Durable Latex Granules: A Potential Recycled Products Recovered from Treated Latex Wastewater
Abstract
Aerobic granulation technology have successfully developed latex-sludge granules without using any additional supporting carrier material or coagulant. Self-immobilized latex granules which are morphological durable in structure has contributed to high settleability in solid:liquid separation ratio in the latex-based wastewater treatment. The solids fraction of the treated wastewater are accumulated and benefited as a durable latex granules. This study aims to explore the characteristics of durable latex granules. The characteristics of the granules are significant for development of latex-based potential eco-products.
Aim
Study the reproducibility of granulation and the effect of the operation parameters on formation and stability of latex granules
Compare latex granular morphology and development in different types of wastewater
Characterize microbial community in granular sludge at various stage of granulation
Distinguish the structural properties of latex granular from rubber wastewater
Methodology b)
Result
Figure 1: Comparison of latex granular development and examine the effect of various operation parameters, in order to determine possible mechanisms controlling the granule development .
Potential Products for Commercialization

Figure 3: Latex granules cultivated from the SBR can be fabricated into new eco-products such as latex floor mat and interlocking rubber pavement
Conclusion
CONCLUSION : Latex granules are dense, compact, spherical, regular, and strong. These characteristics have granted the excellent latex-base wastewater treatment and potential for transformation of the cultivated latex-granules into new eco products.
