Abstract
A method of mixing at least two chemicals or additives into a process liquid flow flowing in a process liquid flow duct including: feeding a liquid jet to the process liquid flow in the process liquid flow duct, wherein the liquid jet is formed in a feeding device and the liquid jet flows in a transverse direction to a flow direction of the process liquid flow through the process liquid flow duct; mixing the at least two chemicals or additives together to form a mixture; feeding the mixture of the at least two chemicals or additives into the process liquid flow duct with the feeding liquid jet, and mixing the at least two chemicals or additives with the feeding liquid jet in the process liquid flow duct.

A method of mixing at least two chemicals or additives into a process liquid flow flowing in a process liquid flow duct comprising:
- feeding a liquid jet to the process liquid flow in the process liquid flow duct, wherein the liquid jet is formed in a feeding device and the liquid jet flows in a transverse direction to a flow direction of the process liquid flow through the process liquid flow duct;
- mixing the at least two chemicals or additives together to form a mixture;
- feeding the mixture of the at least two chemicals or additives into the process liquid flow duct with the feeding liquid jet, and
- mixing the at least two chemicals or additives with the feeding liquid jet in the process liquid flow duct.
An apparatus for feeding at least two chemicals or additives to a process liquid flow flowing in a process liquid flow duct, the apparatus comprising:
- a feeding device having a first inlet connection to receive a feeding liquid,
- a second inlet connection for a first chemical or additive;
- a feed connection for the feeding liquid and the chemical or additive,
- a third inlet connection for a second chemical or additive introducing the second chemical or additive in the same space with the first chemical or additive within the feeding device.
A method of mixing a plurality of chemicals or additives into a process liquid flow flowing in a process liquid flow duct comprising:
- forming a liquid jet in a feeding device which injects the liquid jet into the process liquid flow duct transversely to a flow direction of the process liquid flow through the process liquid flow duct;
- mixing the chemicals or additives to form a mixture;
- feeding the mixture directly into the process liquid flow duct using a pressure difference formed by the feeding liquid jet entering the process liquid flow duct, and
- mixing the mixture of chemicals or additives with the feeding liquid jet in the process liquid flow duct.
