Belt press dehydrator / Sludge drying, Recycling drying
There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, belt press dehydrator holds sludge in between two filtering clothes and dehydrates by squeezing and filtering it.
|■ Belt press dehydrator|
Belt press dehydrator has a structure in which two filtering cloth hold sludge in between them and moves forward by going through many rollers. Sludge generated during wastewater treatment is conditioned by flocculants and shaped as floc after being condensed. Sludge in floc shape are injected in between two filtering clothes and tightened, then moved forward by keeping that state. Sludge between the filtering clothed is dehydrated by being squeezed and filtered while it passes through rollers which are set in various positions. Dehydrated sludge cake is peeled off by scraper and discharged when the two filtering clothes leave each other. After the dehydrated cakes are peeled off, the filtering clothes are cleaned by pressured water, then holds sludge again and re-enters to the dehydration process.
As flocculants, polymer flocculation for one-pack type and inorganic plus polymer flocculation for two-pack type are used.
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.|
No more trouble. Conveyor, Industrial environmental equipment and apparatus
A pyrolyser with internationally patented technology which use no fire
