11--22 SSttrruuccttuurree ooff tthhee SSyysstteemm Volute Dewatering Press has been developed mainly for the purpose of dewatering the organic sludge.
Volute Dewatering Press is the combination of the following devices;
・・・・・・・・・・・・・・・・ Heart of the system. Thickening and dewatering of sludge. ■Volute Cyl inder ■Flow Control Tank ・・・・・・・・・・・・・・・・ A necessary amount of sludge is measured by V weir. ■Flocculation Tank ・・・・・・・・・・・・・・・・ The sludge is made to react with chemical in this tank. ■C o n t r o l P a n e l ・・・・・・・・・・・・・・・・ Control Panel includes features of Manual/Auto operation.

11--33 PPaarrttss OOuuttlliinnee ① Volute Cylinder ①-1 Structure The moving rings and fixed rings are arranged in layers one after the other and the
screw pitch narrows from thickening zone towards the dewatering zone.
Figure-2 Volute Cylinder Structure
①-2 Dewatering Principle The former part of Volute plays thickening role and the latter part plays dewatering role. In the thickening zone, the rings are made of resin. Filtration part separates sludge from filtrate water as it is like a bar screen. In the dewatering zone, the rings are made of stainless steel. The screw pitch narrows from thickening zone towards the dewatering zone, thus making the pressure in the dewatering drum to increase. The End Plate (Figure-2, E) increases the inner pressure even more, thereby dewatering sludge and discharging the cake with solid content of approx. 20%.
Figure-3 Volute Cross Section ①-3 Self-Cleaning Structure
The screw passes through the filtration part and continuously pushes the moving rings up and down with its edge in accordance with its rotation. This causes the moving rings to move continuously, thereby cleaning the gaps in the filtration part to prevent clogging.

② Flow Control Tank Sludge from a storage tank is regulated to adjust feed sludge volume supplied to the flow control tank by the sludge feed pump, and constant amount exceeds V weir and it flows into the focculation tank. The sludge of the remainder returns from the water level adjustment pipe back to the storage tank.
Figure-4 Flocculation Tank
③ Flocculation Tank In the Flocculation Tank admixing of the chemical substance is carried out in order to form flock. The flock is then transferred to the Volute drum where instantaneous gravity thickening takes place at the same time and then the flock moves through the thickening zone.
④ Control Panel Control Panel has the function not only for manual operation but also for fully automatic unattended operation with 24 hours timer for the attached facilities. Water level control is possible as well by means of receiving operation signal from a sludge storage tank. *Circuit of sludge pump and chemical feed pump is included in the Control Panel.

22.. DDeessiiggnn CCrriitteerriiaa The following Design Criteria should be met when you install Volute Dewatering Press in your WWTP facility design.
22--11 SSuuiittaabbllee SSlluuddggee ffoorr VVoolluuttee PPrroocceessss 1) Organic Sludge. 2) Feed sludge concentration should be about 0.2 ~ 3 %.
【Explanation】 1)100% Inorganic Sludge is difficult to dewater due to structural matter of Volute Screw.
In case of high ratio of inorganic sludge among organic sludge is difficult to show good performance as usual. In such case, please ask us for our free beaker test just before your design work and procurement.
2) Under the condition of sludge concentration is below 0.2%, process speed tends to decrease a little and then performance tends to show a worse performance. In case when sludge concentration is over 3.0%, there is possibility that it could not show standard performance as well. High concentrated sludge prevents enough agitation in Flocculation Tank and then enough reaction between sludge and chemical.
22--22 CCoonnddiittiioonnss ooff PPrree--PPrroocceessss ooff SSlluuddggee 1) Always agitate sludge to keep steady solid concentration. 2) pH of the sludge should be in the range of 6 ~ 8. 3) Screen would be required in case when rubbish, dead leaves, fur, straw and fiber
are included in sludge. 【Explanation】
1) and 2) In case of big range of concentration, it is difficult for the system to get steady performance because frequent adjustment for quantity of chemicals is required.
22--33 PPeerrffoorrmmaannccee
1) Standard Throughput 100 φ × 1 pc ~ 3 kg-DS/h (surplus sludge) ~ 5 kg-DS/h (floating floth) 200 φ × 1 pc ~ 9 kg-DS/h (surplus sludge) ~ 15 kg-DS/h (floating floth) 2) Water content of sludge cake is below 85% in case of dewatering surplus sludge
from biological treatment. 3) Chemicals for the right performance can be selected from Polyferric Sulfate and Polymer
Coagulant depending on sludge property.
(9/19)
【Explanation】 1) Throughput is influenced by sludge property (quality and concentration).
Table-2 Standard Performance (per one cylinder).
Quality Concentration D Easy Dewatering Difficult Dewatering
φ100 3 kg-DS/h 4kg-DS/h 0.6 ~ 1.0 % φ200 9 kg-DS/h 12kg-DS/h φ100 4 kg-DS/h 5kg-DS/h
1.0 ~ 3.0 % φ200 12 kg-DS/h 15kg-DS/h
2) The use of standard polymer coagulant such as Anion and Cation easily achieves 85%
or lower water content of sludge cake. When water content of sludge cake is the highest priority of a client, it is possible to achieve a better performance by selecting a more suitable polymer coagulant.
3) In case of flocculated sludge, add Anion 2.5 ~ 3.0%(liquid conversion against DS) and Cation 2.5 ~ 3.0% (liquid conversion against DS). In case of activated sludge, add Polyferric Sulfate 15% and in Amphibious 2.5 ~ 3.0% (liquid conversion).
22--44 CCoonnttrrooll PPaanneell 1) The speed of Volute motor and Flocculation Tank Agitator is controlled by the
inverter inside the Control Panel. 2) Switch and Indications in Control Panel are for common use up to screw number 1pc ~
5pc. 3) Circuit for a sludge feed pump, a chemical feed pump (Anion, Cation and Polyferric
Sulfate) are pre-installed. 4) 24hr Timer is pre-installed. 5) “Receiver for stop signal from outside” is pre-installed. 6) Dispatch by “Dehydrator collective trouble”
*Motor capacity of each item is referred to the attached Skeleton. 【Explanation】 1) Volute motor speed is controlled by the inverter to adjust a process speed easily. In
case when Volute Screw are more than 2 pieces, thermal switch are equipped at the secondary inverter.
Flocculation Tank Agitator is controlled with the inverter for correct reaction of sludge and polymer.

Note: _The life span in the Table-9 is only for your reference, calculated based on the operating conditions of treating excess sludge from biological treatment, producing 15% DS cake, at 8 hours per day. This data is acquired through a research on wearing of Moving Rings and Volute Screw, recorded in the Technical Document.
The life span varies depending on types of feed sludge and quality, especially on inorganic sludge. Moreover, producing sludge cake with solid content higher than approximately 17% may result in a shorter life span.
_Depending on wearing conditions, Moving Rings at thickening zone may have to be exchanged. _As long as Volute continues to operate normally, being confirmed by sludge cake produced and leakage on the Cylinder, the consumable parts do not have to be replaced even after the listed life span.
