Ovivoisoneoftheleadingsuppliersof industrial water treatment processes, and we are consolidating our position through resolute development andconstant striving towards high quality. Ourfocusisonwatertreatmenttechnology, ranging from fresh water treatment and process water treatment to the cleaning of effluents.

Ovivohaswideandlong-termexperienceandexpertiseindifferent types of water treatment methods.Oneofourkeytechnologiesfor biological water treatment is an advanced,high-loadedbiologicaltreatment system, called the Ovivo®MBBR(MovingBedBiofilmReactor).

Main FeaturesTheOvivoMBBRisabiological treatment process for municipal and industrial applications. The core of the Ovivo MBBRprocessisanadvanced biofilm carrier element, combinedwith optimizedEWTaerationandmixing,usingcontinuous process control.

TheOvivoprocesscanhave one or several stages, in seriesorparallel.Anexistingprocess can be upgraded with OvivoMBBRtofunctionasamodernOvivoBASprocess. This is called OvivoRebuildprocess.

There are several methods used to clarify the effluent treated with OvivoMBBR.Theseinclude,among others, microflotation, conventional sedimentation, and lamella sedimentation.

Part of the sludge can be recycled backtotheOvivo MBBRprocess,improving the running and stability of the process. The rest of the sludge is dewatered further.

Todayallindustrialplantsaretakingfull responsibility for the way process waters affect production and the environment.Freshwatertakenfromnatureiscleaned,utilizedand recycled carefully within the processes. When returned to nature, the water has to meet the highest possible standards. These targets can be achieved by Ovivo MBBRbasedbiologicaltreatment solutions.

Enhanced Ovivo® MBBR AerationBiologicaloxygenneedandmixingoftheprocessareperformed by an improved bottom aeration system. The OvivoMBBRaerationsystemcovers the entire bottom area, guaranteeing an efficient use of capacity.

There are two efficient alternatives for the aeration: Plastic Diffuser Aeration and PerforatedSteelPipeAeration.The aeration system is tailor made for each application.

Aeration systems can be built intobothnewandexistingbasins. The Ovivo aeration is anon-cloggingandpracticallyservice free system. High prefabrication degree provides excellentqualityandsignificantly shortens the onsite installation time.
