Our product range comtains a wide range of Auto Chamber Filter Press, different models Belt Press, belt press, Wastewater Treatment System and dust collection machine
filter press: filter press is a highly efficient, compact, dewatering device for separating solids from liquid slurries in the form of compressed cake. Under the support of the strong r&d strength, doyen has developed and produced the manual, mechanical, hydraulic, program controlled automated membrane, quick opening types. In addition, doyen adopts advanced technology to develop a series of recessed, membrane and plate and frame filter plates, such as the high temperature and pressure polypropylene membrane filter plate, rubber membrane filter plate, high temperature filter plate and some special purpose filter plates. the doyen suspended plate transport systems, allow a perfect safe operation with minimum maintenance costs. Doyen systems have been designed to achieve the maximum free space for optimal manipulation and maintenance care of the filter plates. The opening and closing cycle is operated by a highly technically advanced automatic hydraulic unit. Together with the integrated automatic washing device, drip trays , automatic stop, as well as the automatic system for the filter operation through a plc program, brings us to the total security concept in continuous process. we offer a full range of membrane or recessed chamber filter press options from manual to fully automatic operation, from plate sizes 500 mm up to 2.0 m.
Complete closed water recycling system this system has a closed and continuous cycle and doesn’t request any water supply except for a quantity of about 2-4% of the total treated water due to the scattering and evaporation of the same in the production process, so that can maximum minimize the need of water coming from waterworks and save huge water. This system shall be perfectly fit for those medium and big factories with a lot of water need in production line (capacity from 600 lpm to 8300 lpm available). compact water recycling system this small compact system is specially designed for those small stone factories that would like a fully auto control system to handle their water treatment plant. This system includes everything in a compact package, such as slurry pump, dosing machine, silos, mud pump, mixing tank, filter press, control panel etc. So that it can save a lot of space and quite easy handling, as well as very environmental. It is available for those small factories with total water capacity smaller than 300 lpm. mud processing system with our mud processing system, they can ideally reach their goal. This system commonly includes chemical dosing machine, mud mixing tank, mud pump, filter press and control panel. This system is allowed to operate daily 4 to 8 hours depending upon the quantity of stone powder collected in the sedimentation tanks.
For sludge dewatering which need a pre-floculation: After mixing with the prepared flocculation in the dynamic and static mixer, the small particles solids in the concentrated sludge would form bigger size of flocculated sludge and the free water is separated. Flocculated sludge is conveyed to the belt then it further goes to the gravity dewatering area. Under the gravity, free water would fall on the tray, and the rest sludge would be nipped between two belts. Then it would further goes to the wedge zone for pre-filtration, and then to low pressure zone and high pressure zone through the decreasing diameter rolls. Under the extrusion and shearing force, the solid and liquid is separated. Finally filter cake with expected low moisture content is discharged.
