process to make ceramic filter for iron filtration

Ceramic foam filter for better filtration of molten iron

The invention claimed is: 1. A process for filtering molten iron comprising: preparing a ceramic foam filter by the steps of: preparing a ceramic precursor comprising: 35-70 wt % refractory aluminosilicate; 10-30 wt % colloidal silica; 0-2 wt % bentonite; 0-35 wt % fuming silica; 0-10 wt % pore formers; and the balance being a solvent; impregnating an organic foam with said ceramic

An Assessment of Ceramic Filtration for a Metallurgical

Ceramic filter discs are vacuum-disc filters that comprise sintered alumina sector plates with uniform micro-pores. The micro-pores create suction through capillary action and, once wetted, the filter medium allows only liquid to pass through during the filtering process. A filter

What is a Ceramic Filter and How Does It Work? Fresh

A ceramic filtration system uses a natural ceramic media as the heart of a water filtration process. The ceramic filter cartridge, often referred to as a ceramic filter candle, processes the water and removes contaminants through a network of pores. Ceramic filtration systems exist in a variety of applications.

Quick & Easy Guide to Whole House Water Filters APEC Water

Iron water filters are a good example of a redox water purification process that removes iron and manganese through the oxidation process. These filters use manganese dioxide which acts as an oxidizer that removes electrons and precipitates iron, hydrogen sulfide and manganese out of the water making it easy to filter

Filtration: Sediment, Activated Carbon and Mixed Media

Sediment filters typically look like woven string (Figure 1), pleated paper (Figure 2) or spun polypropylene (Figure 3 and close-up Figure 4) are selected based on the particle size removed (for example, 2 microns to 100 microns). A small particle size (2- to 5-micron) filter
