Nutshell Filter
The DS21 nutshell filter effectively eliminates free oil and suspended solids from oil field-produced water, refinery wastewater, and various water sources including steel mill direct spray and caster water, ethylene plant quench water, copper concentrate decants and cooling water. This method is highly efficient in treating suspended solids, oily residues, ash and metallic hydroxides from industrial liquids produced by petrochemicals and other industries. Nutshell media, being resistant to heavy oil surges, experience significantly less fouling compared to other media. Additionally, this media is easy to clean and rarely requires replenishment, typically only 5-10% annually.
