SLS-MDW(Mechanical Dewatering Filter Press System)
Filter Press Dewatering System
- Filter press is the solid liquid separation system.
- 1st process is that the sludges are fed into in the chamber of filter plate by using the high pressure pump.
- 2nd process is the squeezing, de-caking and washing.
- Finally, dewatered cake is produced.
Common Specification
- Reduction of operation cost by automatic unmanned system.
- Squeezing dewatering by using the high pressure pump.
- Possibility to product the low water content sludge by secondary squeezing pressure(7∼20kgf/cm2).
- De-caking by the automatic filter plate shifter.
- High pr. washing equipment of filter media. - to protect the fouling and increase the life cycle of filter media.
- Use the filter plate with anti-corrosion and anti-friction.
- Frame body to use the SUS lining with rolled steel.
- Reduction of installation cost with applying the diverse standard.
- Low management expenses due to without system trouble.
- Protect the overload of system by using the torque guard.
- Little influence of sludge properties.
- Low solid content within Filtrate.
- Application - Water works and waste sludge
- Dye and pigment process sludge
- Livestock wastewater sludge
- Food process sludge
- Other process sludge

technology of Organic Sludge Dehydration
가축분뇨 슬러지 탈수 및 고체연료화
하수슬러지 탈수 및 재활용
열탈수시스템
SLS-MTDW(Thermal Dewatering System)
탈수원리
- 열원으로부터 케이크 층에 전도열 인가
- 탈수 케이크 층내 모세관에 부착되어 있는 잔류 여액을 내부 증발압력으로 배출
- 외부가압력(공급압+압착압) + 내부가압력(여액증발압)
- 케이크층에 열인가는 케이크의 비저힝성 감소시켜 탈수율을 향상시킴
장치특성
- Filtration Velocity(Capacity)는 원 슬러지의 유기물 함량과 관련이 있음
- Heat Source는 Steam와 Hot Water 모두 이용 가능
- 여액을 Hot Water로 재이용 가능
- 동절기 슬러지(유기물 함량 : 40 wt%)의 경우에도 함수율이 50wt%인 저함수율 탈수 케이크 생산가능
- 케이크의 최고 상승온도 : 70℃
- 케이크 박리 상태 양호
- 적용범위 - 상·하수 슬러지
- 염료/안료 공정 슬러지
- 축산폐수 슬러지
- 기타 공정 슬러지

주요장치 구성 및 특성
Construction and Characterization of Main Devices
| NO | DESCRIPTION | CHARACTERIZATION | APPEARANCE |
|---|---|---|---|
| 1 |  PLATE SHIFTING SYSTEM(여판이송장치) |
여과판을 이송하기 위한 이송블록이 모터에 의한 체인 정역구동으로
고장의 위험이 없으며, 과부하 검출장치가 부착되어 여과판 손잡이
파손 및 협착사고를 방지함으로써 높은 안전성을 보유하고 있습니다. 또한 순차방식에 의한 여과판의 이송은 1장부터 5장까지 탈수기의 사양에 따라 다양하게 선택이 가능합니다. |
 |
| 2 | CLOTH VIBRATOR (여포진동장치) |
여과포를 여과판 상부에 장착된 여포걸이장치에 설치하여 공기압에 의한 햄머의 수직력과 스프링에 의한 복원력에 의해 여과포를 10회 정도 진동시킴으로써 점성이 높은 케이크도 완전박리가 가능하여 여과포의 탈수효율을 극대화합니다. |  |
| 3 | CLOTH WASHING UNIT (여포세정장치) |
특수체인에 의한 수직 2단축 삽입식 구동으로 낮은 층고에서도 여과포
의 세정이 가능하며, 세정시 비산되는 오염원으로 부터 안전한 밀폐형
구조를 채택하고 있습니다. 또한 과부하 검출장치가 부착되어 여과포의 손상을 방지함으로써 높은 운전효율을 유지합니다. |
