Water treatment and online monitoring
The train follows the analysis and the balance: mechanical filtration, clarification or UF, dosing, softening, RO, EDI or disinfection, then the monitoring points and service. The checklist runs in that order.
Eight steps from analysis to service
- 01Water analysis
Salinity, hardness, iron, turbidity, SDI, silica and organics. No equipment is selected without a water analysis.
- 02Water balance and flow
m³/h and the daily consumption profile; the winter minimum temperature sets the membrane area; recovery and where the concentrate goes: discharge, evaporation or return.
- 03Permeate requirement
A standard or the production regulation: boiler and district-heating make-up, pharmaceuticals and beverages, electronics and electroplating, chemicals, food production; each has its own limit.
- 04Mechanical stage
Media filters and softeners are the first line of defence for the whole train: they remove suspended solids, iron, chlorine and hardness; bag and cartridge filters sit ahead of the membranes.
- 05Membrane stage
UF retains suspended solids, colloids, bacteria and viruses; RO retains dissolved salts. Check SDI, salinity, hardness, silica, organics, recovery and concentrate. RO is not installed where softening is enough.
- 06Chemical stage and polishing
Dosing, EDI or ion exchange, disinfection by UV, ozone or reagents. Tanks, pumps, piping and instrumentation, PLC automation with a water-quality log.
- 07Monitoring points
By duty: flow, pH, temperature, conductivity, turbidity, TSS, COD/TOC, oxygen, hydrocarbons. Provide bypass, sample conditioning, automatic cleaning, laboratory validation and a maintenance log.
- 08Service
Membrane cleaning, cartridge replacement, chemicals. Membrane life is not promised without pre-treatment data.
From basic probes to contamination analysers
- Why it is measured
- Instantaneous and totalised volume for discharge and balance control
- What to watch
- Measurement station and flow regime
Data for operators and external systems
- Representative sampling and conditioning
- Local HMI, archive, trends and alarm limits
- Industrial protocols and API/gateway preparation
- Integration with state or corporate platforms after their technical interface is confirmed
What we do not do
- We do not select equipment without a water analysis
- We do not install RO where softening is enough
- We do not promise membrane life without pre-treatment data
What is needed for the train and the measurement station
Water analysis, measurement ranges, installation point, sampling conditions, communications and reporting requirements. On that basis we offer raw-water analysis and train calculation, membrane selection by actual composition rather than "by flow rate", installation, commissioning and staff training.
