The treatment of spent lees from distillery plant

Field of the invention

The present invention relates to a system for treatment of industrial liquid waste, more particularly, the present invention relates to a system for treatment of distillery liquid waste such as spent lees.

Background of the invention

Molasses, which is a by product of sugar factory is the main raw material for production of alcohol. The molasses is fermented to produce alcohol. During this process of fermentation, liquid waste such as spent lees is generated which creates lot of difficulties before the distilleries with respect to its storage and disposal.

Prior art

The conventional methods for the treatment of spent lees are:
• By mixing it in water reservoirs;
• By mixing it in spent lagoons; and
• By adjusting Ph by lime addition and to let it out.

Drawbacks of prior art

The above mentioned conventional methods are unable to provide a full proof zero discharge system for distillery liquid waste like spent lees.
Further, the above mentioned conventional methods are not capable of re-cycling the liquid waste back into the process so as to solve problem of industrial pollution.


Object of present invention

The main object of this invention is to provide a process and a system for treatment of distillery liquid waste such as spent lees, which is capable of re-cycling the liquid waste back into the process and thereby enabling the industry to solve the problem of pollution.

Another object of present invention is to provide a process and a system for treatment of distillery liquid waste such as spent lees, which is a zero discharge system for distillery liquid waste.

Further object of present invention is to provide a process and a system for treatment of distillery liquid waste such as spent lees, which is economical and can be used as per requirement.

Brief description of figure

Figure 1 shows flow process block diagram in accordance with the present invention of a system for treatment of distillery liquid waste such as spent lees.

Detail Description of the invention:

The foregoing objects of the invention are accomplished and the problems and shortcomings associated with the prior art techniques and approaches are overcome by the present invention as described below in the preferred embodiment.

The present invention describes a system for treating distillery liquid waste such as spent lees. The system is capable of recycling the liquid waste back into the process and thereby enabling the industry to solve the problem of pollution. Further, the system is a zero discharge system for distillery liquid waste. Moreover, the system is economical in construction and may be used as per requirement.

The present invention is illustrated with reference to the accompanying drawings, throughout which reference numbers indicate corresponding parts in the various figures. These reference numbers are shown in bracket in the following description.

Referring now to figure 1, a block diagram of a system (100) for treating distillery liquid waste such as spent lees in accordance with the present invention is illustrated. The system (100) includes a plurality of first chemical dosing tanks, the present invention is shown to include two three first chemical dosing tanks (1a, 1b, & 1c), a first reaction vessel (2), a first buffer tank (3), a first sand filter (4), a first carbon filter (5), a plurality of second chemical dosing tanks, the present invention is shown to include two second chemical dosing tanks (6a, 6b, & 6c), a second reaction vessel (7), a second buffer tank (8), a second sand filter (9) and a second carbon filter (10).

The first chemical dosing tanks (1a, 1b, & 1c) are for adding oxidising agents in the distillery liquid waste received from distillery plant. In the embodiment, the oxidising agent used is a mixture comprises of dichromates and peroxides. The mixture preferably consists of dichromates and peroxides of univalent cations. Preferably dichromates of Potassium and Sodium, and peroxide of Hydrogen are taken in the ratio ranging from 10 to 30:5 to 15:40 to 70. More specifically, the oxidising agents Potassium dichromate:Sodium dichromate:Hydrogen peroxide is added in the ratio of 15:10:60.

The distillery liquid waste dosed with oxidising agents are received in the first reaction vessel (2). The oxidised distillery liquid waste is allowed to react in the first reaction vessel (2) for time period ranging from three to four hours therein, thereby separating into sludge and liquid. the sludge is removed from a bottom (not shown) of the first reaction vessel (2). The liquid is sent to the first buffer tank (3).

Further, the first buffer tank (3) receives the liquid from the first reaction vessel (2). The liquid from the first buffer tank (3) is passed through the first sand filter (4) and then through the first carbon filter (5).

Referring gain to figure 1, the filtered liquid from the first carbon filter (5) is passed through the second chemical dosing tanks (6a, 6b, & 6c). The second chemical dosing tanks (6a, 6b, & 6c) for adding flocculating agents and neutralizing agents in the liquid received from the first carbon filter (5). The neutralising agent used is a mixture of two components. The mixture comprises of hydroxides of alkali and alkaline earth metals. In particular mixture comprises of hydroxide of Calcium and Potassium. The mixture components are taken in the ratio ranging from (35 to 60):(5 to 15). In particular the neutralising agent Calcium hydroxide:Potassium hydroxide is added in the ratio of 45:10. The two compounds are added in separate tanks. The pH of the liquid obtained after the dosing is between 6 to 8. Further, the flocculating agent used is sulphate of group 3 cations. In particular sulphate of aluminium and Iron (II) is used. The mixture components are taken in the ratio 25 to 60, 75 to 100. In particular the flocculating agents Potash Alum:Ammonium alum is added in the ratio 50:90. The addition is mainly for coagulation and flocculating, turbidity removal, and to flocculate other suspended impurities.

The liquid dosed with flocculating agents and neutralizing agents is received in the second reaction vessel (7). The flocculated and neutralised liquid is allowed to react in the second reaction vessel (7) for time period ranging from one three to four hours therein, thereby separating into sludge from the liquid. The sludge is removed from a bottom (not shown) of the second reaction vessel (7). The liquid is sent to the second buffer tank (8).

Further, the second buffer tank (8) receives the liquid from the second reaction vessel (7). The liquid from the second buffer tank (8) is passed through the second sand filter (9) and then through the second carbon filter (10), thereby obtaining water suitable for further use.

All the processes are carried out at ambient conditions of temperature and without use of any potentially hazardous reagents. Further, COD, BOD & TDS parameters of the treated liquid have shown great reduction (more than 80%). The liquid passing out of the carbon filter (10) is almost colourless as well as odourless.

Detailed descriptions of the preferred embodiment are provided herein; however, it is to be understood that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure, or matter.
