Abstract:
A system is provided for verifying operation of a plurality of alarm systems in a plurality of environmental equipment systems that comprises a plurality of first communication nodes and a plurality of second communication nodes. Each second communication node is typically mounted within a yard to about six hundred yards from respective first communication nodes. The first communication nodes send a first verification signal, e.g., a heartbeat signal to verify the alarm systems to the second communication nodes at first predetermined intervals. The plurality of second communication nodes detect when the first verification signal is not received at the first predetermined intervals. The second communication nodes then determine whether to send a malfunction notification to a server base on predetermined criteria. The second communication nodes may send a second heartbeat signal to the server at other predetermined intervals.
Abstract:
A system for introducing a liquid disinfectant into treated wastewater comprising a source of liquid disinfectant, a sensor to detect flow or level of treated wastewater from a wastewater treatment system, a selectively operable valve to allow the liquid disinfectant to flow via gravity into the treated wastewater and a controller operatively connected to the sensor to open the valve in response to sensed, increased flow or level of the treated wastewater in a receiver for said wastewater above a sensed, predetermined point.
Abstract:
A sparse data system is provided for verifying operational compliance of a plurality of environmental systems. To reduce operational costs to a minimum, the quantity of data transmitted is minimized and the data is only transmitted at certain times. If systems are compliant, then information is preferably not sent. If systems are non-compliant, then notices are sent to parties of interest at effectively the same time as the noncompliance occurs. Subsequent alarm detection level may also be sent after detection of an operational threshold to provide notice for continued ongoing or severe noncompliance.
Abstract:
A vessel assembly for use in a wastewater treatment system having a first vessel, a second vessel, a first gusset assembly attached to and connecting the first and second vessels and a second gusset assembly attached to and connecting the vessels, at least one of the gusset assemblies provides an upwardly facing surface or pocket for holding fill materials such as dirt or gravel to counter buoyancy acting on the vessel assembly.
Abstract:
An aerator assembly for use in the aeration vessel of a wastewater treatment system comprising a rigid tubular member having an upper end and a lower end, and a diffuser assembly, the diffuser assembly comprising a flexible connector and a diffuser head, the flexible connector connecting the diffuser head to the lower end of the rigid tubular member and providing a fluid flow path between the tubular member and the diffuser head, the upper end of the rigid tubular member being adapted to be connected to a source of an oxygen-containing gas such as air.
Abstract:
An apparatus for treating wastewater with a liquid disinfectant comprising a vessel for wastewater, a pump in the vessel, a discharge conduit connected to the outlet of the pump for discharging water from the vessel, a first valve in the discharge conduit to control flow through the discharge conduit, a recirculation conduit connected to the pump discharge for recycling at least a portion of the wastewater discharged from the pump back into the vessel, a container for liquid disinfectant, a feedline connected to the container to feed disinfectant into the vessel, a second valve in the feedline to control the flow of disinfectant through the feedline and a control system connected to the pump and the first and second valves to selectively cause opening and closing of the first and second valves at desired intervals for predetermined periods of time and selectively activate the pump at desired times for predetermined periods of time.
Abstract:
A system for introducing a liquid disinfectant into treated wastewater comprising a source of liquid disinfectant, a sensor to detect flow of treated wastewater from a wastewater treatment system, a pump to introduce the liquid disinfectant into the treated wastewater and a controller operatively connected to the sensor to activate the pump in response to increased flow of treated wastewater above a sensed, predetermined flow rate.
Abstract:
A defined current and aeration system for the aeration chamber of an aerobic wastewater treatment plant is disclosed. It includes the release of oxygenation gas or air into the aeration chamber through a diffuser or the like at a position such that the air injected into the tank provides the necessary amount of oxygen for aerobic bacterial digestion of the waste while creating a current or circulation pattern in the chamber that forces every portion of the fluid within the aeration chamber into circulation thus preventing the accumulation of solids as sludge in the wastewater treatment plant.
