Flow measuring techniques will vary depending on the application flow type. There are two basic types of flow systems; closed channel, and open channel. A Closed Channel can be described as water flow through a completely filled pressurized pipe.
The pump lift station is used to receive sanitary wastewater or stormwater and move it through a collection system. The lift station can be used to temporarily store the wastewater, but it is generally used to transfer liquid that cannot gravity-flow on its own.
Wastewater from the industrial and business industries can be contaminated with hazardous solids or chemicals. The term “pretreatment” in wastewater refers to the treatment of wastewater before the discharge has a chance to reach a treatment plant.
ParkUSA has two different Holding Tanks. The Decon Tank is used to detain decontamination wastewater containing CBR substances. The aqueous film-forming foam (AFFF) solution is used extensively in fire suppression systems for aviation facilities and fire training facilities.
The ParkUSA Macerator Assembly is an “In-Line Grinder” system used on sewage systems. The unit is recommended for gravity-flow sewer lines which may experience high solid concentrations that can “clog” the sewer piping.
Bar Screen Assemblies
Bar Screen Assemblies are used in an open channel (free surface) flow applications to separate & detain course debris and contraband. These unusual solids have a potential for “clogging” the public sewer line, causing expensive cleaning and downtime of the sewer system.
When a public sewer system is not available, a building sewer is required to have an on-site wastewater treatment system. Local and state authorities typically regulate this type of private sewage disposal system.
