to 180 l/s. The extremely small available land demands creativity to fulfill all legal requirements as also as complying with odor and nuisance to the surrounding neighbors.
The design
In 2017 Biowater Technology AS through local partner Memphis Empreendimento proposed CFIC® as the solution for the wastewater treatment. This technology was chosen over other technologies as Activated Sludge, SBR and MBBR due to its advantages including compactness, low TSS in the effluent (no need for a separate separation stage), ease of operation, and low operational cost. The CFIC® technology offers 50% reduction in the energy consumption compared with conventional MBBR which, together with the reduction in the carbon footprint, provides cost reductions to the whole life of the plant.
Achievements
Since the plant operation has commenced the CFIC® plant in Recife is only run in wash mode 14 hours per week. The removal efficiency of the organic loading since start up has been equally a promising. Incoming COD (chemical oxygen demand) is 500 mg/l and effluent presents less than 90 mg/l, a removal of more than 80 % and well within the discharge limits for the project. The TSS (Total suspended solids) from the plant is less than 25 mg/l. The BOD (biological oxygen demand) in the effluent is also well under the maximum regulatory level (< 30 mg/L), with an average in the range of 15-20 mg/L.
