After initial bench testing our clients often choose to conduct longer term tests at their facility to get a better idea on performance with a variable feed stream and it gives plant personnel a first hand feeling for how the equipment operates.
In these situations Oberlin Filter Company offers our smaller commercial automatic pressure filters on a rental basis.
For Chemical/Process Water we can supply standalone filters or supply a temporary process system that may include feed tank, pumps and necessary chemical additions.
We also have a limited number of small (0.3 sq.ft. area) manual filters available for on-site testing. They duplicate the filter operation, need 90 psi air supply, but need an operator to control sequencing.
Field Test: This test was for a turnkey colloidal suspension filtration. The test was on milk and involved adding dry chemistry to break the colloid, filtering out the solids with the result of 1 NTU of better filtrate. The process was to lower the pH to have all the colloidal milk solids drop out to produce clear water. The fat solids drop to the bottom and are filtered. What is left is dry solids and clean filtrate of 1 NTU. This test was also run on paint.
