Abstract: A liquid treatment system is provided having a vault that contains a treatment chamber and an outflow chamber. The treatment chamber may have a filtration media layer containing media that treats liquid as it descends through the filtration media layer, where it will accumulate in a porous layer or open space. The liquid will then be directed through the plurality of pipes to the outflow chamber, where the treated liquid is further directed to outside the system. Accumulated debris settled at the bottom of the treatment chamber may be flushed out by a spray bar.

Abstract: A stormwater vault and a process for servicing the stormwater vault speeds the process of cleaning the stormwater vault. The stormwater vault has a built in liquefaction system for liquefying settled debris in the vault which works together with a sloped or angled floor in the vault and vertical debris cutting spray nozzles. The settled debris is flushed toward the inlet to a vacuum removal line inserted into the vault through an access opening for removing the settled debris from the vault while compacted debris is collapsed by vertically extending water nozzles.

Abstract: Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader having a triangular shape with straight sides, or concave sides or convex sides can split incoming water to pass into dual screen filtration systems. Additionally, an upwardly angled debris ramp above a downwardly angled screened defector can be located on both sides of the flow spreader to help direct debris and trash into dual screened boxes.

A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader can split incoming water to pass into dual screen filtration systems. The system can include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and water pressure lines with spray heads for cleaning debris on a sloped floor.

Abstract: Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media supported by a screen above an angled floor in a vault allows for incoming storm water to pass into a void space above the angled floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. Water sprayers can further liquefy sediment and debris that fills the void space between the angled floor and the bottom of the screen. The captured debris can slide down the angled floor, where a vacuum hose from an above ground vacuum truck can remove the debris and sediment. The long lasting filtration media can be cleaned by being backwashed.

Abstract: Vaults, boxes, systems, and treatment methods to capture pollutants from stormwater runoff and prevent conveyance of the pollutants from entering a receiving water body or landscape area, which can be part of a permanent stormwater drainage infrastructure. A polymer system with at least one polymer log can be used to treat stormwater runoff and any stormwater conveyance, such as a pipe, box culvert, ditchline, and the like. Once stormwater has been dosed with polymers, the treatment easily retains the pollutants, and the one or more polymer logs continue to enhance water quality, while providing an easy method for servicing polymer logs without requiring service technicians to enter the vault. A hydroslide servicing system can include pivotal spray heads to pivot to parallel positions over a sloped floor to flush debris toward easy to reach locations to be vacuumed, and vertical spray heads which can break up debris bridges.
