Acid Concentration

Acid concentration involves recovering and concentrating waste acid streams such as HCl, H₂SO₄, or HNO₃ from industries like pickling, textile processing, electroplating, and chemical manufacturing. These acids, though present in dilute forms, hold significant value and can be efficiently recovered using specially designed evaporator systems. At SEDL, we offer acid concentration systems engineered for corrosion resistance, energy efficiency, and long-term operational stability.

Challenges in Acid Concentration

Recovering acids from waste streams presents unique technical difficulties due to

Highly Corrosive Nature

Strong mineral acids attack common metals, requiring special alloys or non-metallic construction.

Volatility

Some acids like HCl are volatile and need closed systems with acid-resistant condensers to minimize losses.

Fume Handling

Acid fumes are harmful and need efficient scrubbing systems to meet environmental norms.

Material Compatibility

Every component in contact with acid must withstand long-term exposure.

Low pH Environment

Demands automated monitoring and safety systems.

Our Solution

SEDL’s Acid Concentration Systems are engineered to ensure safe, efficient, and sustainable operation

Special Materials

Use of PTFE-lined carbon steel, glass-lined vessels, or high-grade alloys like Hastelloy for corrosion protection.
