Abstract
A method and arrangement for sewage pre-treatment in a sewer pipeline infrastructure upstream of a sewage treatment facility of a sewage treatment system includes selecting a site in the sewer pipeline infrastructure between a source of untreated sewage and the sewage treatment facility of the system, providing a source of a biological activity enhancing agent at the preselected site, and introducing the agent from the source thereof into a flow of untreated sewage at the selected site so as to convert the sewage from an untreated state to a pre-treated state in the pipeline infrastructure upstream of the sewage treatment facility.
Claims13
A method for introduction of sewage pre-treatment in a pipeline infrastructure of a sewage treatment system upstream of a sewage treatment facility of the system and downstream of an untreated sewage discharging facility, said method comprising the steps of:
- (a) selecting a site in a pipeline infrastructure of a sewage treatment system between and external to an untreated sewage discharging facility and a sewage treatment facility of the system;
- (b) providing a source of biological activity enhancing agent at the selected site, said enhancing agent being an enzyme for increasing the microbial activity in the sewage flow;
- and
- (c) introducing the agent from the source thereof into a flow of untreated sewage at the selected site so as to convert the sewage from an untreated state to a pre-treated state in the pipeline infrastructure upstream of the sewage treatment facility and downstream of said untreated sewage discharging facility.

- (a) selecting a site in a pipeline infrastructure of a sewage treatment system between and external to an untreated sewage discharging facility and a sewage treatment facility of the system;
- (b) providing a source of biological activity enhancing agent at the selected site;
- and
- (c) introducing the agent from the source thereof into a flow of untreated sewage at the selected site so as to convert the sewage from an untreated state to a pre-treated state in the pipeline infrastructure upstream of the sewage treatment facility and downstream of said untreated sewage discharging facility, said introducing of said agent being by use of a mixing device interposed in the piping of the pipeline infrastructure at the selected site and receiving the introduced agent from the source thereof and mixing the agent with the sewage flow at the site.
An arrangement for introduction of sewage pre-treatment in a pipeline infrastructure of a sewage treatment system upstream of a sewage treatment facility of the sewage treatment system and downstream of an untreated sewage discharging facility, said arrangement comprising:
- (a) a selected site in a sewer pipeline infrastructure of a sewage treatment system between and external to an untreated sewage discharging facility and a sewage treatment facility of the sewage treatment system;
- (b) a source of a biological activity enhancing agent provided at said selected site, said agent being an enzyme for increasing the microbial content of the sewage flow;
- and
- (c) means for introducing said agent from said source thereof into a flow of untreated sewage at said selected site so as to convert the sewage from an untreated state to a pre-treated state in the pipeline infrastructure upstream of the sewage treatment facility and downstream of said untreated sewage discharging facility.
An arrangement for introduction of sewage pre-treatment in a pipeline infrastructure of a sewage treatment system upstream of a sewage treatment facility of the sewage treatment system and downstream of an untreated sewage discharging facility, said arrangement comprising:
- (a) a selected site in a sewer pipeline infrastructure of a sewage treatment system between and external to an untreated sewage discharging facility and a sewage treatment facility of the sewage treatment system;
- (b) a source of a biological activity enhancing agent provided at said selected site;
- and
- (c) means for introducing said agent from said source thereof into a flow of untreated sewage at said selected site so as to convert the sewage from an untreated state to a pre-treated state in the pipeline infrastructure upstream of the sewage treatment facility and downstream of said untreated sewage discharging facility, said means for introducing said agent including
- an agent generator at said selected site;
- and
- a mixing device interposed in the pipeline infrastructure at said selected site for receiving said agent from said agent generator and mixing said agent with the sewage flow at said selected site.
