Stripping Towers

Stripping Towers Relatively high levels of many organic contaminants can be reduced to well below WHO target levels by the stripping process which employs specially designed packed columns with new high-efficiency packing systems. VOCs commonly found include halogenated hydro-carbons and aromatic compounds such as benzene, toluene, ethylbenzene and zylene (BTEX compounds), and petroleum. Many of these have been identified as carcinogens and regulations now restrict their presence in potable water supplies to 'no discernable traces'. Activated carbon adsorption is a well established process to counter VOC contamination but the carbon is expensive and may need frequent regeneration. Air stripping is a highly cost effective alternative to adsorption. Energy consumption is normally modest and maintenance costs in typical installations are minimal. Stripping will typically reduce levels of 100mg'l to 5mg/l or below and the water can then be finally 'polished' with activated carbon. The carbon beds are thus protected from high levels of contaminant and will have a greatly extended life. Forbes Plastic Tanks
