HYDROSORB®

Advanced framework-based adsorber for complex water contaminants

Advanced Adsorption Technology

One advanced adsorber / A wider contaminant spectrum

HYDROSORB® is a high-performance adsorber combining activated carbon with Watch Water®’s proprietary FerroPhos surface treatment and framework-based adsorption technology.

HYDROSORB® is designed to capture selected organic compounds, metals, taste-and-odor substances and emerging contaminants from drinking water, industrial water and wastewater. Its granular activated-carbon base provides an extensive network of micro-, meso- and macropores. The FerroPhos coating and described COF/MOF functionality introduce additional adsorption, complexation and redox-active sites. This multi-mechanism structure enables HYDROSORB® to target a broader range of contaminants than standard activated carbon alone. It can be installed in point-of-use, point-of-entry, commercial, municipal and industrial pressure-vessel systems using either upflow or downflow service.

Activated carbon + functional coating / Advanced adsorption performance

HYDROSORB Introduction

One adsorber.
Multiple water-treatment challenges.

HYDROSORB® can be integrated into residential, commercial, municipal and industrial treatment systems. Contaminant-specific testing is required to establish capacity, breakthrough behavior and regeneration suitability.

Drinking-Water Treatment

Point-of-use, point-of-entry, commercial and municipal adsorption systems.

PFAS and Emerging Contaminants

Adsorption treatment for selected PFAS, pharmaceuticals and personal-care compounds.

Industrial Wastewater Treatment

Treatment of selected organics, metals, solvents and industrial process contaminants.

Taste, Odor and VOC Control

Reduction of MIB, hydrogen sulfide, solvents and odor-causing organic compounds.

Heavy-Metal Treatment

Adsorption, complexation and redox-assisted capture of selected dissolved metals.

Environmental Remediation

Treatment of contaminated groundwater, landfill-impacted water and remediation streams.

Four treatment mechanisms engineered into one media

CP

Multi-scale pore adsorption

The activated-carbon base provides micro-, meso- and macropores for capturing organic compounds of different molecular sizes.

FC

Iron-assisted contaminant capture

Iron-containing surface sites can support electrostatic attraction, complexation, adsorption and redox reactions with selected metals and organic contaminants.

PB

Phosphorus-functionalized binding sites

The described FerroPhos treatment introduces functional sites intended to improve affinity for selected metals, nutrients and radioactive contaminants.

FX

COF/MOF-inspired surface functionality

The brochure describes covalent-organic and metal-organic framework functionality that creates tunable adsorption sites for selected emerging contaminants.

Multi-mechanism surface chemistry for advanced adsorption

HYDROSORB® combines physical adsorption, electrostatic attraction, surface complexation and redox-active interactions within one granular medium.

  • Physical Adsorption – Organic molecules are retained within the activated-carbon pore network through dispersion forces and surface interactions.
  • Electrostatic Attraction – Positively or negatively charged surface regions may attract oppositely charged contaminant species.
  • Surface Complexation – Iron- and phosphorus-containing functional sites can form surface complexes with selected dissolved metals.
  • Redox-Assisted Treatment – Zero-valent or ferrous iron sites may transform selected contaminants into less mobile or more readily adsorbed forms.

Regeneration Process & Steps

HYDROSORB® is designed to be regenerable using a 10% Instant Oxydes® solution following proper countercurrent contact protocols.

Step 1: Initial Rinse

Rinse the media with clean water to remove loose solids and prepare the bed for regeneration.

Step 2: Prepare Regenerant

Prepare Instant Oxydes® solution in a dedicated chemical-resistant tank using current product instructions and SDS.

Step 3: Countercurrent Contact

Introduce the regenerant opposite to the normal service-flow direction to improve media contact and reduce channeling.

Step 4: Contact Period

Allow approximately one hour for general applications or two hours for emerging contaminants.

Step 5: Final Rinse

Rinse thoroughly to remove residual oxidant, released contaminants and transformation by-products.

Step 6: Verify Before Service

Confirm acceptable pH, oxidant residual, turbidity, TOC and target concentrations before returning to service.

Contact Support
What is HYDROSORB®?
HYDROSORB® is a granular adsorber combining activated carbon with a proprietary FerroPhos treatment and described COF/MOF surface functionality.
How does HYDROSORB® work?
It combines physical adsorption, electrostatic attraction, surface complexation and redox-assisted interactions to capture selected water contaminants.
Which contaminants can HYDROSORB® address?
Potential applications include selected pesticides, pharmaceuticals, VOCs, chlorinated solvents, heavy metals, PFAS, taste-and-odor compounds and nutrient-related contaminants.
Can HYDROSORB® remove PFAS?
It is intended for PFAS adsorption, but performance varies substantially by compound. Short-chain PFAS generally break through faster than long-chain PFAS, so compound-specific testing is essential.
Can HYDROSORB® reduce fluoride, chloride and sulfate?
These anions are not reliably removed by ordinary activated carbon. Any performance claim requires verified capacity data demonstrating the role of the functional coating.
Can HYDROSORB® remove ammonia?
Possible performance depends on whether ammonia is present as NH₃ or NH₄⁺, along with pH, competing ions and the media’s verified ion-capture capacity.
Can it remove bacteria and microorganisms?
Adsorption or filtration may reduce some organisms, but HYDROSORB® should not be described as a validated disinfectant without organism-specific log-reduction testing.
Can HYDROSORB® operate in upflow and downflow systems?
Yes. Upflow is generally presented for smaller installations, while downflow systems are described for commercial, municipal and industrial applications.
How is the media regenerated?
The brochure describes regeneration using Instant Oxydes® solution, followed by thorough rinsing and water-quality verification.
How often should regeneration be performed?
Regeneration should be triggered by contaminant breakthrough, treated-water volume or declining performance. A fixed annual interval is not suitable for every application.
Can regenerated media recover its full original capacity?
This cannot be assumed. Regeneration efficiency depends on the contaminant, adsorption mechanism, oxidative stability and number of previous regeneration cycles.
Is HYDROSORB® suitable for drinking water?
Drinking-water use requires current certification, extractables testing, contaminant-specific performance data and confirmation that coating or regeneration residues remain within applicable limits.
