FILTERSORB® SCB

Integrated Scale, Corrosion and Biofouling Control

Integrated Water Protection

Control scale, corrosion and biofouling with one integrated media

FILTERSORB® SCB is a factory-prepared water-treatment media combining three Watch Water® technologies for broader protection of plumbing, equipment and connected water systems.

Developed by Watch Water® GmbH in Mannheim, FILTERSORB® SCB combines FILTERSORB® SP3 for salt-free scale prevention, CorrTrapp® for corrosion-control support and AQUARedox® for redox-based contaminant and biofouling management. The ready-to-use formulation is designed for continuous upflow operation without salt regeneration, chemical dosing, routine backwashing or an electrical control valve. It can be applied in residential, commercial, municipal and industrial systems using city water, well water, hot water and selected process-water sources[cite: 3].

Three technologies. One media. Complete system protection[cite: 3].

75% scale prevention. 12.5% corrosion control. 12.5% redox protection[cite: 3].

FILTERSORB SCB Introduction

One integrated media
for multiple water systems

FILTERSORB® SCB is designed for applications requiring simultaneous scale prevention, corrosion-control support and management of conditions that contribute to biofouling[cite: 3].

Residential POU and POE Systems

Suitable for point-of-use and whole-house systems serving cold- and hot-water installations[cite: 3].

Hotels and Commercial Buildings

Protects plumbing, water heaters and connected equipment in hotels, colleges, universities and multistorey buildings[cite: 3].

Municipal Water Systems

Supports scale, corrosion and biofouling management in appropriately designed municipal installations[cite: 3].

Industrial Process Water

Suitable for industrial water systems, manufacturing equipment and process-water applications[cite: 3].

Heating and Cooling Water

Helps protect heating systems, cooling equipment and heat exchangers from mineral deposits and corrosion[cite: 3].

UF and RO Pretreatment

Can be used as feedwater conditioning before ultrafiltration and reverse-osmosis systems, subject to complete water analysis[cite: 3].

Four system benefits working together in one media

Salt-Free Nucleation Assisted Crystallization

The SP3 component transforms carbonate hardness into stable calcium-carbonate microcrystals with a reduced tendency to form deposits on plumbing and equipment[cite: 3].

Protection for Pipes and Connected Equipment

The magnesium-based CorrTrapp® component is designed to support less aggressive water conditions and reduce corrosion risk in suitable applications[cite: 3].

Redox-Based Surface and Water Protection

Zinc-coated and copper-coated activated-carbon components create electrochemical redox conditions intended to support organic-contaminant reduction and biofouling management[cite: 3].

No Salt Regeneration or Brine Wastewater

The recommended upflow system requires no salt, routine regeneration, electrical valve head or conventional regeneration wastewater[cite: 3].

Science &
Technology

FILTERSORB® SCB combines complementary physical, mineral and electrochemical processes in one factory-prepared media formulation[cite: 3].

  • Nucleation Assisted Crystallization – FILTERSORB® SP3 provides active nucleation sites that transform dissolved carbonate hardness into stable calcium-carbonate microcrystals[cite: 3].
  • Magnesium-Based Corrosion Control – CorrTrapp® is designed to influence the treated-water environment in a manner that supports corrosion protection for pipes and connected equipment[cite: 3].
  • Electrochemical Redox Activity – AQUARedox® combines zinc-coated and copper-coated activated carbon to create electrochemical oxidation-reduction conditions at the media surface[cite: 3].
  • Continuous Upflow Contact – Upflow operation supports water distribution and contact across the mixed-media bed without conventional regeneration backwashing[cite: 3].

Frequently
Asked Questions

Find answers about FILTERSORB® SCB, its three-media formulation, system design, operation and maintenance[cite: 3].

Contact Support
What is FILTERSORB® SCB?
FILTERSORB® SCB is a factory-prepared media combining scale prevention, corrosion-control support and redox-based biofouling management[cite: 3].
What does “SCB” represent?
SCB represents Scale, Corrosion and Biofouling—the three primary water-system challenges addressed by the formulation[cite: 3].
What is the FILTERSORB® SCB formulation?
It contains 75% FILTERSORB® SP3, 12.5% CorrTrapp® and 12.5% AQUARedox®[cite: 3].
How does FILTERSORB® SP3 prevent scale?
SP3 uses Nucleation Assisted Crystallization to transform dissolved carbonate hardness into stable calcium-carbonate microcrystals[cite: 3].
How does CorrTrapp® support corrosion control?
CorrTrapp® is a magnesium-based technology designed to promote water conditions that support corrosion protection[cite: 3].
How does AQUARedox® work?
AQUARedox® uses zinc-coated and copper-coated activated carbon to establish electrochemical oxidation-reduction conditions at the media surface[cite: 3].
Is FILTERSORB® SCB a water softener?
No[cite: 3]. It is a water-conditioning and protection media[cite: 3]. It does not provide conventional zero-hardness water[cite: 3].
Does it remove calcium and magnesium?
The SP3 component does not remove these minerals through ion exchange[cite: 3]. It alters the crystallization behavior of carbonate hardness[cite: 3].
Does it add sodium?
No salt-based ion exchange is used, so sodium is not intentionally added as a hardness replacement[cite: 3].
Does it require salt?
No salt-regeneration cycle is required[cite: 3].
Does it require electricity?
The basic upflow treatment vessel does not require an electrical regeneration valve[cite: 3]. Pumps or monitoring equipment may still require power[cite: 3].
Does it require backwashing?
The brochure specifies upflow operation without routine backwashing[cite: 3]. Pretreatment equipment may have separate backwashing requirements[cite: 3].
Does it produce wastewater?
It does not generate conventional salt-regeneration brine[cite: 3]. Commissioning, flushing or pretreatment maintenance may generate wastewater[cite: 3].
Can FILTERSORB® SCB eliminate bacteria?
No[cite: 3]. The brochure disclaimer states that the media does not eliminate bacteria[cite: 3]. Appropriate disinfection is required for unsafe or unknown-quality water[cite: 3].
Can it control biofilm?
AQUARedox® is positioned for biofouling management[cite: 3]. Any claim involving specific microorganism reduction must be supported by suitable challenge testing and regulatory authorization[cite: 3].
Can it remove heavy metals and emerging contaminants?
The brochure describes broad contaminant-reduction capabilities[cite: 3]. Specific removal percentages, capacities and service life must be confirmed under defined water conditions[cite: 3].
Is it suitable for city water?
Yes, subject to chlorine concentration, water chemistry, flow and the complete system design[cite: 3].
Is it suitable for well water?
It may be suitable after testing[cite: 3]. Pretreatment may be required for iron, manganese, sediment, hydrogen sulfide or microbiological contamination[cite: 3].
Can it be used with hot water?
The brochure specifies a maximum operating temperature of 80°C/176°F[cite: 3].
What is the operating pH range?
The stated operating pH range is 6.0–9.5[cite: 3].
How much media is required?
The brochure uses a preliminary guideline of 4 L of media for 1,000 L/h of design flow[cite: 3].
What vessel size is required?
The brochure recommends a pressure-vessel volume equal to approximately four times the SCB media volume[cite: 3].
Why is upflow operation required?
Upflow operation supports water distribution, contact and controlled movement of the mixed media[cite: 3].
How long does the media last?
The brochure states a typical service life of 3–5 years, depending on water quality and operating conditions[cite: 3].
Is FILTERSORB® SCB maintenance-free?
No[cite: 3]. It is low maintenance, but inspection, water testing, pretreatment servicing and eventual media replacement are still required[cite: 3].
Can it be used before reverse osmosis?
It is presented as an RO-feedwater treatment option[cite: 3]. Suitability must be confirmed against membrane requirements and complete feedwater chemistry[cite: 3].
Can it be used before ultrafiltration?
Yes, where the treatment objectives and influent conditions are compatible with the UF system[cite: 3].
Is professional installation recommended?
Yes[cite: 3]. Correct media quantity, vessel sizing, upflow distribution and commissioning are essential for reliable performance[cite: 3].
