High Desalination Reverse Osmosis Membrane
Products Description
Optimized Total Cost of Ownership
Our membrane elements deliver exceptional overall water cost efficiency by fine-tuning energy consumption and boosting system throughput. This design cuts down both operational energy expenses and long-term maintenance costs, creating a more economical solution for large-scale water treatment projects.
Superior Long-Term Durability
Engineered with advanced material technology, our membranes offer outstanding mechanical and chemical durability, ensuring consistent, reliable performance over an extended service life. This stability eliminates unexpected downtime and performance degradation, guaranteeing uninterrupted, high-quality water output.
Extended Shelf Life & Enhanced Sustainability
Compared to traditional wet-pack RO membranes, our dry-pack design features a longer storage window and extended warranty coverage, while also reducing the environmental impact throughout the product lifecycle. This sustainable design minimizes waste and lowers the carbon footprint of membrane production and transportation.
Product Features
- Significant Cost Savings for Customers: The product has high water flux and stable high desalination performance. For enterprises, it can improve water treatment efficiency, reduce the number of membrane elements required for the water treatment system, and further reduce the initial investment cost of the system. At the same time, the product has a long service life and low maintenance frequency, which can reduce the operation and maintenance cost of the enterprise in the later period.
-
Guarantee the Safety and Stability of Water Quality: The salt rejection rate of the product is as high as 99.5% (minimum 99.0%), which can effectively intercept various salt ions and harmful impurities in the water, ensuring that the effluent water quality meets the national drinking water standard and industrial pure water/ultrapure water standard, and guaranteeing the safety and stability of production and living water use.
-
Improve Production Efficiency: The product adopts multi-page/short-page welding technology and optimized diamond-shaped flow channel design, which eliminates dead zones and increases effective membrane area, making the water treatment efficiency significantly higher than that of ordinary reverse osmosis membranes. It can meet the large-scale water treatment needs of enterprises and avoid the impact of water treatment problems on production progress.
-
Preferential Price Policy: For customers with large orders, we provide preferential price policies. For a single order of more than 100 membrane elements, we can give a 5% discount; for a single order of more than 200 membrane elements, we can give a 8% discount, and provide free transportation services, further reducing the purchase cost of customers.
Application Fields
The ROA-8040 series high desalination reverse osmosis membrane is widely used in various high-standard water treatment scenarios, and its application fields cover civil, industrial and other fields. In the civil field, it is mainly used for tap water upgrading and purification, which can remove harmful substances such as salt ions, heavy metals and organic matter in tap water, improve the taste and safety of tap water, and provide clean drinking water for residents, hotels, catering and other places. In the industrial field, it is widely used in the preparation of industrial pure water and ultrapure water in electronics, pharmaceutical, chemical, semiconductor and other industries. The high desalination performance of the product can meet the high water quality requirements of industrial production processes, ensure the stability of product quality and improve production efficiency.
In addition to the above main application fields, the ROA-8040 series high desalination reverse osmosis membrane also has a wide range of other applications. It can be used in the water treatment of high-salt water in coastal areas, desalinate seawater and brackish water to meet the water demand of coastal residents and enterprises; it can be used in the preparation of pure water for medical institutions, providing high-quality pure water for medical equipment cleaning, drug preparation and other links; it can also be used in the water treatment of food processing industry, ensuring the safety and hygiene of food production water and meeting the national food safety standards.
Especially in the field of seawater desalination, the ROA-8040 series membrane can effectively desalinate seawater with high salt content, reduce the salt content in water to the standard of drinking water or industrial water, and provide an effective solution for solving the shortage of fresh water resources in coastal areas.
International Certification Advantage: With CE, FDA, ISO9001 and other international authoritative certifications, the product can freely enter the global high-end water treatment market, especially the European and North American markets with strict quality requirements. It saves customers the time and cost of certification approval for market access, and enhances the credibility and market competitiveness of customers' projects.
Packing and Delivery
- In order to ensure that the product is not damaged during transportation, we adopt a three-layer packaging design: the inner layer is a moisture-proof plastic bag, which can prevent the membrane element from being damp; the middle layer is a shock-proof foam, which can reduce the impact of transportation vibration on the product; the outer layer is a hard carton, which has strong pressure-bearing capacity and can prevent the product from being crushed. For the packaging of large quantities of orders, we will use wooden pallets for reinforcement to ensure the safety of the product during transportation. In terms of transportation, we cooperate with well-known logistics companies (such as DHL, FedEx, SF Express) to provide fast and efficient transportation services. The delivery time is 3-5 working days for domestic orders and 7-15 working days for international orders. We will provide the logistics tracking number in time after delivery, so that customers can query the transportation status at any time.
