Embodiments describe apparatuses, systems and methods for utilizing a configurable WWTP container having a removable sensor/controller cartridge. Said removable cartridge is configured for collecting and analyzing data for any given configuration of a WWTP container, and is positioned securely separate from the treatment compartment(s) of the WWTP container. The removable cartridge is able to monitor operation conditions of the wastewater treatment compartment(s) via control logic and at least one sensor included in the removable cartridge, and change operating parameters of the container.

The invention discloses a submersible bucket filter system for recirculating deep-water culture (RDWC) systems. The filter comprises a durable container with a submersible pump and filter media basket for mechanical, chemical, and biological filtration. The system functions independently or integrates into totes, ponds, or refugia. It offers two configurations: a weighted version for stability and a twist-lock quick-connect version for portability, ensuring the filter remains submerged even in low water. The system also adapts for pond use, supporting plant growth in aquatic settings.

The invention relates to a spiral pump and a device for treating water comprising this spiral pump, and associated method. The spiral pump comprises: a housing provided with an inlet for water; and a pump body which is accommodated in the housing and rotatable around an axis, wherein the pump body comprises at least one spiral channel, wherein a first outer end of the at least one spiral channel is located on an outer side of the pump body and forms an entrance opening for alternately taking in water and air through rotation of the pump body in the housing, and a second outer end of the at least one spiral channel debouches into an outlet close to the axis, wherein the housing is embodied as pressure chamber and wherein the at least one channel is provided with an increasing diameter from the entrance openings in the direction of the axis.

A rotating biological contactor apparatus includes: a biozone tank containing a liquid being treated; a drive shaft driven to rotate; and at least one media disk. The media disk includes: a substrate having a disk shape defining a first surface and a second surface opposite the first surface, the substrate configured to be attached to the drive shaft and to rotate therewith; and a plurality of fins protruding from at least one of the first surface and the second surface of the substrate and extending for a length in a radial direction to generate a turbulent flow as the plurality of fins pass through a surface of the liquid being treated as the media disk rotates.
