What Are the Quality Requirements of Industrial Water

Despite the digitalization that has led to a move away from printed products, the pulp and paper sector remains one of the largest users of industrial process water in the United States and the second largest in Europe. Water is closely linked to 85% of the three stages of paper production, namely pulp production, pulp processing and paper/board production and related cooking, bleaching and washing activities. A large amount of water consumed in the pulp and paper industry is only used for treatment, resulting in the formation of large amounts of contaminated wastewater. Removing contaminants from your intake water is an essential first step in ensuring efficient heating and cooling, improving operational efficiency, and maintaining compliance with water quality standards. It can also help in the recovery and recycling of process water and materials containing wastewater. Depending on the product manufactured and the quality of the raw water in the area, different treatment technologies are required. For example, for medicine, electronic manufacturing and food processing, deionized water is an essential component. Called ultrapure water (EUP), almost all minerals, dissolved gases and dirt particles are removed from the water that could otherwise interfere with the production of accurate and sensitive products such as printed circuit boards. Earthwise Environmental has been a leader in the water treatment consulting and management industry since 1995.

Our many partnerships with industry associations and research institutes consistently place us at the forefront of the industry, including evaluating new water monitoring and treatment technologies and developing more sustainable water quality solutions for healthcare, manufacturing and commercial real estate. Industrial water and wastewater are a by-product of industrial or commercial activities. Whether it`s the food we eat or the products we consume, water is needed for almost every stage of production in a variety of different industries. The resulting wastewater must be carefully managed. We work with our clients to develop practical, strategic and tailor-made solutions to water quality challenges. Our employees include three certified water technologists, recognized experts who are committed to providing the highest level of service in the industry. From water purity testing and water drinkability testing to training your employees on water management best practices, we can help you meet and exceed your cost reduction, sustainability and compliance goals. This process is usually carried out by two ionized resin beds that are opposite in their charges: cationic resin (negative) and anionic resin (positive).

The positively charged ions are removed from the solution by the cationic resin in exchange for a chemically equivalent amount of hydrogen ions. Negatively charged ions are removed from the anionic resin in exchange for a chemically equivalent amount of hydroxide ions. The hydrogen and hydroxide ions introduced into this process combine to form pure water molecules. Deionization (DI) is the removal of all ionized minerals and salts from a solution through the ion exchange process. Since most non-particulate contaminants in water are dissolved salts, deionization produces high-purity water that generally resembles distilled water. Deionization filters work by replacing positive hydrogen and negative hydroxide molecules with positive and negative impurity molecules in water. Positive chemicals such as sodium, calcium, iron and copper change places with hydrogen molecules, and negative chemicals such as iodine, chloride and sulfate change places with hydroxide molecules. Textile manufacturing has been called “one of the world`s biggest polluters,” with textile factories accounting for one-fifth of the world`s industrial water pollution. In China, for example, up to 20% of the country`s industrial water pollution comes from dyeing and textile processing. It is estimated that up to 20,000 chemicals are used for textile production worldwide. Industrial sites, including pulp and paper mills, generate large amounts of organic waste that can be converted into renewable energy in the form of methane. Anaerobic digestion is the process by which organic matter is broken down in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic fermenter.

Industries with high water consumption and treatment needs include: brewer`s water and carbonated beverage water; the dairy industry; sugar mills and refineries; textile production; pulp and paper mills; oil and gas; the automotive and aeronautics industries and many others.

Anaerobic treatment of plant wastewater is widely accepted, but is only applied to a selected few streams. Chemical oxygen demand (COD) removal rates in complete reactors range from 30% to 90%, with the highest COD removal rates achieved with condensate fluxes from chemical digestion (75-90%) and paper wastewater (60-80%). Regular inspections and repairs are necessary, but not sufficient, to achieve optimal efficiency and performance of the water system. It is important to have a good water quality monitoring system that includes water testing and other solutions. Membrane technology plays an important role in the production of all types of pure water. Depending on the feed water available, other membrane technologies can be integrated as pre-treatment technologies. Ultrafiltration (UF) or microfiltration (MF) technology can be effectively used as a pretreatment for reverse osmosis (RO), depending on the type and variability of the water treatment system supply. When sewage from these springs enters the marine environment, it usually occurs through an estuary, an area where fresh water from the land mixes with seawater. There are a number of industrial water solutions, and the choice is determined by several factors: the quality of the raw water in the area, regional regulations for the plant, the type of product manufactured and the purity of the water needed, among others.

For example, the solutions needed to obtain ultrapure water for semiconductor manufacturing differ significantly from the solutions needed to treat wastewater from pulp and paper production. Often, water solutions used for municipal water treatment, such as membranes, are also used for industrial applications. In addition, industrial water treatment solutions tend to be more diverse than municipal alternatives due to the wider range of pollutants, their concentrations and the temporal variability of industrial wastewater. Below, we have listed five industrial water solutions and processes. Cooling systems are used to remove heat from processes or equipment. Heat dissipated from one medium is transferred to another medium or process fluid, which is usually water. According to the SUEZ Water Technologies manual, the driving force of heat transfer is the temperature difference between the two supports, which is between 10 and 200 degrees F in most cooling systems. Many properties of water, including the behavior of the impurities it contains, are affected by temperature. As a result, a system`s tendency to corrode, scale, or support microbiological growth is also affected by water temperature. Industrial water quality requirements vary considerably depending on the application, region and local governance. For example, ultrapure water for food and beverage production is different from water needed for oil and gas extraction and processing.

Even within these segments, water quality varies from food to food – for example, from dairy to confectionery and beverages, from soft drinks to alcoholic beverages. Coupled with local and global regulations, it is a complex mix of quality requirements. However, water in the food industry should meet the requirements of local standards for drinking water or the requirements of the World Health Organization (WHO) guidelines for drinking water quality. There are many uses of water for industry. Raw water entering an industrial facility often needs to be treated to meet strict quality specifications. In the meantime, the wastewater must also be treated to make it reusable or disposed of. .
