Hopper Clarifier Operation And Solution Clarification Training

Learning Outcomes

• Demonstrate the ability to start up, operate, and shut down a hopper clarifier according to standard operating procedures.
• Apply monitoring techniques to assess clarification efficiency and identify deviations in solution quality.
• Analyze common operational problems such as turbidity, sludge buildup, and flow variations to implement corrective actions.
• Evaluate safety hazards associated with hopper clarifier operation and apply relevant safety protocols.
• Perform routine maintenance checks and cleaning procedures to ensure equipment longevity and performance.
• Implement record-keeping practices for operational data and maintenance logs as per regulatory requirements.

Target Audience

This course is designed for process operators, plant technicians, and maintenance personnel involved in solution clarification operations within mining, chemical, and water treatment industries.

Prerequisites

None — open enrollment.

Course Outline

Practicals

Overview

Practical sessions provide hands-on experience with hopper clarifier operation, including start-up, shutdown, parameter adjustments, and troubleshooting. Learners will operate a pilot-scale clarifier, prepare and dose flocculant, and interpret process data to reinforce theoretical concepts.

Practical Activities

• Pre-Start Inspection and Start-Up — Learners conduct a pre-start safety inspection of the clarifier and ancillary equipment, then perform the start-up sequence including filling the tank and initiating feed. (2h)
• Flocculant Preparation and Dosing — Learners prepare a flocculant solution at the correct concentration and dose it into the feedwell while observing floc formation. (2h)
• Normal Operation and Parameter Adjustment — Learners monitor key parameters (overflow clarity, underflow density, rake torque) and make adjustments to optimize performance. (3h)
• Troubleshooting and Shutdown — Learners diagnose and resolve common operational issues such as rag accumulation or high rake torque, then perform an orderly shutdown. (3h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
