Soil PS ®

Sludge Digester

In intensive aquaculture culture systems, feeding increases accumulation of organic matter in pond leading to higher oxygen demand at the mud-water interface and may cause production of Hydrogen Sulfide gas (H2S). Growth, survival of the shrimp and quality of pond water is greatly affected with pond sludge. Removal of sludge frequently from the pond bottom, the organic nutrients reduces from water and it affects the growth of phytoplankton and pond productivity. Large volume of accumulated shrimp waste will increase oxygen demand and cause oxygen depletion on the bottom that stress shrimp and more susceptible to disease. Also the undesirable gases produced from pond waste can affect the appetite of shrimp, increasing feed conversion ratio and leading to deterioration of water quality. To address the above problems, SOIL PS has formulated with following probiotic strains for decomposing the organic matter and minimising the H2S gas. SOIL PS has tested across the different aquaculture production sites and the validated the product.
