The application of the BZT Waste Digester has improved the water quality tremendously and cut done aeration time and cost. We now applied it in all the ponds even where water quality seem manageable we still applied it. This is because the BZT Waste Digester converts all left over feeds into useful products for the shrimp to feed on. We are now relief of bad water quality management and focusing on the expansion of the farm. We also recommend the BZT Waste Digester to any shrimp farmer 100 % without any reservation for it application. CLICK link below to read the entire testimonial.
