**4.5 Variation of COD values for htp-2 process techniques for desalination membrane fabric**

Due to depolymerisation the total organic load will increase in the reaction media depending on the efficiency of process technique adopted. The COD/TOC gives better estimate of the same. The **Table 2** shows the variation of observed COD values in 'ppm' at an accuracy of ± 5% for hydrothermal process based on alkaline hydrolysis techniques tried on desalination membrane fabric made of polyester. The COD values of up to 120 ppm was observed and shown expected trends.
