Offshore oil field Walnut shell filter water treatment equipment
Summary
Walnut Shell Media
Efficiently remove oil from North Sea produced water
Solids do not impact the efficiency
Suitable for off-shore use
Walnut Shell System
Reduced footprint through efficient backwash design and finer shell media
Reduced weight
Reduced backwash water volume
How Do Walnut Shell Filters Work
§ Continuous pressurized media bed
§ Bed(s) cycle based on time or Δ P
§ Media is recharged using backwash cycles
§ Oil is adsorbed not absorbed
§ Used to removed SS and free oil
§ Walnut shell media have an equal affinity for oil and water
§ Very low attrition rate
