Advanced wastewater solutions for sustainable water management

Reusing municipal wastewater is a necessary way to address the world’s growing water demand. At IDE, we offer advanced solutions that comply with and exceed environmental and regulatory requirements.

TTRO (Tertiary Treatment Reverse Osmosis)

Tertiary Treatment RO refers to the process of using reverse osmosis (RO) technology in the tertiary treatment stage of wastewater treatment.

Tertiary treatment is the final stage of wastewater treatment, following primary and secondary treatment. Its primary objective is to remove any remaining stubborn contaminants from the water that were not removed by the previous stages, before it is discharged into the environment or reused.

Tertiary treatment usually involves advanced treatment processes such as filtration, disinfection, membrane filtration, reverse osmosis, activated carbon adsorption, and chemical precipitation. These processes remove any remaining suspended solids, organic matter, nutrients, and pathogens from the water.

Tertiary treatment using RO technology has become increasingly popular as a method of producing high-quality treated water for reuse. It can effectively remove a wide range of contaminants from the water, including pathogens, heavy metals, and organic pollutants. RO technology is also known for its efficiency and low energy consumption, making it a cost-effective option for producing high-quality water.

Tertiary treatment is an important part of wastewater treatment as it helps to protect public health and the environment by ensuring that treated water is safe and free from contaminants.



FAT (Fully Advanced Treatment)

FAT is the conventional solution for municipal wastewater reuse facilities.

The treatment, which is common in the United States, uses an additional step of treatment to the TTRO and includes three stages; UF/MF, standard multi-stage RO and UV/AOP. UV AOP, the process of using ultraviolet light with an oxidant to break down environmental contaminants in water, is an essential part of the potable reuse treatment scheme.

Drinking water sources we rely on every day are increasingly contaminated with chemicals. Several of these contaminants are harmful or carcinogenic and must be removed for the water to be considered potable.

FAT produces water that meets the strictest regulations for water reuse. It includes a 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.

IDE offers these two FAT solutions:


FAT with RO

A modular traditional three stages RO with standard recovery rates.


FAT with PFRO which delivers:
