NHPA150C

Summary

Product Identification

The NHPA150 Series consists of Submerged Flat-sheet Membrane Bioreactors (MBR) designed for biological wastewater treatment. These modules incorporate thin membrane sheets for improved flexibility, allowing for more membrane area per footprint compared to earlier series. The module configuration can be adjusted to suit various water capacity, height, and width requirements while maintaining operational efficiency.

Applications:

• Sewage wastewater
• Industrial wastewater
• Food processing wastewater
• Sludge thickening process

Flat Sheet Element (Model: TSP-50080)

• Nominal Pore Size: 0.08 µm
• Materials:
  • Membrane: PVDF and PET non-woven fiber
  • Nozzle: PE
• Effective Membrane Area: 0.7 m² (7.5 ft²)
• Dimensions (w x l x thk): 480 x 800 x 1.8 mm (18.9 x 31.5 x 0.07 in.)
• Weight (reference):
  • Dry: 0.25 kg (0.6 lbs.)
  • Wet: 0.5 kg (1.1 lbs.)

Module Characteristics

Materials:

• Frame: 304 stainless steel (316 SS optional)
• Manifold: Polypropylene
• Air Diffuser: Polypropylene

Connections:

• Manifold: ANSI 1 1/2 inch flange using M12 bolts/nuts (one flange per each deck)
• Air Diffuser: ANSI 1 1/2 inch flange using M12 bolts/nuts (two flanges per Aeration block)

See the official PDF for exact tabulated values regarding the number of elements, total membrane area, dimensions, and weights for specific models (ECS035, NHPA150-1C, NHPA150-2C, NHPA150-3C, NHPA150-4C). Measurements for dimensions include filtrate header and air diffuser pipes.

Operating Limits

• Temperature: 5–40 °C (41–104 °F)

Cleaning Chemicals and Concentrations

• Sodium hypochlorite: 2,000–6,000 mg/L (10 < pH < 12)
• Oxalic acid: 0.5–1.0 wt%
• Citric acid: 1.0–3.0 wt%

Mechanical / Hydraulic

Scouring Air Flow Rate

See the official PDF for exact tabulated values for scouring air flow rates for specific models (NHPA150-1C, NHPA150-2C, NHPA150-3C, NHPA150-4C). The air supply equipment (e.g., blower) should be designed based on standard operating conditions. Air volume is measured at 0 °C and 101.325 kPa (1 atm).
