Iron Oxide Pigment Production Wastewater Treatment – Wastewater Overview:
The production of iron oxide pigments typically involves the reaction between iron and nitric acid or sulfuric acid. After a series of chemical reactions and purification steps, various pigments such as iron oxide red, yellow, and black are obtained. During the process, a significant amount of ammonium ions (NH4+) is generated, leading to very high ammonia nitrogen concentrations in the wastewater. Additionally, the pH of the wastewater is extremely low, and it contains high levels of Fe²⺠and Fe³âº, which can cause severe environmental pollution if discharged directly into water bodies.
Our Iron Oxide Pigment Wastewater Treatment System Features:
We have developed an advanced high-concentration ammonia-nitrogen wastewater treatment system that utilizes an efficient stripping technology. This system operates with a gas-liquid ratio of approximately 5500, a pH level around 11.5, and works effectively at temperatures above 25°C. It can achieve an ammonia nitrogen removal rate of over 90%, even when the concentration reaches up to 4000 mg/L.
The system is equipped with a comprehensive control system, including a pH meter, flow sensor, liquid level controller, solenoid valve, and control cabinet. All operational parameters are displayed digitally on the interface, allowing managers to monitor the system easily. The system also includes fault alarms for quick troubleshooting and maintenance. Users can choose from manual, semi-automatic, or fully automatic operation modes based on their specific needs.
Key Characteristics of the Iron Oxide Pigment Wastewater Treatment Process:
1. By using a combined treatment process, the system efficiently handles wastewater with varying concentrations, achieving a high ammonia nitrogen removal rate. After treatment, the effluent meets the national first-class discharge standard, with ammonia nitrogen levels below 15 mg/L.
2. The system is designed to handle flow rates ranging from several tons per hour to hundreds of tons per hour. It can treat wastewater with concentrations as high as 4000 mg/L and still meet strict discharge standards.
3. The equipment is constructed using corrosion-resistant materials such as FRP, carbon steel with anti-corrosion coating, and stainless steel, ensuring long service life and reducing maintenance costs caused by traditional equipment degradation due to corrosive wastewater.
