J.K.Paper Mills

PD : What technologies and strategies has your mill implemented to reduce water consumption effectively?

SM : a. Disc filters in paper machines for recycle of machine back water.

         b. Use of reclaimed water in Pulp Mill, Paper machines, hydro pulpers and other process area.

         c. Use of Sewage treated water (STP) as cooling tower make up in place of Fresh Water.

PD : How does your mill approach water recycling, and what percentage of water is generally reused within your production process?

SM : a) All Paper Machines back water is being pumped and recycled at water Reclamation Plant.

        b) Total generated reclaimed water from Paper Machines is being used (100 %) in different process by replacing Fresh Water

PD : What types of final water treatment processes does your mill use, and how do you ensure compliance with environmental standards?

SM : Incoming water is being drawn from river and clarified through different clarifiers using coagulants-Alum, PAC and polyelectrolytes. We are maintaining water parameters like turbidity, residual chlorine and pH as per IS standards (IS 10500 : 1991).

PD : How does your team maintain water quality throughout the production process, and what challenges do you face in doing so?

SM : Our team is facing challenges like sudden rise of incoming river water turbidity in rainy season and in summer floc rising problem in clarifiers

PD : What are the primary sources of water pollution in your mill’s papermaking process, and what measures are in place to mitigate these effects?

SM : Pulp Mill, Soda Recovery and Paper Machines are contributing for water pollution. We have adopted ITOT for process optimization as well as chemical dosing optimization.

PD : How do fluctuations in water availability, such as during droughts, impact your production process, and what contingency plans does your mill have in place?

SM : River Nagavali is a perennial river and receive rainwater time to time in summer too. Though the river level decreased during summer compared to other seasons, but sufficient water is flowing in Summer.

As sufficient water is available in the river during summer, hence, no impact in production process and no contingency plans.

PD : How does your mill handle wastewater, and what methods do you use to minimize its impact on local ecosystems?

SM : The generation of Wastewater from different sections of Mill is reducing year over year by implementing different water saving schemes. All generated Wastewater from different sections being collected and treated in our State of Art double stage Aeration with Tertiary treatment facility in our ETP and as a result, our quality parameters of treated effluent are far below the prescribed Norms of State Pollution Control Board.

Hence there is no impact on local ecosystems. In the same way, we are collecting all sewage from our colony and pumped to sewage treatment and the treated sewage water is again used in our process in place of fresh water.

PD : What role does regulation play in water management at your mill, and how do you adapt to changing regulations on water usage and discharge?

SM : We are consuming water as much lower of our permitted limits and discharging the final treated effluent which is far below to the prescribed limits of OSPCB.

PD : Could you share any recent innovations your mill has implemented in water management, and how have they affected sustainability and operational costs?

SM : a. Sewage treatment plant.

         b. Disc filters in paper machines

         c. Implementation of water consumption/saving schemes in our different processes.
