In today’s industrial landscape, water treatment plays a crucial role in ensuring environmental compliance, operational efficiency, and product quality. Murong (Shanghai) International Trading Co., Ltd., based in Shanghai, has established itself as a leading supplier of high-quality water treatment materials for industrial applications. With years of industry experience and a commitment to technological innovation, the company offers a comprehensive range of products including activated carbon, polyacrylamide, citric acid, and anthracite filter media.
Premium Activated Carbon Solutions for Industrial Applications
Murong Trading offers a diverse range of activated carbon products specifically designed for industrial water treatment applications. Our product lineup includes coconut shell granular activated carbon, powdered activated carbon, columnar activated carbon, spherical activated carbon, and honeycomb activated carbon. Each type is engineered to address specific treatment requirements across various industries.
Coconut shell activated carbon stands out for its superior adsorption capacity, making it ideal for removing organic contaminants, chlorine, and odors from industrial wastewater. The micro-porous structure provides extensive surface area (typically 900-1100 m²/g) for efficient pollutant removal. Our granular activated carbon (GAC) products come in sizes ranging from 4×8 mesh to 20×40 mesh, allowing for customized filtration solutions based on flow rates and contact time requirements.
For applications requiring rapid adsorption rates, our powdered activated carbon (PAC) offers excellent performance. With particle sizes typically below 50 microns, PAC provides immediate contact with contaminants, making it suitable for emergency spill response and peak load treatment scenarios. The company maintains strict quality control measures to ensure all activated carbon products meet ASTM standards for iodine number (800-1100 mg/g), hardness (90-98%), and ash content (<5%).
Advanced Polyacrylamide Products for Water Treatment
As a professional polyacrylamide supplier, Murong Trading offers both anionic and cationic polyacrylamide (PAM) formulations tailored to specific industrial water treatment needs. Our polyacrylamide products serve as highly effective flocculants and coagulants in wastewater treatment processes, helping to remove suspended solids, organic matter, and heavy metals.
The anionic polyacrylamide series features molecular weights ranging from 8-22 million, with charge densities from 10-40%. These products excel in treating inorganic suspended solids commonly found in mining, metallurgical, and coal washing wastewater. The cationic polyacrylamide range, with charge densities from 5-60%, is particularly effective for organic sludge dewatering in food processing, paper making, and pharmaceutical industries.
Our technical team works closely with clients to determine the optimal polyacrylamide formulation and dosage for their specific applications. Proper selection and application of polyacrylamide can significantly improve sedimentation rates, reduce sludge volume, and lower overall treatment costs. All our products comply with international standards including ISO 9001:2015 quality management system certification.

High-Purity Citric Acid for Industrial Water Treatment
Murong Trading supplies premium industrial-grade citric acid that serves multiple functions in water treatment processes. Our citric acid anhydrous and monohydrate forms are manufactured to meet strict quality standards, with purity levels exceeding 99.5%. The product’s excellent chelating properties make it effective for removing metal ions such as calcium, magnesium, and iron from industrial water systems.
In cooling water treatment applications, citric acid acts as a threshold inhibitor, preventing scale formation by sequestering hardness ions at low concentrations. This property helps maintain optimal heat exchange efficiency in industrial cooling systems while reducing the need for harsh chemical scale inhibitors. The product’s biodegradability makes it an environmentally friendly alternative to traditional chemical treatments.
Our citric acid also functions as a pH adjuster in various water treatment processes. With a pKa value of 3.1, it provides precise pH control in the range of 3-6, which is critical for many industrial applications including wastewater neutralization, metal surface treatment, and boiler feedwater conditioning. The product’s high solubility (133 g/100ml at 20°C) ensures rapid dissolution and uniform distribution in treatment systems.
Superior Anthracite Filter Media for Industrial Filtration
As a leading anthracite filter media supplier, Murong Trading offers high-quality anthracite coal specifically processed for water filtration applications. Our anthracite filter media is sourced from premium coal deposits and undergoes rigorous processing to ensure consistent size distribution and purity levels exceeding 95% fixed carbon content.
The product’s unique physical properties make it an excellent choice for multi-media filtration systems. With a specific gravity of 1.5-1.6 g/cm³, our anthracite provides superior filtration performance compared to traditional sand media. The angular particle shape creates void spaces that enhance particle interception while maintaining optimal flow rates. The hardness rating of 3.5-4.0 on Mohs scale ensures long service life with minimal attrition loss.
Our anthracite filter media is available in sizes ranging from 0.5mm to 2.5mm, allowing for customized filtration solutions based on specific application requirements. The product’s excellent chemical stability makes it compatible with a wide range of water treatment chemicals including chlorine, ozone, and permanganate. It effectively removes suspended solids, turbidity, and organic matter from industrial process water and wastewater streams.
FAQ
What factors determine the selection of activated carbon for industrial applications?
The selection of activated carbon depends on several key factors including the type of contaminants to be removed, required contact time, flow rates, and pH conditions. For organic compound removal, coconut shell activated carbon with high surface area and micro-porosity is preferred. For dechlorination applications, medium pore size distribution works best. The particle size should match the filtration system requirements to balance pressure drop and contact efficiency.
How does polyacrylamide dosage affect water treatment performance?
Polyacrylamide dosage significantly impacts treatment performance. Insufficient dosage may result in incomplete flocculation, while excessive dosage can cause re-stabilization of particles. The optimal dosage depends on water quality parameters including turbidity, suspended solids concentration, and particle size distribution. Jar testing is recommended to determine the ideal dosage for specific applications, typically ranging from 0.1-10 ppm depending on the treatment objective.
What are the storage requirements for citric acid in industrial facilities?
Citric acid should be stored in a cool, dry environment away from direct sunlight and moisture. The recommended storage temperature is below 30°C (86°F) to prevent caking. The product should be kept in tightly sealed containers to prevent moisture absorption, which can lead to lump formation. While citric acid is non-hazardous, proper ventilation should be maintained in storage areas. The shelf life is typically 2-3 years when stored under proper conditions.
How often should anthracite filter media be replaced in industrial systems?
The replacement frequency of anthracite filter media depends on several factors including influent water quality, filtration load, and backwash efficiency. Under normal operating conditions with proper maintenance, anthracite media can last 5-10 years. Regular monitoring of pressure drop and effluent quality helps determine when replacement is needed. Periodic media sampling and analysis can also provide insights into media condition and replacement timing.
