In today’s industrial landscape, effective water treatment solutions are crucial for maintaining environmental standards and operational efficiency. Murong (Shanghai) International Trade Co., Ltd., based in Shanghai, has established itself as a leading supplier of high-quality water treatment materials and chemicals for international markets. With years of industry experience and a professional team, we specialize in providing comprehensive solutions for various industrial applications, particularly in the printing industry’s waste gas treatment.
Core Industrial Water Treatment Products
Our product range includes several key materials essential for effective water treatment and industrial applications:
1. Industrial Activated Carbon
As a primary product in our portfolio, we offer various forms of activated carbon including coconut shell granular activated carbon, powdered activated carbon, columnar activated carbon, spherical activated carbon, and honeycomb activated carbon. These products are specially designed for:
- Adsorption of organic pollutants in water treatment
- Removal of odors and volatile organic compounds (VOCs)
- Specialized applications in printing waste gas treatment
- Purification processes in chemical and pharmaceutical industries
Our activated carbon products have demonstrated excellent performance in Korean printing facilities, effectively treating waste gas containing ink solvents and other volatile compounds. The high surface area and pore structure of our activated carbon ensure maximum adsorption efficiency.
2. Polyacrylamide (PAM)
Polyacrylamide is an essential flocculant in water treatment processes. Our product range includes:
- Anionic polyacrylamide for wastewater treatment
- Cationic polyacrylamide for sludge dewatering
- Non-ionic polyacrylamide for specific industrial applications
These products help in the aggregation of suspended particles, facilitating their removal from water. In printing facilities, PAM plays a crucial role in treating wastewater containing ink residues and other contaminants.
3. Citric Acid
Our food-grade and industrial-grade citric acid serves multiple purposes in water treatment:
- pH adjustment in water treatment systems
- Chelation of metal ions to prevent scaling
- Component in cleaning formulations for industrial equipment
- Natural preservative in various applications
In printing facilities, citric acid helps maintain optimal conditions in waste gas treatment systems and prevents corrosion of equipment by neutralizing alkaline components.
4. Anthracite Filter Media
Our high-quality anthracite filter media provides excellent filtration performance for:
- Removal of suspended solids in water treatment
- Pre-filtration before activated carbon adsorption
- Multi-media filtration systems
- Industrial process water treatment
The hardness and durability of our anthracite make it ideal for long-term use in demanding industrial environments, including printing facilities where consistent water quality is essential for equipment longevity.

FAQ
What makes activated carbon effective for printing waste gas treatment?
Activated carbon’s effectiveness comes from its high surface area and porous structure that provides millions of adsorption sites per gram. For printing waste gas, we recommend honeycomb activated carbon which offers optimal airflow resistance and maximum contact time with the gas stream, ensuring efficient removal of VOCs and odors.
How often should activated carbon be replaced in waste gas treatment systems?
The replacement frequency depends on several factors including the concentration of contaminants, airflow rate, and operating hours. Typically, in printing facilities, we recommend monitoring pressure drop across the carbon bed and replacing when it reaches 1.5-2 times the initial value or when breakthrough of contaminants is detected in the outlet gas.
What are the main advantages of using anthracite filter media in water treatment?
Anthracite offers several benefits: 1) High hardness reduces media attrition and dust generation 2) Sub-angular shape provides excellent filtration efficiency 3) High specific gravity ensures good settling characteristics 4) Chemical resistance allows use with various water qualities. In printing facilities, it helps protect downstream equipment by removing suspended solids from process water.
How does polyacrylamide improve wastewater treatment in printing plants?
Polyacrylamide acts as a flocculant by neutralizing charges on suspended particles, causing them to aggregate into larger flocs that settle more rapidly. In printing wastewater, it helps remove ink particles, paper fibers, and other contaminants, reducing turbidity and improving water clarity for reuse or discharge.
What precautions should be taken when handling citric acid in industrial settings?
While citric acid is generally safe, proper handling includes: 1) Using appropriate personal protective equipment (gloves, goggles) 2) Storing in a cool, dry place away from incompatible materials 3) Following recommended dilution rates to prevent excessive acidity 4) Ensuring proper ventilation when handling large quantities. Our team provides detailed safety data sheets with every shipment.
