pH Measurement of Wastewater Treatment at Pulp
Pulp and paper plants consume large volumes of water, and the treatment of wastewater from these plants is a serious environmental concern. To treat this wastewater, suspended solids (SS) are separated and precipitated in a precipitation tank using flocculation agents. During this process, the pH value
pH Measurement of Wastewater Treatment at Pulp and Paper Plants Industry: Pulp & Paper Industry Product: pH Introduction Introduction Pulp and paper plants consume large volumes of water, and the treatment of wastewater from these plants is a serious environmental concern. To treat this wastewater, suspended
pH Measurement of Wastewater Treatment at Pulp and Paper
Wastewater at pulp and paper plants contains effluents from the pulping, bleaching, papermaking, and recycling processes. The treatment of this wastewater involves pH level control, solid-liquid separation, oxidization, and other processes, and depends on such factors as the levels of organic, reducible and suspended matter in the wastewater as

To treat this wastewater, suspended solids (SS) are separated and precipitated in a precipitation tank using flocculation agents. During this process, the pH value needs to be
Modeling and Control of pH in Pulp and Paper Wastewater
Keywords: Biological Treatment, pH, MATLAB, Cascade Control . 1. Introduction . Pulp and paper industry is the greatest industrial polluter in terms of wastewater volumes and organic discharges. The general characteristics of the pulp and paper industry effluent can be listed as: 1) high lignin content, 2) high
For a large, multi-national company that produces personal care and tissue products, monitoring pH of pulp mill wastewater is critical at several stages during the treatment process. This case study explains the challenges that they have in monitoring pH in their wastewater treatment process, and how intelligent pH sensors have helped them to overcome maintenance challenges.
pH measurements in Pulp & Paper Industry | Endress+Hauser
For pulp to bind properly and form the paper sheet, pH measurement in the headbox is significant. pH is controlled in the headbox and adjusted with Alun (or H 2 SO 4) to around 4.5 for proper binding of fibres into paper sheets. Incorrect pH can also affect the printing qualities or cause discoloration when printing.
Due to the long sensor lifetime and greater reliability, mill managers calculate that operating costs for the new system are half of what they were prior to use, and are planning to convert all pH measurement points at the facility to METTLER TOLEDO sensors.

Turbidity of White Water - Control White Water Quality
Turbidity of White Water White Water Quality. In the sheet-forming step of papermaking, excess water from the dewatering process is called white water. Significant economical and environmental benefits can be realized by optimizing the efficiency of the paper making process.
Wastewater pumps are used in a variety of industrial, commercial, military, and maritime applications. Examples include agriculture and horticulture, aerospace and defense, construction, food processing, hydrocarbon and petrochemical, power generation, pulp and paper, and semiconductor applications.
Paper and Pulp Analysers | Process Instruments
Process Instruments is present in all markets where water is processed. All of these markets present their own challenges to monitoring and control and none more so than paper and pulp. With the high level of solids often present, monitoring anything in the water in the paper industry is challenging.
ABB has launched a new range of colour-coded sensors that makes it easy to choose and manage the optimal pH measurement solution. The application driven designs are categorised into three groups: the entry-level 100 series for
- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
