KSRO series Reverse Osmosis Systems
4,000-6,000 GPD (650-1000 LPH)

The ROTEK KSRO Series are engineered based on the KISS principle—“Keep It Simple and Smart”—Designed for commercial and industrial applications, they are built to deliver simplicity in installation, operation, and maintenance.

The innovative ROTEK "Pulse Flush" design ensures reliable performance by eliminating operational errors and consistently producing water at the desired flow rate and quality without requiring operator adjustments. With a fixed recovery rate of 60-65%, the KSRO Series utilizes a single, extra-large flow RO membrane element, capable of delivering up to 4000 GPD (650 LPH) of permeate water flow.

Advantages

  • Designed for simple and reliable operation with only
    One Power Button to operate.

  • Automatic high-frequency Pulse Flush that replaces
    the need for conventional concentrate flow regulation.

What is Pulse Flush?

​It is the key feature that allows KSRO to be operating at a 100% recovery rate during the production cycle. During the flush cycle, the flush valve opens before the saturation of concentrated water reached the level when soft water or antiscalant can’t prevent the scale formation anymore. Moreover, the sudden change of flow velocity across the membrane surface in such a short period of time causes water hammers that also help to shake off the foulants on the membrane surface in order to keep the membrane clean for a longer period of time.

Specifications

* KSRO system recovery rate is calculated based on the volume of flush water discharged
Recovery Rate = (Permeate Flow / Permeate Flow + Discharged Flush Flow)
