In today’s wastewater treatment systems , the sludge press is a device that is applied in the final stage to reduce the weight and volume of sludge. The use of sludge presses to filter sludge will help investors save time and costs of sludge treatment.
Therefore, the sludge press is the most optimal sludge treatment today. In Vietnam, there are currently 3 lines of mud presses trusted by domestic investors, each of which has advantages to suit the needs of use.
SCREW PRINTING MACHINE
One of the most popular slurry presses by investors in Vietnam and around the world is the multi-disc screw press . This is the optimal solution capable of handling many different types of sludge.
Multi-disc screw press has the ability to work continuously 24/7, the device is suitable for handling high viscosity, dilute sludge, which can be mentioned as food industry sludge, farming industry sludge. aquatic products, livestock, algae, textiles, dyes, mud for cosmetic production, ceramic tiles, chemical production, plating… The sludge after being processed by screw presses will reach a low moisture content of 60 – 80%.
KS Boiler screw slurry press is highly appreciated for its quality. The device is made of full stainless steel material, anti-corrosion. Using a screw slurry press will reduce operating costs, the equipment is extremely compact and stable.
PRINCIPLE OF OPERATION
The screw slurry press researched and manufactured by KS Boiler uses the principle of dewatering by water pressure in the same direction, dewatering the thin layer, accurately compressing and expanding the path of the dewatering sludge.
When the wastewater is loaded into the tank, the screw is both responsible for transporting and rotating and squeezing the raw materials together to squeeze the water until the raw materials stick to residue and dry completely, the screw will push this material again. pass through the slot of the screw to fall out according to the trough installed at the outlet of the machine.
With advanced screw mud press manufacturing technologies, KS Boiler has completely overcome the disadvantages compared to traditional screw mud presses such as jams, can’t handle liquid sludge, no cleaning system. screw generator. With their efforts, engineers have invented a series of screw machines to help investors save power consumption, integrate automatic screw washing system, automatic control without operator, Discharge sludge at fixed position.
Conveyor belt slurry press is a line of slurry presses that has been around for a long time in Vietnam. The brand is widely known to investors. The conveyor mud press has a fairly compact design, the sludge after pressing reaches a moisture content of 60-80%. The equipment is manufactured with 304 stainless steel material, so it allows good operation in environments with high temperature and pressure, anti-corrosion, anti-rust.
The machine is equipped with a centrifugal system to separate the water to help concentrate the sludge before pressing, and the multi-stage conveyor design saves considerable installation space. In addition, a pneumatic automatic conveyor belt alignment system is designed. Conveyor belts are selected and imported from Europe, durability, good permeability, long life.
PRINCIPLE OF OPERATION
Conveyor belt slurry press is a device that presses slurry by mechanical pressure. Diluted sludge is flocculated and flocculated to improve water separation before being put into the conveyor belt press. The sludge after flocculation is pumped and transported to the auxiliary conveyor of the machine. Here, the sludge is evenly distributed on the conveyor and under the effect of gravity the sludge will be preliminarily dewatered and the solid sludge concentration will increase from 1 to 3%. The length of the auxiliary conveyor is from 1-2m depending on the design.
Next, the slurry is clamped between two conveyors and compressed by a roller system that rotates around the shaft. Water will be gradually removed when the conveyor belt passes through the low pressure compression zone to the high pressure compression zone (Pressure pressure depends on the diameter and density and the layout of the rollers). Towards the end of the compaction process, the sludge reached high dryness with solids concentration >25% and sludge volume decreased >10 times.
The residue after pressing is separated from the conveyor by a sludge scraper system designed at the end of the machine and washed by a system of high-pressure nozzles to continue the process of separation and filtration. Conveyor slurry press runs automatically and continuously with automatic pneumatic conveyor belt alignment system.
FRAME FRAME BULKING MACHINE
Compared with the above two mud presses, the plate frame mud press is the oldest equipment in Vietnam. This is also one of the highest rated machines in terms of quality. The moisture content of sludge after pressing reaches the lowest humidity in all current mud presses of 20-40%.
The plate frame mud press has a fairly simple structure, including many filter plates covered by a filter cloth. Optional plate frame capacity that the number of filters will change. The filter plates will be compacted to form many filter chambers containing sludge.
Plate-frame slurry presses have many types, automatic plate-frame slurry press, semi-automatic plate-frame slurry press, round-frame slurry press, plate-frame slurry press, capacity range from 500 x 500 mm to 2000 x 200mm.
The equipment can press many different kinds of sludge, mainly used in industrial wastewater sludge treatment, kaolin sludge treatment, ceramic tiles, ceramics, qiawngj filtration, minerals. Pressing to filter chemicals and sludge in the food industry such as: oil refining, rice flour, fish sauce, coffee filter press, soybeans, fruit.
PRINCIPLE OF OPERATION
The plate frame mud press works on the principle of using a combination of pressure and compression to reduce the volume of the liquid. The operation cycle of the plate frame slurry press is fully automatic and takes place in a fixed sequence including the following steps:
Step 1: The sludge pump system automatically pumps the liquid to the next part of the machine
Step 2: The machine automatically blows air, creating pressure and compression to squeeze and separate the water from the sludge through the filter cloth.
Step 3: Automatically open the door to let the sludge after it has been pressed to separate the water.
Sewage removal of sludge from the machine can be done manually or automatically before the machine operates for the next batch of sludge.
The European technology-based mud press is specially designed to be suitable for many different types of sludge and wastewater. This type of machine is widely used in many industries in Vietnam such as coal mining, mineral extraction, industrial chemical plants, wastewater treatment plants, ….
Plate filter presses as well as other types of mud presses help separate solids from liquid solutions. Finished sludge after the separation process can be buried or used for different purposes.
In the current wastewater treatment system, the choice of sludge press depends on the nature and type of sludge. Therefore, investors should consider carefully and choose the most suitable mud press.
KS Boiler is a leading mud press manufacturer in Vietnam, having many years of experience in researching, manufacturing, and installing mud presses in wastewater treatment systems, the engineers here understand the characteristics of the sludge dewatering system. , the specific characteristics of the sludge of each different industry, with each different industry will have different sludge treatment methods.
