Gain continuous control over your pulp and paper manufacturing process.

 

The pulp and paper industry is one of the largest industrial consumers of water, requiring 64,000 litres per ton of paper. Aside from wood fibers, water is the most important raw material in the pulp or paper mill. Simply put, pulp and paper manufacturing is impossible without water at every step of the production process—in specific tasks from pulping and bleaching to slurry dilution and fabric showers, in steam and power production for thermal and mechanical processes, as well as general operation uses such as materials transport and equipment cleaning.

Hach® offers comprehensive water analysis solutions to paper mills, including manufacturers of corrugated paper, corrugated cardboard, tissue mills, kraft mills, and non-woven manufacturers of products such as baby diapers, disinfection wipes and more. Despite the broad range of paper product applications, the entire pulp and paper industry shares two main goals when it comes to water use: conserve fresh water by reusing as much process water as possible, and treat wastewater to comply with regulations and protect local resources. To accomplish this, having reliable tools and data is key.

 

From laboratory analysis to process solutions, Hach’s accurate, easy-to-maintain instrumentation, comprehensive test kits and high-quality prepared reagents are based on nearly a century of innovation and a desire to provide the simplest way to results pulp and paper companies can trust.

 

紙漿和造紙工業是極大的工業耗水產業之一，每噸紙需水 64,000 公升。除了木纖維之外，水是紙漿或造紙廠中最重要的原料。紙漿和造紙生產過程的每一步都需要水 - 從製漿和漂白到漿料稀釋和織物噴淋的特定任務，用於熱力和機械過程的蒸汽和電力生產，以及一般操作用途例如物料運輸和設備清潔。

 

Hach® 為造紙廠提供全面的水分析解決方案，包括瓦楞紙、瓦楞紙板製造商、衛生紙廠、牛皮紙廠以及嬰兒尿布、消毒濕巾等產品的不織布製造商。儘管紙產品應用廣泛，但整個製漿造紙行業在用水方面有兩個主要目標：透過重複利用盡可能多的製程水來節約淡水，並處理污水以符合法規標準並保護當地資源。要實現這一目標，擁有可靠的工具和數據是關鍵。

 

從實驗室分析到線上監測方案，Hach準確並容易維護的分析儀器、測試套組和預製試劑，致力於提供最簡單的方法來協助紙漿和造紙公司取得可靠分析數據。

 

Featured Applications for the Paper and Pulp Industry 主要應用

 

Water Supply  供水
Monitor and control the microbial content of the raw water coming into your plant to minimize expensive post-input treatment processes and protect vital equipment. 

Steam and Power  蒸汽與電力
Keeping microbial contaminants out of your system and away from equipment like shower bars, paper-making fabrics, rolls and vacuum elements helps you keep your production online and your costs low.

Wastewater Treatment  污水處理
From Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD) content to phosphorous, bacteriological and specialized contaminants, Hach provides the compliance monitoring you need to maintain a sustainable environmental impact and remain compliant with all applicable regulations.

 

Water Supply Conditioning  供水調節

Because more than 90% of water used in the paper making process is sourced from the local environment, incoming water quality, including organic content, chemistry, dissolved oxygen and flow, varies with the weather and the seasons. Confident measurement and management of fresh water enables efficient, cost-effective production of high quality pulp and paper, whereas poor or unknown water quality creates costly consequences. Real-time analysis starting at raw water intake enables pulp and paper mills to:

• Optimise biocide/disinfectant dosage
• Detect changes to incoming water quality and take preventive action (e.g. the addition of chlorine to minimise bacterial and slime growth)
• Monitor plant efficiency and production performance
• Guard against in-plant corrosion and in-plant scale
• Check potential of non-ionic inorganics to cause in-plant deposits
• Assure effective filtration

Steam & Power  蒸氣動力

Because of the energy consumed to heat, pump and circulate water, and because of the key machinery at risk of scale and corrosion, careful analytics at this stage is a high-value priority. Additionally, because water is demineralised, treated and reused throughout the papermill, changes to parameters during steam generation have costly repercussions: boiler feed water must be purified to minimise corrosion, while treated steam condensate can be reused in the steam system. Continuous monitoring enables your operation to make informed process decisions and manage costs by:

• Monitoring oxygen scavengers and controlling oxygen scavenger dosing to avoid corrosion as well as overdosing
• Controlling the addition of phosphate to reduce corrosion and deposits
• Avoiding damage to turbines and tubes caused by precipitates
• Detecting efficiency loss in ion exchangers or membrane systems used for pre-treatment
