As the core facility for industrial pure water and ultrapure water production, reverse osmosis equipment relies heavily on the comprehensive strength of its manufacturer, which directly determines water stability, energy consumption and operation & maintenance costs. With nearly 20 years of dedication in the industry, DIEN Water Treatment ranks among the first-tier domestic RO equipment manufacturers through independently controlled full-chain technology, large-scale intelligent manufacturing and full-scenario service capabilities. We have become a benchmark brand for domestic substitution and solving industry pain points.
I. Independently Controlled Core Technology — Breaking Industry Technical Bottlenecks
As a national High-Tech Enterprise, DIEN Water Treatment has built an R&D team led by masters and doctors in membrane separation technology. Cooperating with top domestic universities and research institutes, we have established a complete intellectual property system covering membrane materials, structural design and system integration, holding nearly 90 patents and participating in the formulation of more than 20 national and industrial standards.
Aiming at the common pain points of traditional RO membranes — difficulty balancing salt rejection and flux, easy fouling and high energy consumption — we have developed an innovative branched monomer membrane modification technology. Our low-pressure RO membrane maintains a stable salt rejection rate of 99.7%, and high-end brackish water membrane reaches 99.8%, with flux increased by 15% and energy consumption reduced by 20%, achieving triple breakthroughs of high salt rejection, high flux and low energy consumption.
The integrated RO-EDI process achieves a desalination efficiency of 99.98%, with power consumption of only 0.8–1.2 kWh per ton of water and energy saving over 30%, thoroughly breaking international technological monopoly.

II. Full-Scenario Customization + Large-Scale Intelligent Manufacturing — Meeting Diverse Industrial Demands
Equipped with production bases, Class 100 dust-free workshops and fully automatic production lines, DIEN achieves an annual output of over 6,000 sets, forming a complete industrial chain layout integrating R&D, production, installation and after-sales service with remarkable cost and efficiency advantages.
Our equipment covers semiconductor, chemical, thermal power, pharmaceutical, agricultural, municipal and other full scenarios, with customized pure water systems ranging from 5t/h to 1000t/h. We provide ultrapure water solutions for semiconductor enterprises that precisely match wafer packaging standards; customized **Pretreatment + Double-Stage Reverse Osmosis + EDI + Mixed Bed** processes for thermal power plants to meet medium and high-pressure boiler water requirements.
Agriculture-dedicated RO equipment achieves a water saving rate of 30% and wastewater reuse rate of 95%, adapting to complex water quality such as high salinity and strong corrosion. All equipment undergoes strict water flow testing before delivery and passes authoritative certifications including ISO9001, CE and water approval documents. The service life of core membrane elements is extended to 8 years to ensure long-term stable operation.
III. Global Service Network + Intelligent O&M — Ensuring Worry-Free Full-Cycle Project Operation
DIEN has established more than 20 offices and service outlets nationwide covering major industrial cities. Supported by ERP and intelligent cloud monitoring systems, we realize rapid response and 24-hour emergency technical support.
We provide one-stop services including scheme design, installation & commissioning, old system upgrading, remote operation & maintenance, and 5-year warranty, forming a closed loop of strict quality control and after-sales support.
Our well-known clients include Hesheng Silicon Industry, Xiuzheng Pharmaceutical, Huawei and other leading enterprises. We have successfully launched multiple large-scale thousand-ton pure water projects, maintaining top-ranked customer satisfaction and market reputation in the industry.
DIEN Water Treatment builds its strength through technology, intelligent manufacturing and comprehensive services. From membrane material R&D to system integration, from single equipment to large-scale projects, we have formed irreplicable comprehensive competitiveness.
Against the backdrop of increasingly strict industrial water standards and upgrading demands for water saving and emission reduction, our high-cost-performance and high-stability reverse osmosis equipment has become the preferred solution for water treatment upgrading in various industries, continuously promoting domestic water treatment equipment toward higher development levels.
