Highlights
Rubber factory effluent's are known to cause serious-environmentalpollution problems if discharged without treatment.l Malodour produced by untreated effluent as well as the pollution of natural waterways i n rubber growing areas of natural rubber producing countries are of considerable concern
Effluent of latex concentrate factories are known to have a very much higher pollutant load than those released by crepe rubber and sheet rubber producingfa~tories.~
Conventional or anaerobic facultative ponding systems are popular for treatment of effluents from sheet rubber and crepe rubber f a ~ tories .Malodour caused by such ponding systems and the long effluent retention period of 22* d which necessitates construction oflarge ponds requiringlarge land area, are the main problems associated with ponding systems they are relatively simple to operate and maintain
Summary
Rubber factory effluent's are known to cause serious-environmentalpollution problems if discharged without treatment.l Malodour produced by untreated effluent as well as the pollution of natural waterways i n rubber growing areas of natural rubber producing countries are of considerable concern. IN TREATMENT SYSTEMS FOR SKWZ LATEX SERUM Abstract: The use of Eichhornia crassipes (water hyacinth) in conventional ponding systems for treatment of effluent from latex concentrate factories was investigated. Two types of skim serum were investigated using laboratory models of single and twin tank systems.
