Aldebaran plant has a compact shape but is able to clarify large quantities of water as a complete traditional system, with the advantage of taking up less space and being self-supporting, easily transportable and ready for use.
VERSATILE AND MODULAR
Aldebaran Compact is very versatile and modular as it can vary the wastewater treatment capacity replacing the clarification tower. In this way the system can increase the operating capacity up to 800 liters.
THE IDEAL CHOICE
Its complete and efficient structure and its ease of handling make it particularly ideal for use in the presence of rough environmental conditions (too high or too low temperatures) both indoors and outdoors, or in construction sites and quarries.
Aldebaran is a complete and innovative plant “package” type for the high efficiency clarification of waste water and for the dehydration of industrial sludge from natural stone or aggregates processing or other processes. The plant consists of a bearing structure made in high quality welded steel and protected by hot galvanizing treatment. Tesimag has studied a special sludge filtration system that guarantees better efficiency in clarification of waste water. The compact shape and the absence of protruding equipment, together with the reduced overall dimensions, determine an excellent balancing of lifting that simplify the movement. The limited weight and the particular geometrical shape allow the transport and the movement of the system assembled and ready for use, using traditional means like forklifts or cranes, inside work areas. Contrary to traditional plants with silo clarifier, Aldebaran plant does not require any kind of foundation.
Aldebaran plant is ideal for all companies that do not have wide space available, or that, for rough environmental conditions (temperatures too high or too low), must opt for installation inside the factory. It is also ideal for all companies operating in construction sites and quarries, because the plant can be easily moved to different areas of operation.
This innovative plant, completely autonomous, is equipped with all the elements necessary for the operation, from the waste water pit pump to the clarified water boosting pump. The dehydration of sludge resulting from the clarification process is performed by a filtering big bag (mod. Aldebaran Bag) or by a filter-Press (mod. Aldebaran F30).
Aldebaran plant has been designed for a close cycle working as follows:
Process waste water is convoyed into a collecting tank and pumped to the special silo. In this silo the mudfalls down thanks to the lamellar pack system, it is extracted by means an horizontal centrifugal pump and pumped to a filter press or to a filtering big bag. The water resulting from mud dehydration is pumped to waste water collecting tank in order to restart the sedimentation cycle. The clarified water flows to the top of the silo and then into the clear water collecting tank where it is pumped to the machines.
In order to accelerate the sedimentation of the mud, it can be used a flocculant solution prepared into the specific tank by a mixer and automatically injected in the waste water pipe by means of a dosing pump.
SEDIMENTATION WITH LAMELLAR PACKS
The sedimentation tanks with lamellar packs represent a complete system of sedimentation of the solid parts suspended in the water. The surface of the sedimentation tanks is formed by a lamellar pack (4)made of oblique and parallel lamellas.
The water to be treated is injected into the tank by a vertical centrifugal pump through the central inlet (1) and flows through the filtering active mud layer (2) where starts the separation of the mud particles. The flow rises inside the lamellar pack (3). Inside the channels of the pack the speed of the rising water is constant and therefore the mud flakes, because has a higher density than the water, settles (5) in the bottom of the channel and then slides in counter current flow in the bottom of the clarifier (9). The mud is extracted by an horizontal centrifugal pump (10), homogenized (11) and pumped to the filterpress (12). Meanwhile the clarified water overflows down into the collecting channels (7) and comes out from the clarifier through the exit flange (8). Back Flow is a special automatic function of Tesimag lamellar treatment plant that allows to keep activated the filtering layer: the mud is extracted and pumped back into the clarifier. This function also has the advantage of avoiding the clogging of the discharge pipes and the compacting of the mud. The dimensions on Sirion plants, compared with the traditional sedimentation tanks, are lower by 90%. This means that a surface of a square meter on the ground is in proportion to 10 meters of a traditional sedimentation tank. This plants can be equipped with a big bag filtering system or a filterpress for mud dehydration.
