## Several Types of Clarifying Filtration

In previous post, I shared several types of filtration methods and more about cake filters. In this post, I want to share to you several types of clarifying filtration.

The main objective of clarifying filters is to remove small amounts of solids or liquid droplets from either liquids or gases. The liquid may be drinking water, wine, beer, oil, etc., and it is usually the liquid which is the valuable product.

In clarifying filters, the particles are trapped inside the filter medium or on its surfaces. Surface forces catch the particles and immobilize them on the surfaces or within the flow channels.

In general, clarifying filtration are categorized into liquid clarification and gas cleaning. Read More

## A Simple calculation on How to Determine Time Required to Obtain Certain Volume of Filtrate

In this post, I want to share how to do a simple calculation on determination of time required to obtain certain amount of filtrate in a filtration test. We will still use basic equation as in previous post.

For example, we have this case.

A filter press with a surface of 50 m2

C (weight of solid per volume of liquid) = 135 kg solid/m3 liquid

μ = 0.001 N sec/m2

α (specific resistance of the cake) = 1.1 (1011) m/kg

Rf (resistance of filter cloth) = 6.5 (1010) m-1 Read More
