RO System Optimization Audits from ALSI

Reverse osmosis systems are sensitive to fouling, scaling, and operating imbalances that develop over time. As conditions shift, systems often experience reduced performance, higher operating costs, and increased maintenance demands.

ALSI works directly with your team onsite to evaluate system performance, identify issues early, and provide clear, actionable recommendations to restore efficiency and maintain reliable operation. Click Here to Contact Us and Schedule Your System Audit 

What ALSI Evaluates During an Optimization Audit

During an optimization audit, ALSI performs a detailed, on-site evaluation of the RO system to verify operation against OEM design specifications and identify performance gaps.

The audit includes:

1. Membrane Performance & Operating Conditions
   Verification of membrane vessel operation, review of pressure differentials, and identification of fouling or scaling conditions impacting permeate quality and flow
2. System Performance & Operating Data
   Recording and analysis of key parameters such as flow rate, pressure, and system recovery to evaluate performance relative to design conditions
3. Instrumentation & Controls
   Calibration of instruments where possible and validation of system readings to ensure accurate monitoring and control
4. Filtration & Pretreatment Systems
   Inspection of cartridge filters and upstream components, with replacement of owner-provided filters as needed to maintain proper system operation
5. Chemical Usage & Dosing Systems
   Documentation of chemical consumption, evaluation of dosing effectiveness, and identification of inefficiencies impacting performance and operating cost
6. System Condition & Maintenance Needs
   Identification of abnormal operating conditions, worn components, or maintenance gaps, along with recommendations for service kits, cleaning, or replacement parts

ALSI records system performance data, works directly with plant personnel to address active issues during the visit, and provides a written system status report with clear maintenance and optimization recommendations.

Performance Optimization & Recommendations

ALSI evaluates system performance against OEM design conditions by reviewing key parameters such as flow rate, pressure, recovery, and chemical consumption to identify efficiency losses.

Our audits focus on the primary drivers of performance; flow rate, energy consumption, and chemical usage, which often reveal issues like fouled membranes, dirty filters, or improper settings.

ALSI provides targeted recommendations to restore performance, including adjustments to dosing, calibration, maintenance, and cleaning intervals. These corrections help stabilize operation, reduce costs, and extend membrane life.

What Comes Next?

Following the onsite visit, ALSI provides a structured system review that gives your team clear visibility into system condition and performance.

Each audit includes:

• Documented system performance data collected during the visit
• Identification of operating issues and performance gaps
• Clear maintenance and optimization recommendations
• Guidance on required spare parts or service kits
• Recommendations for membrane cleaning, cartridge replacement, and chemical adjustments

ALSI works directly with operators and maintenance personnel during the assessment to review system performance, discuss findings, and ensure recommendations are clearly understood and actionable. This hands-on approach allows your team to take immediate steps to improve system reliability and maintain consistent performance.
