Sludge Drying Solution for Optimal Recovery
Sludge is a
semi-solid product left from industrial or refining processes. A separated
solid suspended in a liquid, containing major quantities of interstitial water
between its solid particles. Sludge drying is the process of transforming sludge into useful products. Removal of water decreases storage
volume and transportation costs.
Drying
the sludge makes suitable for recovery:
Stabilised sludge
Reducing
olfactory nuisances and improving sanitization
Reduced weight and volume
Eliminating the
water from the sludge reduces its volume and weight, making for easier storage.
Easier sludge removal
Enables
minimum dry content levels to be reached that are legally required for use in
cement works ovens
Easier revival
By
evaporating the water, the end product can be prepared for use in a composting
facility
Evaporating the water in the sludge by different drying
processes
Depending on
the level of dry content, the sludge has a specific behaviour that influences
the thermal drying processes. There are three ways of transmitting heat are
conduction, convection and radiation. Technoforce Solutions PVT LTD proposes three sludge drying processes:
1.
Thermal Sludge Drying in Low Temperature
Ranges
Our
High-Tech dewatering and low temperature sludge dryers with advanced
dehumidification heat pump technology have the ability to process stabilized sludge
at 1% solids and dry to 90% solids, in one slow moving energy efficient
process. This is automated drying process uses the principal of continuous
drying by the convection of hot air.
2.
Mixed Sludge Drying combines thin
film dryer and hot air belt dryer
This sludge
drying process recovers the thermal energy.
This treatment can be a three step process:
a.
Indirect
drying by thin film evaporator
b.
Mechanical
extrusion
c.
Direct
drying by belt dryer
3.
Solar Drying
In this
process, clean and renewable energy sources to dry sludge. It uses the same
principle as horticultural greenhouses, completed by a ventilation system. Solar sludge dryers require the sludge
to be dewatered before entering the dryer. Using these current solar
drying systems, the sludge then needs to be turned with a robotic vehicle
mechanism that aerates and mixes the sludge inside the drying chamber.
The limits
of sludge drying sometimes create the need for thermal drying by water
evaporation. Technoforce Solutions PVT
Ltd has developed a number of sludge
drying processes that allow the sludge to be recovered for a multitude of
uses as fertilisers, co-products for composting or as fuel for incineration
plants. Our products are family oriented driven to produce high-quality
wastewater treatment equipment made in India. We believe to make a positive
impact on the planet by keeping our finite water
supply clean and usable for generations to come.
Technoforce Solutions PVT Ltd as a manufacturer of sludge dryer, designs a
small, medium and large quantity sludge generators. These sludge dryers can fit
under the filter press for direct loading or can be located elsewhere in the
plant. The dryer is designed for continuous drying of pasty materials. Our
experienced engineering staff is constantly striving to build and improve upon
wastewater machinery. Our flexibility allows us to deliver our parts and
products in a timely manner.
