DOW BW30 PRO-2540 High-Efficiency Brackish Water RO Membrane | LEFILTER

Product Introduction

With the rapid development of commercial water purification and industrial water reuse, ordinary low-grade RO membranes often suffer from insufficient desalination rate, easy pollution and short service life when treating well water, surface water and slightly salty brackish water. To solve these pain points, DOW launched the upgraded BW30 PRO series, and the BW30 PRO-2540 is the core 2.5-inch compact commercial model in the lineup. As an upgraded version of the traditional BW30 membrane, it inherits classic aromatic polyamide thin-film composite technology and adds optimized anti-fouling and fast stabilization formulas, realizing higher water flux, more stable water quality and stronger pollution resistance.

LEFILTER provides 100% original imported DOW BW30 PRO-2540 brackish water RO membranes with complete factory test reports, authentic batch codes and dry membrane packaging. The product features a standard 2.5×40 inch size, an effective membrane area of 28 square feet, and a rated water yield of 1000 GPD. It is perfectly compatible with all mainstream 2.5-inch RO membrane housings in the market, supporting direct replacement and system upgrade without equipment modification. Relying on stable spot inventory and professional foreign trade service system, we support global small-batch trial orders and bulk wholesale, helping water treatment equipment manufacturers and engineering companies improve system operation efficiency.

Unique Product Advantages of BW30 PRO-2540

1. 99.7% Ultra-High Stable Desalination Performance

Compared with ordinary commercial RO membranes with 99.2%–99.5% salt rejection, the BW30 PRO-2540 achieves a stable desalination rate of 99.7%. It can deeply remove calcium, magnesium, heavy metal ions, soluble salts and organic impurities in brackish water, effectively reducing water conductivity. The outlet water quality is stable and consistent, which fully meets the water standard for commercial pure water machines, industrial production water and boiler make-up water, avoiding water quality fluctuation caused by membrane performance attenuation.

2. PRO-Grade Enhanced Anti-Fouling Performance

This upgraded PRO model adopts an optimized membrane surface hydrophilic coating and a reasonable 34mil feed spacer structure, which significantly reduces the adhesion of organic pollutants, sediment and biological slime. Compared with ordinary BW membranes, it is not easy to block during long-term operation in complex raw water such as well water and river water. The pollution resistance is greatly improved, effectively extending the service cycle and reducing the frequency of chemical cleaning.

3. Ultra-Wide pH Cleaning Tolerance (pH 1–13)

One of the biggest highlights of BW30 PRO-2540 is its ultra-wide cleaning pH range. It can withstand strong acid and strong alkali cleaning from pH 1 to pH 13, which is far superior to ordinary membranes with a narrow cleaning range. Users can use efficient chemical agents to thoroughly clean scaling, microbial pollution and organic fouling without damaging the membrane layer. The performance can be fully restored after cleaning, greatly reducing operation and maintenance costs.

4. Dry Membrane Design & Fast Performance Stabilization

The BW30 PRO-2540 adopts dry membrane preservation technology without liquid preservative. It has a long storage life, convenient international transportation and no leakage risk. Different from traditional wet membranes that require a long running-in period, this upgraded dry membrane can quickly stabilize water flux and desalination rate after installation, realizing fast commissioning and stable water supply, which is very suitable for global engineering project installation and after-sales replacement.

5. Low Pressure Operation & Energy Saving

Designed for commercial low and medium pressure systems, the BW30 PRO-2540 can maintain high water yield and high desalination rate under relatively low operating pressure. It effectively reduces pump load and system power consumption, bringing long-term energy-saving benefits for commercial water plants, factory water rooms and community water supply systems.

Applicable Water Quality & Industry Scenarios

The BW30 PRO-2540 is specially designed for brackish water with TDS ≤5000ppm, and performs best in raw water with TDS between 500–2000ppm. It is widely used in multiple industries and scenarios: commercial pure water equipment and community centralized water supply systems; industrial boiler feed water, electronic ultra-pure water pretreatment, food and beverage production water purification; underground well water, mountain spring water and river surface water deep purification; light industrial circulating water reuse and low-salinity wastewater desalination treatment. It is an all-round high-performance commercial membrane for daily and industrial water purification.

FAQs for DOW BW30 PRO-2540 Brackish Water RO Membrane

Q1: What does BW mean? What is the difference between BW and SW membrane?

A1: BW refers to Brackish Water, used for low-TDS tap water, well water and river water. SW is seawater membrane for high-salinity seawater. BW30 PRO-2540 cannot be used for seawater desalination, but performs better in commercial and industrial brackish water purification.

Q2: What is the desalination rate and filtration accuracy of BW30 PRO-2540?

A2: It owns a stabilized salt rejection rate of 99.7% and a pore size of 0.0001–0.001μm, which can accurately filter fine impurities, soluble salts, bacteria and organic pollutants in brackish water to produce high-purity pure water.

Q3: What are the advantages of the PRO version compared with ordinary BW membranes?

A3: The PRO upgraded version has higher desalination rate, stronger anti-fouling ability, wider pH cleaning range (1–13), faster performance stabilization and longer service life, more suitable for long-term continuous commercial operation.

Q4: What water quality is BW30 PRO-2540 suitable for?

A4: It is ideal for brackish water with TDS below 5000ppm, including tap water, underground well water, spring water and surface water, widely used in commercial and industrial pure water preparation projects.

Q5: What is the working temperature range of this membrane element?

A5: The stable operating temperature range is 5°C–45°C, with 25°C as the standard test temperature, adapting to most indoor and outdoor commercial water treatment working environments.

Q6: Is BW30 PRO-2540 easy to clean and maintain?

A6: Yes. It supports ultra-wide pH 1–13 acid and alkali cleaning, which can thoroughly remove various fouling. The membrane performance can be well restored after cleaning, with low maintenance cost and long service cycle.

Q7: What supporting services can LEFILTER provide?

A7: LEFILTER provides original product certification, free model selection, fast delivery, installation guidance, cleaning parameter suggestions and lifelong remote after-sales technical support for all BW30 PRO-2540 membrane users.
