What issues should be paid attention to in the purchase of industrial reverse osmosis water treatment equipment?

In industrial production, high-quality water sources are crucial to ensuring product quality, protecting equipment life and meeting environmental protection requirements. As an efficient and reliable purification method, reverse osmosis water treatment equipment is widely used in many industries such as chemicals, electronics, medicines, food and beverages. However, the choice of industrial reverse osmosis water treatment equipment is not easy, and multiple factors need to be considered comprehensively to ensure its performance, efficiency and economic benefits. Jinzong Enterprise, which has more than 20 years of experience in the production, design and development of water treatment equipment, will explain in detail the purchasing guide for industrial reverse osmosis water treatment equipment.

1. Define water quality requirements and treatment goals

The primary task when purchasing industrial reverse osmosis water treatment equipment is to precisely grasp the quality requirements and treatment goals. This includes:

Source water quality analysis: Conduct a comprehensive inspection of the incoming water source to understand its chemical composition, ion concentration, turbidity microbial content, and other parameters, ensuring that the equipment design can specifically remove particular pollutants.

Discharge water quality standards: Clarify the specific water quality requirements of production process, such as conductivity, hardness, TOC (total organic carbon), microbial indicators, etc., to ensure that the water quality of the reverse osmosis's discharge meets or exceeds these standards.

Treatment volume requirements: Calculate the daily or hourly treatment volume of the equipment needed according to the production scale and water usage, ensuring that the equipment's water production capacity matches the actual demand.

2. Evaluation of equipment performance and technical parameters

Reverse Osmosis Membrane Elements: The membrane element is the core component of the osmosis equipment, and its performance directly affects the water purification effect. It is important to focus on factors such as the desalination rate, flux, chemical stability, anti-fouling ability of the membrane, and to select the appropriate material (such as polyamide composite membrane, cellulose acetate membrane, etc.) and model based on the characteristics of the water quality.

Recovery Rate and Energy Consumption: In industrial production, water and energy conservation are important considerations. Choosing equipment with high recovery rate can reduce concentrate discharge and lower operating costs; at the same time, pay attention to the equipment's energy consumption indicators, such as water energy consumption per ton (Wh/m³), and select equipment with a high energy efficiency ratio.

Pre-treatment and Post-treatment Systems: Based on the raw water quality, whether it is necessary to configure pre-treatment (such as multimedia filtration, activated carbon adsorption, softening, ultrafiltration, etc.) and post-treatmentsuch as UV disinfection, EDI electrodialysis, etc.) systems to ensure the stable operation of the reverse osmosis membrane and the compliance of the eff water quality.

3.Evaluation of Equipment Manufacturer and After-sales Service

Manufacturer Qualifications and Experience: Select equipment manufacturers with relevant industry qualifications extensive project experience, and a good market reputation to ensure the professionalism and reliability of the equipment's design, manufacturing, installation, and commissioning.

Customized Services: water demand often has its particularities. Excellent equipment suppliers should have the ability to provide personalized solutions, such as process optimization for complex water quality and non-standard design for specific space.

After-sales Service System: Examine the after-sales service network, response speed, maintenance capability, and spare parts supply of the equipment supplier to ensure that timely effective technical support and maintenance can be obtained when equipment malfunctions during operation. 

4. Economic Analysis and Return on Investment

Equipment Purchase Cost: Compare the quotations of different brands and models of equipment, considering their performance, quality, service life, and other factors, to conduct a cost-performance analysis.

Operating Cost: Calculate the energy consumption, chemical agent consumption, maintenance, and consumable replacement costs during the operation of the equipment, to assess the long-term operating costs.

Payback Period: Combine the equipment purchase cost and operating cost, as well as the potential benefits such as increased production efficiency, extended equipment life, and exemption from environmental fines due to improved water quality, to calculate the payback period and ensure the economic benefits of the project.

In summary, the selection of industrial reverse osmosis water treatment equipment needs to be comprehensively considered from multiple dimensions such as water quality requirements, equipment performance, manufacturer strength, and economy. Through rigorous analysis and comparison, we can choose the ideal equipment that not only meets the production needs but also maximizes economic benefits.
