RO Antiscalant – Genesys CAS (Seawater Grade)
Genesys CAS is a high-performance RO antiscalant anddispersant specially designed for seawater reverse osmosis (SWRO)systems. Formulated by Genesys International Ltd., thispremn seawater
desalination membranes, ensuring smooth operation and long-term efficiency
of reverse osmosis plants.
Engineered to handle the unique
challenges of seawater feed, Genesys CAS controls the precipitation of calcium
carbonate, calcium sulphate, strontium sulphate, barium sulphate, and other
sparingly soluble salts. It also helps in dispersing colloidal and
inorganic particles, reducing fouling and maintaining optimal flow rates across
the membrane.
With proven performance in
both large municipal desalination plants and industrial seawater
systems, Genesys CAS has become a trusted choice for maintaining consistent
water quality and extending membrane lifespan under harsh saline conditions.
Product Overview
Seawater reverse osmosis
systems operate under high pressure and elevated salt concentrations, which
significantly increase the potential for scale formation on membrane surfaces.
Scaling leads to a reduction in water flux, increased differential pressure,
higher energy costs, and eventual membrane damage.
Genesys CAS was developed to specifically combat these issues
in seawater environments. Its advanced formulation inhibits the crystallisation
and deposition of scale-forming salts even under extreme salinity, high
recovery rates, and high temperature conditions. It also works as an effective
dispersant, preventing colloids, silt, and organic matter from accumulating
on the membrane surface.
The result is maximum
system uptime, consistent permeate quality, and significant reduction in
maintenance frequency — all while lowering overall operational costs.
Key Features and Advantages
- Outstanding Scale Control in Seawater Systems
Genesys CAS is engineered to effectively prevent the precipitation of calcium carbonate and sulphate scales that typically occur in seawater RO systems. It allows plants to operate at higher recovery rates without the risk of scaling or performance deterioration. - Effective Against Multiple Scale Types
The formulation provides broad-spectrum protection against barium sulphate, strontium sulphate, calcium carbonate, and calcium phosphate. It ensures stable performance even in systems with high mineral concentrations and elevated total dissolved solids (TDS). - Superior Compatibility with SWRO Membranes
Genesys CAS is fully compatible with polyamide thin-film composite membranes from all major manufacturers, including DOW, Hydranautics, Toray, and LG Chem. It does not damage or chemically alter the membrane surface. - Excellent Dispersion of Suspended Solids
In addition to scale inhibition, Genesys CAS helps disperse iron, manganese, silica, and colloidal particles, keeping them in suspension and preventing fouling on the membrane surface. - Optimised for High TDS and High Pressure Conditions
Its chemical stability and performance remain effective under high salinity levels (up to 45,000 ppm TDS) and temperatures up to 35°C, making it ideal for demanding seawater desalination environments. - Low Dose, High Efficiency
Due to its concentrated formulation, only a small dosage (typically 2–6 mg/L) is needed, making it highly economical while maintaining effective protection. - Environmentally Friendly and Non-Phosphate Formula
Genesys CAS is free from phosphates and harmful heavy metals, aligning with global environmental and discharge regulations. It ensures minimal ecological impact and safer handling. - Reduces Maintenance and Operating Costs
Regular use of Genesys CAS leads to longer membrane life, fewer cleanings, lower chemical consumption, and reduced downtime — all translating into significant cost savings.
Applications
Genesys CAS is suitable
for all types of seawater desalination and reverse osmosis systems, including:
- Municipal Desalination Plants
Provides consistent protection for large-scale drinking water production plants treating seawater feed. - Industrial SWRO Systems
Used in industries such as power generation, petrochemicals, refineries, and marine operations, where reliable desalination is essential. - Offshore and Shipboard Systems
Effective in compact and high-pressure desalination units onboard ships and offshore rigs. - Coastal and Island Installations
Ensures stable freshwater supply in coastal resorts, islands, and remote communities dependent on seawater sources. - Hybrid Systems (RO + Thermal)
Compatible with hybrid systems where RO is used alongside thermal desalination for improved efficiency.

Mode of Action
- Inhibition of Crystal Growth
Genesys CAS interferes with the nucleation and growth of sparingly soluble salts, preventing their transformation into large, insoluble crystalline scales on the membrane surface. - Threshold Effect
Even at low concentrations, the product maintains high efficacy by preventing salts from reaching their saturation point, allowing the RO system to operate beyond conventional limits. - Dispersion of Particulates
The dispersant component of Genesys CAS attaches to suspended solids and colloids, keeping them dispersed in the feed stream so they can be removed in the concentrate without adhering to the membrane. - Membrane Protection
By minimising scaling and fouling, Genesys CAS helps maintain a consistent permeate flow rate, stable salt rejection, and reduced differential pressure — ensuring prolonged membrane efficiency.
Dosage and Application Guidelines
The recommended dosage
depends on the feed water chemistry, recovery rate, temperature, and
concentration factor. The typical dosage range is 2–6 mg/L, but this can
vary based on site-specific scaling potential.
For best results:
- Feed Water Analysis
– Conduct a complete analysis of feed water to determine scaling potential
using software such as Genesys Membrane Master®.
- Injection Point
– Inject Genesys CAS continuously into the feed stream before the
cartridge filter or high-pressure pump.
- Dilution
– It can be used neat or diluted with RO permeate or deionised water.
Avoid dilution with chlorinated water.
- Monitoring
– Regularly monitor system parameters such as differential pressure,
recovery rate, and permeate conductivity to ensure optimum dosing performance.
Storage and Handling
- Store in a cool, dry, and well-ventilated area,
away from direct sunlight.
- Avoid freezing or storing above 40°C.
- Use chemical-resistant dosing equipment (PVC,
PVDF, or PE materials are recommended).
- Always wear protective gloves, goggles, and clothing
during handling.
- Shelf life: Minimum 12 months in unopened
original containers.
Health and Safety
Genesys CAS is classified
as low-hazard under normal handling conditions. It is non-flammable,
non-volatile, and does not produce harmful vapours. However, standard safety
practices should be followed:
- Avoid contact with eyes and skin.
- In case of contact, rinse thoroughly with clean water.
- Do not ingest or inhale the chemical.
- Always consult the Material Safety Data Sheet (MSDS)
before use for detailed handling and first-aid information.
Performance and Operational Benefits
Using Genesys CAS in seawater
desalination systems delivers measurable operational advantages:
- Maintains stable differential pressure across
the RO membrane.
- Ensures maximum water recovery without the risk
of scaling.
- Minimises the need for chemical cleaning and membrane
