As global freshwater scarcity intensifies, seawater reverse osmosis (SWRO) desalination has become a mainstream, reliable solution for coastal cities, industrial parks, and marine engineering projects. However, high salinity, hardness, microbial activity, and complex impurity components in seawater easily cause membrane scaling, biofouling, oxidation damage, and system operation instability, which greatly reduce desalination efficiency, shorten membrane service life, and increase operational and maintenance costs. Professional and customized desalination chemical agents are the core guarantee for long-term stable, efficient, and low-carbon operation of SWRO systems. Scien Green Environment Co., Ltd focuses on R&D, production and customization of high-efficiency seawater desalination chemicals, providing full-cycle chemical solutions for global seawater desalination projects.
Core Series of Seawater Desalination Chemicals & Functional Advantages
Scien Green Environment’s seawater desalination chemical portfolio covers the entire pretreatment, membrane operation, and post-treatment process, solving common pain points of traditional agents such as single effect, poor adaptability to high-salinity seawater, large dosage, and secondary pollution. All products adopt environmentally friendly, low-toxicity, and high-purity formulas, compliant with international water treatment and environmental discharge standards, suitable for large-scale commercial desalination plants and small and medium-sized industrial desalination systems.
1. RO Membrane Antiscalant & Dispersant
Scale deposition of calcium carbonate, calcium sulfate, barium sulfate and silica is the primary cause of membrane flux decline in seawater desalination. Our independently developed antiscalants adopt optimized phosphino-polycarboxylic acid composite formula, which can effectively inhibit crystal growth and disperse micro-fouling particles under high salinity and high LSI saturation conditions. It stably controls scale formation in high-recovery SWRO systems, reduces membrane cleaning frequency by more than 30%, and extends the service life of reverse osmosis membranes significantly. Compared with traditional single phosphonate agents, our product features lower dosage, stronger high-temperature and high-pressure resistance, and no phosphorus enrichment in concentrated water, meeting strict environmental protection discharge requirements.
2. High-Efficiency Biocide & Algaecide
Seawater contains a large number of bacteria, algae and microorganisms, which easily form biological slime on the membrane surface, leading to irreversible biofouling and system blockage. Scien Green’s broad-spectrum biocides are specially formulated for marine microbial characteristics, with fast sterilization speed, long-lasting inhibition effect and strong compatibility. It effectively suppresses microbial reproduction in the water body and membrane surface, prevents biological fouling of pretreatment filters and RO membranes, and ensures continuous and stable water production of the desalination system. The product has low corrosiveness to equipment and will not cause oxidative damage to membrane materials.
3. Flocculant & Coagulant Aid for Pretreatment
Turbidity, suspended solids and colloidal impurities in raw seawater are key burdens of subsequent membrane treatment. Our composite polymer flocculants can rapidly agglomerate tiny suspended particles and colloids into large settleable flocs, realizing efficient solid-liquid separation in the pretreatment stage. It effectively reduces the solid load entering the RO system, protects precision filters and reverse osmosis membranes, and improves the overall water treatment efficiency. The product is suitable for various seawater turbidity conditions, with fast settling speed and low residual dosage, avoiding secondary pollution to water quality.
4. Dechlorinating Agent & Membrane Cleaning Agent
Residual chlorine in seawater can oxidize and damage polyamide RO membranes permanently. Our high-purity dechlorinating agents can quickly and completely remove residual free chlorine in the feed water, forming a protective barrier for membrane operation. Meanwhile, our targeted membrane cleaning agents are divided into acidic, alkaline and neutral types, aiming at scale, biological slime and organic fouling formed in long-term operation. They can efficiently restore membrane flux and water production capacity with low corrosion, helping enterprises reduce membrane replacement costs and system downtime loss.
