Immersed MBR membranes

Ultrafiltration is a process that uses organic polymer membranes to filter particles by size and is typically used to separate or remove bacteria and macromolecules with molecular weights greater than approximately 300,000 daltons from wastewater in both municipal and industrial applications.

UF pressurized membranes

TT is the English acronym for Tertiary Treatement, i.e. a process whose ultrafiltration has the aim of removing bacteria and macromolecules downstream of a secondary sedimentation process. The application with pressurized membranes is usually used to obtain a very high quality permeate in anticipation of its reuse in agriculture, or for its return within industrial production cycles. The pressurized ZeeWeed® membranes are made of two different materials depending on the type of applications required, PVDF or PES.

UF submerged membranes

Another possible application of ZeeWeed organic polymeric membranes is in the production of drinking water from sea water/rivers/lakes etc., where a high level of control over the quality of the permeate intended for human consumption is necessary: ultrafiltration in this case it carries out a fundamental refinement treatment to remove suspended solids and bacteria before sending the water to the final polishing stage (activated carbon/UV) and then to the distribution network or RO sections (Reverse Osmosis).

Reverse osmosis membranes

Reverse osmosis is a water purification process (reduction of salt content) which is achieved by reversing the direction of the osmotic flow, therefore forcing the water from the more concentrated solution to flow through the semi-permeable membrane towards the less concerted solution.

Process optimization and energy saving solutions

Creapro® is an advanced control platform that manages and optimizes the treatment stages of a purification plant in real time based on a combination of mathematical models and advanced control logic that guarantee more effective system monitoring and directly measurable energy savings.

MABR Aeration membranes

The English acronym MABR “Membrane Aerated Biological Reactor” defines a particular application of gas permeable membranes in the treatment of municipal wastewater based on the ability of organic biofilms to develop and grow adhering to the membranes which act at the same time as a support and device supply of the oxygen necessary for their reproduction.

Biomedia applications for MBBR and IFAS

Biomass technology adhered to mobile supports exploits the ability of the colonies of microorganisms that develop in the biological process to form a biofilm that grow adhering to the surface of special elements made of plastic material which are dispersed throughout the process volume.

Percolation Towers with attached biomass

The technology takes its name from the gills of fish (gill in English means gill) because, as happens in many aquatic animals in which thanks to them, oxygen is transferred from the water to the fish’s organism, in the case of Biogill, the gill represented by a lamellar surface of nanomaterials acts as an exchange element capable of amplifying the transfer of oxygen from the atmosphere to the microorganisms responsible for the purification process.

Electrooxidation devices

The technology is essentially aimed at tertiary industrial applications, i.e. stages of refinement of already pre-treated wastewater in which the further removal of specific pollutants, or emerging pollutants, which otherwise cannot be eliminated such as antibiotics, benzodiazepines, pesticides, refractory COD and colour, is required.
