Use of Nano (Zeolite-Silica) composite for the Removal of Pollutants from Water and Soil for Freshwater Tilapia Aquaculture Production

The Central Luzon State University through the leadership of Dr. Juvy J. Monserate developed the Zeolite-silica Nanocomposite (ZNC) technology. The ZNC is a novel material synthesized and fully characterized at CLSU Nanotechnology R & D Facility.  ZNC can be utilized as soil and water conditioner for aquaculture purposes. Because of its enhanced properties: 262 m2 /g (surface area), smooth surface morphology (SEM), diameter size 38.26±8.32 nm, and amorphous – it is effective in purifying intensified aquatic water. It is slightly soluble, and is crucial to retain this amorphous quality to enable a sustainable energy system based on the recycling water in the ponds.

The nano (zeolite-silica) composite had improved the water quality and reduced heavy metal accumulation. Nano-char (nano-silica) and nano zeolite composites were able to reduce total ammonia-nitrogen (TAN) and total dissolved solids (TDS) in contaminated water. However, the experiment was tested in a laboratory condition.

Deterioration in water, mortalities due to disease, and fish kill outbreaks can be solved through the application of nano char (nano silica) technology for water and soil quality improvement in aquaculture.  The application will benefit the farmers such as a) reuse of water/recycling of water after harvest thus reducing the pressure towards our groundwater; b) healthier fish; and c) higher farmer income.
