摘要： A water-filtration device has a main-filtration path and a bypassing-filtration path, and comprises a filter head (10), a water filter (20), a guiding assembly (30) and an adjusting valve (40) movably mounted at the filter head (10). The guiding assembly (30) is mounted at the filter head (10) and connected to the water filter (20). An O-ring (42) of the adjusting valve (40) can block an end of a bypassing portion (33) of the guiding assembly (30). In the main-filtration path, water passes through filter materials (50) in a first filtrating room (21) and a second filtrating room (22). Water in the bypassing-filtration path passes through the bypassing portion (33) and therefore passes only through the filter material in the first filtrating room (21). The O-ring (42) does not reach into the bypassing portion (33), thereby reducing wear and damage to the O-ring (42).

摘要： A reversible washing, floating bed type reverse sewage treatment system and its treatment methods are provided. Through the light filter sand and reverse sewage treatment system and the sewage filter procedure, the light filter sands float upward and gather at the top of the sewage filter tank to filter the sewage flowing upward. Further, the solid impurities in the sewage are naturally separated from the light filter sands and settle down on the bottom of the sewage filter tank, thereby achieving the effect of maintaining the filtration efficiency and reducing the maintenance of the filter material. Moreover, through the reverse washing jet nozzle and the filter sand cleaning tank and the filter sand reverse cleaning procedure, the water from the reverse washing jet nozzle can clean the light filter sands in the filter sand cleaning tank, thereby achieving the purposes of energy saving and reducing maintenance costs.

摘要： An upflow continuous backwash deep bed sand filter (UCBF) (100) having a recycle line (180, 170, 167) for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF (100). The recycle line (180, 170, 167) returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter (100). Further, a liquid level control unit (130) is provided that reduces fluctuations and significant drop in the liquid level (144) upstream of the upflow continuous backwash filter (100), thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.

摘要： Presented is a liquid filtering apparatus and method that overcomes the disadvantages encountered with prior bed filtration systems by providing a filtering apparatus that incorporates a super-buoyant filter medium having a specific gravity very substantially lower than that of the process liquid being filtered. This feature enables a majority of the medium to float on top of the process liquid. Due to the significant differences in specific gravity between the media and the process liquid, super-buoyant media produce a highly advantageous means of naturally, gravimetrically separating both clean and contaminated filter media and process liquid into separate "phases". Under normal filtering operation, the filter media is contained within a filter housing by a bed support near the top of the filter housing, and particulate material is filtered from a process liquid that passes through the housing. To regenerate the filter media, the housing is drained and a nozzle creates a backwash spray that washes the particulate material from the filter media. During the backwash process, the filter media rises past the nozzle as the level of the backwash liquid in the housing rises, so that the entire filter media is regenerated.

摘要： This self contained, add-on, self cleaning, instant reverse flush aquarium and/or fish-pond filter system is designed to capture all aquarium and/or pond solid detritus and to deposit them in the spaces between a heavy marbles-like filter substrate in such a way that these detritus can then be often and regularly evacuated by reverse-flush action from the filter-body and the vessel containing this filter-body, very fast, very easily, without any in-tank manual intervention and with a minimal amount of water wastage. This instant reverse-flush aquarium and/or fish-pond filter system will be available in many various sizes, shapes or models that can be added at any time to any aquatic life containing vessel of any shape or size, with the purpose of easily evacuating pollution causing debris as often as possible, hereby minimising the need for biological and/or chemical filtration stages and also drastically reducing other stress causing maintenance.

摘要： A sewage treatment system is provided, for cleaning a sewage by filtering solid components in the swage through floating filter medium, wherein the filtration performance can be improved and the filtration cleaning can be performed efficiently. The sewage (18) is flowed into the treatment tank (12) in upward-flow, and filtered through the floating filter media layer (22) made of the meshy cylindrical floating filter medium (20) which have smaller specific gravity than the sewage (18). To wash floating filter medium (20), the air is jetted from the air jetting pipe (54) and the revolution flow is generated to scale solid components adhering to filter medium, and then the sewage (18), which has washed the floating filter medium (20), are discharged to the outside of the tank (12) while the air is jetted from the air jetting pipe (56) for full jetting to jet the floating filter media layer (22) in whole.
