【0010】 入口から粒子収集周壁までの半径方向構成要素(以下、「収集壁」と称する)と収集壁に沿った軸方向構成要素とを含む流路をフィルタユニットに設けることによって、微粒子含有液は、回転チャンバに入って、入口から収集壁へと向かい、その後は収集壁に沿って流れた後、出口を介してチャンバから出ることができる。微粒子含有液が収集壁に沿って軸方向に通過する際に、液体中の微粒子状物質(例えば、繊維、マイクロファイバー、粒子など)は大きな遠心力を受け、従って、収集壁上に堆積されるため、出口にてフィルタユニットから出る液体には、微粒子状物質がほぼ無くなる。従って、最終的に遮断してしまうことになるバリアフィルタ(メッシュ又は有孔膜/壁など)のいずれの形態も使用せずに、濾過を達成することができる。従って、フィルタの流動性及び分離(すなわち、濾過)性能は、収集される微粒子状物質の量に関係なく、効果的に一定となり得る。メッシュバリアを必要とせずに、フィルタユニットは、濾過を行う際に遮断されることを効果的に回避することができる。
