Solid Settling Agent

Settling is the mechanism by which particles settle down at the bottom of a liquid and form a sediment. Particles experience a force, either due to gravity or due to centrifugal motion and move in a uniform manner in the direction exerted by that particular force. For gravity settling, this means that the particles will tend to fall to the bottom of the vessel, forming a slurry at the vessel base. Settling is an important operation in many applications, such as mining, wastewater treatment, biological science and many more industries. Solid Settling Agent settles down the undissolved solid particles at the bottom of the mixture container so that those particles can be separated easily whenever required. Basically, it makes the mixture impurities free and readies down for the next stage. Due to external interference sometimes, unwanted solid particles enters the crude mixture while getting transported, hampering the quality of the crude. Since the solid particles can be anything that may change the property of the fluid, it is important to remove those external particles. Solid Settling Agents execute this operation to maximum rate making the crude free from contaminants.

Functions of Silver in ALSTASAN SILVOX

Oligo-Dynamic Function 
Silver shows oligo-dynamic effect or toxicity on bacterial cells even in relatively low concentrations. Silver ions denature enzymes of the target cell or organism by binding to reactive groups, resulting in their precipitation and inactivation. Silver inactivates enzymes by reacting with the thiol groups to form silver sulphides.

Stabilizer function
Hydrogen Peroxide is not stable which means that it decomposes to oxygen and water. To solve this problem silver is added to hydrogen peroxide as
stabilizer. This stabilizer prevents the slow decomposition of the hydrogen peroxide. The Ag2+ ions keep O2- ions.

Activator Function
The silver performs as an activator. The singularity of this silver activator is that it only activates the peroxide when it is exposed to biofoulants. In contact with microbes the silver loses its stabilizing function and activates to release nascent oxygen to oxidize the exposed microbes. When all bacteria have been oxidized by the generated active oxygen compounds, the silver acts as stabilizer for the remaining and non-reacted oxygen.

Key Features and Benefits

  • Faster settling of muds because of good floc formation.
  • Clearer juice because of its high turbidity removal efficiency.
  • Lower moisture in mud-cake because of dewatering effect.
  • Less turbid filtrate because of better mud control.

Handling Measures
and Precautions

Proper human safety products such as splash goggles, lab coat, vapour respirator, NIOSH approved gloves and boots should be worn while handling and applying chemicals. Splashes on the skin should be washed off with water immediately. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. Should not be injected.


ALSTASAN SILVOX is an oxidizing product and should be stored in original vented containers, away from heat, direct sunlight and combustibles. Store in a cool and dry place. Please refer label and SDS for details.
