Mineral residue
The salts that precipitate in the concentration limit the flow and increase membrane resistance.
Solutions / Membrany RO
Protection of RO membranes.
Productivity under control.
We combine water analysis, antiscalant selection, dosing and station work trends. This makes it known what reduces flow, when to react and whether to wash CIP is really needed.

Diagnosis before correction
Diagnosis first.
Not every change means scale. We combine water, operating parameters and station history to separate mineral sediment, impurities, biofilm and membrane damage.
Water composition and recovery
Organic and colloidal impurities
Particles and organic compounds put on the surface and shorten the cycle between washings.
Biofilm
Biological development increases the pressure difference and results in increasingly less stable station work.
Oxidation of the membrane
Contact with chlorine or other oxidant can permanently reduce salt retention.
Image of station work
Four signals speak more than a single reading.
We normalize the results in terms of temperature and power conditions. Only then can you reliably compare the work of the station in time.
Permeate stream
Shows whether the station maintains the amount of water produced after taking into account temperature.
Salt retention
It allows you to evaluate the quality of separation and capture the deterioration of active layer work.
Pressure difference
Growth indicates that the flow channels are resisting more and more.
Recovery and Consumption
It combines water balance with antiscalant dose and real load of the installation.
Protection program RO
From water composition to stable membrane operation.
The treatment product is one of the elements. An effective programme combines risk projection, pre-treatment, dosing and current trend assessment.
Get to know the rules of protection ROPower Analysis
We're testing the water composition, temperature and risk of precipitation with the planned recovery.
Risk projection
We check where the safe range of work ends and what needs to be pre-fit.
Stable dosing
We select the treatment product, dose, injection point and flow-compatible control.
Trend monitoring
We compare normalized results and react before the deviation becomes a downtime.
Cleaning decision
CIP is performed when data indicates this.
Too late to wash can fix the sediment. It's too common to charge membranes and production unnecessarily. First we determine the cause of the drop in parameters.
The correct diagnosis determines the chemistry and course of washing.Trend confirms change
The decision is based on standard flow, salt retention and pressure difference.
We recognize the type of sediment
The composition of impurities determines the order, chemistry and washing parameters.
Protect the membrane during CIP
We control pH, temperature, flow and contact time according to membrane material.
Effect on the bet
Stable station RO works predictablely.
The protection program is intended to maintain process parameters, limit unplanned interventions and give the technical team a clear basis for decision.
More stable permeate production
The work parameters are comparable over time, so deviations can be seen earlier.
Longer cycles between washings
Correct protection limits sediment and unnecessary maintenance downtimes.
Reduced energy consumption
Cleaner flow channels do not require unnecessary pressure increase.
Better investment protection
Oxidants control, dosing and CIP supports longer membrane operation.
FAQ
Questions about performance and protection of RO membranes.
Specific answers about diagnosis, anti-scalant, monitoring and the right time of CIP washing.
How can scaling be distinguished from biofouling?
We compare the difference between pressures, normal flow and salt retention with water analysis, work history and sediment from filters or CIP. The conductivity of permeate itself does not allow to reliably indicate the cause.
Can an antiscalant resolve every cause of reduced performance?
No. Antiscalant reduces the risk of precipitation of certain salts. It will not replace proper pre-filtering, biological control, oxidizer protection or proper membrane washing.
How is the antiscalant dose selected?
Based on the ion composition of water, pH, temperature, assumed recovery and concentrate conditions. Selection should also take into account the limitations of the membrane manufacturer and the actual stability of dosing.
Which parameters should be monitored daily?
Flows, pressures, pressure difference, conductivity permeate and concentrate, recovery and temperature. To assess the condition of the membranes of the value, normalize and analyse as a trend.
When should CIP cleaning be performed?
The decision is based on a change in normal flow, salt retention and pressure differential and on recommendations of the membrane manufacturer. Too late washing can fix the sediment, and too often overburdens membranes and production.

Basic parameters and a brief description of the trend will suffice. Together we will determine which data should be supplemented and what next step will be the most sensible.
