A fuel strainer assembly includes a filtration member and an inlet connector connected to the filtration member for connection to an inlet of a fuel pump. The fuel strainer assembly also includes a push pad connected to the filtration member. The fuel strainer assembly further includes a compression retainer operatively supported by the push pad to engage the inlet connector to cause an interference fit between the inlet connector and the inlet of the fuel pump to secure the inlet connector to t...

A method of treating sewage sludge comprises incubating raw sludge at a temperature in the mesophilic range to reduce the pathogen content of the sludge.

A new biofilm-activated sludge Sequencing Batch Reactor (SBR) treatment process for sewage or wastewater has successfully been developed as the third generation SBR (SBR3). This new SBR3 process utilizes a multi-stage and multi-sludge SBR configuration receiving either continuous or intermittent inflow of wastewater. Each stage has individually controlled continuous or alternating anaerobic/anoxic/aerobic operation, with or without mixing and recycling from the other stage(s). The configuration ...

A fuel strainer assembly includes a filtration member and an inlet connector connected to the filtration member for connection to an inlet of a fuel pump. The fuel strainer assembly also includes a locking mechanism operatively supported by the inlet connector to operatively engage a shell of the fuel pump to secure the inlet connector to the fuel pump.

A swimming pool cleaning apparatus that includes a housing with a substantially hollow cavity that runs along the longitudinal axis of the housing; a handle means mounted to the housing for providing directional control and movement of the housing; a wheel means movably mounted to the housing for facilitating forward, backward, and angular movement of the housing along a swimming pool surface; a debris agitator means rotatably attached to the housing to facilitate water movement through the hous...

A fluid separation system includes a tank with a storage chamber for retaining floating and non-floating particulates. The tank includes a baffle for retaining floating particulates within the storage chamber and for directing flow out of the storage chamber. The tank also includes a bypass with an inlet flow control zone and an outlet flow control zone. The flow control zones are separated by a weir sized and positioned to regulate the fluid flow through a baffle port into the storage chamber. ...

The present device is a fuel supply device to pressurize and supply fuel F which is stored in a fuel tank 10, which comprises a fuel supply pipe 11 which forms a supply passage for the fuel F, a fuel filter 12 to filter the fuel F disposed at the midway of the fuel pipe 11 and below the fuel tank 10, a fuel pump 13 to pressure-feed the fuel F disposed at the downstream side than the fuel filter 12, and a venting pipe 15 to connect the downstream side of the fuel filter 12 and an upper air-space ...

An apparatus for reclaiming coolant used in cutting machines and for returning the reclaimed coolant to the coolant system of the cutting machine is provided. The apparatus includes a shallow receptacle for supporting a barrel that cuttings are deposited into during a milling operation of a work piece. The apparatus includes a flange that extends from an inner surface of the receptacle and supports the bottom of the barrel allowing coolant to drain from the barrel into the receptacle. The collec...

A method of treating wastewater sources such as those from pulp and paper mills which contain lignin involves adding white rot fungi in the presence of glucose. While glucose may be directly added to the wastewater source, it has been found to be more economical to reduce or substantially remove color from the wastewater by additionally adding brown rot fungi in the presence of cellulose and hemi-cellulose. The addition of bacteria has also been found helpful to improve the reduction in color, b...

A hydraulic oil filtration apparatus 40 comprises an actuation control valve V, a pump-pressure oil passage 41, a connection oil passage 43, a tank oil passage 51, a return filter 60, a drain oil passage 53, a drain filter 70 and an aspirator structure 90. The actuation control valve V controls to charge and discharge a hydraulic actuator A such as a boom cylinder 22 and travel motors with hydraulic oil from a hydraulic pump P, which is connected through the pump-pressure oil passage 41 to the a...
