COMPLETE The following specification particularly describe the invention and the manner in which it is to be performed. Title of invention: "The treatment of effluent from resin manufacturing plant" Field of invention: Present invention relates to the industrial liquid waste treatment. More particularly it relates to the treatment of liquid waste coming out from Resin Manufacturing Plant. Prior art: Resins are manufactured for various purposes including purification of water. During the manufacturing process of ■resin large amount of water is used. Naturally these units let out large quantity of liquid waste. The water coming out of such units is of typical character. Being loaded with high amount of COD, BOD & TDS, it cannot be disposed of as it is without treatment. Also because of the typical character of this water it cannot be used for any purpose because of high amount of dissolved impurities. It is this character of this effluent which poses lot of difficulties for the industry in storage and disposal. The toxic dissolved solids & other organics, contribute to the high level of COD.BOD & TDS making it extremely difficult for the effluent to be disposed of as it is, being beyond local/national pollution control board norms. This typical characteristic of this effluent was the main reason for putting these units among high polluting industries in India. Drawbacks of Prior art: The traditional methods of treatment procedures such as Equalisation, coagulating agents, clarification, filtration, bio reactor aeration and filtration for land disposal and treated sludge for drying beds, the end water is not within the Pollution Control Board norms. Recently, reverse osmosis method is being used by some industries. This system is an filtration and not a treatment. Generally one gets 50% super ant and 50% reject with double the concentration. Reject water poses lot of difficulties for storage as well as disposal. Sun drying for reject water requires huge land for storage. Also it has a serious problem of percolation which results in contamination of fresh water source. As regards the incinerationjt's main problem is disposal of ash. Also energy requirement is very high in this case. Object of present invention Object of present invention is to provide a full proof zero discharge system for resin manufacturing plant liquid waste. Furthermore object of present invention is to provide a system which is economical can be used as per requirement.

This invention is illustrated in the accompanying drawings, throughout which like reference letters indicate corresponding parts in the various figures. According to present invention, "The treatment of effluent from resin manufacturing plant" process starts with the equalisation of various streams in equalisation tank.( 1 ) The equalised liquid/mixture so prepared is now ready for continuous chemical treatment. Chemical flow is maintained in chemical dosing tank (2 ).For easy & quick mixing of chemicals these are kept in slurry form. The formulations added at this stage include mixtures of oxidising agents and flocculating agents. The oxidising agents include mixtures of permanganate salts and peroxide compounds. Flocculating agents include mixtures of sulphates of 3rd analytical group of cations. Waste water treated with said formulations is retained in the reaction vessel ( 3 ) for a period of one hour to six hours for a complete reaction. After treatment sludge & liquid is separated. Sludge is discharged from the bottom of reaction vessel ( 3 ) & taken to the drying yard.

This mixture is then directed to the reaction vessel for complete reaction for one hour to six hours. After treatment precipitated sludge is discharged through the bottom of the reaction vessel & super ant liquid is taken into the buffer tank.
