Usage Methods

• Equipment Selection: Select the appropriate model and configuration according to the raw water quality, impurity type, filtration capacity requirements, and on-site installation conditions, ensuring it matches the actual water treatment needs.

• Installation & Commissioning: Install the sand cylinder on a flat, firm foundation, correctly connect the raw water inlet, filtered water outlet, and drainage pipeline. Professional technicians will commission the equipment, check the 6-position multi-functional valve, adjust the filtration pressure and flow rate, and test each valve function to ensure normal operation.

• Daily Operation: According to the actual water treatment needs, switch the multi-functional valve to the corresponding position: use the normal filtration mode for daily water purification; switch to normal backwash when contaminants accumulate; use post-backwash residual discharge to remove remaining impurities after backwashing; select bypass drainage or bypass circulation when filtration is not needed; switch to system off to shut down the equipment.

• Maintenance: Regularly inspect the 6-position multi-functional valve to ensure flexible switching and no leakage. Check the filter media periodically, clean or replace it when filtration efficiency decreases. Inspect the stainless steel tank and pipelines for abnormalities (such as leakage, loose connections), and repair or replace worn parts in a timely manner.

Safety Precautions

• Ensure the sand cylinder is installed correctly and the pipeline connections are tight to avoid water leakage, pressure loss, or equipment damage during operation.

• Do not exceed the specified operating pressure during use; regularly check the pressure gauge to prevent tank deformation or damage caused by overpressure.

• When switching the multi-functional valve, ensure the equipment is in a stable state to avoid water hammer or pressure impact, which may damage the valve or pipeline.

• When performing maintenance, cleaning, or filter media replacement, shut down the system and cut off the water supply first to prevent water splashing and personal injury.

• Avoid collision, extrusion, or heavy impact on the stainless steel tank to prevent deformation or fracture.

• Store and use the equipment in a well-ventilated, dry environment, away from direct sunlight, high temperature, and corrosive substances, to protect the stainless steel material and extend the service life.

• Operators should be familiar with the functions of the 6-position multi-functional valve and the equipment operation manual before use; avoid misoperation that may cause equipment failure or safety hazards.

• Keep the equipment out of the reach of children and unauthorized personnel to prevent misoperation and accidental injury.

FAQ

• What materials are used in the construction of the top-extraction sand tank?

The tank of the Top-Discharge Sand Cylinder (Stainless Steel) is manufactured from premium-grade, eco-friendly stainless steel composite material. This material ensures exceptional durability, strong resistance to deformation and fracture, as well as excellent wear resistance, making the equipment suitable for long-term use in various water treatment environments.

• How does the water distribution system in the sand tank function?

The sand tank is equipped with a uniquely designed water distributor, which ensures a uniform and stable water flow throughout the entire filtration system. This even water flow avoids filtration dead angles, improves filtration efficiency, and ensures consistent water quality output. Meanwhile, the efficient drainage system cooperates with the water distributor, enhancing the overall filtration and backwash performance of the equipment.

• What are the specific functions of the 6-position multi-functional valve?

The 6-position multi-functional valve manages the entire workflow of the sand cylinder, with five key functions: 1. Normal Backwash: Expels accumulated contaminants from the filter; 2. Post-Backwash Residual Discharge: Removes remaining impurities from the water discharge line; 3. Bypass Drainage: Drains water without filtration; 4. Bypass Circulation: Circulates water without filtration; 5. System Off: Shuts down the operation. It supports flexible switching to meet different operation and maintenance needs.

• Can we customize the equipment?

Yes, we offer OEM/ODM customization services based on your specific needs.

• How often should the sand cylinder be backwashed?

The backwash frequency depends on the influent turbidity and impurity content. Typically, it is recommended to perform normal backwash every 8-24 hours. If the raw water has high turbidity and more contaminants, the backwash frequency should be appropriately increased to ensure filtration efficiency and avoid filter media clogging.
