With nearly 800 million people suffering from a scarce supply of clean water worldwide, our advanced membrane filtration is helping municipalities to purify their water supplies. Our technologies are made to comply with the Safe Drinking Water Act and World Health Organization guidelines, and we continue to innovate for the changing needs of tomorrow. Our cost-effective ultrafiltration and reverse osmosis systems make surface water safe to source by removing turbidity, suspended solids, bacteria and viruses. They also provide a positive barrier to contaminents that conventional media filtration cannot guarantee.
Municipalities worldwide are faced with wastewater challenges due to population growth, changing regulations, failing infrastructure or outdated technology. Our membrane bioreactor modules and systems provide reliable, energy-efficient performance to meet the necessary demands for water discharge and reuse, including tertiary treatment. Effluents of our wastewater treatment systems comply with strict discharge limits, as well as water reuse targets. Koch Separation Solutions filtration is currently a key part of the largest wastewater reuse effort in the Southern Hemisphere, the Aquapolo Ambiental project in São Paulo, Brazil.
MBR technology produces reuse quality water consistent with Title 22 for irrigation and other uses. Existing wastewater treatment systems can add our UF systems to produce the same quality of water. Further addition of our RO or NF technology can polish residual organics and TDS for high-quality reuse consistent with indirect or direct potable reuse systems.
Per- and polyfluoroalkyl substances (PFAS), including PFOA, PFOS, and other compounds, have been identified as emerging contaminants of concern for both drinking water supplies and wastewater discharge. PFAS-related regulations and guidance are becoming increasingly focused and stringent. Our RO and ion exchange technologies are ideal for removing many of these chemicals from water to reduce detectable levels.
Our filtration and separation solutions for desalination operations on naturally occurring water sources function by removing both suspended and dissolved solids to as low as ultra-pure levels, where required. These methods significantly reduce the waste of water, heat, energy, labor, and cleaning chemicals as compared with conventional technologies, and production quality is improved at lower costs.
When the objective is to create non-potable reuse water, often various unit operations will be required to remove TSS and/or TDS.
