Screw Sludge Thickener IntroductionScrew sludge thickener has the advantages of high efficiency, low power consumption, fully automatic control and stable operation. It can directly and continuously concentrate the sludge in the secondary settling tank, and the concentration of sludge after concentration and separation is in the range of 90%-96%. It is stable and adjustable. After using the screw sludge thickener, it is not necessary to build a special concentration tank, thereby reducing the capital investment and saving the floor space, reducing the odor and phosphorus release from the sludge in the concentration tank, and reducing the workload of subsequent sludge dewatering. The processing capacity of sludge dewatering or deep dewatering equipment is greatly improved.Screw Sludge Thickener Work ProcessScrew sludge thickener is a thickening device, main parts consist of fixed rings, moving rings and screw shaft. The small movable filter joint formed between the fixed ring and the moving ring facilitates the filtration of the filtrate. The flocculated sludge particles are present in the chamber formed by the screw shaft and the ring piece, and the thickened sludge is discharged from the sludge port. The screw shaft is rotated and pushed to continuously move the moving ring  to prevent blockage.Screw Sludge Thickener FeaturesSimple process ,high efficiency ,power saving ,low investmentProgramme setting makes the operation convenient and accurateAccurate chemical preparation and dosage saves much operation cost .Screw Sludge Thickener ApplicationMunicipal SewageSlaughter HouseMetallurgical  Industry Wastewater Oily WastewaterPrinting  & Dyeing SewageMetal-Processing SewageMining Stone WastewaterElectronic Sewage

Sludge Dryer IntroductionECOPRO sludge dryer is an indirect heating low speed agitating dryer. There are two or four hollow rotating shafts inside the equipment. The hollow shafts are densely arranged in parallel with the fan-shaped wedge-shaped hollow blades. The structural design is particularly clever. The relative rotation of the shaft body utilizes the principle and structure of the same angular velocity and different linear velocity to skillfully achieve the self-cleaning effect of the sludge on the shaft body, thereby maximally preventing the phenomenon of "holding the shaft" during the sludge drying process. The sludge dryer quickly rushes through the “adhesive phase” during the drying process. At the same time, the ingenious structure makes the sludge reach the bidirectional shear state during the drying process. The dried sludge is continuously and continuously fed into the feeding port of the dryer by the screw feeder. After the sludge enters the body, the sludge is turned over and stirred by the rotation of the blade, and the heating interface is continuously updated to contact the body and the blade. It is heated sufficiently to evaporate the surface moisture contained in the sludge. At the same time, the sludge is conveyed in the direction of the discharge port with the rotation of the blade shaft in a spiral path, and the stirring is continued during the transportation, so that the water oozing out from the sludge continues to evaporate. Finally, the dry and uniform sludge is discharged from the discharge port. The jacketed shell structure is adopted, so that the sludge is uniformly heated at various interfaces inside the machine, the shaft body rotates, the sludge does not churn in the equipment, and the heated surface is continuously refurbished. Thereby, the steaming efficiency of the device is greatly improved, the purpose of sludge drying is achieved, and the low-cost operation of the whole device is realized.Sludge Dryer Work ProcessAfter the sludge is conveyed by the screw conveyor to the feeding hopper, the stirring device in the hopper is first stirred and crushed, and then transported by the double-axis screw device. After the sludge is transported to the drying cylinder, the lifting and lowering is carried out by the lifting cylinder. The belt is brought to the top, and due to gravity, it falls on the high-speed rotating crushing shaft and is quickly broken into small particles, thereby increasing the specific surface area and being quickly dried. This cycle of motion continues until the sludge is discharged.Sludge Dryer Advantages Completely solve the bonding problem High drying efficiency and increased processing capacity The product has strong controllability and wide application range. Easy to operate and easy to maintain Low operating costsSludge Dryer Application1. Breeding and slaughtering wastewater2. Hotel, restaurant, sales market, agriculture and other sewage3. Industrial wastewater from food, textile, printing and dyeing, chemical, leather, paper, glass, clay, rubber, etc.

Sludge Feeding Pump IntroductionThe sludge feeding pump is a conveying machine for discharging high viscosity concentration sludge. The sludge feeding pump is generally used for the transportation of sludge before dewatering. For the sludge dewatered by the filter press, belt filter, screw press, sludge thickener and centrifuge machine, the sludge pump is generally used.Sludge Feeding Pump Work ProcessThe sludge feeding pump is based on a twisted-leaf rubber cam rotor pump. The two spiral cam rotors that are continuously rotating under the synchronous gear drive are used to push the conveying medium from the inlet of the pump to the outlet of the pump, due to the rotor rubber impeller and the pump body. With perfect sealing, the pump's inlet and outlet chambers are completely partitioned and have a strong vacuum pumping capacity, so the pump's self-priming capability far exceeds that of other configurations. Due to the three-bladed 60° spiral rotor, the instantaneous design flow rate of the pump at each moment of rotation is constant with almost no pulsation and disturbance.Sludge Feeding Pump Advantages1. Compared with the centrifugal pump, the single screw pump does not need to install the valve, and the flow is a stable linear flow.2. Compared with the pneumatic diaphragm pump, the single-screw pump can transport various mixed impurities containing gas and solid particles or fibers, and can also transport various corrosive substances.Sludge Feeding Pump ApplicationsØPetroleum industry: heavy oil transportation, oil and gas mixed transportation, oil and water separation and waste oil recovery system, sewage treatment, polymer transportation.ØChemicals and pharmaceuticals: all kinds of pastes, emulsions,  suspended solids, gas, solid liquids, media that can not be stirred and sheared.ØEnvironmental engineering: various sewage transportation, dewatered sludge transportation, measurement and addition of flocculant and its chemical preparations, oil-water separation and exhaust gas desulfurization.ØMineral mining engineering: production equipment for coal water slurry equipment and transportation, titanium dioxide, kaolin, calcium carbonate, etc., spinning fluid, filter feeding, chemical dosing, charging and grouting, electrolyte treatment.ØFood industry: dairy products, juices, purees, vegetable sauces, meat clams and condiments, beer and brewing.Ø Paper industry: mud pumps for raw material equipment, coating and coloring processes, stoichiometry, slurry and wastewater treatment.

Static Mixer DescriptionStatic mixer is a device for the continuous mixing of fluid materials, without moving components. Normally the fluids to be mixed are liquid, but static mixers can also be used to mix gas streams, disperse gas into liquid or blend immiscible liquids. The energy needed for mixing comes from a loss in pressure as fluids flow through the static mixer. One design of static mixer is the plate-type mixer and another common device type consists of mixer elements contained in a cylindrical (tube) or squared housing. Mixer size can vary from about 6 mm to 6 meters diameter. Typical construction materials for static mixer components included stainless steel, polypropylene, Teflon, PVDF, PVC, CPVC and polyacetal.Static Mixer AdvantagesMaintenance-FreeFast and complete reactionMinimum space requirementNo orderLow investment cost

Inorganic coagulant is added and stirred to produce flocs. Sludge reacted with the inorganic coagulant is transferred to the metering tank by the sludge pump from where it flows to the flocculation tank.2. The sludge flows into the dewatering drum from the the flocculation tank .The rotation of the screw forces the flocs to slowly flow down to the thickening zone. The flocs are thickened by gravity. The filtrate separated in the thickening zone is returned to the oxidation ditch. 3. Thickened sludge moves to the dewatering zone. the gaps between the rings and screw pitch gradually narrow, thereby, increasing the pressure and encouraging the dewatering process.4. Since the moving rings continuously comb the gaps in the dewatering drum throughout the thickening and dewatering process, clogging is avoided and therefore cleansing water is not required.5. Solid substances separated in the dewatering process are also combed out and are automatically washed away using a timer controlled-shower. The solids flow back into the sludge tank, returned to the thickening and dewatering process.The inner pressure increases further, as the end plate blocks the flow. This encourages further dewatering of the sludge which is finally discharged as sludge cake.Screw Press Superiority (1)Small foot print  ECOPRO Sludge Dehydrator can be installed in places where placement would not be possible with other technology .
