Water & Wastewater

Manufacturing and other industries use water during the production process for either creating their products or cooling equipment used in creating their products. Industrial water is used for fabricating, processing, washing, diluting, heating, cooling, cleaning, rinsing, manufacture, consumption. Industrial water treatment is a process used to optimize most water-based industrial processes, As aforementioned, Industrial water treatment is also referred as to industrial water processing.

Industrial water and wastewater come from economic activities. Whether it's the food on a plate or things we use, water is a fundamental commodity for nearly every step of production across ubiquitous industries. Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use

Untreated water that is incorporated in any industrial facility is a high-risk factor in manufacturing processes. Wastewater will pollute drinking water resources while the annual increase in population and drinking water demand. As many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes, and oceans, there is a responsibility to ensure pollutants are removed and minimized. Untreated water must be carefully processed. Unclean water can have a negative effect on product quality.

Some of the most widely-used water treatment systems commonly include: Boiler feedwater treatment systems, Cooling tower water treatment systems, Raw water treatment systems - Wastewater treatment systems

The goal of industrial water processing

The primary purpose of water processing is to avoid the occurrence of scaling, biological contamination, and corrosion that take place on industrial process equipment such as boiler feeds, piping, and cooling towers from deterioration or failure from dangerous mineral salts. Surfaces of pipes and vessels can be affected by corrosion and steam boilers can scale up or corrode.

in most cooling systems, is in the range of -15-95 degrees C. Many of the behavior of the contaminants in the wastewater are affected by temperature. As a result, the tendency of a system to corrode, scale, or support microbiological growth is also affected by water temperature.

The ultimate goal is to reduce operating costs and risks. Poor water treatment can cause serious damage to the process and the final results. Industrial water treatment provides various facilities and applications with a myriad of benefits that improves labor and equipment productivity.

Advantages of industrial water processing

Unclean water can have a negative effect on product quality. Helping to meet local codes and requirements. Prolonging the equipment process. Saving water, chemicals, power & energy. Reducing labor costs. LEFOO has a great deal of knowledge and experience with a multitude of pressure measuring and pressure control technologies that can be used to meet strict requirements. Some of the possibilities:

Industrial water treatment

There are many uses of water for industry.  Common industrial water treatment systems typically include raw water treatment systems. Cooling tower treatment, Boiler feedwater systems, Wastewater treatment systems

Water treatment in Food and Beverage Industries, BreweriesDairy Industry

Reverse osmosis: During the reverse osmosis purification process, a semi-permeable membrane is used to remove ions and unwanted particles. This process can remove both chemicals and bacteria, resulting in potable water safe for food and beverage production. The permeable membrane filters contaminants through a process called size exclusion, where particles of a specific size cannot pass through.

Other water processing include Ion exchange, Carbon filtration, Deaeration, UV disinfection

Steel industry

The Cooling waters are inevitably contaminated with ammonia and cyanide. Production of coke from coal in coking plants also requires water cooling and the use of water in by-products separation. The conversion of iron or steel into sheet, wire, or rods.  Contaminants include hydraulic oils, tallow, and particulate solids.  surface treatments such as galvanization or painting generate Wastewaters include acidic rinse waters together with waste acid.

Mine industry

The principal waste-waters associated with mines and quarries are slurries of rock particles in water.  Oils and hydraulic oils are also common contaminants. such as coal washing to separate coal from the native rock using density gradients, can produce wastewater contaminated by fine particulate haematite and surfactants.

Organic chemicals industry

A range of industries manufactures or uses complex organic chemicals. These include pesticides, pharmaceuticals, paints and dyes, petrochemicals, detergents, plastics, paper pollution, etc. Wastewaters can be contaminated by feed-stock materials, by-products, product material in soluble or particulate form, washing and cleaning agents, solvents, and added value products such as plasticizers.

Oil and gas industry

Water is a raw material used and produced in high quantities in the oil industry, from extraction activities through to refineries and petrochemicals. Uses include injection water, production water, process water, wastewater, rainwater, cooling water, tank cleaning water, and others.

 High purity water grades

high purity water is used to describe a range of pure water specifications. Each grade of pure water is used in a number of applications, that include:

Deionized Water – medium pressure boiler feed, renal dialysis make-up, battery top-up;

Purified Water – pharmaceuticals, cosmetics, chemical manufacturing;

A pyrogenic Water – vial washing, tissue culture, water for injections;

High Purity Water – high-pressure boilers, combined heat, and power systems, laboratories;

Ultrapure water – microelectronics, supercritical boilers.  The ultrapure water is used in silicon wafer industries, computer, Aerospace industry

Clean water in future

In fact, around 1 billion people on the planet hard to have access to clean water.

Lack of surface and groundwater availability due to drought has caused many shortage issues. Untreated wastewater also contaminates clean water sources. To improve sustainability, many industries are looking into water recycling and reuse strategies. While water scarcity is a major threat to businesses.
