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 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.

摘要： INTRODUCTION
TECHNOLOGICAL SECTOR
SWID technology can be classified under section CHEMISTRY, class TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE ( C02 ) and under section FIXED CONSTRUCTIONS, class HYDRAULIC ENGINEERING; FOUNDATIONS; SOIL SHIFTING, subclass HYDRAULIC ENGINEERING ( E02B ).
MAIN TECHNICAL FEATURES OF THE INVENTION
SWID technology aims to remove dissolved and undissolved, settleable and unsettleable pollutants from stormwater flowing on large, impermeable areas, taking advantage of the adsorption properties of porous materials.
The main advantages of the system, which differentiate it from the filtration technologies already available on the Market, are the increased hydraulic efficiency, by inducing optimized and calibrated pathways for the stream, with the scope of taking advantage of the whole filtration material's mass available in the plant, and the increased treatment efficiency, by guaranteeing an optimal contact time between water and the filtration media.
Each plant is equipped with a tank containing a series of modular filtration cases, installed vertically one on top of each other to create wheeled towers (Fig. 3). These towers are installed in parallel configuration inside the filtration sector. On the lateral sides of the filtration sector, two horizontal, bidirectional channels for feeding and discharge are installed, as depicted on Figure 4 and 5.
Each modular case is filled with filter media, composed by a selected mixture of highly adsorbing materials, to maximize the performance.
Each modular case is equipped, on its front and back sides, with a calibrated-pore system, in order to calibrate the entering and exiting flowrates of water and guarantee an adequate contact time between water and filtration media, thus enhancing adsorption performance and reducing headlosses (figure 2 and 5).
SWID system can be managed and controlled remotely by means of a SCADA software,connected to a PLC (Programmable Logic Controller) computing system, in order to monitor and control the whole treatment process at each phase, and manage emergencies and maintenance operations.
A tank is located on the front side of the SWID plant for the storage of untreated water during maintenance, emergencies or exceptional contaminant spillovers. Another tank is available for the storage and settlement of the process sludge, collected during the cleaning process run at the end of each process cycle (Figure 9).
When biodegradable organic pollutants (for example, PCBs (polychlorinated biphenyls) are present in water, SWID system is integrated with a process, based on Ozone, to regenerate the filtration media through the destruction of the organic substances.
CONCLUSIONS
With SWID technology, it is possible to manage and treat stormwater runoff flowing on large surface areas, and waste water, by means of highly performing plants, which are also volumetrically compacted, easily to move and without necessity of ground excavation.
