Ammonia Stripper : Industrial waste water treatment and ammonia removal

An ammonia stripper is an industrial wastewater treatment system designed to remove ammonia from wastewater before discharge or further treatment. It is widely used in pharmaceutical, API manufacturing, chemical, and fertilizer industries & waste mangement companies. Corrowin Enterprises provides customised ammonia stripping solutions based on wastewater flow, ammonia concentration, and site requirements. How Does an Ammonia Stripper Work?
An ammonia stripper generally operates on the principle of air stripping or steam stripping. In an air stripping system, wastewater flows through a packed column while air passes in the opposite direction. The packing increases the contact area, allowing dissolved ammonia to transfer from the wastewater into the air stream.
The wastewater pH is often increased to convert ammonium ions into free ammonia, improving removal. The ammonia-containing exhaust gas may then be treated using an acid scrubber to minimise atmospheric emissions.

Types of Ammonia Strippers
Open-Type Ammonia Stripper: Uses direct air contact in a stripping tower and requires appropriate control of ammonia-bearing exhaust gas.
Closed-Type Ammonia Stripper: Uses an enclosed arrangement to contain ammonia-bearing gas and facilitate its collection and treatment.
The choice depends on wastewater characteristics, process requirements, plant layout, and emission-control needs.
Industrial Applications
Ammonia stripping systems are commonly used in pharmaceutical and API plants, chemical manufacturing units, fertilizer industries, and industrial effluent treatment plants. They can reduce ammonia loading on downstream biological treatment systems and help achieve wastewater treatment targets.

Case Study: Ammonia Removal from Wastewater
A Solid Waste Mangement facility generates wastewater containing elevated ammonia concentrations, creating challenges for its downstream biological treatment plant.
Challenge: Reduce ammonia concentration before biological treatment while controlling ammonia emissions from the stripping process.
Proposed solution: Install a packed-column ammonia stripper with pH adjustment, an appropriately sized air blower, a recirculation or feed system as required, and an acid scrubber to treat ammonia-bearing exhaust gas.
Expected benefits: Reduced ammonia loading on downstream treatment, improved process control, and better management of ammonia emissions.
Actual removal efficiency and treated-water quality must be established through wastewater analysis, design calculations, and performance testing. No specific removal percentage is claimed for this illustrative case.
Corrowin Enterprises offers customised ammonia stripper solutions for industrial wastewater treatment applications. Equipment selection can include suitable column construction, packing media, pumps, blowers, and off-gas treatment systems.
