Provided is a septal splint to promote healing and alignment of a user’s septum, and a method thereof. The invention further relates to a method of inhibiting the interaction of a cell bearing mammalian CCR4 with a ligand thereof, and to use of the antibodies and fragments in research, therapeutic, prophylactic and diagnostic methods. The armature further has a spring affixed to one end of the armature and affixed to the end of the solenoid, wherein the spring and armature are capable of linear motion within the fluid chamber of the valve housing and within the cylindrical plunger guide of the solenoid. In this case, some contaminants are removed by conventional gravity settling equipment, while additional contaminants are removed by membrane filtration.
