The pulp and paper industry consumes water in the tens of cubic meters per ton of paper produced, with older and less-integrated mills at the high end—that is what makes water reuse a board-level procurement topic Closed-loop water systems can cut freshwater intake by up to 70%, but only if effluent quality is verified continuously…
Key Takeaways: – Converting to a closed-loop water system typically cuts freshwater intake by roughly three-quarters — but dissolved solids concentrate at the same time, so monitoring gets harder exactly when it matters more – Open systems carry materially higher annual freshwater and effluent treatment costs than equivalent closed-loop installations – In most current tariff…

A Diagnostic Guide by Shanghai ChiMay” date: 2026-06-26 type: 疑问标题型 What Causes Foam Buildup in Recycled Paper Mill Process Water? A Diagnostic Guide by Shanghai ChiMay Key Takeaways: – Foam in recycled paper mill process water is rarely a single-cause problem; it is the…
Tissue paper manufacturing has uniquely tight water quality requirements because softness, absorbency, and hygiene attributes depend directly on freedom from deposits and microbial activity. Through-air-dried (TAD) tissue manufacturing demands continuous monitoring of conductivity, pH, and ORP at the wet end to prevent fabric clogging and brightness loss. Shanghai ChiMay multi-parameter sensors are widely deployed in…
Black liquor recovery is the energy and chemistry backbone of kraft pulp mill operation. The recovery boiler fires concentrated black liquor to generate most of the mill’s steam and power, which is what makes kraft mills largely energy self-sufficient. Water quality monitoring at five distinct points in the recovery cycle directly governs evaporator efficiency, recovery…
