This product is suitable for continuous and uniform conveying of loose, sticky and easily wound materials, the temperature of conveying materials is up to 100, the maximum inclination Angle is less than 30
Lamella clarifier also called inclined plate sediment tank. It is good at high efficient combined type settling tank; set many dense inclined tube packing to make the suspended impurity in water sediment, water rise flow along inclined tube, the separated sludge down to the tank bottom along the inclined tube by gravity, then discharge it in concentration. Such tank can improve sediment efficiency 60 70%, it can improve treatment capacity 3 5 times in the same area. It can design different flow rate inclined plate sediment device according to raw waste water test report, it need dose flocculant usually.

Multidisc are arranged one after other with alternate disc being moving and fixed.
The gap between the plates acts as media for fine filtration.
The screw press main unit requires very very low power motor and the filtration surface area consists of a multiple discs which are self-cleaning, and generally do not clog,thus, the sludge press can be used continuously.The main unit of the sludge dewatering screw press is of multi-shaft design. Hence,
when two or more main units are configured into one machine, any individual shaft can be repaired or serviced without interrupting operations.
The screen ladder grille is mainly composed of the main components such as the driving device, the frame, the traction chain, the screen plate with the lifting ladder, the washing system and the electric control system. The drive motor is installed on the main shaft in the positive direction of the frame. Driven by the transmission chain, the mesh plates on both sides will extract the dirt trapped within its length from bottom to top. When it reaches the upper part, it will pass the steering function of the sprocket. Under the action of the flushing water of the top flushing device, the unloading work is automatically completed.
The drive device of the mesh plate ladder grille is located on the upper part of the frame, which is an imported brand SEW shaft-mounted reducer. Screw-type adjustment devices are installed on the front and rear sides of the frame to adjust the tightness of the transmission chain.
The frame of the mesh plate ladder grille is an integral cuboid rigid structure assembled and welded by stainless steel plate and section steel. A water inlet hole is opened at the water-facing end of the lower part of the frame, guide rails are arranged on the front and rear walls of the frame, and an internal slag collecting groove is also arranged on the upper part of the frame, which extends to the outside of the machine. The rack is installed in the grid well, and the gap between the two sides of the rack and the grid well is the channel for the filtered water from the grid. Diversion baffles are arranged on both sides of the water-facing end of the rack, which can prevent floating garbage from passing through while diverting.
The feed product is pumped into the decanter centrifuge through an inlet. Feed into a horizontal bowl and then rotate. The bowl consists of a cylindrical portion and a conical portion. The separation takes place in the cylindrical part of the bowl. Fast rotation produces centrifugal forces of up to 4000 x g. Under these forces, solid particles with a higher density are collected and compacted on the wall of the bowl. The scroll (also a screw conveyor or screw conveyor) rotates inside the bowl at slightly different speeds. This speed difference is called a differential speed. In this way, the scroll conveys the precipitated particles along the cylindrical portion of the bowl to the conical end of the bowl. At the smallest end of the conical portion of the filter bowl, dehydrated solids leave the filter bowl through the discharge port. The clarified liquid exits through the mating disc (internal centrifugal pump).
Submersible mixers are suitable for promoting and stirring sewage containing suspended solids, thin mud, industrial process liquids, etc. in the process of sewage treatment plants, creating water flow, strengthening mixing function, and preventing sludge sedimentation. It is an important process in municipal and industrial sewage treatment processes. equipment. QJB type submersible mixer
The static screen has a built-in screen. The screen consists of a horizontal bar with a special profile and is made of Aisi 304 or 316 quality stainless steel.
The water is distributed in the upper part of the filter screen, and its inclination on the horizontal surface gradually decreases from top to bottom. The effect of solid matter separation and dripping is obtained sequentially.
The unit technology uses extremely small air bubbles to lift suspended solids and oil to the top surface. The formed sludge layer is scraped into a sludge holding tank. The addition of coagulation and flocculation chemicals may be required to enhance the performance.
Removal efficiency is usually superior to gravity bases systems and often applied as polishing step (downstream of CPI)
The unit can be supplied with a gas-tight cover, coagulation & flocculation dosing and mixing equipment and air-saturation by special pumps or in separate pressure vessel.
Flotation consists of separating solids from the water phase by attaching the solids to fine air bubbles to decrease the densityof the particles which float instead of sinking. The rising solids are called the and are skimmed off the surface and further processed in the sludge train.Chemicals can be added to improve the separation: first for coagulation and then for flocculation.
The type of flotation used by Dissolved Air Flotation in which the suspension is saturated with air at high pressure. Bubbles are released to the water and will attach to the suspended solids.The bubbles from a system are much smaller than in other types of flotation systems and better adhere to the solids.This makes
one of the most efficient flotation options of wastewater treatment.
PAM Polymer Preparation Unit Description
The automatic dosing machine is widely used in the waste water treatment, it can mix the compounds continuously and effectively, so the reactive polymer solution appears. These main components of the machine: Polymer feed machine (including material hopper), Dry powder infiltration device, Tank, Level controller, Mixer, Dosage water inlet pipe, Electric control panel.
Polymer dosing device
Polymer dosing device is composed of hopper, push screw, electric heater and etc. The effective volume of the hopper can meet the dosage for a long time which is equipped with sight glasses for observing material level monitored by the dry powder level meter. The push screw driven by the high-precision reducer can satisfy the dosage. The electric heater can be installed in the discharge pipe of push screw, and it can prevent the powder from caking.
Polymer dissolving device
Polymer dissolving device is composed of pre-soaking device, tank, and 3 sets of mixers. The pre-soaking device is to infiltrate and mix the polymer powder in advance. The 3 tanks are precast mixing tank, homogeneous slaking tank and solution storage tank, in which there is a mixer correspond to guarantee the homogeneity.
Water supply device
Water supply device is composed of pipeline, manual ball valve, filter, pressure gauge, solenoid valve, stop valve, and the rotor flow meter, etc.
