Description

Product Overview:
The CSM RO Membrane Filter is a high-rejection, precision-engineered reverse osmosis separation element manufactured for domestic and light-commercial drinking water filtration systems. Built with advanced thin-film composite polyamide sheet layers, this CSM RO Membrane Filter serves as the vital purification core inside your water purifier. It effectively rejects dissolved chemical compounds, heavy metal ions, fluoride, arsenic, and microscopic biological pathogens, delivering sterile, crystal-clear, and safe drinking water for households and workplaces.

In Bangladesh, municipal utility water networks and deep groundwater aquifer reserves consistently carry severe concentrations of total dissolved solids (TDS), salinity, iron residue, industrial chemicals, and fecal coliform bacteria. Standard carbon or sediment pre-filters are incapable of removing microscopic dissolved salts and heavy metals. Integrating an authentic CSM RO Membrane Filter provides an impenetrable molecular barrier, reducing dangerous TDS levels by up to 98% and ensuring complete protection against waterborne infections.

Key Features of CSM RO Membrane Filter:
• Precision 0.0001-Micron Molecular Pore Size: Allows only pure water molecules to pass through while rejecting dissolved chemical solutes and microscopic viruses.
• High TDS Rejection Rate: Delivers a reliable 95% to 98% stabilized salt rejection efficiency across variable raw water salinity profiles.
• Advanced Thin-Film Composite Technology: Utilizes dense polyamide spiral-wound layers reinforced with premium feed spacers to resist premature surface compaction and fouling.
• Standard Residential Sizing: Designed with universal 1812 / 2012 dimensions, ensuring seamless compatibility with standard residential membrane housings.
• Wide Pressure Operating Range: Functions smoothly across domestic booster pump operating pressures without causing sheet delamination or structural rupture.
• Dry Vacuum-Sealed Packaging: Shipped in vacuum-sealed, tamper-evident protective wrapping to guarantee long shelf life and pristine hygiene prior to installation.

Why Choose CSM RO Membrane Filter for Purifiers:
Choosing an authentic CSM RO Membrane Filter guarantees consistent salt rejection and steady pure water delivery rates throughout its operational lifecycle. Counterfeit or low-grade membranes employ defective sheet seams that crack under pump pressure, allowing untreated contaminants to bypass into your pure drinking tank.

Our genuine elements feature dense spiral windings and durable rubber brine seals that direct 100% of feed flow through active membrane pores. This prevents rapid scaling and maintains water sweetness, making everyday drinking, hot beverages, and cooking safe for entire households.

Detailed Installation and Operating Sequence:
Replacing the CSM RO Membrane Filter requires standard tools and basic care. First, turn off the water supply valve and the pure water storage tank. Disconnect the inlet tubing from the membrane vessel cap, unscrew the cap using a housing spanner, and pull out the spent membrane element using a pair of pliers[cite: 22].

Inspect the vessel interior and sanitize the housing bowl with clean water[cite: 22]. Lightly lubricate the dual black O-rings and perimeter brine seal of the new membrane with food-grade silicone grease. Firmly press the new membrane into the housing until the center stem locks into the bottom outlet receiver socket. Securely screw the housing cap back into place, reattach the tubing, and run the system to flush out manufacturing air bubbles and protective solutions for approximately 15 minutes before collecting drinking water[cite: 22].

Maintenance and Replacement Guidelines:
Maintaining optimum membrane performance requires punctual servicing of the sediment and activated carbon pre-filter cartridges. Replacing pre-filters every 3 to 6 months shields the delicate polyamide layers from chlorine oxidation and particulate clogging.

Under standard domestic feed conditions, replace the membrane element every 18 to 24 months, or whenever your TDS meter indicates a significant drop in salt rejection. Green Bird Water Technology provides authentic membrane elements, digital TDS testing meters, and professional technical support across Bangladesh to ensure continuous operating reliability.

Ideal Applications:
• Domestic undersink Reverse Osmosis water purifiers.
• Wall-mounted and floor-standing cabinet drinking water filters.
• Light-commercial RO water dispensers for offices, schools, and clinics.
• Replacement maintenance for aged or fouled RO membrane elements.
