In view of the high moisture content of mud cake and the poor dewatering effect of filter press, it is very important to choose the right sludge conditioner. Here are some suggestions and drug recommendations:

Agent type selection:

Inorganic sludge conditioner: such as polymeric iron, polymeric aluminum and other inorganic salt compounds, can effectively reduce the moisture content of sludge.

Organic sludge conditioner: such as polyacrylamide (PAM) and other polymer, through the adsorption bridge, so that the small particles in the sludge into a larger flocculent, improve the dewatering performance of the sludge.

Composite sludge conditioner: Combining the advantages of inorganic and organic conditioners, it can not only rapidly reduce the moisture content of sludge, but also improve the dewatering performance of sludge.

Pharmaceutical characteristics and effects:

Inorganic conditioner: usually low cost, large amount of addition, but the dehydration effect is more significant. For example, the use of inorganic salts such as polymeric iron and polymeric aluminum can significantly reduce the moisture content of the sludge.

Organic conditioner: The amount added is relatively small, but the dehydration effect is better. Polymer such as polyacrylamide can significantly improve the dewatering efficiency of sludge and shorten the treatment period.

Compound conditioner: Combining the advantages of inorganic and organic conditioners, it can reduce the treatment cost and improve the dehydration effect.

Recommended medicine:

For mud cake with high moisture content: composite sludge conditioner or organic sludge conditioner is recommended. These agents can reduce the moisture content of sludge more effectively and improve the dewatering effect.

Specific choice: According to the nature of the sludge, treatment objectives and economic conditions, you can choose the combined use of ferric chloride/aluminum + lime, or polyaluminum chloride + polyacrylamide and other combination programs. These combined schemes have been proved to reduce the moisture content of sludge effectively and improve the dewatering effect in practical applications.

Note:

When using sludge conditioner, attention should be paid to the dosage, method and time of the agent to give full play to its effect.

At the same time, it is necessary to check and clean the filter press regularly to ensure its normal operation and dehydration effect.

In summary, in view of the problems of high moisture content of mud cake and poor dewatering effect of filter press, inorganic, organic or composite sludge conditioner can be selected to improve. The specific choice of which agent needs to be comprehensively considered according to the nature of the sludge, treatment objectives and economic conditions.
