A fluid flow control and debris intercepting apparatus for controlling the flow of fluid and the introduction of debris into the entrance of a conventional curbside storm drain of the character having spaced apart side walls that define a fluid flow channel through which fluid flows. Additionally, the apparatus senses the nature and extent of contaminants contained within the fluid.

The disclosure relates to a sampling system for processing a liquid sample, including a retrieving module configured to be fluidically connected to a liquid-source and configured to retrieve a liquid sample from the liquid-source, a filling module configured to fill the retrieved liquid sample into a sampling container, a storing module configured to store the sampling container filled with the liquid sample, and a disposal module configured to discard the liquid sample.

A wastewater sampling system including: an inlet tube; an outlet port; a high-flow circuit fluidly coupling the inlet tube to the outlet port; a first pump, along the high-flow circuit, configured to pump wastewater through the high flow circuit; a sampling circuit, fluidly coupled to the high-flow circuit via a junction, comprising a solid waste filter fluidly coupled to the junction and a solid-phase extraction cartridge fluidly coupled to an outlet of the solid waste filter; a second pump along the sampling circuit; a controller configured to, during a sampling cycle at a first time, activate the first pump; at a second time, activate the second pump; and at a third time succeeding the second time by a sampling duration, deactivate the second pump.

A device to extract a near continuous stream of sample water from a high solids content source for the purpose of delivery to a liquid analyzer or sensor for test or measurement. The device includes a source of compressed air and a source of chemical cleaning agent that are used in a coordinated effort to purge and clean the sampling system to ensure the water stream is maintained over long periods of time without significant human intervention. The device includes a valve to allow compressed air to intermittently be sent backwards through the sampling line to purge to drain an inline strainer of solids that have built up since the previous air purge. Downstream of the air valve another valve is used to introduce cleaning chemical into the sampling system to clean residual buildup downstream of the inline strainer. A debubbler unit is placed between the air valve and the cleaning chemical valve to remove air from the sampling system after it was introduced during the air purge event.

A fats, oils, and grease waste materials water sampling apparatus includes a housing having an inlet, an outlet, a floor to accommodate a sampling jar below the inlet and an open top. The floor in the housing includes a recessed bottom, the recessed bottom extending between the inlet and the outlet to facilitate receipt of a sample jar for fats, oils, and grease waste materials sampling. Systems and methods for the invention are also described.

The present invention relates to a water sampling immersion probe (50) for continuously filtering a water sample from wastewater (14). The water sampling immersion probe (50) includes a distal coarse filter (60) with a porosity of 0.1 to 1.0 mm, a proximal fine filter (70) arranged downstream of the coarse filter (60) and having a porosity of less than 5.0 m, and a sample suction opening (74) arranged downstream of the fine filter (70). The coarse filter (60) is arranged to not contact the fine filter (70).
