Transcend Cleantec Private Limited has pioneered the technique of manufacturing Multi Disc Screw Press in India. These sludge dewatering press are intended for mechanical dewatering of community and industrial wastewater sludge. They are recommended for wastewater sludge dewatering on low-capacity municipal wastewater facilities, as well as for food, pulp-and-paper, pharma,textile, chemical, oil-refining and similar industries. These sludge dewatering press are efficiently used for dewatering rates of up to 1000 kg/hr – dry solid mass. These dehydrators are a good alternative to traditional dewatering equipment. It provides dewatered sludge with a moisture content of less than 80% in conditions of classic wastewater treatment plants.Enquiry Now
The conventional sludge dewatering systems like centrifuges, Belt press, Filter press (Plate & Frame type) have many draw backs. The drawbacks include-
- Large foot print
- High power consumption
- High Operational cost / consumables
- Frequent breakdown
- Non-continuous (batch) operation
- High maintenance requirement
- Multiple Pretreatment
- High labor
As the Multi-Disc Screw Press can take the load directly from the oxidation ditch, considerable capital cost, construction costs and maintenance cost can be avoided
DIRECT DEWATERING FROM OXIDATION DITCH
Feed sludge directly from the oxidation ditch / aeration tank. This eliminates the need to construct settling tanks, sludge thickener or sludge feed tanks. This advantage leads to a good reduction in CAPEX as well as OPEX.
CLOG FREE DESIGN
The series of heavy duty finely machined fixed and rotating rings placed alternately provides efficient filtration that remains clog free due to the continuous movement of the rings. This eliminates the need for consumables like filter cloth etc
The system can be fully automatic with PLC controls. Option of variable frequency drive (VFD) is available to control the dosing and the screw speed to automatically adjust to the varying loads of the effluent. The system can run continously, unmanned.
The system can take sludge directly. This eliminates the need to build sludge thickening tank and sludge storage tank, thereby saving on space and civil construction costs.
Since both the sludge thickening tank and the sludge storage tank is eliminated and as sludge is not stored for long periods of time, there is no anaerobic process happening. This eliminates the possibility of unpleasant odour.
HANDLES OILY SLUDGE
Due to the rotation of the helical axis, the moving rings detach from the fixed rings while continuous- ly cleaning itself. As a result clogging is avoided. Therefore it can easily handle oily sludge.
The system works on its internal pressure. It saves energy due to its low running speeds (2-4 rpm). The average power consumption is only 0.01 – 0.1 kw/h which is 12% of a belt press and 5% of a centrifuge
The Transcend Cleantec Screw Press takes the least space among other technologies. Its approximately 45% less space than Centrifuge, 62% less space than Belt Press and 78% less space than Filter Press of conventional design.
CAPACITY & SCALABILITY
Transcend Cleantec Multi Disc Screw Press is designed to cater to various capacities. Systems are available from 0.2 m3/hr – 133.5 m3/hr (@0.2%sludge conc.) Due to its modular design and compact construction, the capacities can be easily scaled up by running systems in parallel to cater to almost any capacity as required and as and when required. We can also optimize the design for cost and efficiency based on your custom requirement using the standard models.
INSTALLATION, SERVICE SUPPORT & TRAINING
Our experienced and trained team of engineers help you with the installation and operator training. Our systems are designed to be a work horse and run for years without needing any service. But there are odd chances that you may need service support. Our trained technicians are an email or call away. With adequate training and spares at their disposal, they will ensure the system is up and running in a very short time.
