An industrial client, located in Brazil, which produces parts for automotive industry. The company used to use a traditional physical-chemical WWTP wastewater treatment process, which was based on standard coagulation-flocculation. Yet, this system could not solve efficiently oil removal and metal precipitation issues. Additionally, it presented high operational costs and low efficiency levels. In order to solve such problems, VentilAQUA proposed the use of an AOP electrocoagulation and electro-oxidation which were easily added to company’s existing plant. All in all, our intervention allowed this Brazilian company to reduce costs, increase compliance, reuse water, and decrease sludge.

One of the major dairy Portuguese companies entrusted to VentilAQUA the development of a complete solution for their waste water treatment. Keeping in mind the best systems to treat waters coming from milk, butter, and cream processing, VentilAQUA suggested the use of a batch biological oxidation process or a SBR process (sequence batch reactor), which in this case ended up using three SBR reactors, all under VentilAQUA’s SmartSBR system, to treat together about 600m3 daily. At the end of the day, this technology allows our client to partially recover water that may be reused in irrigation and current washing activities. Waters from the cheese production site are pre-treated on a DAF system, prior to the common biological oxidation step. The sludge produced on the oxidation process is dehydrated by a centrifuge unit.
