LOONG & NORTHERN CHINA'S LARGEST SEAWATER DESALINATION PROJECT


The water treatment industry plays a vital role globally, especially in regions with scarce freshwater resources. Seawater desalination is not only a crucial guarantee for domestic water supply but also an important source of industrial water.
However, in actual operation, seawater desalination projects face challenges such as fluctuating water quality and frequent equipment maintenance, urgently requiring innovative filtration solutions to improve system reliability and efficiency.

LOONG Filter stepped in at this critical moment, designing a series of solutions to address the project's problems and contributing to the region's domestic and industrial water supply.


I. Customer Background and Core Filtration Challenges


This project is one of the largest seawater desalination projects in Northern China in terms of annual processing capacity, with a designed capacity of 150,000 tons, aiming to provide a stable freshwater resource for local industry and domestic use. However, the project encountered a serious problem during operation: extremely large fluctuations in raw water quality led to frequent clogging of the reverse osmosis (RO) membrane.

Challenges Customer Facing


• Frequent Reverse Osmosis (RO) Membrane Clogging:

The RO system requires disassembly and cleaning dozens of times annually, increasing maintenance costs and impacting overall water production efficiency.


 Inadequate Design:

The project lacked a security filter in its initial planning, and the extremely limited space available for equipment installation further exacerbated system instability and operational difficulties.







II. LOONG’s Solution to Help Out

Solutions


Addressing these pain points, LOONG Filter implemented a centralized piping solution, utilizing a systematic design and innovative engineering approach to fully leverage the customer's limited space. This solution not only resolved space constraints but also significantly reduced the risk of RO membrane fouling by optimizing the filtration process.


 Northern China's Largest Seawater Desalination Security Filter: 

With a full-load water production capacity of 4000 cubic meters per hour, high-quality materials ensure durability even in harsh water conditions.

 Super Dirt-holding High-Flow PP Filter Cartridge:

High-Efficiency Filtration: 1.5 times flow rate reaches that of ordinary structures.

Long Lifespan: 3 times service life that of conventional high-flow filter cartridges.



III. Implementation Results: Improved water production efficiency and lifespan
