It’s no secret to those within the U.S. water treatment industry: the ability to deliver clean drinking water is wholly dependent on the nation’s infrastructure for doing so. But much of the general public is unaware of just how critical this buried infrastructure is.
In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality.
Long Island has faced 1,4-dioxane contamination in its drinking water for months. Now, there is a whopping price tag attached to dealing with the problem.
Public utilities are under extreme pressure and their needs, which fall into the critical category, are common.
Climate change, drought, and overuse are taking a heavy toll on the Colorado River and those who depend upon it.
In the developed world, potable water is delivered to people via a complex infrastructure consisting of water catchment, water treatment, water storage (reservoirs, towers), and water distribution (pipes). The first two elements are well understood; what is less understood is what happens to water as it journeys to the tap.
There will always be some debate between public officials and privately-run water and wastewater systems. In Kentucky, this has manifested into controversy over a new bill.
It’s not uncommon for the U.S. EPA to step in when local wastewater operations struggle to adequately remove pollutants before releasing effluent into waterways. In Mississippi, however, even that federal intervention has failed to yield enough progress.
In 2012, the Town of Francesville in Indiana contacted Air Diffusion Systems to provide a solution for several suspended solids violations and energy efficient treatment.

In recent years, the wastewater treatment industry has made a concerted effort to become more energy efficient and engage in sustainable practices. Now, a new process gives wastewater operations another avenue to reuse their byproducts.
Often located on coastlines or near large water bodies, wastewater treatment plants are among the most susceptible institutions to storm surge and are increasingly threatened as sea levels rise. With the threat of these coastal hazards only set to increase, these facilities must add new provisions to protect themselves.
In mid-2016, shortly after the U.S. Environmental Protection Agency (EPA) revised the health guidelines for perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) to 70 ng/L (or ppt), the township of Horsham, Pennsylvania, together with Horsham Water and Sewer Authority (Authority), the Township’s public water supplier, set a goal of reducing these two contaminants to non-detect (ND) level in all drinking water supplied.
U.S. and Canada industrial sector withdrawals have declined 30 percent over the last three decades to 152 BGD. This trend, which is expected to continue, has been sparked by water-related technology improvements at facilities, company strategies to mitigate water supply risks, and outside pressure to better manage wastewater effluent through regulations and rising discharge costs.
Well-known New York waterways such as the Hudson River, Susquehanna River, and even Niagara Falls are taking on untreated sewage at an alarming rate, thanks to increasingly heavy rains and outdated infrastructure.
California should invest in modern water-use tracking systems and address privacy concerns as part of a larger data-focused initiative to get a better grip on its constrained water resources, according to a report that could have repercussions beyond the state.

Using on-site sodium hypochlorite generation technology to make oxidant for water and wastewater treatment is cost-effective, safe, and environmentally responsible. But, as with any piece of equipment, choosing the right one and caring for it properly impacts both life cycle costs and effectiveness. We talked with David McWalters, Field Service Manager-Americas, De Nora, to learn more.
Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO4-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.
