along with the once generated by the hydrolysis of the lignin also get liberated in to water. The treatment system envisaged should be capable enough to manage polyphenols of these two categories so that the recirculatory configuration is attained. The ret liquor generated where 20ppt seawater is used in the reactor contained 0.358 ±",0.24 mg.ml" polyphenols, 5.67 mg.ml" sugars 19.47±5.7 mg.ml" proteins and 16.11 ±6.28 mg.ml" lipids and 50 ±...25 BOD (Anon,1998). This is the upper limit which one can expect in the reactor and in the real life situation the concentrations are likely to be very low. The treatment system developed should be capable enough to bring down the highest concentration of the above components drastically so that the effluent generated is fit to be reused in the retting reactor. For the development ofsuch a system the followings were required: a. Appropriate groups of microorganisms which can uptake polyphenols , proteins sugars and lipids as sole source of carbon and energy. b. Appropriate design ofthe treatment system c. Fabrication ofthe system and standardization The following chapters deals with the above vital components ofthe ret liquor treatment system. 10
