Slow Sand Filtration for Water Treatment
Slow Sand Filtration for Water Treatment

Slow ,sand, filtration relies on both physical and biological activity in controlling plant pathogens. In a ,slow sand filter,, the filter bed is constructed of a medium with high surface area which can be colonized by suppressive micro-organisms. This fine media also presents a physical barrier to the passage of spores of plant pathogens.

A Computationally Efficient Model for Predicting Overflow ...

The alternative presented here is a model-based approach. The model is used to predict the internal behaviour of the sand bed and the overflow losses. The model can be used for the following applications: - Process monitoring; the operator is able to see if the sand bed is still growing and whether the overflow density is too high.
