Reverse Osmosis Systems

Custom-Engineered for Optimal Water Purity and Performance

At ALSI, we custom engineer Reverse Osmosis Systems to meet the specific needs of your process, delivering the water quality your operations demand. Our designs maximize system performance while minimizing operating costs, and are trusted in a wide range of industrial, commercial, and municipal applications.

Why Choose ALSI Reverse Osmosis Systems?

Customized for Superior Water Treatment

Every ALSI RO system starts with a thorough analysis of your raw water source. Our experienced design and manufacturing teams carefully evaluate the contaminants present to determine the optimal system configuration. Energy usage, installation, and operating costs are all carefully balanced—without ever compromising water quality.

Our commitment: Uncompromised water quality, user-friendly operation, and complete customer satisfaction.

Whether you need a single-pass or double-pass RO system, multi-media filtration, carbon filtration, UV disinfection, or other advanced treatment options, we work closely with you to design a complete, tailored water treatment solution.

How Reverse Osmosis Works

Reverse osmosis is a powerful water filtration process that forces water under high pressure through a semipermeable membrane. Only water molecules pass through, leaving behind dissolved salts, minerals, and contaminants. This results in highly purified water collected for use, while waste (brine) containing impurities is discarded or treated separately.

The RO process includes:

  1. Pre-Treatment: Sediment and carbon filters protect the membrane by removing larger particles, chlorine, and organic matter.
  2. High-Pressure Filtration: Water molecules are pushed through a 0.0001-micron membrane, rejecting salts and impurities.
  3. Wastewater Disposal: Concentrated contaminants are flushed away.
  4. Storage and Delivery: Purified water is stored and dispensed on demand.

What Does RO Effectively Remove?

Our RO systems effectively remove a wide range of impurities, including but not limited to:

  • Fluoride
  • Arsenic
  • Salt
  • Chlorine
  • PFAS
  • Heavy metals
  • VOCs
  • Microplastics
  • Herbicides, pesticides, and more
