**7. Conclusions**

Water industry needs to address the spent membrane management, keeping in mind to provide integrated solution. The AOPs are effective techniques to treat high degree industrial wastes. The aspects of depolymerisation and mineralisation were investigated. The variables studied have improved the degree of depolymerisation. Hybrid systems based on different techniques needs to be developed. These techniques have bright prospect in nearby future due to ongoing research initiatives. Best Available Technologies needs to be explored to supplement the conventional biological and chemical methods.
