Sludge Handling & Processing

By | July 15, 2021

This is an essential stage because, quite often during the handling processes, the sludge’s granular structure can be damaged, at least in part. Furthermore, this unit must be protected by stringent safety rules . The central shaft of the rotor is the bearing part of the dry rotary plate, with a hollow structure.

The filter main part is formed by a screw axis with fixing and moving plates overlapping. It dewaters adequately by the gravity and the power from back pressure plate during the process. The filtrate water comes out from the space between fixing and moving plates. For the Disc Type Sludge Dryerdeveloped by VAPORUN, the material is fed into the dryer from the feeding port, and the working medium flows between the shell and the hollow shaft. Through the jacket, hollow shaft and hollow disc welded on the shaft to transfer heat, the material is indirectly heated and dried, resulting in the accumulation of water vapor in the dome on the top of dryer.

If customer needs other requirement, we can carry out further dehydration. This process is called sludge drying process which is always finished by sludge drying machine. After drying process, sludge moisture will be reduced to lower than 10%.

It also may be spread on agricultural land in order to make use of its value as a soil conditioner and fertilizer. Since sludge may contain toxic industrial chemicals, it is not spread on land where crops are grown for human consumption. Dewatering systems usually dewater sludge to % water and it is still very heavy. This means transferring that weight in sludge and water to the landfill. These units will dewater 40-10% water, thereby delivering a useful bio-solid as a green by-product.

Many design variations are possible, including the layout of drainage piping, the thickness and type of gravel and sand layers, and construction materials. BENENV has more than 2 decades of experience in wastewater and sludge treatment. In the discharge area, the drum is not set in this area, and the material can roll to the discharge port in this area to complete the drying process. In the guide area, the wet sludge enters the zone and the hot wind contact with the hot air rapidly evaporates. The materials are copied by the large guide Angle, which is not bonded to be imported into the next workspace. Dried or treated sludge offers a wide range of applications, mainly including agricultural land application.

No matter how sticky, adhesive and viscous the material is, Kenki can dry it without clogging inside of the dryer and with a stable, continuous operation. The special dual-screw constriction guarantees no operational trouble during the drying process. For some types of industrial waste, e.g. pharmaceutical, pasteurization of waste water sludge is a must.

Natural treatments, energy conservation, and carbon footprint reduction are some of the key considerations for communities facing energy and electricity challenges. Green technologies and the use of renewable energy sources, including solar and wind power, for wastewater treatment are evolving and will help minimize the environmental impacts of human activities. Ecological and economical natural wastewater treatment and disposal systems have already gained importance in many places, especially in smaller communities. These include constructed wetlands, lagoons, stabilization ponds, soil filters, drip irrigation, groundwater recharge, and other similar systems.

Electromagnetic speed adjustment system is used as transmission system, along with the automatic temperature controller. The product will maintain the original color, quality, taste and nutrient contents after being dried. KENKI Corporation has been established in January 1964 in Fukuoka, Japan, as a company specialised in developing, design and manufacturing of maintenance and industrial equipment.

The grain shape is not spherical and the individual particles are characterised by a rugged, coarse surface. Due to the way they are generated after the mechanical de-watering in the centrifugal stage, the particles possess a very large specific surface with bulk density ranging between approx. Heat is applied to dry the sludge, while the augers constantly toss and tumble the sludge for efficient drying. Typical payback on a Met-Chem Sludge Dryer varies from about 1-2 years depending upon the specific application and existing hauling costs. Sludge dryer reduces the sludge volume and weight by evaporation of water in it, making it easier to store and transport. New grouped self-cleaning device inside the inner wall makes it easier to dry various sludge and other materials of high viscosity.

In the one-stage sludge drying process, the sludge storage and drying is operated under closed negative pressure resulting in no odor. The drying process utilizes the advanced thin film sludge dryer, and recovers the heat of waste gas as well minimizes energy consumption and costs. In addition, the process is flexible, one-stage drying process can reduce moisture content to 30~45%. Four-effect condensation dehumidification drying technology is an advanced sludge drying reduction technology.
