1. Outstanding advantages of screw slurry press
The ESP – Eco Screw Press multi-disc screw press is a durable and highly effective device in the oil and grease sludge pressing industry such as aquatic sludge, fish pond sludge, plating sludge, food sludge, Press machine has many advantages over similar devices on the market such as:
- High durability when exposed to acidic environments (such as plating sludge, textile dyeing mud) or alkalizing (such as long-term food sludge, seafood sludge)
- Saving investment costs and replacing spare parts, low power consumption from only 0.8kw for 1m3/h model to 3.95kw for 10m3/h capacity
- Automatic control, the machine has an automatic cleaning system that does not need to be operated.
- Design and install according to customer requirements, combined with options for sludge drying / sludge transport
2. Structure and operating principle of the Screw Slurry Press
Sludge is pumped from the sludge storage tank or sludge settling tank or flotation tank to the flotation tank with a flow of 1 – 20 m3 /h (depending on the capacity of the machine). At the flocculation tank, the sludge is mixed with the polymer. Depending on the nature of the sludge, Polymer Cationic or Polymer Anion will be added to perform the flocculation reaction, the polymer flow depends on the polymer used and the amount of dry matter present in the sludge.
In the flocculation tank, there is a stirrer system, which ensures the contact between sludge and good chemicals, making the reaction process easier. The sludge after flocculation will be put into the screw press to perform the water separation process.
3. The internal structure of the screw slurry press manufactured by SVN is described as follows:
4. What kind of sludge is the screw slurry press suitable for?
– Organic sludge such as: sludge from food processing, aquatic sludge, sludge from livestock, sludge from domestic water treatment system.
– Inorganic sludge such as: sludge from textile dyeing, sludge from paper mills, plating sludge, plastic granule sludge, cosmetic sludge, ceramic tile mud
5. Sludge press capacity
Depending on production and business activities / tank volume / treatment system capacity to choose the right machine model máy
|Model||DS (kg/h)||Sludge flow (m³/h)|
|Low concentration||High concentration||10000mg/l||20000mg/l||25000mg/l||50000mg/l|
