ZW1500 junior

Summary

Product identification

The SUEZ ZeeWeed 1500 Junior is a pressurized ultrafiltration model designed for small flows. It features PVDF hollow fiber membrane chemistry and an outside-in flow path.

Typical applications:

• Testing membrane compatibility with water & wastewater streams.
• Running multiple lab or field experiments in parallel.
• Testing compatibility and suitability of chemical or cleaning processes on existing membrane applications.

General properties:

• Nominal pore diameter: 0.02 µm – for optimal removal of particulates, bacteria, and viruses.
• Membrane material: PVDF hollow fiber – provides high mechanical strength and chemical resistance.
• Filtration flow path: Outside-in – provides uniform flow distribution and high solids tolerance.
• Shell: Transparent – allows visibility of the membrane during operation.

• Backwash flow: 35 L/h (0.2 gpm)

Storage and handling

Modules must be stored between 5°C and 35°C (41°F to 95°F). Do not expose the membrane module to sources of heat, ignition, or direct sunlight (UV light).

Start-up procedure

A detailed start-up procedure is provided in the full document for preparing a new ZeeWeed 1500 Junior module prior to use. This procedure includes steps for installation, activation solution preparation (2000 mg/L sodium hypochlorite at 35°C to 40°C), module filling, recirculation and soaking (5 hours), and draining and rinsing.
