Based on the solubility of some salts, these tend to deposit on membranes when water passes through the membrane surface. These salts precipitate on the surface causing fouling and hence affect output.
SPECTRAGAURD / TITAN
Our range of high performance antiscalants have been specifically developed to meet the following criteria
- Excellent scale inhibition
- Effective across a wide pH range.
- Compatibility with membranes
- Compatible with other products.
- Cost effective.
- Safe to handle and safe to use.
Key features of our antiscalants SPECTRAGAURD / TITAN range are
- Dendrimer technology.
- Elimination of acid feeding
- Phosphate free and environmentally friendly
- Operational on higher LSI than most other common anti-scalants
- Effective at higher silica/iron levels
- Approved by NSF and conformation to ANSI 60 standards
- Approved from membrane manufacturers such as Dow Filmtec, Koch, Hydranautics
A corrective and preventive membrane program of an RO plant must use high performance membrane cleaners. Usually membrane cleaning is implemented when operating parameters, flux, conductivity or ∆P ( pressure differential) change siginificantly. It is advisable to clean at an early stage of fouling because foulants may be difficult to clean later or the damage may be permanent to the membrane.
VASU-PWT’s Lavasol range of cleaners include
- Low pH cleaner
- High pH cleaner
- Special silica cleaner
- Organic cleaner
- UF membrane cleaners
We also provide comprehensive cleaning programs for regular maintenance.
Non-oxidizing biocides are used either in a cleaning program or during normal operation of an RO plant. Dosage typically depends on extent of micro fouling as well as the frequency of membrane cleaning and equipment downtime.
Our Bioguard range of biocides are specifically formulated and compatible with all types of membranes.
Membranes in any membrane separation system are the heart of the plant and the process. The performance of an RO / UF membrane can be impaired by impurities that foul the membrane suface during operation. These foulants/impurities can foul the membrane and cause loss in production of clean water and hence reduce overall plant efficiency.
