PROBLEM STATEMENT :
Due to the use of acid in latex coagulation, the effluent discharged from latex rubber factories is acidic and re-dissolves the rubber protein. Normally, chemical coagulant is added into rubber industrial wastewater in order to separate the solid:liquid fraction. This has caused the wastewater treatment practice in rubber industry more challenging in terms of cost and effluent quality issue. As far as rubber industry is concerned, the environmental issues are caused due to the chemical usage at the different stages of operation. The end products formed after the use of chemicals will be poisonous and highly toxic and whose effective disposal will become very much essential.

PRODUCT DESCRIPTION:
This study has successfully recovered Durable Latex Granules from rubber industrial wastewater via aerobic granular sludge technology without using any coagulant or additional supporting carrier material.. The Durable Latex Granules possessed dense, compact, spherical, regular, and strong features. These characteristics have initially granted the developed rubber–base wastewater highly efficient in sludge settleability in the wastewater treatment. Besides, the dried portion of the granules has potential for fabrication of new latex-based eco-products such as rubber pavement for outdoor playground.
COMMERCIAL POTENTIAL :
Rubber industrial wastewater
Eco-product
Latex granules cultivated from the SBR can be fabricated into new eco-products such as latex floor mat and interlocking rubber pavement

Dense
Compact
ORIGINALITY / NOVELTY:
Originality :
Aerobic granulation technology that can cater for both industrial wastewater treatment and recovery of by-product in the form of latex granules .
Novelty :
Latex-based product recovery system and applications of rubber industrial wastewater treatment
Coagulant-less recovery method in latex industry
A small foot-print treatment system
