Abstract: A stormwater runoff treatment system that offers an economical means of achieving highly efficient, effective, and compact means of treating runoff through a unique method of flow restrictions, diversions, elevation differences and strategically located components to achieve a combination of treatment advantages.

Abstract: A runoff water vault may be divided into an input chamber which receives runoff water and a second chamber which also separates and stores buoyant and non-buoyant materials separated from the runoff water stream. While the separators in such systems remove particles of different densities than water quite well, they have difficulty in removing neutrally buoyant debris. Screens are added into the water flow stream to catch and remove particles of neutral buoyancy. The screens are mounted in a manner which permits lateral movement of the screen relative to the water flow, such as shaking and/or flexing. Screen movement imparts pressure differential across the screen perforations releasing debris trapped against the screen, so that the debris will fall into an entrainment area and allow increased flow through the screen. The screens may also include one or more turbulator fins for intersecting the water flow and transferring energy to the screen, imparting lateral movement to the screen.

Abstract: An automated system which uses visual tracking technology to monitor the visual direction of a driver's sight, functions to keep the driver's eyes on the road to reduce the danger of potential distractions. When the driver is not looking at the road for a predetermined period, an audio queue, such as a beeping or alarm, will be utilized to bring the driver's attention back to the road. In addition, the system can limit the use of cell phones in the vehicle by disabling cell phones when the driver looks away from the road for greater than a preselected predetermined period. The period can be adjusted to allow for the answering of a hands free phone call, but preventing dialing and texts. The apparatus for alerting the driver includes an optical tracker, a receiver, a processor, and an audible alert device.

Abstract: A treatment system for removal of contaminates includes the introduction of a flocking agent and the settling of resultant aggregations of particulate material, followed by filtration of the remaining water to remove residual flocking agent and particulate matter. Water thus treated is sufficiently clean to discharge into downstream receiving waters, in an effective and efficient manner, and is sufficiently free of flocking agent to avoid being a hazard to aquatic life. The required dose is activated by a rain gauge which meters rainfall over an appropriate time period and evaluated by the microprocessor.

Abstract: A large vault or tank receives the runoff water to be cleaned. There are one or more small tanks in the large tank (vault). Each small tank is inverted and receives water at its open lower end, from the large tank. The water entering the small tank rises, as the water level in the large tank rises, and flows upward through a filter. When the water level rises above the top of the filter it enters an outlet tube or pipe and then flows downwardly along the center-line of the filter. A float, a valve and a check valve may cause the system to function as a siphon and feed the filtered clean water to an outlet. Alternatively the siphoning effect will occur if the inside diameter of said outlet tube is small enough to form a partial vacuum.

Abstract: A filter for filtering fluids is made by stacking two or more strips of flexible material and then wrapping the stack around a center line to form a spiral shaped roll that has several laps of said strips. The resulting roll has an input side which is the bottom wall of a reservoir which contains the fluid to be filtered such as the runoff water from a parking lot. The reservoir may have a by-pass outlet which by-passes the water around the filter in the event that the flow rate of the incoming runoff water exceeds the maximum rate of flow at which the filter is efficient. The strips guide the fluid as the fluid passes through the filter.
