Sludge Dewatering Screw Press developed by HOLLY utilizes the dewatering principles of force-water homo-direction, thin-layer dewatering, proper pressure and extension of the sludge dewatering path. The new equipment, more advanced than the traditional dewatering equipment which are easily blocked, unsuitable for low-concentrated sludge and oily sludge, of high consumption and difficult to operate, well eliminate these problems and are of higher efficiency and power saving.Features ♦ Enclosed to minimize odors and noise ♦ Very low wash water usage(1/8 compared with belt press) ♦ Very low power consumption(1/20 compared with centrifuge) ♦ High cake solids ♦ Minimal operator requirement ♦ Easy to operate and maintain ♦ Auto start-up, run and shutdown ♦ Touch screen operation optional ♦ Sludge Flow and Cake Monitoring System ♦ Available with many other options like Dairy, Palm Oil, etc.Typical Applications The Sludge Dewatering Screw Press can be provided with all equipment required for dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.Technical parametersModelDS standard capacitySludge treatment10000mg/L20000mg/L30000mg/L40000mg/L50000mg/LHLDS1316～10kg/h～1m3/h～0.5m3/h～0.4m3/h～0.3m3/h～0.28m3/hHLDS13212～20kg/h～2m3/h～1m3/h～0.8m3/h～0.6m3/h～0.56m3/hHLDS13318～30kg/h～3m3/h～1.5m3/h～1.2m3/h～0.9m3/h～0.84m3/hHLDS2019～15kg/h～1.5m3/h～0.75m3/h～0.6m3/h～0.5m3/h～0.4m3/hHLDS20218～30kg/h～3m3/h～1.5m3/h～1.2m3/h～1m3/h～0.8m3/hHLDS20327～45kg/h～4.5m3/h～2.25m3/h～1.8m3/h～1.5m3/h～1.2m3/hHLDS30130～50kg/h～5m3/h～2.5m3/h～2m3/h～1.5m3/h～1.4m3/hHLDS30260～100kg/h～10m3/h～5m3/h～4m3/h～3m3/h～2.8m3/hHLDS30390～150kg/h～15m3/h～7.5m3/h～6m3/h～4.5m3/h～4.2m3/hHLDS304120～200kg/h～20m3/h～10m3/h～8m3/h～6m3/h～5.6m3/hHLDS40190～150kg/h～13m3/h～6.5m3/h～5m3/h～4m3/h～3.2m3/hHLDS402180～300kg/h～26m3/h～13m3/h～10m3/h～8m3/h～6.4m3/hHLDS403270～450kg/h～39m3/h～19.5m3/h～15m3/h～12m3/h～9.6m3/hHLDS404360～600kg/h～52m3/h～26m3/h～20m3/h～16m3/h～12.8m3/hModelMain specificationDistance from        the ground(mm)Outline dimension(mm)Net weightOperating  weight(L)(W)(H)HLDS131Ф130×125018607401075250395HLDS132Ф130×225019608701075350595HLDS133Ф130×325019609201075450795HLDS201Ф200×135026507501375420540HLDS202Ф200×235026509401375550660HLDS203Ф200×33502650119013757001010HLDS301Ф300×1530344094018259001300HLDS302Ф300×253036401260182513502000HLDS303Ф300×353039001620182519002700HLDS304Ф300×453039002040182525003600HLDS401Ф400×166043501020216022004200HLDS402Ф400×266043501550216035006000HLDS403Ф400×366045702100216055008000HLDS404Ф400×466045702650216070009500ModelMotor powerWater pressure for cleaningWater consumotion        for cleaning(L/h)Maintenance periodScrew axisMixing machineTotalHLDS1310.1kw0.1kw0.2kw                              0.1～0.2Mpa      (no need high pressure washing  water)48                                                              5 minutes/dayHLDS1320.1*2kw0.1kw0.3kw96HLDS1330.1*3kw0.1kw0.4kw144HLDS2010.37kw0.37kw0.74kw32HLDS2020.37*2kw0.37kw1.11kw64HLDS2030.37*3kw0.37kw1.48kw96HLDS3010.75*1kw0.75kw1.5kw40HLDS3020.75*2kw0.75kw2.25kw80HLDS3030.75*3kw0.75kw3kw120HLDS3040.75*4kw0.75kw3.75kw160HLDS4011.1*1kw0.75kw1.85kw80HLDS4021.1*2kw0.75kw2.95kw160HLDS4031.1*3kw0.75kw4.05kw240HLDS4041.1*4kw0.75kw5.15kw320
