PAH Removal

Adsorption process for removing pyrene, phenanthrene, and fluoranthene

The adsorption process using Expanded Clay Aggregate (ECA®) as an absorbent has the following characteristics:

1. Easy to operate among other treatment techniques.

2. High application efficiency.

3. Cost-effectiveness and Ease of treatment process.

Expanded Clay Aggregate (ECA®) can manually be dispersed into the treatment tank using a measuring scoop and this, in turn, provides easy-to-use one-step chemistry.

Expanded Clay Aggregate (ECA®) has high adsorption capacity for removing carcinogenic and mutagenic hydrocarbons (Pyrene, Phenatherene, and Fluoranthene) and heavy metals such as nickel, lead, chromium from oil and gas effluents.

With the use of Expanded Clay Aggregate (ECA®), using the sorption method, these pollutants can be removed. The maximum sorption level can be reached when 4g of  Expanded Clay Aggregate (ECA®) is added to the water. The removal efficiency would be 94.15% for pyrene, 92.61% for phenanthrene, and 93.91% for fluoranthene.

Our treatment process with Expanded Clay Aggregate (ECA®) removes heavy metals, oil and grease, and suspended solids from industrial effluents. ECA® absorbs trace metals, soluble metals, and soluble solids from effluents and allows the resulting flocculants to settle faster. Further, facilitate releasing water for drier sludge cakes.
