Liquiline System CAT860

Summary

Product identification

Product: Liquiline System CAT860 Type: Automatic sample conditioning system for supplying process measuring devices with filtered sample from the inlet or sludge activation phase of a wastewater treatment plant.

Application

The Liquiline System CAT860 enables fully automatic collection and filtration of aqueous samples. It is designed for:

• Collection of aqueous samples from industrial processes
• Communal and industrial wastewater treatment plants

Key Features and Benefits

• Robust and reliable:
  • Peristaltic pump for interference-free sampling.
  • Membrane filtration for particle and algae-free samples.
  • Automatic filter backflushing with cleaner and air.
  • Optional hose trace heating system.
• Simple and user-friendly:
  • Control via a CA80 analyzer.
  • Compatible with Flexdip CYH112 installation.
• Easy maintenance:
  • Tool-free replacement of pump hoses and filter.

Function and System Design

The system uses a peristaltic pump to draw samples through a filter element. An automatic cleaning function backflushes the filter and sample hoses with a cleaning solution or compressed air.

A complete system comprises:

• Liquiline System CAT860 sample preparation system
• Local operation with soft keys and status LEDs
• Filter unit
• Automatic cleaning function with compressed air (external supply required)
• Peristaltic pump
• Vacuum pump for chemical cleaning
• Optional housing heating
• Sample hoses (filter to pump, pump to analyzer), optionally heated
• Cleaner (ordered separately)

Performance Characteristics

• Sampling method: Control unit, Liquiline System CA80 analyzer
• Filtrate quantity (with Memosens technology): 5.5 to 16.5 ml/min (factory setting: 8.25 ml/min). Values determined with new filters.
• Suction height of peristaltic pump: Max. 5 m (16 ft)
• Hose length, filter to pump: Max. 5 m (16 ft)
• Hose length, pump to analyzer: Max. 30 m (98 ft)

Installation

• Suction height:
  • Between filter and sample preparation (A): Max. 5 m (16.41 ft)
  • Between filter and analyzer (A+B): Max. 10 m (31.81 ft) total, with A always max. 5 m.
• Mounting conditions: Avoid locations with aggressive gases, siphoning effects, or upward gradients to the sampling point. Ensure sufficient load-bearing capacity, a level surface, protection from heating and magnetic fields, and free air circulation (at least 150 mm from side panels). Do not mount directly above inlet channels.
