System 06 | Process Reliability Systems
Intelligent Filter Press Control System
Most washeries run multiple filter presses on manual coordination, with an operator walking the floor to check status, judging when a batch is done, and sequencing discharge by hand. System 06 replaces that with centralized monitoring, sensor-driven end-of-feed, and automatic multi-press discharge queuing.

DEFINITION & OVERVIEW
What is the Intelligent Filter Press Control System?
System 06 integrates every filter press in the building into one central control point, giving an operator visibility and control that previously meant walking between presses to check loosen, close and feed status by hand.
Three functions run together: remote status monitoring across the whole press bank, an automatic end-of-feed that ends the batch based on measured filtrate flow and duration rather than operator judgement, and first-in-first-out discharge queuing that sequences multiple presses automatically and shuts down downstream conveying once every press clears discharge.
All three depend on the same feed-line instrumentation: a pressure transmitter, a tank level transmitter, and a filtrate flow detection device, which is what turns 'the press is probably done' into a measured decision.
Remote Press Monitoring
Loosen, close and feed the status of every press visible centrally, with remote manual/automatic changeover.
Automatic End-of-Feed
Filtrate flow and feed duration are evaluated against calculated set points; the system ends the feed automatically.
Automatic Discharge Queuing
First-in-first-out queuing across multiple presses; downstream conveying stops automatically when all presses are off discharge.

KEY FEATURES
Key Features & Performance Highlights
System 06 replaces manual, per-press judgement with centralized, sensor-driven control across the entire filter press bank.
Centralized CPU Integration
The filter press CPU integrates with the central control system, enabling remote detection and operation of every press in the building from a single interface.
Sensor-Driven End-of-Feed
Filtrate flow and feed duration are evaluated continuously against calculated set points, and the system ends the feed automatically at the right point, not on a fixed timer or visual estimate.
Queued, Automatic Discharge
Multiple presses discharge in first-in-first-out order automatically, and downstream conveying shuts off by itself once every press has cleared discharge; no manual coordination between presses is required.
WORKING PRINCIPLE
How the Filter Press Control System Works
Three instruments feed the control logic that drives the three automated functions.
Feed Line Sensing
A feed line pressure transmitter and feed tank level transmitter provide the control system with real-time feed conditions for every press.
Filtrate Flow Measurement
An auto-calibrating, partially filled-pipe flow detection device measures filtrate flow continuously across a 0–120 m³/h range.
Automatic End-of-Feed Decision
Filtrate flow and feed duration are evaluated against calculated set points; the system ends the feed automatically once the batch is complete.
Discharge Sequencing
Presses ready to discharge are queued first-in-first-out, with the central system coordinating which press discharges next.
Downstream Conveying Shutdown
Once all presses are off discharge, downstream conveying stops automatically rather than running unnecessarily.

COMPARISON
Centralized vs. Manual Filter Press Operation
With System 06 (Centralized)
Manual Filter Press Operation (Most Plants)
Applications of the Filter Press Control System
System 06 is most valuable on any washery running more than one filter press, where manual coordination between presses becomes the bottleneck.
Multi-Press Filter Banks
Coordinates discharge sequencing across several presses without manual scheduling.
Removing Operator Judgement from Cycle End
Ends feed based on measured filtrate flow and duration, not a fixed timer or visual estimate.
Reducing Downstream Conveyor Runtime
Automatic shutdown when all presses clear discharge cuts unnecessary conveyor operation.
Retrofitting Existing Filter Press Banks
Integrates onto existing presses via feed-line and filtrate instrumentation without replacing the presses themselves.
Central Control Room Visibility
Gives operators remote status and manual/automatic changeover without floor-level intervention.
High-Duty-Cycle Dewatering Circuits
Reduces the operator overhead of running multiple presses continuously through a shift.

Filter Press Control System | Frequently Asked Questions
Common questions from engineers in coal washery processes evaluating centralized filter press automation.
It automates three functions: remote monitoring of every press’s loosen/close/feed status, automatic end-of-feed based on measured filtrate flow and duration, and automatic first-in-first-out discharge queuing across multiple presses.
A filtrate flow detection device and feed duration are evaluated continuously against calculated set points; the system ends the feed automatically once those conditions are met, rather than relying on a fixed timer or operator judgement.
Yes, the system integrates via feed line pressure, feed tank level, and filtrate flow instrumentation and connects the filter press CPU into your central control system.
The flow detection device holds ±0.5% accuracy across a 0–120 m³/h range, is auto-calibrating, is polyurethane lined, and is rated IP65 for wet duty.
Operators no longer need to walk the floor checking press status, judge when a feed cycle is complete, or manually coordinate discharge order across multiple presses; all three are handled centrally and automatically.
