The new sludge dehydrating agent (sludge enhancer) has shown remarkable effect in solving the problem of sludge press filtration. The following is a detailed analysis of how the new sludge dewatering agent can effectively deal with the problem of unformed sludge press filtration
First, the characteristics of new sludge dehydrating agent
Pure organic ingredients: The new sludge dehydrating agent is a pure organic sludge dehydrating agent, which does not contain chloride ions and calcium ions, and is specially designed for the problem of unformed sludge press filtration.
Polymer modification: By changing the physical and chemical properties of sludge, improve the sludge filtration dewatering effect.
Mechanism of action: Through synergistic action, the surface properties of sludge are changed, the specific surface area of sludge is reduced, the cell wall and cell membrane are destroyed and the intracellular water is released, and then the free water, bound water, capillary water and intracellular water in most biochemical sludge are removed.
Second, the application of new sludge dehydrating agent in solving the problem of sludge press filtration
Surface structure changes: After the use of new sludge dehydrating agent, the surface structure of the sludge becomes smooth and flaky, the pores and gaps of the original sludge are significantly reduced, the surface of the sludge is smooth, the specific resistance of the sludge is small, and the water filtration performance of the sludge is increased.
Application Case:
The municipal sludge in a municipal sewage treatment plant has high organic matter, and the traditional sludge conditioning method is not effective.
After adding the new sludge dewatering agent, the floc in the sludge becomes more compact, the specific resistance of the sludge is reduced, the feed speed of the plate and frame filter press is accelerated, the filter press time is shortened, the water content of the mud cake is significantly reduced, and the non-stick filter cloth is formed, and the expected effect is achieved.
The amount of sludge has been reduced, and the disposal cost of sludge has been greatly reduced.
Third, the use of new sludge dehydrating agent precautions
Agent selection: The nature of the sludge is affected by the source of sewage, sewage treatment chemicals and other factors, so it is necessary to select the agent selection according to the specific situation, and select the appropriate model of new sludge dehydrating agent.
Dosage control: too much or too little dosage of new sludge dehydrating agent will have an important impact on the dehydration effect, so it is necessary to determine the accurate dosage through small and pilot tests before formal use.
Use with plate and frame filter press: The new sludge dehydrating agent is a conditioner specially designed for use with plate and frame filter press, and it is necessary to ensure a good fit between equipment.
In summary, the new sludge dehydrating agent (sludge enhancer) has significant advantages in solving the problem of sludge press filtration failure through its unique composition and mechanism of action. Efficient and economical sludge dewatering treatment can be achieved through reasonable selection of agents, dosage control and equipment coordination.
