High pH Membrane
Cleaner with Biofilm-Busting Power
Geoclean 119 is a high-pH membrane cleaner specifically formulated to combat the invisible enemies of your RO and UF membranes—biofilms, microbial slimes, and embedded organic residues. When traditional alkaline cleaners plateau, Geoclean 119 goes deeper, targeting biological foulants that compromise system efficiency, water recovery, and membrane life. This powerful formulation delivers deep-cleaning performance with a dual-action punch—breaking down organic build-up while simultaneously disrupting microbial colonization. Ideal for routine CIP or emergency recovery, Geoclean 119 revives underperforming membranes with minimal downtime.
- High pH Liquid Cleaner
- Excellent removal of Colloidal Silica, Clay & Organic Contamination.
- Specialized blend of Polymers & Dispersants..
- Surfactant free formulations.
- Suitable for elevated temperature..
- Suitable for use with other Geoclean products.
Features:
- Biofilm & Microbial Control in One Step: Removes bio-organic contamination while helping prevent reformation of microbial layers.
- Deep Organic Cleaning: Clears oily fouling, food-grade contaminants, starches, and biological matter trapped within membrane pores.
- Restores Critical Performance Metrics: Helps recover normalized flow rates, improves salt rejection, and reduces differential pressure.
- Compatible Across RO, NF & UF Systems: Works seamlessly in multi-stage membrane installations without impacting polymeric integrity.
- Low Foam, High Flow CIP Compatibility: Designed for ease of circulation, rapid rinsing, and zero system interference post-cleaning.
- Ideal for Digital & IoT-Enabled Plants: Cleaning cycles can be monitored, logged, and optimized using smart control systems.
It depends upon the severity of the membrane fouling. Generally, 8 – 10% wt. /wt. solution is recommended
| A specialized blend of proprietary buffers and other components to dissolve organic foulants and disperse colloidal particles.. |
| Compatible with sea water and polyamide membranes. |
| Easy to handle. |
| Completely soluble in water. |
| In case of heavy fouling, drain the return flow (upto 20% of CIP tank volume) to the cleaning tank to prevent redisposition. |
| The solution must be discarded if it becomes turbid (increase in SDI) or discolored by removal deposits to avoid redisposition. |
| Monitor the pH of the solution during the cleaning process. If the pH remains in the desired range and the solution is not turbid, it may be used to clean subsequent stages. In the unlikely event that the pH falls, prepare a new batch and repeat steps. |
Geopure 100 is formulated to be injected neat. However, if dilution is required, use deionized water or RO permeate. If neither of these is available, softened water may be substituted. The dilution for Geopure 100 should not result in a solution strength of less than 10%. This guideline will protect the effectiveness of the internal bacteriostat, which inhibits bacterial growth in the product packaging and feed tank.
