Multi disc dehydrator / Sludge drying, Recycling drying
There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, multi disc dehydrator performs dehydration and filtering with filtering devices configured by combination of moving discs and fixed discs put next to each other.
| ■ Multi disc dehydrator |
The filtering devices configured by several stainless discs are set upper and lower, and sludge is dehydrated while it is conveyed as the filtering device rotates.
The upper and lower filtering devices are set to make their interval narrower as it moves forward. By setting them with narrower interval, sludge is squeezed and dehydrated.
Filtering part is combination of moving disc and fixed disc and made to prevent sludge clogging. Therefore, although automatic flashing device are attached, amount of flashing water can be kept small.
In dehydration with this type of apparatus, sludge need to be turned into flocs by flocculation as much as possible during conditioning process since sludge flows out from gaps between moving disc and fixed disc together with water (filtrate) if it is not in flocs shapes.
Mechanism of multi disc dehydrator is to rotate filtering devices configured by combination of moving disc and fixed disc and to filter water from the gaps between the devices. Sludge need to be turned into flocs as much as possible though, this can be said as low maintenance and energy saving type of dehydrator which does not need power supply for vacuuming, pressing, etc.
About types of sludge dewatering / Sludge drying, Recycling drying
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.
| Please consider KENKI DRYER for drying of sticky materials, adhesive materials and materials in liquid state that no other dryer can deal with. |
| Initial, running and maintenance costs are low because of its simple structure based on internationally patented technology. |
| For sludge drying, costs of our dryers are estimated to be retrieved within 2, 3 years by reducing industrial waste disposal cost. |
| For raw material slurry drying, laborious works of manual operation will be decreased significantly by replacing box shaped compartment tray dryer with our dryer |
| In case of organic wastes drying, the waste can be recycled as fuel, fertilizer, soil conditioner and feedstuff after being dried. |
