As global water scarcity intensifies, wastewater reuse has become an effective solution to address the shortage of freshwater resources. The project of Singapore’s NEWater, with its advanced membrane treatment technology, has achieved high-quality reclaimed water and set a successful example for the global water treatment industry.
While NEWater relies primarily on physical filtration and UV disinfection, chemical disinfectants remain a key element in ensuring water safety in most wastewater reuse projects worldwide. This is especially true in the Middle East, where chemical disinfection remains a vital part of water treatment systems.
The Central Role of Disinfectants in Wastewater Reuse
Although NEWater adopts ultraviolet (UV) disinfection, many wastewater reuse facilities still depend on chemical disinfectants to ensure water safety and prevent secondary contamination, particularly during water transport and storage.
Below are some of the most commonly used disinfectants in such projects:
Sodium Hypochlorite (NaOCI):
· Kills bacteria, viruses, and algae effectively
· Widely used in industrial and municipal systems
· More cost-effective than UV in large-scale projects
Chlorine Dioxide (ClO₂):
· Powerful and fast-acting
· Removes biofilm and prevents system fouling
· Doesn’t create harmful byproducts like THMs
· Ideal for seawater desalination and wastewater reuse
Hydrogen Peroxide (H₂O₂):
· Advanced oxidizer
· Works well with UV for deep disinfection
· Effective in removing trace pollutants like pharmaceuticals and metals
Wastewater Reuse in the Middle East
While Singapore’s NEWater project offers valuable insights into global wastewater reuse, countries in the Middle East—where water resources are minimal—rely heavily on wastewater reuse and seawater desalination as key strategies for water resource management. Nations like Saudi Arabia and the United Arab Emirates are increasing investments in water reuse infrastructure. Organizations such as the Saudi Water Partnership Company (SWPC) and the Abu Dhabi Water and Electricity Authority (ADWEA) actively promote related projects.
Due to high ambient temperatures and the extensive length of water pipelines, wastewater reuse in the Middle East tends to rely more heavily on chemical disinfectants to maintain long-term water quality. Seawater desalination plants also frequently use chlorine dioxide and sodium hypochlorite to disinfect pipelines and prevent biofouling.
Unlike Singapore’s NEWater, most wastewater treatment projects in the Middle East continue to use a combination of chemical precipitation, disinfection, and membrane filtration. Linp Chemical provides high-performance chemicals that help improve water treatment efficiency, extend equipment lifespan, and ensure that final water quality meets international standards. Even though NEWater uses UV disinfection, chemical disinfectants remain essential in Middle Eastern distribution networks, making Linp Chemical’s sodium hypochlorite (NaClO) and chlorine dioxide (ClO₂) ideal choices.
