💧 Waterco 2000 SPDD Commercial Bobbin Wound Filter Tank – 4 Bar, Air Scour Nozzle Plate System

Over 3 m² filter area with 94 m³/hr flow rate – industrial-grade filtration for Olympic and major municipal facilities

🏊 Product Overview

The Waterco 2000 SPDD Commercial Bobbin Wound Filter Tank delivers over 3 square metres of filter area and an impressive 94 m³/hr flow rate, positioning it as one of the most capable filters in the SPDD air scour range. With a commanding 2000mm tank diameter and 6-inch (160mm) industrial connections, this filter handles pools up to 752,000 litres – suitable for Olympic competition pools, major water parks, and the largest municipal aquatic centres.

The innovative Air Scour Nozzle Plate System introduces pressurised air directly into the massive 5,360 kg media bed, reducing backwash water consumption by up to 25% while achieving superior media cleaning through vigorous air/water agitation. At this industrial scale, water savings translate to substantial operational cost reductions – potentially over 100,000 litres annually on backwash water alone.

Built using Waterco’s precision digitally-controlled filament winding technology, this commercial filter tank features seamless bobbin-wound fibreglass construction engineered for decades of demanding industrial service. The 1200mm deep media bed provides exceptional particle capture across the full 3.14 m² filter area, while manhole access ensures easy inspection and maintenance of the air scour system. Supplied as tank only with 4 bar pressure rating.

📏 Pool Sizing Guide

Sizing Principle:

The filter’s flow rate should achieve complete pool water turnover within the required timeframe. Commercial pools typically require 6-hour turnover rates for optimal water quality, with 8-hour turnover acceptable for lower-demand applications.

Formula:

Required Flow Rate (m³/h) = Pool Volume (m³) ÷ Turnover Time (hours)

Pool Capacity Compatibility:

Application	Turnover Time	Maximum Pool Volume
🏊 Olympic Competition Pool	6 hours	564,000 litres
🏢 Major Municipal Complex	6 hours	564,000 litres
🌊 Large Water Park	6 hours	564,000 litres
🏨 Major Resort Complex	6 hours	564,000 litres
🏋️ Elite Leisure Centre	6-8 hours	564,000-752,000 litres

This Filter:

📍 Flow Rate: 94 m³/hr at design velocity
📍 Optimal Pool Size: Up to 564,000 litres (6-hour turnover)
📍 Maximum Pool Size: Up to 752,000 litres (8-hour turnover)

💡 Capacity Note: The SPDD 2000 handles pools significantly larger than standard Olympic pools (2,500,000 litres for a 50m Olympic pool would typically use multiple filters or the SPDD 2350). For the largest single-filter installations, consider the SPDD 2350 with 130 m³/hr flow rate.

• Recommended flow rate: 80 – 94 m³/hr
• Maximum flow rate: Do not exceed 94 m³/hr
• Connection: 160mm / 6″ to match filter flanges

Air Scour Requirements:

• Industrial-capacity air blower for pressurised air injection
• Heavy-duty pipework to nozzle plate connection
• High-capacity blower required due to 3.14 m² bed area

💡 Note: This is a tank-only product. Multiport valves, face pipework kits, air blowers, and pumps are sold separately. Contact Parts4Tubs for 6-inch compatible valve and pipework options.

🔄 Maintenance Guide

Air Scour Backwash Procedure

The SPDD’s nozzle plate system enables a highly efficient two-stage backwash:

Stage 1 – Air Scour:

1. Set multiport valve to backwash position
2. Activate air blower (pump off)
3. Allow air to agitate media bed for 6-8 minutes (large bed requires extended cycle)
4. Air breaks up compacted media and dislodges trapped debris

Stage 2 – Water Backwash:

1. Switch off air blower
2. Activate pump for water backwash
3. Continue until sight glass runs clear
4. Total backwash time significantly reduced vs conventional filters

Routine Maintenance Schedule

Task	Frequency	Procedure
Check pressure gauge	Weekly	Record baseline and monitor for increases
Visual inspection	Weekly	Check for leaks, unusual sounds, pressure anomalies
Air scour backwash	When pressure rises 0.5-0.7 bar above baseline	Follow two-stage procedure above
Rinse after backwash	After each backwash	30-60 seconds to settle media
Inspect manhole seal	Quarterly	Check for wear, replace if necessary
Check nozzle plate	Annually	Inspect via manhole for damage or blockages
Full media replacement	Every 5-7 years (sand) or 10+ years (glass)	Replace completely

Pressure Gauge Guide

📊 Clean Filter Baseline: Establish after fresh media installation
📊 Backwash Trigger: 0.5-0.7 bar above baseline
📊 Maximum Operating Pressure: 4 bar

Water Savings Calculation

With up to 25% reduction in backwash water:

💎 Filter Media Information

Compatible Media Types

Media Type	Filtration Rating	Capacity Required	Lifespan	Key Benefits
Silica Sand	20-40 microns	5,360 kg	5-7 years	Economical, proven performance
Glass Media	5-15 microns	4,405 kg	10+ years	Finer filtration, longer life
ZeoSand/Zeolite	3-5 microns	As specified	5 years	Superior clarity, ammonia removal
AFM (Activated Filter Media)	1-5 microns	As specified	10+ years	Bio-resistant, self-sterilising

Standard Media Configuration:

• Sand Capacity: 5,360 kg (over 5.3 tonnes of 16/30 grade silica sand)
• Glass Media Capacity: 4,405 kg
• Support Gravel: 804 kg (deduct from sand capacity if used)

💡 Industrial Recommendation: With 5,360 kg media capacity, glass media offers exceptional long-term value for major facilities – finer filtration (5-15 microns vs 20-40 for sand) with 10+ year lifespan dramatically reduces total cost of ownership at this scale.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The SPDD 2000 is suitable for pools up to 564,000 litres with a 6-hour turnover, or up to 752,000 litres with an 8-hour turnover.

Q: How does this compare to the SPDD 1800?

A: The SPDD 2000 offers 24% more flow rate (94 m³/hr vs 76 m³/hr), 24% more filter area (3.14 m² vs 2.54 m²), and 24% more media capacity (5,360 kg vs 4,330 kg). Both use 6-inch connections, making the SPDD 2000 an upgrade path without replumbing.

Q: Is this suitable for Olympic pools?

A: A standard Olympic pool (50m × 25m × 2m = 2,500,000 litres) would typically require multiple filters or the larger SPDD 2350. The SPDD 2000 is ideal for Olympic training pools, 25m competition pools, and pools up to approximately 750,000 litres.

Q: How much media does this filter require?

A: The filter requires 5,360 kg of sand (over 5.3 tonnes) or 4,405 kg of glass media – substantial capacity for excellent dirt-holding in the most demanding industrial applications.

Q: Do I need additional equipment for the air scour system?

A: Yes, you’ll need an industrial-capacity air blower and appropriate pipework to connect to the nozzle plate system. The 3.14 m² filter area requires a high-capacity blower for effective air distribution.

Q: What’s the total weight when filled?

A: Empty weight is 807 kg. With 5,360 kg of sand media, total filled weight is approximately 6,200 kg (over 6 tonnes). Ensure your plant room floor can support this substantial industrial load.
