Water and Sewage
Industrial Wastewater Treatment describes the processes used for treating wastewater that is produced by Industries as an undesirable by-product. After treatment, the treated Industrial Wastewater may be reused or released to a Sanitary Sewer or to a surface water in the environment. Some Industrial Facilities Generate Wastewater that can be treated in Sewage Treatment Plants. Most Industrial Processes, such as Petroleum Refineries, Chemical and Petrochemical Plants have their own specialized facilities to treat their Wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of Wastewaters into Sewers or into Rivers, Lakes or Oceans. This applies to Industries that generate Wastewater with High Concentrations of Organic Matter, Toxic Pollutants or Nutrients such as Ammonia. Some Industries install a pre-treatment system to remove some Pollutants, and then discharge the partially treated Wastewater to the Municipal Sewer System.
Most Industries produce some Wastewater. Recent trends have been to minimize such production or to Recycle Treated Wastewater within the Production Process. Some Industries have been successful at redesigning their Manufacturing Processes to reduce or Eliminate Pollutants. Sources of Industrial wastewater include Battery Manufacturing, Chemical Manufacturing, Electric Power Plants, Food Industry, Iron and Steel Industry, Metal Working, Mines and Quarries, Nuclear Industry, Oil and Gas Extraction, Petroleum Refining and Petrochemicals, Pharmaceutical Manufacturing, Pulp and Paper Industry, Smelters, Textile Mills, Industrial Oil Contamination, Water Treatment and Wood Preserving. Treatment Processes include Brine Treatment, Solids Removal (e.g. Chemical Precipitation, Filtration), Oils and Grease Removal, Removal of Biodegradable Organics, removal of other Organics, Removal of Acids and Alkalis, and removal of Toxic Materials.
Waste Water Treatment processes are characterized by continuous disturbances and variations that cannot be detected by Manual Measurements with the precision and within the time span necessary for maintaining proper operation of the facility. Typical Process Disturbances include process inputs and conditions such as variable Flow Rates, Chemical and Biological Composition, Temperature and Density. Instrumentation and Automatic Control allow continuous monitoring of Process Variables, Rapid Transfer of data to the Operator or Manager and Immediate Automatic Execution of Corrective Measures when needed. The use of Instrumentation and Automatic Control in growing nowadays, owing to the multitude of benefits that they confer in terms of Process Improvement, Equipment Performance, and Convenience to personnel.
