Drying of chemical factory sludge / Test cases / Sludge drying, The costs reduction

Drying of chemical factory sludge / Test cases

• Material to be dry: Chemical factory sludge
• Purpose of drying:The costs reduction of industrial waste disposal
• Moisture content: 80％W.B. before drying,  10％W.B. after drying
• Requirements for dryer: No clogging inside of the dryer since materials being dried are adhesive. 24-hour unattended operation. 
• Test result: OK

Water in the sludge thickened in the sludge thickener tank are removed at dehydration process to a certain degree.
However, moisture content is normally more than 80% and the sludge still has adhesiveness and stickiness. Also, latter processes are not easy because of influence of flocculants. Our drying apparatus of KENKI DRYER with international patented technology can surely dry any sticky, adhesive and viscus sludge, and also materials in liquid state like slurry, without clogging inside of the dryer. Also, because of its simple structure, its price is low and apparatus cost of the dryer can be retrieved by reducing industrial waste disposal cost within 3 years. Dried materials can be recycled as fuel, bacterial fertilizer, soil conditioner, etc. since component of the material is hardly changed because of its low-temperature drying method.
It can be applied to a system with pyrolysis apparatus as well.
