Water Treatment Optimization
Industrial Water
Enhanced Treatment Performance
Rapid microbiological monitoring enables water treatment service providers to optimize industrial water systems based on actual microbial conditions rather than delayed laboratory feedback or indirect chemical indicators.
This allows engineering firms to continuously tune treatment strategies, across cooling, process, and utility water systems, ensuring that biocide programs, filtration regimes, and system conditioning measures are aligned with real biological demand. The result is more stable system performance, improved treatment efficiency, and higher service value delivered to industrial customers.
Challenges in Treatment Optimization
Effective water treatment optimization depends on timely, high-resolution system data that reflects actual microbial conditions.
In practice, service providers must make dosing and operational decisions under significant uncertainty due to delays and limitations in conventional monitoring methods. This reduces the responsiveness and precision of treatment programs and limits the ability to validate performance under real operating conditions.
- Culture-based microbiology introduces long reporting delays (typically 24–72+ hours), limiting the ability to adjust treatment programs in real time
- Standard microbiological methods fail to detect viable but non-culturable (VBNC) organisms, leading to incomplete system diagnostics and underestimated risk profiles
- Treatment optimization is often based on indirect indicators (e.g. conductivity, ORP, ATP trends), which do not provide direct quantification of microbial load
- Infrequent sampling schedules and site variability reduce the resolution of system diagnostics, creating gaps in understanding dynamic microbial behavior
- Delayed feedback on biocide performance limits the ability to validate treatment efficacy during ongoing operational conditions
These constraints reduce the precision of water treatment optimization services and often result in conservative dosing strategies or delayed corrective actions.
How We Help
Integrating Rapid Microbiological Data into Optimization Services
Integrating rapid microbiological monitoring into professional water treatment services enables a shift from periodic assessment to continuous, data-driven optimization. This approach embeds microbiological intelligence directly into service workflows, improving both responsiveness and decision quality.
1
System Assessment and Optimization Framework Definition
The water system is evaluated to define treatment objectives, critical control points, and existing monitoring and dosing strategies across relevant industrial water circuits.
2
Baseline Microbiological Profiling
Rapid single-cell analysis is used to establish a quantitative microbial baseline across system zones, providing a reference for normal operating conditions and early deviation detection.
3
Integration into Service Monitoring Programs
Rapid microbiological testing is incorporated into routine service activities, enabling significantly reduced time-to-result compared to traditional laboratory-based workflows.
4
Continuous Treatment Optimization and Feedback Control
Microbial data is used to dynamically adjust biocide dosing, cleaning strategies, filtration performance, and conditioning programs, enabling a closed-loop optimization model within service delivery.

Frequently Asked Questions
Here are some common questions about the test method, instrumentation and user requirements.
rqmicro combines three core technologies in a single workflow:
- Microbiological Assays detection and quantification of microorganisms including immunoassays for the selective quantification of target bacteria.
- Microfluidic cartridge technology with integrated immunomagnetic separation (IMS) for automated sample processing.
- Flow Cytometry for rapid detection and quantification of bacteria, including viability assessment.
This integrated approach enables rapid microbiological testing without the need for lengthy cultivation steps.
Single-use cartridges provide several advantages:
- Ensure standardized workflows
- Reduce maintenance requirements
- Minimize the risk of cross-contamination
- Eliminate complex cleaning procedures
- Enable operation by non-specialist users
The cartridge-based design supports both laboratory and field applications.
The rqmicro platform is designed for the detection and quantification of total bioburden and also specific bacteria. Depending on the assay, users can analyze:
- Total viable bacteria (Intact Cell Count)
- Total bacteria (Total Cell Count)
- Legionella (L.p. SG 1, L.p. SG 1-15 and Legionella spp.)
- E. coli (incl. Big 6 and O157)
Traditional culture methods only detect microorganisms that grow on agar plates. Many bacteria can remain viable but fail to form colonies under cultivation conditions.
rqmicro uses cultivation-independent flow cytometry, allowing the detection of viable cells regardless of their ability to grow on culture media. This provides faster results and a more complete picture of microbial contamination.
Flow cytometry is a laser-based analytical method that measures individual cells suspended in a fluid stream.
As cells pass through the laser beam, fluorescent signals are generated and detected by the instrument. Thousands of cells can be analyzed every second, enabling rapid and highly sensitive microbiological testing.
rqmicro uses fluorescence-based flow cytometry together with viability staining. Fluorescent dyes interact differently with live and dead cells based on membrane integrity and physiological status.
The instrument analyzes these fluorescence patterns to distinguish viable cells from non-viable cells, providing rapid live/dead information within the measurement process.
Viability information helps users:
- Assess microbiological risk more accurately
- Evaluate treatment effectiveness
- Detect bacteria that may be missed by culture methods
- Monitor changes in water systems in near real time
This enables faster operational decisions and improved process control.
VBNC stands for Viable But Non-Culturable.
These bacteria are alive and may remain metabolically active, but they do not grow on standard culture media. As a result, conventional cultivation methods can underestimate the true microbial load.
Flow cytometry can detect these cells, allowing a more comprehensive assessment of water quality and microbiological risk.
qmicro.COUNT is designed for routine operation with minimal training.
Users do not need to be flow cytometry experts. The cartridge-based workflow and automated analysis reduce operator dependency and simplify routine testing.
