DEWATERING REVOLUTION

Advancing the technology to improve environment DEWATERING REVOLUTION Since 1992 Advancing The Technology For Better Tomorrow ACE KOREA INCORPORATION CO., LTD.

AN AWARD - WINNING (Excellent Machine - EM official certificate) superior quality of wastewater sludge dehydrator ELODE, the world's first field-proven coercialized electro-osmosis dehydrator which treats all types of wastewater including municipal sewage, paper-mill wastewater, food wastewater, livestock wastewater, wastewater from dyeing, wastewater from painting, chemical wastewater, pit wastewater, etc. ELODE extracts both free and absorbed water from the sludge producing a final dehydrated product with a moisture content of less than 60% (i.e. greater than 40% dry solids content). This ensures maximum dehydration performance with minimum environmental impact. ELODE can be installed as a complete system or in addition to an existing sludge treatment system. With more than 1 years of dedication, we are constantly applying the latest technology in equipment design to continuously improve our environment. This focus helps us design and manufacture the most efficient and best performing equipment.

ELODE Phase Electro-Osmosis Dehydration Equipment Methods of Dehydration by ELODE ELODE is based upon a technology allowing highly efficient dehydration to take place by extracting free water and absorbed water from sludge using electrophoresis and electro-osmosis. It is distinguished from conventional dehydration methods which only extract the free water from liquid sludge by applying high pressure and consuming large amounts of coagulation and flocculation polymers. Dewatered sludge cake is fed between the anode drum and cathode caterpillar of the ELODE machine. A three phase alternating current (AC), converted to direct current (DC) is applied to the anode drum and cathode caterpillar creating an electrical potential difference. This leads to a strong migration of sludge particles to the anode drum and water to cathode caterpillar. Thus, highly efficient dehydration with a water content below 60wt% is achieved. ACE KOREA INCORPORATION CO., LTD. / 4page

Electro-Osmosis Process of ELODE 1) Early Electro-Osmosis - Electrophoresis In the initial stages of electro-osmosis process, sludge particles (-) are strongly pushed to the anode drum (+). 2) Intermediary Electro-Osmosis Dehydration through movement of water (+) to cathode (-) 3) Final Electro-Osmosis - Capillary Pressure Forces the absorbed water flow through porous solid to cathode (-) 4) Cell Membrane Destruction Discharges the absorbed water (bonded moisture) of sludge ACE KOREA INCORPORATION CO., LTD. / 5page

SELO - Single ELODE For 2nd Stage Dehydration SELO, Single ELODE is a compact second stage dehydrator using Electro-Osmosis to further dehydrate sludge cake from conventional dewatering equipment. This produces a drier sludge and significant reductions in sludge weight. It can be easily be integrated into any conventional dewatering system such as belt-press, filter press, decanter (centrifuge), gravity dehydration etc. The sludge must be thickened to 95wt% moisture content or less by conventional means before it can be treated by SELO.

BELO - Belt Press Built-In ELODE For New Setup BELO, a highly efficient dehydrator that combines first stage mechanical dewatering by Belt-Press with second stage Electro-Osmosis. This is a highly effective process which reduces the final sludge cake dryness to or below 60wt% moisture content (a dehydration ratio of over 40%). This means the volume of the sludge is reduced to less than 10% of the input sludge and 50% less than conventional dewatering equipment. BELO is a compact and robust machine, where low noise, ease of operation, flexibility and low maintenance are critical.

Features and Benefits ELODE, a proven cost-effective electro-osmosis dehydrator designed to overcome the deficiency of conventional dewatering equipment and expensive thermal dryers. Conventional means of dewatering simply do not dehydrate sludges efficiently which rely on mechanical force alone. Dehydration by ELODE iediately after sludge dewatering significantly improves the dryness of the final sludge product. Thermal drying is another coon process used to increase the sludge dryness after the conventional dewatering. Thermal driers have a very high setup and operating cost in terms of energy consumption. ELODE effectively improves the dryness with a lower operating cost, approximately 70% to 90% of energy saving! Representative References HYUNDAI KIA MOTORS GROUP. KOREA. GROUP. KOREA. SAMSUNG GROUP.
