Sludge Screw Press Dewatering Machine for Paper Mill Wastewater

The sludge dewatering machine is very suitable for the treatment process of paper sludge treatment.

The working principle of the sludge dewatering machine in the paper mill:

When the screw drives the transmission shaft to rotate, multiple solid active laminates around the transmission shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving rings, achieving rapid concentration. The paper mill sludge moves forward as the screw rotates. Along the mud cake outlet direction, the screw pitch gradually decreases. The gap between the rings also gradually decreases, and the volume of the screw chamber continues to decrease. Under the action of the outlet back pressure plate, the internal pressure gradually increases. With the continuous operation of the screw drive shaft, the water in the sludge is squeezed out. The solid content of the filter cake increases continuously, achieving continuous dehydration of paper mill sludge.

自Cleaning: The rotation of the screw causes the drive ring to rotate continuously. The sludge dewatering machine achieves a continuous self-cleaning process by moving between a fixed ring and a moving ring. It avoids the blockage problem common in traditional equipment.

Advantages of using sludge dewatering screw press in paper mills (pulp mills):

Efficient dewatering: can effectively remove a large amount of water from papermaking wastewater.

Space saving: compact structure, does not take up too much space.

Automated operation: can reduce manpower input and improve work efficiency.

Stable operation: few failures, ensuring the continuity of production.

Wide range of applications: can handle various types of papermaking wastewater.

Good dehydration effect: the produced mud cake has a low moisture content, which is convenient for subsequent treatment.

Easy to maintain: maintenance and repair are relatively simple.

Apoaqua Pig Wastewater Dewatering Screw Press Machine for Sale

Apoaqua pig manure sludge dewatering screw press for sale.

In the livestock industry, manure wastewater is a vexing problem. Apoaqua's dewatering screw press is an advanced solid-liquid separation equipment, ideal for large livestock farms. The dewatering screw press has a simple working principle and unique advantages. Such as small footprint, simple operation, high degree of automation and low energy consumption.

Livestock wastewater contains a large amount of suspended solids and organic matter. The screw press can effectively reduce the pollutant concentration in wastewater during the sludge dewatering process. Dewatering screw press can adapt to the continuity of wastewater generation in livestock farms and ensure the stability of the treatment process.

The wastewater from farms also seriously pollutes the environment. Sewage and feces contain high concentrations of organic matter, high ammonia nitrogen and high suspended solids. It also contains a large amount of bacteria, ammonia nitrogen and organic phosphorus. Directly discharging sewage containing pollutants into the natural environment will cause damage to the ecological environment. All farms need to centrally treat and purify wastewater before discharging it. It can only be discharged into the natural environment if it meets the discharge standards.

For this purpose, we have specially designed a new type of pig manure sludge dewatering system.

Precautions In the process of manure screw press treating farm fecal sludge, PAM cationic agent is essential. The process of dissolving chemicals requires large amounts of water.

Usually the dissolved concentration of PAM cations is 1%-3%, and the dissolving agent is generally tap water from the farm.

For every ton of fecal sludge in the sludge thickening tank, about 0.3-0.5 tons of tap water is required. Probably about 1.5-2 times the amount of filtrate is produced.

For example, in a farm with a daily raw water treatment capacity of 60 tons, the manure screw press produces approximately 10 tons of filtrate water per day.

Function of Dewatering Screw Press

Generally used after anaerobic or aerobic biochemical treatment. Some are also used after flotation treatment and are suitable for sludge dewatering processes. It is an indispensable equipment in the dehydration room.

The advantage of dewatering screw press over traditional filter press is that it can be fully automated. Unattended operation for effective dehydration. Practice has proved that manure screw press can achieve objective economic benefits.

Save the amount of poly(acrylic acid) amine (PAM) cationic agent. According to experiments, using filtrate water for PAM cation dosing can reduce the dosage of the agent by about a quarter, thereby reducing the cost of the agent.

Use filtrate water to reduce tap water usage. Taking a treatment system with a capacity of treating 60 tons of aquaculture wastewater per day as an example, it can reduce the consumption of tap water by 5-8 tons per day.

Increase the treatment capacity of the aquaculture wastewater treatment system and reduce the use of tap water. This in turn increases the amount of aquaculture wastewater that the system can treat.

The filtrate water is recycled to avoid the impact of poly(acrylic acid) amine (PAM) cationic reagent on the subsequent system.

Hospital Sewage Screw Press Dewatering for Sale

With the continuous development of medical technology, the amount of sewage generated by hospitals is increasing. Screw press dewatering, as an efficient and environmentally friendly sludge dewatering equipment, has gradually been widely used in the field of hospital sewage treatment.

In practical applications, hospital wastewater treatment systems first remove large particles of impurities and suspended solids through a screen. Then it enters the regulating tank for water quality and water quantity adjustment. The water out of the regulating tank is pumped and then enters the screw press dewatering machine for treatment. The treated effluent can meet the discharge standards or reuse requirements, and the filter cake is cleaned regularly and disposed of safely.

Hospital wastewater mainly includes medical wastewater and domestic wastewater. Sludge dewatering equipment is used in the sludge dewatering process of sewage treatment. The amount of sludge in hospital wastewater is generally not large, so a small sludge dewatering machine is more appropriate. For example, Apo131 or Apo201 can fully meet the requirements.

Features of Dewatering Screw Press

Simple and compact structure: The dewatering screw press has a simple structure, occupies a small area, and is easy to install and maintain.

Strong processing capacity: The processing capacity is strong and can meet the needs of hospital sewage treatment.

Energy saving and environmental protection: It uses a motor with low power consumption and low noise. At the same time, its operation process is harmless to the environment.

Automatic control: The sludge dewatering screw press uses an automatic control system, which can realize remote control and monitoring and reduce manual intervention.

Strong adaptability: It has strong adaptability to water quality and flow. It can be widely used in various types of hospital sewage treatment.

As a highly efficient hospital sewage treatment equipment, multi disc screw press has broad application prospects. Through reasonable design and layout, the hospital sewage treatment effect and treatment capacity can be effectively improved. Provide strong support for hospitals to create a better medical environment. At the same time, with the continuous advancement of technology, Apoaqua brand sludge dewatering system will become more mature in the field of hospital sewage treatment.
