Villa Pool Filtration System

 Villa pool filtration system is the core facility to ensure clean water and swimming comfort. Proper design not only improves filtration efficiency, but also reduces maintenance costs. Here are the key points and practical suggestions.

I. Core equipment selection

1、Circulation pump‌
            It is recommended to choose stainless steel pump, head to match the pool volume (for example, 16 meters head corresponds to 20 cubic meters / hour flow), and configure a "one with a backup" dual-pump system, backwash dual pumps run simultaneously to enhance the cleaning efficiency.

2. Filtering device‌

• • ‌Sand Tank Filter: 1 meter diameter sand tank can handle 18 cubic meters/hour flow rate, filled with quartz sand filter media (precision 5-10 microns), need to be equipped with 5 corrosion-resistant electric valves to achieve the function of automatic backwashing, positive rinsing and so on.
  • ‌alternative: Diatomaceous earth filters (3 micron accuracy) or glass media (longer life) for scenarios with higher water quality requirements.

3,Sterilization system‌
            Recommended UV germicidal lamp (99.9% sterilization rate) or ozone generator, with automatic dosing device to control the dosage of chlorine / bromine agent, to maintain the residual chlorine 0.3-1.0ppm.

II. Piping and valve design

• • ‌Piping Layout: Use UPVC-C grade pipe (wall thickness ≥ 4.5mm), main pipe flow rate control at 1.5-2m/s, avoid right-angle elbow to reduce water resistance.
  • ‌Key Valves: Install independent service valves for each pipeline, add motorized valves for return/drainage pipes to realize automatic drainage, and install check valves at the outlet end of the water pump to prevent backflow.
  • ‌protective measures against earthquakes: Pump inlet and outlet with soft connection buffer, base plus 50mm vibration-damping rubber padsThe

III. Intelligent control system

• ‌PLC control unit: Linkage pumps, sand tanks, disinfection equipment, real-time monitoring of residual chlorine, pH (need to maintain 7.2-7.8) and turbidity, and automatic alarm when abnormal.
• ‌remote management: Support cell phone APP to adjust the circulation cycle (recommended ≥4 times per day) and backwash frequency.
• 
  

IV. Installation and maintenance points

1. ‌Equipment room requirements: Load-bearing needs to be ≥ 3-5 tons / ㎡, humidity resistance of 85% or more, reserved space for maintenance.
2. ‌debugging process::
   • Start with a 24-hour pressure test (1.5 times the working pressure).
   • Sand tanks need to be backwashed for 3-5 minutes to remove impurities before rinsing the pipes for the first use.
3. ‌routine maintenance: Clean the filter cotton every half month, check the condition of the quartz sand regularly, and replace the UV lamps at 8,000 hours.

V. Low-cost DIY program (optional)

• ‌trickle filtration: Placing filter cotton and biochemical rings in layers in plastic baskets with submersible pumps (treatment capacity ≥1/4 of the pool water volume).
• ‌solar heating: Black sprinkler hose coiled into a collector, combined with a smart socket to control the water temperature.
• 

        For villa pools, the recommended choice isSwimming pool in-ground integrated machine(e.g.Oryx (brand)(brand), integrated filtration, circulation, disinfection, dosing functions, small footprint and low maintenance costs.
