Description

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
