Director, Rochem

ROCHEM offers an extensive range of treatment products.

We design and deliver custom membrane-based systems engineered for each client’s unique wastewater conditions and treatment volume.

Our solutions integrate reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) technologies, providing scalable treatment capacity from pilot studies to full-scale installations.

Treatment Solutions

  • Rows of green and white industrial tanks with metallic components in a storage facility, with shelves and windows in the background.

    Pre-Treatment

    Ultrafiltration (UF), Nanofiltration (NF)

    When wastewater volume requires additional conditioning before reverse osmosis, we integrate UF or NF into the treatment process. These pretreatment technologies remove challenging contaminants and protect downstream RO membranes.

  • DTRO

    Disc Tube Reverse Osmosis

    Rochem designed & patented this unique reverse-osmosis module which has revolutionized the use of membranes for saltwater desalination and the subsequent treatment of landfill leachate & other difficult waste waters.

  • On a rooftop, a white rectangular container with a door and a smaller box on the side, and yellow Rocksley-branded cylinders inside, with a partly cloudy sky in the background.

    Containerized Systems

    Modular Design, Rapid Deployment

    Fully integrated treatment systems housed within standard-sized shipping containers. These containerized solutions provide a compact, self-contained treatment plant that simplifies transportation, installation, and commissioning.

  • Rows of yellow high-pressure cylinders labeled 'ReadiD'. Part of an industrial water treatment or filtration system with metal piping and valves.

    TS Module

    High Capacity

    The TS spacer tube module series are designed to allow us to house more membrane material in the same volume as a DT module, for difficult water which contains less suspended solids.

  • Industrial equipment with yellow columns and a control panel, situated inside a warehouse with a metal roof.

    Pilot Systems

    Proof of Concept, Risk Reduction

    Evaluate wastewater characteristics and validate treatment performance before full-scale installation. Pilot systems allow customers to confirm treatment effectiveness, optimize system design, and reduce project risk through real-world testing.

    Lifecycle Service

    Long-Term Reliability

    Rochem supports customers throughout the entire system lifecycle, from commissioning and performance optimization to maintenance and system upgrades. Our service team works closely with operators to ensure long-term reliability and consistent treatment performance.

  • Multiple blue plastic containers with yellow caps, labeled as membrane cleaner, arranged in rows.

    Membrane Cleaners

    Membrane Care, Performance Protection

    While most of our systems operate without the need for chemical pretreatment, our cleaning solutions are available to support optimal performance when specific water conditions require it.
