Abstract
A method to feed a chemical into a liquid flow using a feed device including a nozzle casing having an isolated mixing space including: feeding the chemical to the isolated mixing space in the feed device; feeding a mixing liquid to the isolated mixing space; mixing the chemical and the mixing liquid in the isolated mixing space to form a mixture of chemical and mixing liquid, and feeding the mixture of chemical and mixing liquid to the liquid flow.

A method to feed a chemical into a liquid flow using a feed device including a nozzle casing having an isolated mixing space, said method comprising:
- feeding the chemical to the isolated mixing space in the feed device, wherein the nozzle casing is disposed at least partially in the liquid flow;
- feeding a mixing liquid to the isolated mixing space;
- mixing the chemical and the mixing liquid in the isolated mixing space to form a mixture of chemical and mixing liquid, and
- feeding the mixture of chemical and mixing liquid to the liquid flow.
A method to feed a chemical into a liquid flow using a feed device including a nozzle casing including an isolated mixing space, a closed end proximate to the isolated mixing space, a chemical feed duct having a outlet at the isolated mixing space and a mixing liquid feed duct in fluid communication with the isolated mixing space, said method comprising:
- feeding the chemical through the chemical feed duct and discharging the chemical from the outlet into the isolated mixing space;
- feeding the mixing liquid through mixing liquid feed duct to the isolated mixing space;
- mixing the chemical and the mixing liquid in the isolated mixing space to form a mixture of chemical and mixing liquid, wherein the mixing in the isolated mixing space is impervious to the liquid flow, and
- feeding the mixture of chemical and mixing liquid from the isolated mixing space to the liquid flow, wherein at least a portion of the closed end extends into the liquid flow.
