Problems solved by technology

However, its minimum flow rate was exceeded several times during the peak period and barely reached the rest of the time
The result is constant clogging, causing increased maintenance requirements and costs

Embodiment Construction

[0048] figure 1 A basic schematic diagram of a pressurized drainage system for waste water is shown, where only a number of stations are shown, designated by the letters A to L, so as to show the central communication structure. The pump station 2 is in wireless communication with the central control unit 3 . The central control unit is connected to a computer unit 9 via a network 8, for example via the Internet. The computer unit 9 can thus monitor, optionally configure and / or control the central control unit 3 . For this purpose, the control unit 3 provides a web interface via a web server, the interface of which can be displayed on the computer unit 9 .

[0049] The central control unit 3 includes a processing unit 5 , a computer system or microprocessor system connected to the data memory 4 . It should be noted that its data memory may be directly in one embodiment, and in another embodiment indirectly connected to the processing unit 5, for example via a network, such ...

Abstract

The invention relates to a method of operating a pressurized wastewater-drainage system (1) having interconnected line sections (SA1...SA9) for conducting wastewater to a transfer station (10) and a plurality of pump stations (2) connected to the line sections (SA1 ...SA9) for collecting the wastewater, wherein at least a portion of the pump stations (2) transmits at least status information indicating its respective pump standby status to a central controller (3), wherein a group is formed from the set of pump stations (2) that are in pump standby in relation to one of the line sections (SA1 ...SA9) such that the number of pump stations (2) of the group corresponds at least to a minimum number (p min) of pump stations (2) associated with this line section (SA1 ...SA9), and the pump station (2) or pump stations (2) of the group are then activated simultaneously by the central controller (3). A minimum flow rate is thus present in wide portions of the pressurized drainage system and for a maximum time, which results in a cleaning effect and thus reduces the danger of clogging.

Description

technical field [0001] The present invention relates to a method of operating a pressurized drainage system for waste water, wherein said pressurized drainage system has interconnected sections for directing water to transfer stations and a number of pumping stations connected to the sections for collecting the wastewater. Background technique [0002] Pressure drainage systems have been known for decades and are used all over the world. Many applications for wastewater transport based on this principle can be found in the United States, Europe, Asia, and Africa. It is an attractive alternative to conventional gravity-based wastewater transport due to its technical advantages. Pressure drainage systems allow one to create wastewater treatment infrastructure in areas where systematic wastewater treatment is not possible for technical or economic reasons. [0003] While a conventional gravity-based wastewater system requires between 0.05% and 1% inclination of the sewer to a...
