In recent years, the stacked-screw dewatering machine has also been rapidly developed, innovated and promoted in China.
With the characteristics of easy separation and non-clogging, the stacked screw dewaterer has been widely used in urban sewage treatment and industrial wastewater treatment, petrochemical industry, medicine, textile, metallurgy, food and beverage, mining and other fields.
In our daily use, the stacked-screw dewatering machine will find that the production efficiency is sometimes not very high, so how to improve its efficiency?
Let’s take a look at it.


First of all, we need to know its principle.
When a sludge dewatering machine works, it is generally the physical and chemical reactions of the sludge pressing process. Is the physical process primarily concerned with the press and drainage functions of sludge dewatering?
The phyto-reaction is the synthesis of the fine particles of sludge water into larger volume particles by means of coagulants and other chemical components to facilitate pressing and dewatering.
The main component is a flocculant, often called pam, which chemically aggregates the small particles in the sludge into large molecular flocs that enter the sedimentation and pressing process.


Here we should note that flocculants need to be used together with the dewaterer to be effective, and direct input into the effluent is not basically very effective.
Therefore, in order to provide the efficiency of the sludge dewatering machine, the flocculant needs to be put into use.


Of course, flocculants can be divided into many types, including inorganic flocculants and organic flocculants, of which inorganic flocculants can be divided into iron and aluminum based on metal salts, modified cations, cationic organic, and various acryloyl type cations.
Different types of flocculants have different effects in different types of sludge water, so different flocculants should be added according to the nature of sludge water to achieve better results.
