Product Description

 

Screw press dehydrator is used for the thickening and subsequent dewatering of sludge. The equipment is small and lightweight and can work in automatic operation with minimal maintenance requirements. The device guarantees the thickening of activated sludge to at least 18% of dry matter, for sludge from municipal WWTPs.

Screw press dehydrator is produced in several lines, and thanks to its low investment as well as operating costs, it is suitable mainly for industrial treatment plants and municipal treatment plants from 1,000 to 10,000 PE. Another great benefit of this device is the ability to thicken secondary sludge directly from the activation, which may eliminate the cost of the construction of storage tanks within the design of a new WWTP

INTRODUCTION

1. Concentration: When the spiral push shaft rotates, the multiple solid and active laminations located on the periphery of the push shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving laminations, achieving rapid concentration.

2. Dehydration: The concentrated sludge continues to move forward with the rotation of the spiral shaft; along the direction of the mud cake outlet, the pitch of the spiral shaft gradually becomes smaller, the gap between the rings also gradually becomes smaller, and the volume of the spiral cavity becomes smaller. Continuously shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Driven by the continuous operation of the spiral push shaft, the water in the sludge is extruded and discharged. The solid content of the filter cake continues to increase, and finally the sludge is realized. of continuous dehydration.

3. Self-cleaning: The rotation of the spiral shaft drives the moving ring to continuously rotate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common clogging problem of traditional dehydrators.




ADVANTAGES

It can directly process the sludge in the aeration tank or the sludge in the secondary sedimentation tank. There is no need to set up a sludge concentration tank and storage tank, saving space.

Improve the phosphorus removal function of the system: The sludge is dehydrated under aerobic conditions, avoiding the release of sludge phosphorus under anoxic or anaerobic conditions, and improving the dephosphorus function of the system.

Simple operation and management: There are no filter cloths, filter holes and other easily clogged components, making the operation safe and simple. Combined with the fully automatic dosing system, it can achieve 24-hour unattended operation.

Reduce system processing load: integrated sewage and sludge treatment to reduce the burden on subsequent biochemical reactors.

APPLICATION FIELDS

1. Suitable for sludge in municipal sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceutical and other industries.

2. Suitable for dehydration of high and low concentration sludge. When dehydrating low-concentration (2000mg/L~) sludge, there is no need to build a concentration tank or a storage tank, which reduces construction costs, reduces the release of phosphorus and the generation of anaerobic ozone.
