A brackish water treatment plant for paper making is a system that treats high-TDS (salty) groundwater/river water and produces water suitable for pulping, bleaching, machine showers, boiler feed makeup, and cooling in a paper mill.
Paper mills are sensitive to salts and hardness because they cause scaling, corrosion, deposits, and quality defects (spots/holes, poor brightness).
Why Paper Mills Require Brackish Water Treatment
Using untreated or poorly treated brackish water in paper production leads to several operational challenges:
- Chemical Interference: Dissolved salts can react with sizing agents and dyes, leading to inconsistent coloring and poor ink absorption in the final paper.
- Scaling and Deposits: Minerals like calcium and magnesium can form hard scale inside pipes and on the surfaces of "drying cylinders," reducing heat transfer efficiency.
- Corrosion: High chloride levels found in brackish water are highly corrosive to stainless steel components and the fine wire meshes used in paper-forming sections.
- Product Quality: Excessive minerals can cause "pinholes" or spots in high-grade paper, affecting the smoothness and brightness of the sheets.
Why RO is usually the core for brackish water in paper mills
RO reduces:
- TDS / chlorides (corrosion control)
- Hardness (scale control)
- Sulfates (deposit control)
This improves:
- Sheet quality and brightness stability
- Wire/felt cleanliness
- Fewer nozzle blockages in showers
- Lower chemical usage in the wet end
Key design points (important in paper mills)
- Pretreatment is critical: paper mills often have variable turbidity/color.
- Silica control: if silica is high, design RO recovery carefully (or use partial softening/antiscalant strategy).
- Scaling risk: hardness + alkalinity + sulfate drives scaling-may need softener or lime softening upstream for high recovery.
- Material selection: high chlorides → choose proper SS/FRP/PVC for piping & tanks.
- Brine disposal: RO reject needs a plan.
If you share these 5 values, we can design the suitable Brackish Water Treatment Plant For Paper Making:
1.Raw water source (borewell/river/estuary)
2.Raw water TDS (mg/L) and hardness (mg/L as CaCO₃)
3.Turbidity/color/iron levels (if known)
4.Required treated water flow (m³/hr)
5.End use split: % for process, boiler, cooling
