Pile Cloth Media Filtration For Clean Utilities
Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

LATEST INSIGHTS ON WASTEWATER
-
The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
-
Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
-
While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
