Additive Dosing System

An Additive Dosing System is a specialized type of chemical dosing system designed to inject precise amounts of additives into a process stream, tank, or pipeline. These additives are usually used to enhance performance, prevent scaling, inhibit corrosion, or improve product quality. ⚙️💧

🔎 What is an Additive Dosing System?

The system ensures that specific chemicals or additives are added accurately and consistently to a process. Unlike general chemical dosing, additive dosing often deals with small volumes of highly potent chemicals that require high-precision pumps and controlled flow.

It is widely used in water treatment, oil & gas, cooling systems, food processing, and industrial manufacturing.

⚙️ Main Components

Additive Storage Tank

Holds the additive solution

Materials: HDPE, PP, FRP, stainless steel

May include agitators to maintain uniform concentration

Dosing Pump

Types:

Diaphragm dosing pump – precise, high-pressure dosing

Peristaltic pump – handles corrosive or viscous additives

Plunger/piston pump – high-pressure industrial applications

Pulsation Dampener

Smooths pulsating flow from the pump

Types: bladder type, gas-filled, volumetric

Calibration Pot / Column

Verifies actual flow from the dosing pump

Piping & Valves

Includes injection valves, check valves, isolation valves

Materials compatible with additives

Flow Meter / Control System (optional)

Monitors dosing rate

Can be connected to PLC or SCADA for automated control

Mixing / Agitation (Optional)

Keeps additives well-dispersed in the tank

Can be top entry or bottom entry agitators
