1.1.1 One (1) Pulp Mill Effluent Collection Sump with MCC & two (2) no. pumps to feed the raw effluent to the Flocculator & Tube Settler.
1.1.2 One (1) Flash Mixer with agitator, comprising turbine type impeller fixed to a vertical shaft resisting on guide supports and complete with reduction gear, flexible coupling, drive motor of required rating
19
and speed, common base frame etc. In Flash Mixer & Flocculator, Alum and Polymer solutions are dosed in order to carry out coagulation and pH adjustment respectively.
1.1.3 One (1) Buffer Tank to hold the flocculated effluent. Buffer Tank should have acid & alkali dosing provision for pH adjustment prior to feeding to the Anaerobic System/ Reactor for Anaerobic treatment. If Bio‐gas is generated in this system, it may be burnt in Gas Flare for obtaining heat energy.
1.1.4 One (1) Pre‐Aeration Tank for collecting the Anaerobic Reactor treated effluent to feed the Aeration Tank with surface aerators.
1.1.5 One (1) Micro Fiber Removal Unit or Dissolved Air Floatation Unit (DAF) for removal of grits & heavy solids and protection of downstream equipment for all PM No.5 area effluent. DAF should be provided with air blowers which will draw atmospheric air & facilitate Floatation.
1.1.6 One (1) Reactivator Clarifier with concrete center support structures with raw effluent feed inlets along with flocculating paddles, rake arm mechanism and blades to scrape the settled solids from the entire tank bottom towards the centre discharge cones. The reactivate clarifier is a high rate effluent treating clarifier, which produces treated effluent of highest quality with minimum time space & chemicals. The intimate contact between the effluent, coagulants & previously formed sludge causes the chemical reactions to proceed at a rapid rate with a minimum of treating chemicals. Furthermore by contacting water with the great volume of sludge in recirculation, maximum clarification of the water can be achieved by the adsorptive properties of the sludge or flocs formed. The clear overflow from Reactivator Clarifier gets collected in the Aeration Tank.

3.03.00 Technical Particulars:‐ 3.03.01 Pulp Mill Effluent Sump :
One (1) no. rectangular underground Effluent Sump (Length‐ 5 m, Width‐ 3 m, Depth‐ 2.5 m) made of RCC with MCC & two (2) no. pumps to feed the Pulp Mill Effluent to the Flocculator & Tube Settler via Flash Mixer. Effluent is pumped to the Flocculator via Two (2) [1 W + 1 S] horizontal centrifugal pumps, each of capacity 15 m3/hr and 10 m head.
3.03.02 Flocculator & Tube Settler: One (1) no. Flocculator & Tube Settler via Flash Mixer. The effluent from the Clextral pulp mill, which is highly contaminated with suspended solids and biological load has been taken in to a separate Effluent Sump, from there it will be pumped to Flash Mixer and Flocculator, where coagulant and polymer are dosed. Lime dosed in the flash mixer in which high‐speed agitator is provided for proper mixing of chemicals in water. Water from flash mixer enters in Flocculation chamber in which paddle type agitator is provided for gentle mixing. Polymer is added for flocculation of coagulated particles. Sufficient residence time is provided in this chamber for particles to become heavy before entering into Tube Settler.
3.03.03 Flash Mixer:
One(1) no. flash mixer of 2.3 m diameter with agitator, comprising turbine type impeller fixed to a vertical shaft resisting on guide supports and complete with reduction gear, flexible coupling, drive motor of required rating and speed, common base frame etc.
Materials of Construction:
Flash Mixer Tank : R.C.C
Agitator Impeller : M.S
Vertical Shaft : M.S
Valve : C.I frame & gate with
M.S. Spindle & Couplings
One (1) Tube Settler consisting of a series of inclined overlapping tubes, which are arranged to form a separate sedimentation chamber or the cells between each pair of adjacent tubes. The overlapping projected area of several tubes is a factor of increased surface settling area proportioned to the number of tubes/plates used. This configuration ensures laminar flow conditions, which results in hydraulic uniformity and high effluent quality.
34
3.03.04 Buffer Tank:
The clarified effluent then gets collected into the Buffer Tank (Diameter‐ 2.75 m, Height‐ 3 m) made of RCC. Acid & Alkali is dosed in the Buffer Tank to adjust the pH of the effluent. From the Buffer Tank effluent is pumped to the Anaerobic System/Reactor for anaerobic digestion.
3.03.05 Anaerobic System/ Reactor:
Effluent from Buffer Tank is fed to the Anaerobic Reactor to achieve the anaerobic digestion.
Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion reduces the emission of landfill gas into the atmosphere.
Anaerobic digestion is widely used as a source of renewable energy. The process produces a biogas, consisting of methane and carbon dioxide. Bidder is to provide the scheme suitable for biogas production.
Anaerobic excess sludge can be withdrawn from the system. The treated effluent flows by gravity into a Pre‐Aeration Tank prior to be introduced in the Aeration Tank with Surface Aerators.
3.03.06 Micro‐Fiber Removal Unit (DAF Unit)
In DAF unit, atmospheric air is introduced via air blowers into the Paper Machine Effluent for dissolving oxygen. In this process, microfiber & other primary contaminants are removed from the Paper Machine Effluent. DAF underflow sludge would be pumped via Two (2) [1 W + 1 S] horizontal centrifugal pumps each of capacity 15 LPM and 10 m head to the Sludge Mixing Tank.
3.03.07 Collection cum Equalization Tank with Transfer Pumps :
After fiber removal from Paper Machine Effluent, it is taken in a Collection cum Equalization Tank (Length‐ 5 m, Width‐ 9 m, Depth‐ 2.5 m) made of RCC along with boiler house effluent. Mixing is provided in the equalization tank by means of air grid for homogenization of the effluent. Thereafter resulting effluent is pumped via Two (2) [1 W + 1 S] horizontal centrifugal pumps each of capacity 100 m3/hr and 10 m head to the Reactivator Clarifier (Primary Clarifier) unit.
3.03.08 Reactivator Clarifier :
One (1) Reactivate Clarifier of 10 m diameter, which is a high rate effluent treating clarifier, produces treated effluent of highest quality with minimum time space & chemicals. In this, coagulant & polymer is dosed & effluent is retained in intimate contact for a prolonged period of time in draft & cone sections of the solid contact part of clarifier.
The intimate contact between the effluent, coagulant & polymer causes the chemical reactions to proceed at a rapid rate with a minimum of treating chemicals. Furthermore by contacting water
35
with the great volume of sludge in recirculation, maximum clarification of the water can be achieved by the adsorptive properties of the sludge or flocs formed.
Settled sludge will be moved continuously along the floor towards center of unit by means of a slowly rotating scrapper, which covers the entire floor area the accumulated sludge will be transferred to pockets, which concentrates sludge thereby reducing the total amount of blow down. The excess sludge will be removed from time to time to avoid built up of it. The clear overflow from Reactivate clarifier gets collected in the Aeration Tank. Each clariflocculator shall be designed for an average flow of 100 m3/hr with the ability to operate at 20% overloading condition when required.

3.03.09 Aerator Tank/ Aerated Lagoon and Surface Aerators:
One (1) no. aerator tank or aerated lagoon (Length‐ 25 m, Width‐ 25 m, Height‐ 3 m, Capacity‐ 1850 m3) with required no. of aerators (Bidder to specify the exact no.) useful for powerful pumping action to transfer the oxygen in order to break up the clarified effluent (Primary Clarifier Overflow) into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater. At the same time, the oxygen enriched water is dispersed. Aerator may be floating or fixed type. Bidder is to mention intimate details of surface aerators.
The biological treatment takes place in the Aeration Tank where soluble organics are degraded aerobically by microorganisms. The COD to BOD ratio in the present effluent is high, but it is
36
assumed that the major contributor for COD here is cellulose which is biodegradable with specific bacterial population acclimatized with the available cellulosic organics.
In order to ensure required population of bacteria in AT, i.e., Mixed Liquor Suspended Solids (MLSS) and also Food to Micro‐organisms ratio (F/M), part of the settled sludge from Secondary Clarifier (Activated Sludge) will be re‐circulated back to aeration tank.
Diffused aeration will provide desired oxygen to microorganisms. The aerobic environment in the reactor is achieved by the use of fine bubble diffusers, which also serves to maintain the reactor contents in a completely mixed regime. The diffusers shall be retrievable type for the ease of maintenance keeping the aeration tank on continuous operation.
Treated effluent will now flow to Secondary clarifiers.
3.03.10 Secondary Clarifier:
One (1) Secondary Clarifier of 8 m diameter where Aeration Tank over flow effluent is diverted for separation of sludge and liquid.
The clarifier is a circular sedimentation tank with scrapper mechanism where solids get settled at the bottom. The scrapper shall be peripheral driven with motor and rotor with wheel rotating on the clarifier periphery wall. The supernatant from the clarifier overflows uniformly over the peripheral launder.
To operate the process in continuous basis and maintain the activated biomass in the aeration system, a part of sludge from the clarifiers is re‐circulated back to Aeration Tank while the excess biological sludge is sent to Sludge Mixing Tank. Secondary Clarifier overflow is collected in an effluent holding tank.
3.03.11 Holding Tank:
One (1) Secondary effluent Holding Tank (Diameter‐ 8 m, Height‐ 2.75) made of RCC.
