Problems solved by technology

However, some substances in wastewater, such as oil and grease, adhere at the distal surface of the filter membrane and cannot be removed from the filter surface of the membrane by rising air bubbles, eventually causing the membrane filter to become clogged

Embodiment Construction

[0034] figure 1 A process water analysis device 10 for continuously analyzing water samples of wastewater 14 is schematically shown. Wastewater 14 flows continuously into a primary wastewater tank 12 through a tank inlet 16 and out of the wastewater tank 12 through a tank outlet 18, thereby creating a total waste water within the wastewater tank 12 between the inlet 16 and the outlet 18 Stream 20. Process water analysis device 10 is configured for quasi-continuous determination of one or more analytes (eg, ammonium and / or phosphate) of wastewater 14 and may be part of a wastewater treatment facility.

[0035] The process water analysis device 10 basically includes a water sampling immersion probe 50 that is submerged into the wastewater 14 and held and positioned by a rigid holding structure 54 . The immersion probe 50 is fluidly and electronically connectable to a landside control unit 30 comprising a sample pump 34 , an air pump 32 for aeration and a water analysis device ...

Abstract

The present invention relates to a water sampling immersion probe (50) for continuously filtering a water sample from wastewater (14). The water sampling immersion probe (50) includes a distal coarse filter (60) with a porosity of 0.1 to 1.0 mm, a proximal fine filter (70) arranged downstream of the coarse filter (60) and having a porosity of less than 5.0 (mu)m, and a sample suction opening (74) arranged downstream of the fine filter (70). The coarse filter (60) is arranged to not contact the fine filter (70).

Description

technical field [0001] The present invention relates to a water sampling immersion probe for continuously filtering water samples from wastewater. Background technique [0002] Fixed water sampling immersion probes are used as part of process water analysis equipment for the analysis of one or more analytes in water, for example in wastewater ponds that are part of wastewater treatment facilities in wastewater. [0003] A typical stationary water sampling immersion probe is described in DE 10 2004 037 226 B3. The water sampling immersion probe is provided with two individual sloped filter membranes which are cleaned intermittently by providing air bubbles at the bottom of the membranes. The air bubbles rise along the surface of the filter membrane and thereby mechanically clean the surface of the filter membrane. However, some substances in wastewater, such as oil and grease, adhere at the distal surface of the filter membrane and cannot be removed from the filter surface...
