Leading Sewage Sludge Treatment Solution
1.
2. According to the 1996 protocol to the London Convention, dumping the
sludge to the ocean is no more allowed. Enbiocons offers a new solution
called "SAFE" (System for sludge as Advanced Fuel & Energy) for
thermal dry of wet Sludge. By removing moisture from sewage sludge,
we achieve dry granule less than 10% of moisture contents(over 90%
Dry Solid) and the size of granule is max. 20 mm dia. This process has
constructed and designed for dry capacity of 2,500 ton/day of sewage
sludge from Seoul, Gyeonggi-do, Incheon and Pusan, the population of
these regional local governments is about 27,000,000. The end products,
dry sludge, use for the auxiliary fuel of thermal power plants.
Why SAFE ?
•Rotary kiln equipped with the cutting blades
•Blades are designed heat resistant and wear resistant material
•Convection and Direct heating by hot air
•Reduce disposal cost through decreased weight and volume
"SAFE" ONE OF THE BEST SOLUTION
FOR SEWAGE SLUDGE TREATMENT
3. ▶ Advantage of Cutting Blades
•Cut the sludge into as small as possible to increase
the specific surface area and improve the water
evaporation.
•Using the cutting blades & high temperature flue gas
: dry the water of sludge surface using high
temperature flue gas to remove viscosity of sludge
for a short time and then crush the sludge lump
•Reducing energy cost
Function of Main Equipments
01Wet Sludge Storage Tanks and Gate
•This process consists of Sludge storage tanks, wet sludge supply pump and
hydraulic driving gate to prevent the diffusion of malodor.
•The pump is hydraulic piston type. It guarantees no blocking the piping.
•The odor around gate is collected and send to the hot air generator and burnt
away.
•The pump can be control the volume of supplying Sludge by control of piston work
02Dryer
•Simple and Safe operation
•Rotary kiln equipped with the cutting blades
•Two steps sludge cutting process enable to improve energy and dry efficiency
•No malodor spreading allowed
•As soon as input the sludge, cutting blades cut into small pieces.
•Explosion protect system

Heat sources
•Combined Direct and Indirect drying is possible
•The malodor is used for combustion air
•Designed for Absorbtion of combustion shock
Odor Control
•All odor generated from process, controled and minimized through 3 steps of odor control system.
•Odor control process consists of Wet scrubbing, Bio -filter and chemical scrubbing process.
▶ Wet scrubber works
•Direct cooling effect
•2steps cooling down
•Low-off gas causing condensing effect
▶ Bio Filter
•Reducing operation cost by Biological deodorization
•Low pressure drop
▶ Chemical scrubbing
•Remaining odor control
5. Stability
•Fast response to the fluctuations of sludge volume and property
•Optimized design for feeder and screw
•Enable to control the sludge supply by adjustment of piston work
Simplicity
•Easy to maintenance
•Outstanding durability
Dryer equipped Sludge cutting system
•High dry efficiency
•Corrosion resistance material applied
•Enable to Control the moisture contents of dry sludge
•Enable to control the detention time and input volume
•Odor from process burning away at heat generator
Heat recovery system and odor and dust control
•2 step cyclonic dust collector
•Flue gas heat recovery system
•4 Steps odor control
Advantage of SAFE process
