A tangential filtration device, particularly for fluid food products, includes a tangential filter arranged essentially vertically and provided with a plurality of filtering membranes having a longitudinal extension and arranged essentially vertically, an inlet for the product to be filtered, an outlet for the retentate and an outlet for the permeate. The inlet for the product to be filtered is disposed at the lower portion of the tangential filter so that the filtering membranes are longitudinally crossed, from the bottom upwards, by the product to be processed. The device further includes a pump, a cleaning apparatus, and a collection area.

The water purification system for flow-coupled installation with a tap water inflow for producing a relatively purified water outflow includes a purification unit having a tap water inlet port for receiving tap water inflow and a purified water outlet port for dispensing purified water outflow from said purification unit. A particulate catalyst retained within the purification unit is in flow through relation relative to said the water inflow and purified water outflow and catalyzes contaminants as the tap water inflow travels through the purification unit. A particulate agitator associated translates vibration to the particulate catalyst for substantially preventing channeling therein during relatively slow tap water inflow through the purification unit.

The sludge dehydrator equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water.

The sludge dehydrator equipment has been designed on the basis of a rectangular tank provided with the necessary infrastructure for containing inside a series of suction plates being connected to a vacuum system, through which the process of solid-liquid separation is carried out and, on the other hand, to contain the cleaning mechanism-the cleaning car-with its motor system made up by pneumatic or hydraulic components required to clean suction plates the filtering medium and to keep them permanently operative.

In accordance with the sludge dehydrator feeding and the design of the lower or bottom cone of the rectangular tank will benefit to be derived from the industrial and mining operation.

Systems, apparatuses and methods related to treating and/or recycling a wastewater for reuse are described.

A method of activating and dewatering sludge through application of acoustic pressure shock waves to wastewater.

A method of treating fluids, including for recovery of water apart from impurities or undesired matter, utilizes application of shock waves to the fluids.

A cleaning system and method of cleaning filters that removes the ash in the plugged regions is disclosed. The filter is subjected to vibrations, which serve to loosen trapped and packed retentate from the filter. The loosened retentate is then captured by a collection bin. The cleaning system can be integral with the intended application, such as within an automobile. In another embodiment, the cleaning system is a separate cleaning station, where the filter is removing from its intended application, cleaned, and then reinstalled.

Disclosed is a method and apparatus for manufacturing a continuous web of polymeric membrane and for continuous downstream processing of said web. The apparatus (10) comprises: a casting station (20) for casting the continuous web (M); a carrier (24) for carrying the web downstream; a membrane drier (30) downstream of the carrier, for drying the web; and a brushing station (40) downstream of the drier for brushing the web. Said drier is located immediately downstream of the carrier, and upstream of said brushing station. The apparatus (10) further includes an additional drying station (50) downstream of the brushing station (40). Brushing after drying retains more surfactant in the membrane which is useful for certain applications. In addition, initial drying eliminates virtually all solvents from the membrane, but leaves some non-solvent (e.g. water) within it, which in turn fixes the surfactant on the nitrocellulose fibers, which improves significantly the consistency and reproducibility of the membrane.

Embodiments provide an apparatus and method for a membrane bioreactor process including a media in the water circulation module. Along with air supplied from bottom of the module the media components are kept in dynamic condition between the gaps to scrub the membrane surface area to it clean in-situ. Continued cleaning of the membrane surface results in benefits of reduced/no physical and chemical cleaning requirement, high flux, low TMP, and reduced frequency of chemical cleaning. The use of highly porous polymeric media having large internal surface area provides the advantage of retention of microbiological culture for a longer time without any disturbance causing an upset condition while increasing the biological loading and treatment capacity of the reactor.
