Aeratsioonikava

Aeratsioonikava is an Estonian term that translates to aeration plan. It refers to a structured approach for introducing oxygen into a system, most commonly in the context of wastewater treatment or pond management. The primary goal of an aeration plan is to ensure sufficient dissolved oxygen levels are maintained to support biological processes or prevent undesirable conditions.

In wastewater treatment, an aeration plan outlines the methods and timing for oxygen delivery to activated sludge tanks. This oxygen is crucial for aerobic bacteria to break down organic pollutants in the wastewater. The plan typically specifies the type of aeration equipment used, such as diffusers or mechanical aerators, their placement, and the required airflow or agitation rates. It also considers factors like the influent wastewater characteristics and the desired effluent quality.

For pond management, an aeration plan aims to improve water quality in lakes, reservoirs, or aquaculture ponds. Insufficient oxygen can lead to fish kills and the release of harmful substances from the sediment. An aeration plan in this context would detail the equipment (e.g., surface aerators, diffusers), the areas of the pond to be aerated, and the duration and intensity of aeration to prevent stratification and anoxic zones. The effectiveness of an aeration plan is often monitored through regular measurements of dissolved oxygen levels.
