As environmental regulations for Bio-Solids become more restrictive, sludge handling & processing become more critical. Kappe Associates, Inc. offers a variety of the most advanced and comprehensive product lines for sludge management. widely applied to automobile painting sludge, desulfurized sludge, chemical sludge, desulfurizing and denitration sludge from large and medium sized enterprises. Meanwhile, this solution can be also be utilized to viscous and high moisture materials. If you are interested in our heat pump dryer, please contact us for more information, such as catalogue, video,etc.
All the rotary plates are connected to the hollow shaft by welding. Spiral heat exchangers can also be used for final effluent cooling to recover heat and, if it is to be discharged into the sea, river or stream, to protect the biology of the water body. Biological sludge is dominated by microorganisms and includes solid particles such as sediment, fiber, animal and plant residues, as well as organic matter, metal, germs, eggs and other substances that may be adsorbed. Their specific surface area and porosity are very high (porosity is often more than 99%).
VAPORUN has made a series of optimization and improvement of sludge drying system, thus becoming the most professional sludge drying equipment manufacturer in China. According to statistics, about 80% of the sewage plants have sludge concentration and dehydration facilities, which has reached a certain degree of sludge reduction. Most of the sludge in landfills, open-air stacking and transportation belongs to random disposal, and the proportion of real safe disposal is not more than 20%. Simple treatment of land encroachment is serious, and it is not easy to find a suitable site. At the same time, if the seepage prevention technology is not enough, it will lead to potential soil and groundwater pollution. For a long time, for the overall environment, it is equivalent to the lack of effective treatment of sewage.
The Spring Sales is a purchasing festival from March 1 to 31, 2021. During this period, products that have special offers and support extra services can be found on Made-in-China.com. Equipment developed by our company is characterized by long service span and high production efficiency. The process is based on a compact technology which can be used also in a series of joint modules. Compact design, no operative costs for filters and the lowest energy consumption make Drywa 100% green and eco-friendly. DryWa technology is developed to make sludge management efficient and cost-effective, respecting the environment and climate.
It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles. This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge. Belt presses are an effective and efficient way to clean all types of process water, waste water, industrial and agricultural water, and more. Once the solids are separated out using the belts and rollers, they are typically augered into a container or truck for easy disposal. Contact us today to learn more about our belt press sales, belt press rentals, dewatering, water clean-up projects, and more.

The particles are instantly entrained and conveyed in the sweep gas and exit the jacket in a matter of seconds during which time the sludge granules are dried and the temperature of the conveying gas is dramatically reduced. The pneumatic conveying and drying process continues during the relatively short transport time to the cyclone where the product particles are separated and discharged via a rotary valve to the stockpile. 4.All the materials in the drying room are heated evenly.The product after drying has uniform color and luster.The quality of dried products is superior to natural drying. 4).The slag quantity and water content can be adjusted and can be used to different composition feed. The solid matter is very suitable for fish feed and the raw materials of the organic fertilize. 5).The working efficiency of the solid liquid separator machine is related with raw manure storage time, dry substance content, waste water viscosity such factors.
Such a cover protects the bed from precipitation but provides little temperature control. Because of better temperature control, completely covered beds, require about 25 to 30% less area than open beds. Sludge, produced from the treatment of wastewater, basically consists of two basic forms- raw primary sludge and secondary sludge. Below are the methods described that are most commonly used to process the sludge produced during wastewater treatment. Griffin Residuals provides Own/Operate drying facilities using the most advanced drying technology in the market .
Use Nissei or Nord brand reducers, industrial quality from Japan and Germany. Börger Rotary Lobe Pumps are self-priming , valveless, positive displacement pumps. Against new national call to develop sustainable economic mode, painting sludge gradually becomes a main problem paid attention by different customers.
We preferably use additional waste heat or wastewater heat from renewable sources to speed-up the drying process. This type of dryer is particularly suited for small to medium-sized wastewater treatment plants. They are sludge harmlessness technology, sludge recycling technology and sludge quantity reduction technology. Aimed at customers’ application scenarios and materials’ properties, we have developed multi-series equipment. After years’ practice and experience accumulation, our drying systems can use electricity, microwave, exhaust gas, oil, fuel gas, coal and wood as fuel to provide heat. Our drying equipment can be used to directly deal with sludge with various state after mechanical dewatering process and adapt to moisture content range from 25% to 90%.
The entire process including the material feed, the mixing, drying and subsequent pelletization is monitored by a Siemens S SPC control unit. All sensor data, temperatures, flow rate volumes, pressures, speeds, run times, etc. are continually recorded. An active support unit scans the data and if deviations to the target value tolerance are noticed, then the intended requirements are carried out. The entire process is visualized by a touchscreen panel on the HMI. Important functions, like the opening and closing of the chamber valves and the filter cleaning, require compressed air.
If the compressed air supply is interrupted or the required minimum pressure is not present, the pressure sensor recognizes this and the SPS initiates the necessary measures. If this occurs during operation, the energy supply is immediately interrupted and the dryer is switched off. The sludge is very sticky and has a special sticky phase during the drying process (40%-60% moisture content). In this extremely narrow transition section, the sludge is easy to agglomerate, the surface is hard and difficult to crush, but the inside is still thin.
