IDE meets the diverse water treatment needs of municipalities around the world with state-of-the-art technologies and solutions.

Municipal water treatment requires reliable, efficient, and safe processes to ensure communities’ access to fresh drinking water.  IDE partners with municipalities around the world in smart, efficient, eco-friendly, and cost-effective ways.  IDE’s integrated solutions and unique expertise help manage and overcome important challenges in the dynamic municipal sector.


Municipalities around the world have to cope with increasing population and industrial growth, stricter regulations, and an ever-decreasing supply of freshwater due to climate change. They need partners who understand these issues and can work together on the development, construction, operation, and financing of innovative, economical, and sustainable municipal water treatment solutions.



  • Address needs related to infrastructure expansion and replacement
  • Effectively treat wastewater and redirect it for reuse
  • Adhere to policies and regulatory requirements
  • Create a sustainable and high-quality water supply
  • Meet the increased water demands of a growing population


IDE works with municipalities as an equipment supplier, turnkey project integrator or sub-contractor, depending on the customer’s needs. Possible models include joint ventures, strategic partnerships, Build-Operate-Transfer (BOT), Build-Operate-Own (BOO), Engineering-Procurement-Construction (EPC), Engineering-Procurement-Services/Support (EPS), Private Finance Initiative (PFI) and others. Within these frameworks, IDE accepts responsibility for building the project (including securing required financing), and then operating the facility under a long-term concession (ranging from 10-30 years) after which the plant is transferred to the customer.

From Drain to Drink: Discover IDE's Water Treatment Technologies for Municipalities

  • Tertiary Treatment

    Tertiary water treatment is the final stage of the multi-stage wastewater cleaning process. This third stage of treatment removes inorganic compounds, bacteria, viruses, and parasites. Removing these harmful substances makes the treated water safe to reuse, recycle, or release into the environment.



  • Microfiltration (MF)

    Microfiltration is a filtration process using a microporous media that retains the suspended solids of a fluid. The pore size of the membrane ranges from 0.1 to 1 microns. Microfiltration is different from reverse osmosis and nanofiltration in that it does not require pressure. It is often used as a pretreatment step in the production of drinking water and industrial water. It has excellent properties to eliminate suspended solids, bacteria and cysts.

  • Fully Advanced Treatment (FAT)

    FAT is the conventional solution for industrial and wastewater reuse facilities.

    The treatment includes three stages, UF/MF, Standard multi-stage RO, and UV/AOP, which produces water that meets the strictest regulations for water reuse. It includes dosage of chloramine, which helps control biofouling of the membranes but is also a precursor to the formation of disinfection byproducts such as NDMA – a dangerous organic contaminant and a suspected carcinogen.

  • Ultrafiltration (UF)

    Ultrafiltration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.

  • PFRO: Chloramine-Free Water Reuse Solution

    IDE’s Pulse Flow Reverse Osmosis (PFRO™) technology is completely chloramine-free. Contrary to standard RO systems that operate under continuous hydraulic and osmotic conditions, the PFRO™ process utilizes alternating hydraulic conditions, switching between dead-end production mode and flushing mode, during which brine is flushed out at high velocity.

    The constantly changing hydraulic conditions make it very hard for microorganisms to sustain themselves, thereby reducing the risk of biofouling and scaling. This allows the system to operate at very high flux rates (50% higher than normal), eliminating the risk of rapid increase in biofouling and resulting in overall CAPEX savings of about 20%.

    IDE’s proven and innovative PFRO™ solution for water reuse, can help municipalities power water resiliency, security and sustainability.
