Chemical Dosing system Boiler Water Treatment three chemical storage tanks five pumps

description

1. The quantity of chemical tank shall be subject to the categories of the dosing drug. (One chemical tank for one kind of drug)

2. The installation of agitating device shall be subject to the property of the drug.

3. The selection of the detector (PH, ORP, concentration detector, conductivity meter) shall be subject to the characteristics of the system.)

Chemical dosing system in the water purification system

Flocculant dosing The HMM flocculant added into the water plays a role of bridging between two particles which will become larger into a large particle flocculating constituent, which is conducive to the precipitation of colloidal and particulate matter in water. So it is usually used before the quartz sand filter.

Chlorine disinfection Chlorine is one of the most widely used disinfectants. It is very applicable and very effective for the deactivation of pathogenic microorganisms. Chlorine can be easily applied, measures and controlled. Is is fairly persistent and relatively cheap. Chlorine has been used for applications, such as the deactivation of pathogens in drinking water, swimming pool water and wastewater

Applications:

Boiler Water Treatment

→ Addition of chemicals to feed water in order to control scale deposits and corrosion

• Phosphates-Dispersants = used for pH and corrosion control
• Hydrazine = used as an oxygen scavenger
• Filming Amines = high pH chemical injected into boiler water
• Neutralizing Amines = used for similar applications
