Sludge dehydrant as a new choice for environmental protection, can indeed reduce the moisture content of mud cake to less than 60%, the following is a detailed analysis of it:
Advantages of sludge dehydrating agent
Efficient dewatering: sludge dewatering agent can significantly change the surface structure of the sludge, reduce the solid surface load and specific surface area of the sludge, destroy the bacterial structure, and thus enhance the dewatering performance of the sludge. Combined with the plate and frame filter press and other equipment, the water content of the sludge can be reduced from more than 90% to 40% to 60%, and the significant reduction of the sludge can be achieved.
Environmentally friendly: Compared with the traditional lime dewatering method, the sludge dewatering agent can reduce the water content at the same time, but also reduce the environmental pollution. The use of lime not only has a higher moisture content, but also increases the difficulty and cost of dehydration, and also has a certain risk of environmental pollution. The sludge dehydrating agent is more environmentally friendly and conducive to sustainable development.
Low cost: The use of sludge dehydrating agent can reduce the operating costs of enterprises. Although a certain amount of money may need to be invested in the initial purchase of equipment and chemicals, in the long run, subsequent treatment costs and transportation costs can be significantly reduced due to improved dehydration efficiency and reduced water content.
Widely applicable: sludge dewatering agent is widely used in life, printing and dyeing, paper making, electroplating, chemical industry, leather and other industries of sludge dewatering treatment, with high versatility and practicality.
Two, the main components of sludge dehydrating agent
The main components of sludge dehydrating agent include inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent and sludge stripping agent. These components work together to make the sludge dehydrating agent play an efficient dewatering performance.
Application method of sludge dehydrating agent
In practical applications, sludge dewatering agents are usually used in combination with equipment such as plate and frame filter presses. Specific steps include:
The sludge was sent to the conditioning tank, and the sludge deep dehydrating agent and synergist were added into the conditioning tank.
Let the reagent and sludge fully mix and react in the conditioning tank.
The sludge is pumped into the plate and frame filter press through the automatic high pressure pump for dewatering.
The filtrate is returned to the sewage system for treatment, reused or discharged after reaching the standard, and the dehydrated dry mud falls into the conveyor belt below and is centrally sent to the discharge yard.
Four, precautions
When using sludge dehydrating agent, the appropriate type and dosage of agent should be selected according to the nature of sludge and treatment requirements.
The dewatering equipment should be regularly maintained and maintained to ensure that it is in good working condition.
Train the operators to improve the operation skills and level to ensure the stability and efficiency of the dehydration process.
In summary, as a new choice for environmental protection, sludge dehydrating agent has the advantages of high efficiency dehydration, environmental friendliness, low cost and wide application. It has broad application prospect and popularization value in sludge treatment industry.
