Introduction
I.Product Applications
RENATUR 331 is a biomass-based hyper-branched polymer, free of nitrogen and phosphorus, and biochemically degradable. Suitable for the RO system of seawater desalination, it has a good scale-inhibiting effect on a large number of salts, minerals and microorganisms in seawater. It can extend the service life of reverse osmosis membranes, and improve the efficiency of seawater desalination with good environmental benefits.
II.Scope of Applications
1. Particularly recommended for seawater desalination, brackish water, brine, and other reverse osmosis systems.
2. Effectively controls the scaling of calcium carbonate, magnesium carbonate, calcium sulfate, barium sulfate and other inorganic salts.
3. The applicable PH value range is 6-11, and the applicable temperature is 0-45 ℃.
4. Has extremely high calcium carbonate chelate dispersibility, and the calcium carbonate chelate dispersant value can reach 400-410mg calcium carbonate per gram of dry basis scale inhibitor.
5. Very effective against non-polymeric iron and aluminum pollution, with a limit value of iron and aluminum on the concentrated water side of up to 0.5ppm.
6. Has a good scale-inhibiting and dispersing effect on silicon scale, with no scaling risk when the SiO₂content on the concentrated water side is within 100ppm.
7. Can prevent microbial pollution to a certain extent.
III.Physical and Chemical Indicators
Appearance: Light amber transparent liquid
Density (density @25 ℃): 1.15-1.25 g/cm3
PH Value: Original fluid, 1.0-3.0
Active Ingredient Content: ≥ 42.0%
IV.Product Usage
RENATUR 331 is a concentrated liquid, and the dosage is usually 0.2-0.5ppm. Before using the product, the water quality before the membrane needs to be analyzed, and the RENATUR dosing calculation software should be used for simulation to determine the precise dosage. Do not blindly add or use excessive amounts to ensure the best effect and economy.
V.Packaging and Storage
RENATUR 331 is factory-packed in IBC ton barrels or according to customer requirements, and is transported as non-hazardous general goods. Please store it sealed in a ventilated, light-shielded, and room temperature environment. The shelf life is 24 months.
