Basket strainers in the coating lines catch and hold the lumps. They are also used to clean trances of pulp or paper from white water effluent before it is discharged into the environment. The presence of unwanted solid particles in glazes, for example, can mean rejection of a product. Basket strainers are installed just ahead of glaze spray equipment to prevent this. A basket strainer installed on a tank truck or rail car which must dispense liquids, can catch solid material which is not wanted.
Many chemical products undergo changes in storage or transport which result in solid residues.
The presence of solids in liquid fertilizers or pesticides, for example, can cause clogging of spray equipment. For this reason, many tank trucks and cars are equipped with strainers. 13 Chemical Processing T his industry is perhaps the largest user of basket strainers. There are innumerable areas where the presence of a basket strainer means a cleaner product, protection of equipment, or simple separation of solids from liquids. There is scarcely a chemical operation involving liquid flow which cannot be improved or guaranteed longer running life by installation of a basket strainer in the line.
