The following discussion will be mainly concerned with diatomite filtration of salt water and industrial waste streams and subsequent subsurface injection. Filtration usually follows other treatment methods that may be used. Diatomite filtration is one of the most versatile, reliable and economical methods available to remove undissolved solids from liquids. Expenditures of several million dollars have gone into the careful design of filtration equipment and proper selection of filter aids. New ideas and techniques are continuously being developed to aid adequately in insuring safe and trouble free underground injection.
