Mechanical treatment of sludge dewatering
Sludge dewatering is the technique of casting off water from semi-solid wastewater sludge produced in the technique of wastewater treatment. For wastewater treatment, sludge dewatering is vital to limit the quantity of sludge and make it less difficult to treat, transport and dispose of or in addition treat. Sludge dewatering is the system of keeping apart the stable and liquid factors of sludge. Sludge is a spinoff of wastewater remedy to minimize its quantity and make it less difficult to deal with and dispose. This method normally makes use of mechanical methods, such as a sludge dewatering machine, to get rid of water in sludge and produce drier and extra stable materials.
There are many kinds of sludge, and the classification is additionally rather complex. At present, we can typically classify sludge in accordance with the following.
According to the supply classification, it is nice to understand it, which can be roughly divided into three categories: water grant sludge, home sewage sludge, and industrial wastewater sludge. Domestic sewage can additionally be similarly categorized in accordance to therapy methods. Industrial wastewater sludge can be categorized in accordance to its source.
Various sorts of sludge have exclusive adaptability to the dewatering machine. At present, the commonly used models of sludge dehydrator are:, filter belt type, spiral ring kind, and plate body type. The decision and percentage of flocculants are additionally key to the dewatering of precipitated sludge. The flocculation impact is proper and the dewatering of sludge is rather smooth.
What are the advantages of a sludge machine?
1. Wide adaptability
There are many types of sludge, and the nature of sludge is also divided into many types. Oily slaughtering sludge, printing and dyeing sludge and other sludge that are not easy to flocculate and dehydrate can be used for dehydration, and 85% water content is not a problem.
2. Small size, low automation requirements
The full-automatic operation does not require too complex monitoring data, only the level of the sludge tank! The structure is simple and easy to maintain. The more sophisticated the equipment is, the more durable it is, and the fewer failures it will have!
3、Fool-like operation, minimal control.
The use of the sludge dewatering desktop is very simple, the labor price is enormously strong, and the labor pressure is decreased a lot. Just press the button gently, and the sludge pump dosing pump starts offevolved to work, and the gear starts offevolved to run or ends to run! It is too easy for different devices.
Slow speed, the low failure rate
Theoretically, the frequency of altering things to do as soon as a yr is no longer high! Some sludge desserts with low water content material and excessive long-term load want to be changed regularly
5. Low power consumption and energy saving
6、Low investment cost, simple parts requirements
Main peripheral equipment
(1) Sludge pump: transport the sludge to be dealt with to the sludge inlet of the sludge thickener.
(2) Dosing pump: dosing the organized polymer answer to the sludge conditioning tank or pipeline static mixer.
(3) Pam dosing system: the polymer of the powder is organized into 0.1%~0.3% flocculant lotion. Manual dosing, mechanical mixing or automated quantitative dosing and training device shall be adopted, and the guidance and maturing time shall be 30 minutes or more.
