Paper and Pulp

It is estimated that 40 – 60 cubic meters of wastewater is discharged in the production of one ton of paper. Paper and pulp industries around the world generally extract water from ground or a neighboring river and dump it back into the river. Discharge of under-treated wastewater has several adverse effects on surrounding water bodies like increase in temperature, decrease in dissolved oxygen and decrease in photosynthesis by aquatic flora and reducing the potability of water

Wastewater from paper industries majorly contains Lignin and its derivatives, which imparts highly colored effluent from pulping, bleaching and chemical recovery stages of the plant. Currently, a combination of Aerobic and Anaerobic treatment methods is used to treat wastewater from paper mills. While Color can be removed effectively by coagulation, fungal treatment, chemical oxidation, and ozonation, Chlorinated phenolic compounds and adsorbable organic halides (AOX) can be efficiently reduced by adsorption, ozonation and membrane filtration techniques. However, these technologies require intensive capital investment and thus, are not cost effective

Richcore’s novel enzyme technology, RichEcosol can be effectively used for reducing Color, COD/BOD and sludge in industrial wastewater without any additional capital expenditure
