Water & Desalination

RO scale control & membrane cleaning

Keep the membrane duty in focus. Scale prevention and deposit removal require different decisions.

Illustrative application context

01 / THE CHALLENGE

Understand the duty before the treatment.

Changing feedwater chemistry, concentration and deposits can affect membrane operation. A useful evaluation starts with the water analysis, operating history and the nature of the deposit—not a product dose.

Conditions that shape the decision

Feedwater analysis, source variability and recovery
Membrane type, operating limits and pretreatment
Pressure differential, normalized flow and cleaning history

02 / THE APPROACH

Define the mechanism. Scope the evaluation.

Assess scale tendency and operating conditions before considering preventive chemistry. Treat cleaning as a separate, deposit-led task, with membrane supplier limits and a defined cleaning endpoint.

Illustrative process sequence. Evaluation boundaries and measured endpoints are agreed for each application.

Scale control

BRONEL AS 310 is a candidate RO antiscalant in development. An evaluation would consider the feedwater, concentration conditions and proposed dosing point.

Acid membrane cleaning

BRONEL MC 330 is an acid membrane cleaner in development. Deposit characterization and membrane compatibility must guide any proposed cleaning evaluation.

03 / VALUE TO EVALUATE

Agree what progress should mean.

These are evaluation objectives. They are not claims of achieved product performance.

01
Normalized permeate flow and differential pressure
02
Cleaning endpoint and recurrence of deposits
03
Chemical demand, water use and total treatment cost
