RO System Chemicals
Our products and services in the field of RO systems for industry
Reverse Osmosis (RO) systems use semi-permeable membranes to remove salts, ions, and suspended solids from water, serving applications from drinking water production to highly sensitive industrial processes.
The main challenges for RO systems are scaling, fouling, and microbial contamination, which can reduce production capacity, increase energy consumption, and shorten membrane life.
Using specialized chemicals such as antiscalants, membrane-compatible biocides, SDI reducers, and targeted cleaning agents—along with precise water quality monitoring—is an effective solution to ensure stable performance, minimize downtime, and extend membrane lifespan.
Antiscalants
Designed to prevent scale formation on membrane surfaces. The first generation of antiscalants entered the desalination industry in the 1970s and were mostly phosphonate-based. Today, advanced acrylic polymers and special copolymers are preferred for their higher efficiency. Their mechanisms include preventing crystal nucleation, altering crystal growth, and dispersing particles.
Biocides & SDI Reducers
Specialized RO biocides are formulated to control and eliminate microbial growth without damaging membranes. SDI (Silt Density Index) reduction is achieved through proper pretreatment and coagulants to prevent fouling. Together, these measures maintain system performance and minimize the need for frequent cleanings.
Cleaning Chemicals
Depending on the type of fouling (mineral, organic, or biological), alkaline, acidic, or enzymatic cleaners are used.
Potable Water Grade Chemicals
For systems producing drinking water, compliant with NSF/ANSI 60 standards.

FAQs
Everything you need to know, right here.
What types of chemicals are used in RO water treatment?
Industrial RO systems use several types of chemicals:
Antiscalants to prevent scale formation
Biocides to control bacterial growth and biofilm
Membrane cleaning chemicals for periodic removal of fouling and deposits
pH regulators to optimize feedwater conditions
When used correctly and regularly, these chemicals ensure stable system performance and extend membrane life.
Why are chemicals necessary in RO systems?
Chemicals are essential to prevent scaling, fouling, and microbial growth on membranes. Without proper treatment, membrane performance declines, pressure drop increases, and maintenance and replacement costs rise significantly.
When should membrane cleaning (CIP) be performed?
Chemical cleaning is usually required when the pressure drop (ΔP) across the membranes increases by more than 10–15%, or when product water flow and quality begin to decline.
What is the main advantage of using RO chemicals regularly?
The key benefits include:
Extended membrane life
Reduced maintenance and repair costs
Consistent water quality and production capacity
Prevention of unexpected process downtime
