Scale Control Agents

The need for scale control agents

Scale formation occurs in different areas of the pulp making process.

These include the digester heater, screens in washing, filters, drums (plugging) in washing / bleaching, along the pipe lines, control sensors, liquor evaporator, vacuum pumps, scrubbers and tanks surfaces. These could lead to significant negative impact on productivity and product quality.

Scale control agents inhibit the formation of scale on equipment’s surface, pipe lines, control sensors, vacuum pumps etc., thus ensuring optimum efficiency.

Scale control agents could be applied to all areas defined above or at any other areas of which scale formation may take place, including paper machine equipment such as screen, head box slice, showers, vacuum pumps etc.
