WASTE WATER - Filter art
Industrial wastewater re-use poses challenges because initial feed water characteristics can differ from facility to facility. Water filtration systems differ because of the incoming water conditions and the purity requirement for end use. Although wastewater re-use systems are specific to each plant, Filter Art’s particle filtration systems can provide effective water processing to increase plant efficiency and lessen strain on local water resources and membrane filtration.
As an example, in the oil and gas industry, water discharge may contain hundreds of parts per million (ppm) of oil and total dissolved solids levels over 200 ppm, whereas discharge water in the pulp and paper industry may contain more than 1,000 ppm of fibrous solids. In addition, the required water purity may vary. Users may need the water discharge to be slightly upgraded (25 to 50 percent of the solids removed), upgraded to potable (drinkable) standards, or brought to ultrapure water quality.
Wastewater Particle filtration
Particle filtration is a physical or mechanical process that separates solids from fluids. Particle filtration typically is defined as the filtration of particles larger than 1 micron and is used as one of the first filtration steps in industrial wastewater treatment. Common technologies that are used for fine-particle filtration include bag filters, cartridge filters, multimedia filters, and self-cleaning filters.
Because industrial wastewater characteristics can vary so dramatically, depending on the industry, it is common to use multiple technologies to process the water. The properties of the solids in the water, including particle size, shape, density, stickiness, and quantity, as well as other materials in the water such as oil, determine which filter technologies are used.
