FST Series Single Pass Reverse Osmosis System

Water Treatment System

For applications where ultra-high purity isn’t required (e.g., <10 ppm TDS), a single pass RO offers the best balance of performance, simplicity, and operational cost. It’s faster to install, easier to maintain, and more economical than double-pass or deionization systems—without compromising on water safety or regulatory compliance.

Single Pass Reverse Osmosis System Introduction:

A single pass reverse osmosis system is a robust and cost-effective water treatment solution. This reverse osmosis system is designed to remove up to 95-99% of dissolved salts, ions, organic compounds, bacteria, and other contaminants from raw water. Single pass reverse osmosis systems are ideal for bottled water plants, food and beverage factories and light industrial processes, providing consistent, high-purity permeate water in a single filtration step.

In a single pass configuration, pre-treated feed water is pressurized and forced through semi-permeable RO membranes. Contaminants are retained and flushed away as concentrate (reject), while purified water—known as permeate—is collected for immediate use or further polishing.

Features of Single Pass Reverse Osmosis Machine:

High Rejection Rate: Effectively removes TDS, heavy metals, nitrates, fluoride, microbes and more.
Modular Design: Scalable from 500 GPD to 20,000+ GPD capacities to suit your production needs.
Integrated Pre-Treatment: Includes multi-media filter, activated carbon filter, and cartridge filter to protect membranes and extend lifespan.
Stainless Steel or FRP Housing Options: Corrosion-resistant construction for durability.
Automatic Operation: PLC or microprocessor control with auto-flush, low-pressure protection, and high-pressure cutoff.
Energy Efficient: Optimized pump and membrane selection reduce power consumption.
Compact Footprint: Easy to install and integrate into existing production lines.

Water Treatment Machine FAQ:

Q: What does a water treatment system do?

A: It purifies raw water (from wells, rivers, or municipal supplies) by removing impurities like sediment, chlorine, heavy metals, bacteria, viruses, and dissolved salts—producing clean, safe water suitable for drinking, bottling, food production, or industrial processes.

Q: What are the main components of a typical purified water system?

A: Most systems include:

Pre-filters (sand, carbon, cartridge);
Water softener (optional, for hard water);
Reverse Osmosis (RO) unit – core purification stage;
UV sterilizer or ozone generator – for microbial control;
Polishing filters (e.g., 0.22μm);
Storage tank & re-circulation loop (for large-scale use);
Systems can be customized based on source water quality and end-use requirements.

Q: Can it treat well water or river water?

A: Yes—but heavily contaminated sources may require enhanced pre-treatment, such as:

Iron/manganese filters;
Ultrafiltration (UF);
Chemical dosing (anti-scalant, chlorine);

A full water analysis is essential before system design.

Q: Does it remove bacteria and viruses?

A: Absolutely. While RO membranes block most microbes, we add a final disinfection step:

UV lamp: Destroys 99.99% of bacteria/viruses without chemicals;
Ozone injection: Provides residual protection in storage tanks.

Note: RO alone is not a sterilization method—final disinfection is critical for potable water.

Q: Is the system automated?

A: Yes. Modern systems feature:

PLC or microprocessor control;
Auto-flushing, low-pressure shutdown, and leak detection;
Real-time monitoring of TDS, flow rate, pressure;
Optional IoT connectivity for remote diagnostics.
