過濾器待處理的水由入水口進入機體，水中的雜質沉積在不銹鋼濾網上，由此產生壓差。通過壓差開關監測進出水口壓差變化，當壓差達到設定值時，電控器給水力控制閥，驅動電機信號。設備安裝后，由技術人員進行調試，設定過濾時間和清洗轉換時間，待處理的水由入水口進入機體，過濾器開始正常工作，當達到預設清洗時間時，電控器給水力控制閥、驅動電機信號，引發下列動作：電動機帶動刷子旋轉，對濾芯進行清洗，同時控制閥打開進行排污，整個清洗過程只需持續數十秒鐘，當清洗結束時，關閉控制閥，電機停止轉動，系統恢復至其初始狀態，開始進入下一個過濾工序。過濾器的殼體內部主要由粗濾網、細濾網、吸污管，不銹鋼刷或不銹鋼吸嘴、密封圈、防腐涂層、轉動軸等組成。懸浮液中的固體顆粒大、粒度均勻時，過濾的濾渣層孔隙較為暢通，濾液通過濾渣層的速度較大。應用凝聚劑將微細的顆粒集合成較大的團塊，有利于提高過濾速度。
