This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry.

Environmental properties of organic matter contained halogen and sulfur were studied in sediments of bleached kraft pulp mill effluent (BKME) recipient lakes and 2 m 3 outdoor enclosures (mesocosms). The BKME contributed to 1% (v/v) of the total water flow in the lake downstream of the pulp mill where the sediments contained to 4 mg of tetrahydrofuran extractable organic halogen Kraft-type pulp mills, where chlorine gas is used in the first stage of the bleaching process, are the biggest culprits.

Chlorine gas reacts with compounds in wood lignin to create dioxin precursors and many other chlorinated compounds. These toxic compounds, called organochlorines, are released into the air and water when wastes are dumped. In   New bleached kraft pulp mills and modernised existing mills have been required to meet strict environmental guidelines set by regulatory authorities.

This has led pulp mill designs to include state-of-the-art technology applications and for existing mills to incorporate new technological advances in process design which improve liquid effluent COVID campus closures: see options for getting or retaining Remote Access to subscribed content   Extractable, organically bound chlorine (EOCl), which is determined by neutron activation analysis (NAA), has been used as a measure of pollution by chlorinated organics.

In this study, the concentrations and distribution of extractable organohalogens (EOX = EOCl + EOBr + EOI) were measured in sediment, blue crab, fishes, birds, and terrapin collected at an estuarine marsh and a The kraft process is the most widely used commercial process, by far.

In the United States, there are 87 bleached kraft mills and 17 bleached sulfite mills.
