Pre Treatment Plants
Brahma Fabricon

Pre-treatment in powder coating is the critical chemical process that cleans and prepares the metal surface before powder application. It removes contaminants like oil, grease, rust, and mill scale, and applies a conversion coating (usually phosphate) that improves powder adhesion and corrosion resistance.

Without quality pre-treatment, powder coating fails prematurely through chipping, peeling, or corrosion — even with the best powder and curing ovens. Brahma Fabricon’s pre-treatment plants ensure consistent, uniform surface preparation for defect-free, long-lasting powder coated products.

Key Benefits of Our Pre-Treatment Plants:

• Excellent corrosion resistance (up to 1000+ hours salt spray)
• Superior powder adhesion and finish durability
• Reduced rejection rates and rework
• Lower long-term maintenance costs
• Eco-friendly chemical options with water recycling systems

A spray pre-treatment system cleans and chemically prepares metal surfaces using multiple spray stages before painting or powder coating.

A dip pre-treatment system involves immersing components in a series of chemical tanks for cleaning and phosphating operations.

It removes contaminants, etches the surface, and activates it for strong adhesion, preventing peeling, corrosion, and defects.

Deep Type Pre Treatment Line or Transporter Type Dip for automated, continuous processing.

Yes, spray pre treatment excels for complex geometries or when faster, targeted cleaning is needed.

• STP (Sewage Treatment Plant):
  Treats domestic sewage (household wastewater like toilets, kitchens, bathrooms).
• WWTP (Wastewater Treatment Plant):
  Treats a broader range of wastewater, including industrial effluents, chemicals, and sewage.

👉 In short:
STP = domestic wastewater
WWTP = domestic + industrial wastewater

1. Screening (removal of large debris)
2. Coagulation (adding chemicals to bind particles)
3. Flocculation (forming larger particles/flocs)
4. Sedimentation (settling of particles)
5. Filtration (removing finer particles)
6. Disinfection (killing bacteria/viruses)
7. Storage & distribution

Common pretreatment methods include:

• Screening
• Grit removal
• Oil & grease removal
• Equalization
• pH adjustment
• Chemical dosing (coagulation/flocculation)

Pre-treatment refers to the initial processing of wastewater to remove contaminants that could damage equipment or interfere with the main treatment process.

Typical pretreatment steps:

1. Screening (removes solids like plastics, cloth)
2. Grit chamber (removes sand and heavy particles)
3. Oil/grease trap
4. Equalization tank (balances flow and load)
5. pH correction (neutralizing acidic/alkaline water)

• Preliminary Treatment – removes large solids and debris
• Primary Treatment – settles suspended solids
• Secondary Treatment – biological treatment (microorganisms break down organic matter)
• Tertiary Treatment – advanced purification (filtration, disinfection, nutrient removal)

Powder coating pretreatment tanks are used for degreasing, rinsing, phosphating, and passivation to improve coating adhesion and corrosion resistance.

Leading pre treatment plant manufacturers provide customized spray and dip systems for powder coating, painting, and metal finishing industries.
