Abstract: A separator prevents microplastics from entering the environment by regenerating the pressure consumption of filters for removing microplastics in effluent from any source but in particular removing microfibers from domestic and commercial washing machine wastewater, industrial textile processing waste and roadside runoff. The separator separates microplastics from an effluent, and includes a chamber with an inlet and an outlet, a sieve structure forming a permeable barrier between the inlet and the outlet to filter the effluent, and a pump in fluid communication with the outlet of the chamber.

Abstract: A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

Abstract: The present technology relates to control systems for use with fluid treatment systems. In one embodiment, for example, a fluid treatment system includes a vessel configured to receive a fluid having one or more constituents and to separate one or more constituents from the fluid. The system can also include a tube extending along at least a portion of the vessel and a sensor. The tube can be in fluid communication with a pressurized air source, and the sensor can be configured to obtain a measurement of an operating parameter. The system can also include a controller in communication with the sensor and pressurized air source. The controller can execute one or more algorithms to determine a filter parameter based on the measurement of the operating parameter, compare the filter parameter to a threshold, and, based on the comparison, activate or deactivate the pressurized air source.

Abstract: The invention relates to a method for washing a filter (F) having at least two layers of filtering media (4, 5) for raw water containing components having a tendency to form cakes (M), in particular for seawater, the layers of filtering media being supported by a base (6) comprising pass-through openings and provided with nozzles (6a) enabling air and/or wash water to be injected, the raw water flowing through the layers from top to bottom and the treated water being recovered at the lower portion of the filter, and which comprises at least one spillway (D) at the upper portion thereof for collecting the wash water. The method includes the following series of steps: a) the raw water intake (2) is closed, followed by the filtration outlet valve (13), the filter is depressurized, and the filter cake is broken; b) the water level in the filter is lowered; c) only pressurized air is blown into the lower portion of the filter, said air passing through the layers of the filter from bottom to top and causing the cakes to be reduced to particles, in particular by means of friction; d) rinsing is carried out from bottom to top using only water, the water rinsing time being sufficiently short to ensure that the water level stops below the level of the upper edge of the wash water collection spillway; e) the filter water is emptied once again by discharging same from the lower portion of the filter; f) steps c), d) and e) are repeated at least once, and a final rinsing is carried out by injecting a quantity of backwashing water through the bottom portion of the filter, which is then discharged from the upper portion of the filter via a pipe (14).
