Which pumps are commonly used for chemical dosing?
Chemical dosing pumps that are used for water treatment fall into the following categories: centrifugal pumps, piston pumps, and displacement style pumps (peristaltic and diaphragm pumps).
What is chemical dosing in water treatment?
Chemical dosing is the adding of chemicals into water/fluid or sludge to achieve required conditioning. This would make the treatment effective by various mechanisms such as charge neutralisation, settling of solids etc.
What is a chemical dosing skid?
Chemical dosing skids (also referred to as chemical metering or injecting skids) are modular systems to support pumps, piping, and valves for applications that require metered chemicals. These systems are easily transported and can be prebuilt to reduce setup time and costly in-plant piping runs.
Where are dosing pumps used?
Metering or dosing pumps are used extensively for controlled chemical addition to a process. They can be of almost any type depending on the metering accuracy required.
Why are dosing pumps used?
Dosing pumps are used in the chemical industry and for the production of pharmaceutical products, for the manufacturing of food and beverages, for water and wastewater applications, and to dose adhesives in automated packaging processes and fill fuels into tank systems.
What is DSS pump?
Grundfos Dosing Skid Systems (DSS) are designed to feed liquid chemicals from a supply source (usually tank or drum) to an injection point. Grundfos DSS range from pre-engineered, standard one, two and three pump systems, to custom systems with multiple pumps and tanks all piped on a common skid complete with controls.
How does a calibration column work?
How does it work? For the calibration of a chemical feed system, the Calibration Column is to be filled with water or any other neutral fluid to the top mark; close the valve from the chemical feed tank; start the metering pumps and draw down the chemical in the column for 30 seconds; stop the metering pump.
What is chemical pump?
What is a chemical pump? Chemical pumps are used to transfer chemicals and are designed to be resistant to corrosive and abrasive industrial liquids such as fuel, paint, bleach, solvents, etc. Chemical pumps can be either centrifugal pump or a positive displacement pump depending on the specific application.
