Adoption of Green Technology
to keep our environment clean and green

Complete recycling of paper machine effluent to pulp mill by passing through Saveall.

100% recycling of Paper machine backwater to Pulp mill by passing through Saveall and settling in a clear water tank i.e. 2200 m3/day reduction in freshwater consumption.

Installation of Efficient IBS showering system on the paper machine, wet end to reduce water consumption drastically.

Water consumption was reduced to 2200 m3/day from 2900 m3/day after installation of the IBS showering system i.e. 700 m3/day reduction.

Use of ETP treated effluent after Secondary stage for wet washing of raw material and wetting of Bagasse wet bulk storage.

100% reuse of treated secondary stage ETP effluent for wet washing of raw material and wetting of Bagasse wet bulk storage i.e. 4000 m3/day reduction in freshwater consumption.

Installation of Reverse Osmosis (RO) system followed by MVR (Mechanical Vapour recompression) system – Capacity 2000 m3day

  • Following the ZLD concept, after ETP tertiary treated effluent we have installed Single-stage RO followed by MVR for reject handing of the RO system and ATFD for sludge handling of MVR system. 
  • The reusable water recovery (TDS < 100 ppm) from the complete system will be 98%. 
  • The technology is completely new since the opex is very less as compared to conventional ZLD systems.
  • However, the same is under the fine-tuning stage.

Installation of state-of-the-art, DCS-based Biomethanantion plant from Hydrothane (Netherland) for High effluent load drains.

  • Effluent from Bagasse wet bulk storage and wet washing is treated in the Biomethanation plant before going to ETP and the recovered Biogas is used as a fuel in the boiler.
  • COD reduction – 80% and BOD reduction – 90%

Countercurrent washing in an unbleached section of Pulp mill.

Approximate 70% counter-current washing in a bleached section of Pulp mill.

Pulp mill unbleached section gland cooling is carried out with ETP treated effluent.

Black Liquor generated from Pulp mill is completely incinerated in a chemical Soda Recovery plant and Soda ash is recovered.
