Bangladesh 150 TPH Two-Stage Reverse Osmosis + EDI Water Treatment System for Boiler Water
As global water scarcity and water pollution grow more serious, high-purity water treatment technology has become key to industrial production and public well-being. Bangladesh has a large population and fast-developing industries, so its demand for high-quality water treatment systems is especially urgent. This article fully explains the 150TPH two-stage RO + EDI water treatment solution for the Bangladesh AL FATTAH project and provides practical references for similar projects.
1. Core Project Parameters: Build a Solid Base for Efficient Operation：
The Bangladesh AL FATTAH water treatment project sets precise parameters from the initial design stage to ensure long-term, stable and efficient system performance.
First, the project reaches a treatment capacity of 150 TPH (tons per hour). It easily meets large-scale industrial and centralized water supply needs.
Second, raw water has a TDS (Total Dissolved Solids) of 1555 mg/L, which contains certain amounts of dissolved salts and organic matter. We can only remove these impurities effectively with mature treatment processes.
In addition, the equipment uses a 380V, 50Hz, three-phase power design. It fully matches local power standards in Bangladesh and makes equipment operation more stable and safer.
2. Two-Stage RO + EDI Process: Dual Protection for High-Purity Water：
2.1 Two-Stage RO Technology: Deeply Remove Impurities：
RO (Reverse Osmosis) is one of the most popular water treatment technologies worldwide, and it plays a central role in this project.
First, the first-stage RO system performs preliminary purification on raw water. It uses high-pressure pumps to push water molecules through the RO membrane and traps salts, colloids, organic matter and microorganisms.
However, first-stage RO water still holds small amounts of residual impurities. So we continue to use the second-stage RO system for deep treatment. Second-stage RO uses higher-precision membrane elements that further remove trace ions and impurities and greatly improve water purity.
More importantly, second-stage RO provides stable and qualified inlet water for the downstream EDI system and lays a strong foundation for final ultra-pure water.
2.2 EDI Technology: Produce Ultra-Pure Water：
After two-stage RO, the EDI system continues deep desalination and finally produces ultra-pure water.
EDI combines ion-exchange resin with an electric field. It continuously absorbs and removes ions from water without stopping for regeneration.
Compared with traditional ion-exchange equipment, EDI needs no chemical regeneration. It cuts operating costs and reduces pollutant discharge, and it fully follows green and eco-friendly principles.
With the two-stage RO + EDI combined process, the system steadily delivers ultra-pure water that meets strict requirements for boilers and high-precision industries.
3. Project Value: Support Sustainable Water Development in Bangladesh：
The Bangladesh AL FATTAH 150TPH two-stage RO + EDI project not only supplies stable, high-quality water but also promotes local sustainable water development.
Economically, the project satisfies boiler and process water demands for factories. It reduces equipment failures, lowers production costs and directly supports stable local industrial growth.
Socially, the project improves water use efficiency and water safety. It provides more reliable water support for local residents and businesses.
4. Reference for Similar Projects: Promote Wide Use of Advanced Water Treatment Technologies：
The successful design and implementation of the Bangladesh AL FATTAH project offer valuable experience for large-scale water treatment projects in developing countries.
First, the project fully adapts to local water quality, power standards and actual water needs. It uses a customized solution with strong practicality.
Second, the project proves the reliability and advantages of the two-stage RO + EDI process in large-scale ultra-pure water projects.
As global water pressure keeps rising, such efficient, energy-saving and eco-friendly technologies will win wider application. They will strongly support sustainable water development around the world.
