fine screens are typically used to remove material that may create operation and maintenance problems in downstream processes, particularly in systems that lack primary treatment. typical opening sizes for fine screens are 1.5 to 6 mm (0.06 to 0.25 in). very fine screens with openings of 0.2 to 1.5 mm (0.01 to 0.06 in) placed after coarse or fine screens,rules and regulations - oklahoma department of,the text of all oklahoma statutes can be found on the oklahoma state courts network website. before being adopted, deq rules undergo an extensive public review process as set by statute and the office of administrative rules within the oklahoma secretary of state’s office.
