Reply: To reduce the emission concentration from the proposed project, the proposal has been revised. As per revised proposal, the WHRU/Auxiliary Boiler which was initially proposed is now removed from the proposal. However, to manage the steam requirement we propose to increase the LP Steam generation capacity from 55 Ton to 90 Ton of existing Turbine by reducing the extraction pressure from 10.5 bar to 3 bar by replacing the turbine. After this change there shall be no requirement of auxiliary boiler in the proposed expansion. As well Prilling tower stack design with respect to Stack height and Dia has been revised. Along with this adequate APCS are proposed to control the emission. Details of the plant wise APCS proposed as part of emission management plan is as mentioned in Table 1. Comparative table showing revision in emission load due to removal of auxiliary boiler, revising of Prilling Tower stack height and Dia, and emission management plan proposed is as shown in Table 2.

PPL shall install and commission an Effluent Treatment Plant (ETP) having capacity of 700 M3/hr for treatment of effluent generated from different process units. ETP shall be designed by NEERI, Nagpur.

PROCESS DESCRIPTION :

The combined effluent from process units of various sections passes through the effluent drains and shall be collected in the Central sump and pumped to Effluent Treatment Plant. The effluent shall pass through an Inlet chamber, bar screen, Grit Chamber and Oil & Grease trap prior to an Equalization Tank. The Equalization Tank shall be equipped with air diffusion system.

One dedicated facility for Lime solution preparation shall be available with screen chamber , Hoppers , belt conveyor , Bucket elevator, Screw conveyor and slurry preparation in Concentrated lime preparation Tanks , Lime Dosing Tanks, Lime Dosing Pumps and Control valves. Here the

Lime powder with 80 ~ 86% Ca(OH)2 shall be fed to the Conc. Lime Preparation Tank and Treated water added to make 20% Lime solution (approx). This 20% Lime solution shall be taken to Lime Dosing tanks and diluted to 10% (approx) by adding further quantity of Treated water.

Effluent from Equalization Tank shall be pumped to Flash Mixing Tank-1 where 10% lime solution will be added to raise the pH to 7 along with Polyelectrolyte as a coagulant and shall pass to Clariflocculator – 1. Supernatant of Clarifier 1 shall be passed to Flash Mixing Tank-2 for second stage of lime treatment and then to Clariflocculator – 2. Where the pH shall be raised to 10.5 by dosing further quantity of lime solution through Control valve-2. The final clarified overflow from Clarifier – 2 will be alkaline in nature with pH 10.5. pH of overflow water from Clariflocculator – 2 shall be corrected by adding sulphuric acid in pH Correction Tank where pH,phosphates,fluoride,TSS,TDS BOD,COD ,O&G shall be achieved as per CPCCB/OSPCB norms. Treated water will be used in ball mill of Phosphoric acid plant.

The Sludge from Clariflocculator – 1 and 2 shall be drained to Thickener and the thickened sludge will be pumped to Filter Press for dewatering. Sludge cakes from the Filter Press will be discharged to Sludge Storage Yard which shall be used in the DAP plant as a filler. Treated water quality shall be monitored by online pH meters. THEORY OF CHEMICAL TREATMENT

Chemistry of Phosphate Removal :

Phosphates will be removed from wastewater by precipitation as calcium salt using Calcium usually added in the form of lime i.e. Ca(OH)2. The primary reaction will be as follows,

2+ -3 3Ca + 2(PO4) Ca3(PO4)2 ------(A) When lime will added to water it will react with the phosphates to precipitate calcium phosphate Ca3(PO4)2. This reaction (A) will be expected as dominate in the first stage of treatment till pH 7.

However, the residual concentration of phosphates in water will be higher than discharge limits due to partial solubility of calcium phosphate at neutral pH range. Therefore second stage of phosphates removal at pH beyond 10 with lime will be envisaged where calcium ions will react with the residual phosphates to precipitate as hydroxylapatite Ca10(PO4)6(OH)2, shall be governed by the reaction (B).

+2 -3 - 10Ca + 6PO4 + 2OH Ca10(PO4)6(OH)2 ------(B) (Hydroxylapatite)

Chemistry of Fluoride Removal :

Calcium salts, including Ca(OH)2, CaSO4, and CaCl2 shall be used to precipitate fluorides as insoluble CaF2. The precipitation of fluoride using lime will be occurred as follows :

Ca(OH)2 + 2HF CaF2 + 2H2O ------(C)

stoichiometrically, the precipitation shall affect the reduction of fluoride levels to the limit of solubility of fluoride in the CaF2 system. But the equilibrium that shall affect the solubility of fluoride includes not only the CaF2 itself but also the species H2+F and HF-2 as well as the ion- pair CaF+. This results in presence of traces of fluoride after initial precipitation meriting a second stage of fluoride removal. The second stage shall affected by chemisorption of fluoride on calcium phosphate and by adsorption on hydroxylapatite. The presence of alkalinity and precipitable phosphates enhance the precipitation of fluoride in which the carbonate radical of the apatite complex, Ca(PO4)6.CaCO3, shall replace by fluoride to form an insoluble fluorapatite. Ca(PO4)6.CaCO3 + 2F- Ca(PO4)6.CaF2 + CO2-3 ------(D)

Ca(PO4)6 + 2CaF Ca(PO4)6.CaF2 ------(E) (Fluorapatite)

Since the precipitation of phosphate will be carried out simultaneously the process of co precipitation takes over in the second stage of treatment resulting in highly efficient removal of fluorides from wastewater. PROCESS FLOW DIAGRAM OF EFFLUENT TREATMENT PLANT, PPL CAPACITY: 700 M3/Hr
