WHY SHOULD REPLACE THE OLD SLUDGE DEWATERING MACHINE TECHNOLOGY?
During more than 10 years of operation in the Vietnamese market, ARK has had the opportunity to interact with and understand the scientific progress in sludge treatment equipment. In recent years, many company have had to upgrade or replace old sludge dewatering machine with high-tech sludge dewatering machine.
Realizing that the old sludge dewatering machine are not capable of meeting the standards for sludge treatment, leading to a significant reduction in the treatment efficiency of the sludge dewatering machine. Compared with continuous maintenance and repair, investing in a new generation of high-tech sludge dewatering machine is a long-term cost-saving solution for investors.
Currently on the market there are 4 most popular types of sludge dewatering machine:
- Screw Press
- Belt Press
- Filter Press
In the past, Belt Press and Filter Press were often favored because of their product prices that were suitable for many investors. According to the trend of economic development, the increase in capacity or change in production technology makes the old sludge dewatering machine unable to meet the treatment requirements.
For two new generation sludge dewatering machine, Decanter and Screw Press, have partly overcome the existing disadvantages such as: polymer consumption, operating power, maintenance costs….
Each type of sludge dewatering machine will have different disadvantages that investors need to consider when choosing:
|DECANTER||SCREW PRESS||BELT PRESS||FILTER PRESS|
|Operating Time||24/24||24/24||24/24||4-5 hours/sludge batch|
The dryness of the mud cake is low.
High investment cost.
The operation makes a lot of noise.
Consumes a lot of energy during operation.
Few enterprises can produce in Vietnam.
Polymer is required during use.
High operating costs.
Consumes polymer to stabilize solution concentration.
The filter cloth must be changed and washed continuously; It takes labor to operate and clean the machine.
Multiple operators are required due to continuous operation.
Spare parts and repairs are expensive and unavailable.
The moisture content of residue (slurry cake) after pressing is very high.
Difficult to change shedding moisture of mud cake.
Non-continuous operation due to batch operation characteristics.
The machine needs a large installation area, occupying the area to place the machine.
The machine needs labor to operate and clean the machine.
Can be used with most sludges (including sewage sludge or manure sludge)
Types of organic sludge: Sludge is supplied from wastewater treatment plants of food processing plants. Seafood sludge, livestock sludge, sludge from domestic water treatment system.
Inorganic sludge such as: The sludge is collected from the wastewater treatment system of the textile dyeing factory. Paper mill waste sludge, plating sludge, plastic particle sludge, cosmetic sludge, ceramic tile mud.
Especially with special sludge such as: Mining mud (coal, metal plating, ore mines or difficult-to-press sludge) cannot be pressed with conventional sludge dewatering machine such as Belt Press or Filter Press.
Belt Press are used mostly in domestic wastewater treatment systems, or food, seafood, industrial, paper mills, brick, mines, food manufacturing plants. other products. (except for high viscosity slurries)
Treatment of sludge from wastewater in agro-forestry product processing
Inorganic sludge treatment, (e.g. semiconductors, metal circuits, rocks and ores, etc.)
Industrial chemical sludge treatment: bleach, textile dyeing, white titanium (TiO2), Calcium Carbonate, AminoAcid, ore industry, metallurgy…
Treatment of sludge in the food industry: Sugar, beer residue, sauces, drinks…
Separation of solids in the production stages of the food industry, alloys, inorganic compounds, iron and steel industry…
Even some large-scale livestock and poultry farms have used Filter Press to dry manure. Manure cake is used as a very effective fertilizer.
So, choosing a new type of sludge dewatering machine with new technology will partly solve the balance between sludge pressing efficiency and long-term investment costs.
