Abstract: A wastewater treatment system includes a wastewater collection system, at least one aeration subsystem aerating the aerobic portion, and at least one filtration subsystem. The wastewater collection system has an anoxic portion, an aerobic portion downstream of the anoxic portion, an anaerobic portion downstream of the aerobic portion. The filtration subsystem includes at least one bioreacting filter receiving fluid from the aerobic portion, being operable to filter wastewater received from the aerobic portion, and discharging filtered fluid into the anoxic portion, an oxygen contactor fluidically connected between the aerobic portion and the at least one bioreacting filter and operable to diffuse oxygen into the fluid being supplied from the aerobic portion, and an oxygen supply operable to supply oxygen to the oxygen contactor.

Abstract: A treatment system for water having contaminants includes a contaminant-removing tank processing the contaminated water, the tank comprising an interior and a floor defining therebelow at least one depression having a conical shape that upwardly expands from a nadir to the floor, a fluidized bed within the at least one depression and defining a lower bed portion, and a manifold fluidically connected to a contaminated water supply and directing the contaminated water towards the nadir of the depression into the lower bed portion of the fluidized bed to act as a bioreactive filter that removes contaminants out from the contaminated water when the contaminated water flows through the fluidized bed and into the interior of the tank.

Abstract: A wastewater treatment system includes independent wastewater treatment facilities. Each of the facilities has a number of wastewater treatment subsystems. A wastewater collection subsystem holds wastewater to be treated. A pump subsystem moves wastewater from a wastewater collector to a filtration subsystem having a bioreacting filter. The filter has a sump and a fluidized-bed filter therein and supports the filter upright. The filter has an upwardly expanding, hollow, conical filter body with filter media. A monitoring subsystem measures wastewater process parameters. Control devices receive control commands and, dependent upon the command received, alter parameters of the wastewater treatment subsystems.

Abstract: A method is provided for sharing data, stored on a central data store, between a first user and a secondary user. The method comprises the following steps. A share request message is received from the first user. The share request message includes a data identifier for identifying which of the data stored on the central data store is to be shared with the secondary user, and a user identifier for identifying the secondary user. The data to be shared is associated with an account of the secondary user for subsequent access by the secondary user. A system and computer readable medium configured to implement the method are also described.

Abstract: A calendar application for use with a first portable electronic device includes time-dependent events having a start time and an end time and proximity-dependent events having a specified device ID that corresponds to a second portable electronic device. Both the time-dependent events and the proximity-dependent events are stored in the calendar application and the proximity-dependent event is convertible into a time-dependent event. A proximity reminder is generated when the second portable electronic device is in short range radio frequency communication range of the first portable electronic device.

Abstract: A wastewater treatment system includes independent wastewater treatment facilities. Each of the facilities has wastewater treatment subsystems and is monitored by a central monitoring location. Wastewater collection subsystems hold wastewater to be treated. Monitoring subsystems measure wastewater process parameters. Control devices receive control commands and, dependent upon the command received, alter parameters of the wastewater treatment subsystems. A communication device connects the wastewater treatment subsystems and the control devices and sends information corresponding to the wastewater process parameters measured by the monitors, receives control messages corresponding to the control commands, and transmits control commands the control devices to alter wastewater process parameters.
