APP-China's Jinhai pulp and paper facility, the largest pulp mill in China and the world's largest single-line pulp facility, has implemented a number of integrated water conservation strategies and advanced water treatment technologies that have effectively made the facility a world leader among pulp and paper mills in terms of water efficiency and discharge.
Converting to recycled water for cooling towers requires proper planning and a good understanding of the challenges involved. Successful projects have resulted in savings of 10-30% of costs over fresh water and more importantly provided better protection of water contacted equipment.
In situ biological treatment at the Alpha Explosives site in California appears promising for remediation of nitrate and perchlorate. Periodic reagent addition to injection wells in two source areas over the past six years has removed up to 48% and 75% of the nitrate in the source areas, along with 61% and 82% of the perchlorate.
Water quality trading continues to gain interest among industry and agricultural producers as a viable market-based alternative to control water pollution. This approach is based on the idea that pollution sources in a watershed face very different costs to control the same pollutant.
An underused control strategy that offers significant benefits is Time-Proportional Control (TPC). Unlike traditional proportional or even PID control that require a varying output to a modulating control device, time-proportional control can achieve a proportional control response to process variation using an on/off device by varying on and off times in a defined control period.
Owners of a large uptown commercial building on Madison Avenue in New York City recently installed new automatic self-cleaning screen filters for their HVAC. The system includes new automated controls to streamline operation and lower costs.
Desalination plant flow control and treatment expenditures are now just 1.5 percent of the $340 billion dollar flow control and treatment market.
In 2012 the U.S. Environmental Protection Agency levied $252 million in civil and criminal penalties for violation of environmental rules. At the same time, the agency helped reduced air, water and land pollution by several billion pounds, according to the agency.
In a case monitored by the industrial water community, the U.S. Supreme Court ruled last month that the flow of polluted stormwater from a channelized section of river into a "natural" stretch of the same river does not constitute a "discharge of pollutants" under the Clean Water Act (CWA).
Culligan Matrix Solutions, a division of Culligan International Co. focused on water treatment for commercial and industrial markets, is expanding its mobile water treatment solutions business in response to increasing demand for this service.
The Excel Bottling Company in Breese, IL, recently installed a new gas-fired modular boiler. The "once-through" fin-tube design heats a smaller volume of water more efficiently than other boilers and provides "on-demand" steam capability.
