The Tech Inc. Closed-Circuit RO (CCRO) Pilot Test Skid proves how far a feed water can be recovered before scaling or fouling sets in. It runs the closed-circuit, semi-batch cycle: feed enters the loop at the rate permeate leaves, a circulation pump keeps crossflow through short vessels, pressure rises with concentration, and at the set recovery a flush valve displaces the brine with fresh feed while production continues.

Main components

Feed tank, cartridge prefilter and antiscalant dosing point
High-pressure feed pump on VFD
Circulation pump on VFD for loop crossflow
One to three pressure vessels for 4- or 8-inch elements, one to four elements each
Automatic flush (brine purge) valve and conductivity-based cycle control
Pressure, flow, conductivity, pH and temperature transmitters
PLC and HMI with cycle logic, data logging and remote access

Applications: Brackish and well water, RO reject recovery, cooling-tower blowdown, mine and industrial wastewater reuse, and ZLD pre-concentration studies.

Closed-Circuit RO (CCRO) Pilot Test Skid

Brackish water – up to 41 bar.

High-pressure – 69 or 82 bar for seawater and reject concentration.

Containerised – for long site trials.
Permeate: 0.2 to 2 m³/h (4-inch) or up to 8 m³/h (8-inch)

Recovery: set per cycle, up to 95% on suitable brackish feeds

Pressure: up to 41 bar; 69 or 82 bar options

Materials: SS316L or super duplex wetted parts

Control: PLC and HMI, CSV export
Real recovery data – cycle-by-cycle logs of pressure, flux and conductivity.

Less scaling risk – short residence time and regular brine purge.

Flexible – recovery, flux and crossflow set from the HMI.

Scale-up ready – standard elements, so results transfer to full plant.
