Wastewater operator continuing education

Clarifier Capacity: Four Ways to Overload It

Training certificate — California requires no renewal hours

Secondary clarifiers can get overloaded in four different ways, each affecting sludge handling and effluent quality differently. This hour shows how to spot these overloads using plant data and make the right operator moves to keep the clarifier working smoothly.

Course summary, as it appears on your certificate

Enable operators to understand the four operational changes that can overload a secondary clarifier, their effects on process performance, effluent quality, sludge handling, and energy use, and to apply diagnostic methods and operator decisions that optimize clarifier capacity and avoid costly mistakes.

Level 2 — what each change does to the plant — effluent, efficiency, sludge and energy — assumes Level 1

Credit awarded: 1 hour — Technical

AquaCert does not mark its own homework: a licensed operator reviews the content and the course cannot be sold while that review is out of date.

One hour of study is one hour of credit. Your certificate reports the hours, which is what California records against your renewal.
