Water chemistry for paper mill runnability.
Product selection depends on raw water quality, furnish type, white-water closure level, microbiological load, process chemistry, machine design, metallurgy and discharge expectations.
Analysis First
Water analysis before product recommendation.
TDS, SDS and certificates are shared upon request.
Liberta supports paper mill water systems with PureGuard® boiler, cooling and RO programs, BlancoWT® wastewater and DAF treatment, and field-validated runnability chemistry.
Typical water-related problems
| Problem | Why It Matters | Response |
|---|---|---|
| Scale and inorganic deposits | Boilers, cooling systems, RO, showers, seal water and process water circuits. | Reduce heat transfer, restrict flow, plug nozzles and increase cleaning frequency. |
| Corrosion | Boiler, condensate, cooling, closed loop, vacuum/seal water and utility systems. | Can damage piping, exchangers, pumps, tanks and process equipment. |
| Slime and microbiological fouling | White-water circuits, showers, cooling towers and process-water loops. | Can cause odour, deposits, runnability problems and heat-transfer loss. |
| Pitch, stickies and resin deposits | Recycled furnish, stock preparation, paper machine circuits, felt/wire sections. | Can create deposits, sheet defects, surface build-up and cleaning burden. |
| Foam | White-water, DAF, biological treatment, process tanks and sludge handling. | Can reduce tank capacity, destabilize separation and cause overflow/operation problems. |
| Turbidity / suspended solids | Process water, DAF, wastewater pre-treatment and recycle loops. | Increase fouling, solids load and downstream treatment pressure. |
| Color and variable effluent load | Recycled paper, coating, dye/print-related streams and wastewater. | Can increase discharge burden and require validated decoloring routes. |
| Sludge dewatering difficulty | Wastewater sludge, DAF sludge, biological sludge and fibre-rich sludge. | Impacts cake dryness, chemical consumption and disposal burden. |
System mapping
| System | Risk | Solution |
|---|---|---|
| Boiler / steam / condensate | Oxygen corrosion, scale, sludge, pH imbalance, condensate corrosion. | PureGuard® oxygen scavengers, alkalinity/pH control, internal treatment and condensate line programs. |
| Cooling towers | Scale, corrosion, deposits, microbiological risk and blowdown pressure. | PureGuard® cooling tower programs including scale/corrosion, dispersants, biocides and P-Free options where applicable. |
| Closed loops / chillers | Low-flow corrosion, pH drift, glycol-water compatibility and deposit accumulation. | PureGuard® closed loop corrosion/scale inhibitors, glycol-loop review and cleaning/flushing routes. |
| RO / demineralization | Membrane scaling, fouling, poor product/dosage selection and cleaning need. | PureGuard® 7-series antiscalants, PureGuard® 3-series cleaners and RO-Watel product/dosage support. |
| Process / white water | Slime, pitch/stickies, filler deposits, turbidity, foam and runnability instability. | PureGuard® process-water conditioning + BlancoWT® support where clarification or solids control is needed. |
| Felt / wire cleaning | Fibre, filler, resin and microbiological deposit build-up. | PureGuard® cleaning and maintenance support selected according to deposit type and application method. |
| Wastewater / DAF / sludge | TSS, color, foam, COD fractions, oily residues and sludge dewatering. | BlancoWT® coagulants, flocculants, AntiFoam, Color Removal and Jar Test Services. |
