4000 Person Package Treatment Plant

Capacity for 2000-4000 people for mega settlement and public projects:

• Mega resort hotels — holiday villages with 400-800 rooms
• Neighborhood scale settlements — 600-1500 apartments
• City hospitals — complexes with 250-500 beds
• University mega campuses — 5000+ students
• OSB joint wastewater — small-medium organized industrial zone
• Municipality/small town — sewage treatment
• Industrial mega facilities — large factory complex

Typical usage examples:

• 800-room resort (Maldives style): Luxury tourism + reuse in irrigation + MBR option possible.
• Town/county municipality: Central wastewater treatment for a settlement with a population of 3000-4000.
• 30-factory organized industrial zone: Each factory discharges to a common central facility after pre-treatment — sectoral filter.
• 500-bed city hospital: Mega health complex — strict discharge limits.
• University mega campus: 5000-10000 students + dormitory + social facilities.

The technology we recommend for this capacity:

• Classic activated sludge + advanced N-P removal — the most economical for this scale
• MBR optional — if there is a strict water recovery target
• Sludge stabilization — anaerobic or aerobic
• Sludge dewatering — industrial decanter
• Full SCADA + redundancy — critical capacity, no downtime accepted
• Online monitoring sensors — pH, DO, MLSS, BOD proxy

Technical specifications (4000 people / 790-800 m³/day):

• Reactor material: ST37 carbon steel, 4-6 mm thickness
• Corrosion protection: Epoxy paint or bituminous coating, 15-20 years lifespan
• BOD removal: 92-96% (inlet 300-400 mg/L → outlet 15-20 mg/L)
• COD removal: 88-94% (inlet 600-800 mg/L → outlet 80-100 mg/L)
• SS removal: 95+% (outlet 20-30 mg/L)
• NH4-N removal: 85-90% (advanced biological process)
• Automation: PLC controlled, SCADA remote monitoring optional
• Energy consumption: Typical 0.4-0.7 kWh/m³ of treated water
• Footprint: Reactor only + 1 m service area
• Warranty: Mechanical 12 months, body 5 years
• Certificates: CE, ISO 9001, ISO 14001

Investment analysis for a system serving 4000 people: - Annual treated water: ~292,000 m³ - Reusable water (for irrigation): ~248,200 m³ (85%) - Operational savings (water bill): Between 25-40% of the total annual water expenses - Avoidance of municipal sewer fees: Additional savings of +30-50% depending on the region - Prevention of environmental compliance penalties: Severe penalties for exceeding discharge limits - Estimated payback period: Typically between 2-4 years - Equipment lifespan: 15-20 years (over 70% of the investment lifespan is profit) - Sustainability: Direct contribution to the conservation of water resources
