Auto Backwash Filtration System 10-700 M3/h Swimming Pool Water Treatment Swimming Pool Water Treatment
Hydraulic Automatic Aeration Fine Filter | Pool & Water Park Circulation Filtration System
Water Park Water Treatment Filter, Auto Backwash, 10–700 m³/h)
Hydraulic Automatic Aeration Fine Filter (Pool Circulation & Water Treatment System)
This equipment is a water-filtration and aeration unit designed for swimming pools, water parks, spa/thermal pools, seawater pools and related circulation systems—including water-treatment support for wave pools / tsunami-pool circuits—but it is not a wave-generating machine itself.
It works by simulating natural water-flow/aeration behavior, increasing dissolved oxygen, trapping suspended solids via multi-layer composite media, and using water-power/flow characteristics to trigger automatic backwashing—reducing manual maintenance versus traditional pressure-filter setups.
Typical flow handling: ~10–700 m³/h (model-dependent). Suitable for mid-to-large pools and water-attraction circulation loops.
⚠️ Note: Wave-pool / tsunami-pool “design process” specs (e.g. blower-wave 0.8–1.2m, vacuum-tsunami 1.5–3m, area 1000–20000㎡, ~2㎡/person capacity) describe the target pool/system context; the filter here treats the circulating water, not creates waves.
- Aeration / Oxygenation : Improves dissolved oxygen, helps oxidize/remove odors and some dissolved impurities
- Multi-layer Composite Filter Media : Intercepts fine particles; targets improved clarity and reduced turbidity
- Float/Separation Effect : Foam/light organics brought to surface and managed during flow/backwash
- Automatic Backwash by Water Power : Uses hydraulic characteristics to auto-backwash; less manual intervention
- Compact/Modular Layout: Smaller footprint vs. spread-out traditional filter rooms
- No Separate Backwash Pump (in integrated design): Integrated backwash tank/flow path, lowers electric use
- Low-speed High-flow Circulation Compatible: Electric demand can be ~1/4–1/5 of traditional pressure-system approaches (application-dependent)
- Corrosion-resistant, Non-toxic Water-contact Materials: For long service life in chlorinated/marine-like circuits
- PLC/Control Compatible: Can be coordinated with pool-system controls (per project BOM)

(If you also list “vacuum wave/tsunami” or “blower wave pool” as separate products later, keep those on separate pages: Wave Ball / Blower Wave Machine / Vacuum Tsunami System.)

- Swimming pools (indoor/outdoor)
- Water parks / water-play areas (circulation treatment)
- Wave pool water-circulation support (not wave generation)
- Tsunami/“sea-wave” pool system water treatment support (area/height specs belong to wave system design)
- Thermal/spring/SPA pool circulation
- Seawater/brine pool circulation (material/compatibility check required)
- Aquatic show / themed attraction water loops
- Resort/hotel pool complexes
- Training/competition pool auxiliary filtration
- Can be paired with: disinfection, pH/ORP control, lane lines, life-saving equipment
Also-remind other scenarios
If buyer actually needs wave experience, direct them to Wave Ball / Blower Wave / Vacuum Tsunami; if they need pool sanitation chemicals, direct to water-treatment chemicals; if they need safety, direct to life jackets/rings; if they need pool marking, direct to lane lines.

What buyers should budget beyond “filter unit price”:
- Filtration system: filter unit(s) + multi-media + replacement media
- Circulation pump & piping (inlet/outlet 75/100/110 etc.)
- Disinfection/chemical system (chlorine/ORP/pH/algicide/clarifier) — still required
- PLC/electrical cabinet & sensors (may coordinate with pool system)
- Civil works: machine room, sump, access, drainage, anti-corrosion
- Installation & commissioning (per agreement)
- Freight, customs, duty — freight NOT included, EXW/FOB Guangzhou
- If also building wave/tsunami feature: budget wave/tsunami CAPEX + pool-area civil separately (waves ≠ filter)
Cost-saving angle to highlight:
This hydraulic-auto-backwash design can reduce labor and lower electricity profile vs traditional pressure-filter rooms; but total OPEX depends on bather load, turnover, water loss, chemical regime and maintenance discipline.
Selection tips for buyers:
- Provide pool area, volume, turnover rate, bather load (~2㎡/person ref.)
- Define flow (m³/h) and pipe sizes
- Confirm chlorinated vs seawater/thermal water (material compatibility)
- Do not size by “wave height” alone—size by water circulation & filtration turnover
- MOQ/lead-time: plan procurement early; factory inspection recommended

Q1: Is this a wave machine / tsunami machine?
A: No. It is a filtration/aeration/auto-backwash water treatment unit. It can serve circulation loops of wave/tsunami pools, but does not generate waves.
Q2: What flow rate does it handle?
A: Typically 10–700 m³/h by model/configuration; final sizing by pool volume, turnover rate and bather load.
Q3: Does it remove the need for chlorine/chemicals?
A: No. It handles physical filtration/aeration; disinfection/pH/ORP control is still required per standards.
Q4: What’s the difference between wave pool and tsunami pool?
A: Wave pool usually uses blower/air (≈0.8–1.2m); tsunami/vacuum pool uses vacuum-chamber surge (≈1.5–3m), larger area/civil cost. The filter supports water treatment for both.
Q5: Is freight included?
A: No, freight not included; buyer arranges shipping (EXW/FOB Guangzhou).
Q6: MOQ & lead time?
A: One MOQ (wholesale/OEM common), ~14 days after deposit (model-dependent), 40%/60% payment typical.
