SVI stands for Sludge Volume Index, which is a measure of the settleability of sludge in aeration tanks.

• SVI is calculated by dividing the volume of settled sludge by the volume of the sludge sample.

• A lower SVI indicates better settleability of sludge, while a higher SVI indicates poor settleability.

• SVI is an important parameter in wastewater treatment plants to assess the efficiency of the aeration process.

• For example, if the SVI of aeration is consistently high, it may indic...read more

FM ratio refers to the ratio of food to microorganisms in an activated sludge system, indicating the balance between organic matter and microorganisms.

• FM ratio is calculated by dividing the food (organic matter) concentration by the microorganism concentration in the activated sludge.

• A balanced FM ratio is important for efficient wastewater treatment.

• An FM ratio that is too high can lead to excess sludge production, while a ratio that is too low can result in poor treatment p...read more
