Watering device for animals

Номер: US20120017839A1
Автор: David R. Veness, Steven Green
Принадлежит: Doskocil Manufacturing Co Inc

One embodiment of the present disclosure may take the form of a watering device for animals with continuously flowing water to attract the attention of the animal. To create flowing water, a water screw device may be utilized within the watering device to move water from a lower bowl of the device to an upper bowl. The water screw may be configured such that the electrical components of the water screw remain separated from the water of the watering dish to remove the possibility of electrocution of the water. Rather, only the mechanical components of the water screw device may contact the water of the watering device while the electrical motor of the water screw remains safely out of the water.

System and Process for Removing Nitrogen Compounds and Odors from Wastewater and Wastewater Treatment System

Номер: US20120091045A1
Автор: Daniel T. White, David O'keefe, John D. Cox, Mark B. Robertson
Принадлежит: Biofilter Systems LLC

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. 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, thereby, alter a wastewater process parameter.

Method for Reduction of Oil, Alkalinity and Undesirable Gases Using a Mechanical Flotation Device

Номер: US20120192716A1
Автор: James C.T. Chen, Shaya Movafaghian
Принадлежит: Cameron International Corp

A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.

Aquarium undergravel filter

Номер: US20170013812A1
Автор: Bassam AlThumayri
Принадлежит: Individual

A surface filter for aquarium water purification is placed on the bottom of the aquarium that sucks the waste out of the tank to the canister filter. Small plastic pieces make and connect the main stream channels. Each plastic piece is composed of a couple of inverted pyramids that acts like a funnel. Water flows through the main channels sucked by an external filter. In the base of each inverted pyramid a small hole opens to the drainage channel, which has a hollow inverted V shape. Water, particles and fish waste are passed through the channels to the external filter. At the end of the assembly a cross channel collects the drained water. Collected water is transferred to the external filter outside the aquarium. A hose connects the external filter with the collector. Another hose is connected to the same filter to return the filtered water back to the aquarium.

Systems and methods for clustering particles by liquid-phase electric plasma discharge

Номер: US20140151938A1
Автор: Alexander T. Jordan, Daniel T. Lee, Jeffery S. Hsieh
Принадлежит: Georgia Tech Research Corp

The disclosed technology includes systems and methods for clustering particles, especially water contaminants, by liquid-phase electric plasma discharge. According to certain implementations, the discharge may be applied continuously, and may be of relatively low power, e.g., a voltage between 300 V and 5000 V and an amperage between 0.1 A and 1 A. The electrodes introducing the electric discharge may be in a point-to-point configuration and with at least one electrode having a large aspect ratio. In some implementations, one or more of the voltage and amperage of the electric discharge, electrode configuration and aspect ratio, and the conductivity of the medium may enable the generation of plasma containing hydroxyl and other radicals. The radicals may catalyze polymerization of the particles, resulting in an increase in particle size and, thus, improved filterability. The polymerization process may continue after the electric discharge is discontinued or removed from influence of the medium.
