| Shandong Ludao: Reduce Pulp Dissolved Organic Matter |
Excessive dissolved organic matter in pulp is the core cause of water system pollution and paper quality deterioration. In pulping and recycling papermaking process, degraded cellulose, lignin decomposition products and residual organic additives will form soluble organic substances mixed in pulp and circulating white water. Accumulated organic matter will raise water COD value, breed a large number of harmful bacteria, accelerate slime generation, aggravate mesh and roller fouling, and induce paper spots, holes and odor defects. Long-term accumulation of organic pollutants increases sewage treatment load, raises environmental treatment cost, and makes enterprises face discharge supervision risks. Conventional flocculants can only remove large suspended particles, have poor removal effect on tiny dissolved organic molecules, and easily produce floc residue affecting pulp purity. Shandong Ludao Energy Technology Co., Ltd. provides efficient dissolved organic matter removal solutions. By adopting targeted organic trapping and degradation technology, we adsorb and decompose soluble organic molecules in pulp and white water, reduce water COD index fundamentally, inhibit microbial reproduction and slime growth. The solution improves pulp cleanliness, reduces paper organic odor and spot defects, lowers sewage treatment pressure, cuts environmental protection operating cost, and helps factories realize low-pollution recycled papermaking production. |
