Mohamed, this photo shows a Human-Machine Interface (HMI) screen for a two-stage Reverse Osmosis (RO) water purification system. It displays the system's operational status, control parameters, and a simplified flow diagram. Here's a detailed explanation: 1. System Overview and Controls: The top label "触摸屏" means Touch Screen*, indicating it's an interactive display. "自动开始" (Automatic Start) is a button to initiate the system's automated operation. "蜂鸣器报警指示灯" (Buzzer Alarm Indicator Light) and "蜂鸣器声音启动" (Buzzer Sound Activated) are for alarm notifications. 2. Operational Parameters: RO Flushing Times: "一级RO冲洗时间" (First-stage RO flush time): Set to 30 seconds*. This is how long the first RO membrane is flushed to clean it. "二级RO冲洗时间" (Second-stage RO flush time): Set to 10 seconds*. This is for flushing the second RO membrane. RO Continuous Operation: "一级RO连续运行时间" (First-stage RO continuous running time): Set to 240 minutes*. This is the duration the first RO stage operates continuously. Ozone System Parameters: "气液混合泵/臭氧发生器" (Gas-liquid mixing pump / Ozone generator) "运行时间" (Running time): Set to 5 minutes*. This is how long the ozone system runs for disinfection. "间隔时间" (Interval time): Set to 60 minutes*. This is the pause between ozone system operations, indicating intermittent disinfection. 3. Water Flow Diagram and Components: Raw Water Input: Water starts from the "原水箱" (Raw water tank), then is moved by the "原水泵" (Raw water pump*). Pre-treatment: The water goes through "预处理" (Pre-treatment) (like the sand and carbon filters we discussed earlier) and then "阻垢剂加药" (Antiscalant dosing*) to prevent scaling on the RO membranes. First-Stage RO: A "低压开关" (Low-pressure switch*) protects the pump. Water is pushed by the "一级高压泵" (First-stage high-pressure pump) into the "一级RO" (First-stage RO*) unit. "一级产水" (First-stage product water*) is indicated (red light, possibly meaning not yet up to standard or just indicating flow). "一级排废电磁阀" (First-stage waste discharge solenoid valve*) releases the concentrated reject water. Second-Stage RO: The permeate from the first stage goes to a "二级水箱" (Second-stage water tank*). It's then pumped by the "二级高压泵" (Second-stage high-pressure pump) into the "二级RO" (Second-stage RO*) unit. "二级产水" (Second-stage product water*) is indicated (green light, likely meaning good quality product water). "二级排废电磁阀" (Second-stage waste discharge solenoid valve*) releases the reject water from the second stage. Post-treatment/Output: The purified water then goes through an "臭氧发生器" (Ozone generator) and "气液混合泵" (Gas-liquid mixing pump) for disinfection. There's a "气液混合泵启动" (Gas-liquid mixing pump start*) button. Finally, a "供水泵" (Supply pump*) (with a "供水泵启动" button) delivers the treated water. This screen allows operators to monitor and control the entire RO water purification process, from raw water intake to final treated water output and disinfection. 3 done, 2 left today.
