Embodiment Construction

[0051] figure 1 Sewage filtration unit shown. The capillary film 3 is embedded in epoxy resin or polyurethane to seal the gap 4 between the capillary film 3 and the shell 1 . During manufacture, the capillary is potted in resin and cut off at the end, typically 5 mm (millimeters) from the potted end. The tubular, preferably cylindrical housing is provided with a permeate opening 21 in the form of a permeate connector for discharging permeate water from the filter into the clean water sump 11 . Below the permeate connector 21, a backflush opening 6 in the form of a backflush connector is provided in the housing for backflushing the membrane in order to prevent it from clogging. The upper end of the casing is provided with a sewage inlet, and the lower end is provided with a storage tank 7 for storing pollutants from sewage. The housing 1 has a drain valve 8 below the sump 7 for draining pollutants from the sump 7 .

Abstract

Apparatus for filtration of contaminated water, characterized in that the apparatus is provided with a housing (1) which, when oriented for proper use, comprises: a contaminated water inlet (2) and a drain (8, 13), a water filter in the housing, the filter comprising capillary membranes (3) embedded in a sealant at their upper and lower side such that they are completely sealed against the housing, a permeate connector (5) for the drainage of the permeate, a backwash connector (6) for the backwashing of the membrane at the housing, a manually activated pump (9, 10) connected to the backwash connector, wherein the backwash connector (6) is located under the permeate connector (5).

Description

technical field [0001] The present invention relates to devices for sewage filtration, especially for domestic use. Background technique [0002] Millions of people in the world only have access to heavily polluted water, especially water contaminated by bacteria and viruses. Therefore, different kinds of water filtration devices are proposed as point of use devices or household devices. [0003] US Patent No. 4,636,307 and European Patent Application EP 617 951 to Inoue et al. disclose a portable water purification unit having a pre-filter of activated carbon or ion exchange resin in series with a hollow fiber module. [0004] Without a pre-filter, hollow fiber modules have a tendency to clog due to contamination accumulating upstream of the fibers. Clogging of hollow fiber filters is generally known in common filters, such as disclosed in US Patent No. 7,179,636 to Guillot et al., where a peristaltic pump uses backwash to clean the hollow fibers. However, peristaltic pu...
