The PVS Primary Wastewater Treatment plant has been developed, in order to considerably reduce influent loads by applying micro belt filtration. This innovation of micro belt filtration as a pre-treatment step ensures a space-saving and effective replacement of conventional primary sedimentation tanks. Furthermore, Primary Wastewater Treatment plants in coastal areas in the form of a microfiltration step are a reasonable, quick and economic solution, in order to reduce the degree of pollution of untreated wastewater before feeding a subsequent plant, since even finest particles (colloids) can be separated. In addition to that, this form of pre-treatment (in the form of a primary wastewater treatment plant) is an ideal requirement for a subsequently installed, biological Wastewater Treatment plant.

PVS VOPROM SBR plants are designed for extremely variable inlet loads. They operate using an advances form of SBR (Sequencing Batch Reactor) process which has been further developed by PVS. The PVS-VOPROM-reactor plant consist of one or more PE-tanks. The volume and quantity of tanks depends on the plant treatment requirements.

This plant concept is simple and effective and is designed to act as a first equipment, as well as a reequipment as a 3-compartment plant, without complexity

The above listed separation technologies differ from each other via pressurized and non-pressurized filtration. Solid matter separation via a micro-filter belt is a non pressurized system which functions using gravitational flow procedures. This process is mainly used by us for the filtration of particles. Membrane technology such as ultra or nano filtration and reverse osmosis are pressurized membrane technologies which we use for the removal of solid content from water (such as bacteria, viruses, colloids, up to dissolved salts and ionic metals).

DAF (Dissolved Air Flotation) & DOF (Dissolved Ozone Flotation) Plants: This process technology is based on the pressure released flotation principle and is mainly applied in case of separation of tiny particles in liquids. The difference between DAF and DOF plants is that DOF plants not only feed oxygen (O2), but additional ozone (O3) as well in form of fine bubbles (micro bubbles) into the liquids. By creating a bubble haze in the liquid (lactic appearance), not only sufficient O2 and O3 is kept in the liquid, but also the transfer process of gaseous into liquid (dissolved) aggregate is being accelerated. Thus the efficiency of the separation and degradation process is increased.

PVS Ozone Plants were designed for a more effective deactivation of microorganisms, in order to achieve a reduction of impurities and pollutants in the water.

This is a recycling concept in which mixed household wastes made up of organic and inorganic fractions must be sorted to recover potentially recyclable fragments. First the organic material is removed by sections of drum screens and the inorganic material is either mechanically or manually separated (depending on plant design) in a sorting station and sent further for specific material separation.
