Foreword
Central
Board for the Prevention and Control of water Pollution came into
being in 1974 and since then the Board is involved in various projects,
with a view to aim at controlling the environmental pollution which
are of conventional and industrial in orientation, under the Water
Act, 1974. One of the ongoing projects is the Man-Made Fibres -the
implementation of Minimal National Standards (MINAS) which includes
synthetic and semi-synthetic (Rayon)fibres. The Pollu- tional load
in manufacturing synthetic fibre is mainly organic in nature whereas
in rayon industry the most important poll~tant is zinc which is
toxic to aquatic life. The toxicity of zinc in India, a tropical
zone, will be more acute than in the countries with a much lower
average ambient water temperature and thus concentration of zinc
has to be brought down to the stringent limit which is practically
achievable. To achieve such level as stipulated in MINAS by the
industry, an action oriented programme of Central Board has been
initiated and forms the main objective of this reported project.

The present investigation is a case study on J.K. Rayon, Kanpur describing
the mechanism of zinc, which is used in the regeneration process 6f
cellulose, escapes through various routes. Based on the study, specific
measures to recover zinc from wastewater to conform quality of effluent
to MINAS, are recommended. Besides this Ganga water quality of a short
stretch in the vicinity of J.K. Rayon is also discussed. Dr. lnamul
