In these packages, chemical materials in the form of powder or liquid along with water or required chemicals are prepared in a tank and then injected by injection pumps (with different capacities for use in different places). They are transferred from the preparation tank to the injection site. The flow rate can be controlled manually or automatically in order to inject the appropriate amount of chemicals. This package can be used to inject various chemical substances such as coagulant, anti-scalant, polyelectrolyte and chlorine (to disinfect water or sewage). It is used in boilers, drinking water and various industries, including the oil and gas industry.
