Sludge dewatering is the process of separation of components of solid and liquid sludge to minimize the sludge disposal. There are many techniques available for Sludge dewatering which includes drying beds Filter press, Belt press, decanter, centrifuge & latest & advanced being Sludge dewatering press. Sludge dewatering equipment is not intended to treat the sludge or liquid but; it only separates the liquid components & solid components so it will get easier & cost-effective to handle the separate phases of the disposal. Once the final sludge has been dewatered, then the liquid is treated in ETP/STP & solid sludge is disposed.
The main purpose of the Sludge dewatering machine is to minimize handling and disposal. Sludge dewatering press is the most cost-effective method of dewatering and hence helps to sustain the environmental objectives of the company. Basically, both the public & private sectors are required to dispose the sludge which is approved by industries. Sludge dewatering is totally focused on the reducing weight as well as volume of sludge & also on cost & transportation services. First step of Sludge dewatering is removing water from it so by removing water it will impact on reducing volume & weight of sludge.
The MBBR media system is appraising a biofilm process. Other conventional biofilm processes for wastewater treatment is also known as trickling filter, rotating biological contactor (RBC) and biological aerated filter (BAF). TRANSCHIP MUTAG MEDIAprocedure in commonneeds less space than activated sludge structures because the biomass is more focused, and the efficiency of the system is less dependent on the final sludge partition. A disadvantage with other biofilm processes is that they experience bio clogging and a build-up Microbial loss.
Enquiry NowSludge dewatering press is treatment which generates dewatered cake with high dry solid content and a quality of cent rate water, leading to vital sludge volume reduction. So, that’s why the prices which are related to sludge dewatering screw press have been decreased. With its long industrial expertise, dewatering Industries is your resolution supplier and sludge screw press manufacturer for cost-efficient Sludge Dewatering, to manage a large vary kinds of sludge. That being a foresaid, the multiplate sludge dehydrator,unit is appropriate to handle each biological and physical-chemical kinds of sludge. Transcend Cleantec Pvt. Ltd. Is a one of best manufacturers of sludge dewatering Screw equipment, Transcend has been on the fore front and has been pioneer of such machines manufacturing in india.
Transcend has been market leader with succefully supplying and commissioning Sludge about 100 machine to varies industries Businesses and municipalities trust us, as a result of they know that our commitment & value driven manufacturing approach we have produced superior sludge dewatering screw press in India…MADE IN INDIA Transcend’s Multi-disc sludge press utilize both gravity filtration and screw compression techniques Transcend’s Multi-disc screw press dehydrators can cope up with a wide range of sludge concentrations from 0.2% to 10%, and also stably can dewater sludge that has high oil content.
Multidisc are arranged one after other with alternate disc being moving and fixed. The gap between the plates acts as media for fine filtration. The screw press main unit requires very very low power motor and the filtration surface area consists of a multiple discs which are self-cleaning, and generally do not clog, thus, the sludge press can be used continuously. The main unit of the sludge dewatering screw press is of multi-shaft design. Hence, when two or more main units are configured into one machine, any individual shaft can be repaired or serviced without interrupting operations.
Also the pitch of the screw flight is gradually increasing making the valley / volume available for the sludge narrow towards the outlet so that flocculated sludge that is concentrated by gravity filtration is further dewatered by compression.
| Simple : Low maintenance. |
| Low speed: No (or very low) live floor loads. Nothing special is required. |
| Reduced noise: Nothing special is required. Acoustic protection is not required. |
| Vibration and temperature: Monitoring is not required for the Screw Press. |
| Low Power Consumption :Low installed HP and reduced power consumption |
| Reduced installation costs for the electrical connection. |
| Simple and short start-up and shut down procedures. |
| Frequent stops and starts are possible. |
| In the event of an eventual shut down, repairs can be completed at the waste water treatment plant by regular mechanics. |
| For a multi-channel machine, one or more channel(s) may be removed for maintenance purposes, while the machine with the remaining channel(s) may still be operated. |
| Vibration analysis and preventative maintenance are not critical |
| The Screw Press includes a flocculator with a variable speed agitator to optimize flocculation and polymer dosage, which most likely results in a reduced polymer consumption. |
| More reliable:Very few components of the Screw Press reduce the possibility of catastrophic shut down of the equipment due to its low speed and simple design. |
| The effects of grit are greatly reduced in the slow-moving Screw Press. |
| No external lubrication system is required. |
| Low maintenance cost. |
| Simple :High maintenance. |
| High speed:High live floor loads. Building needs to be designed especially to deal with these loads. |
| High noise: Noise attenuation is required as part of the building construction. |
| Vibration and temperature: Monitoring of the electric motor, bowl and scroll is very critical. |
| High Power Consumption :High installed HP and high power consumption (around 20 times more than screw press). The additional power cost over the life of equipment is very significant. |
| High installation costs for the electrical connection. |
| More complex and lengthy start-up and shut down procedures. Bowl may continue to rotate for a while after shut down. |
| Frequent starts and stops are not possible. |
| In the event of a shut down, the centrifuge may have to be shipped to the manufacturing plant for specialized repairs. The centrifuge may require visits from specialty mechanics. |
| The whole machine is in operation or it is shut down. |
| Vibration analysis and preventative maintenance are very critical. Additional training of plant personnel may be required. |
| Flocculation takes place inside the centrifuge and cannot easily be controlled, and may result in a higher polymer consumption and higher annual expenditures. |
| Less reliable:Many more components may cause a shut down due to the high speed and high power. |
| The centrifuge may be affected by the presence of grit in the sludge in the form of unpredictable premature abrasion wear. |
| External lubrication system is usually required. |
| High maintenance cost. |
| Space requirements: Requires very less space |
| Operation: Runs 24×7 throughout the year. |
| Mobility: Can be moved to different locations, if required. |
| Capture Rate: A high capture rate is fundamental property of the Screw Press and frequent adjustment is not required to maintain it high. |
| Working: Can work continuously automatically. |
| Maintenance: Maintenance is easy |
| Sludge Cake: Obtaining sludge cake is easy and automatic |
| Flocculator is inbuilt in the Screw press |
| Space requirements: Requires very large space |
| Operation: Unreliable in rainy and cloudy seasons. |
| Mobility: Once constructed, cannot be moved. Needs to be demolished and reconstructed. |
| Capture Rate: The capture rate is very less. |
| Capture rate depends upon the bed media. However there are high chances that the sludge passes through the media without the solids being captured and the filtrate may contain huge amount of solids. |
| Working: Can work only up to the holding capacity of the beds. |
| Works in batches. |
| Maintenance: Maintenance is cumbersome. |
| Sludge Cake: Sludge cake has to be removed manually and is cumbersome. |
| Flocculator needs tp be procured separately adding to the overall cost. |
