What's Missing From Your Water-Monitoring Strategy?

When it comes to water quality monitoring, professionals in municipal, industrial, and agricultural applications might have distinctly different concerns about what they measure, but they all share a common concern about the cost and ease of obtaining that data. Fortunately, a new alternative for achieving water quality data and analytics with a high degree of autonomy, accuracy, and affordability is now available to all of them.

Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years

The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

High Recovery Reverse Osmosis Water Treatment For Industrial, Agricultural, And Municipal Applications

Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO.

Dual Auger System Eliminates Clogged Pumps Caused By Flushable Wipes

The Drake Pump Station, located in Saginaw, Michigan experienced chronic pump maintenance due to flushable wipes. Although the dry pit pump station represented only 0.1 million gallons per day (mgd) of flow in the city’s collection network, it required a substantial amount of servicing – up to three times a week. This consisted of two operators spending four hours manually removing rags in a confined space entry to clean out the clogged pump. It was a dirty, unplanned, and time-consuming task.

Maximizing Solids-Handling Performance Of Municipal, Commercial, And Industrial Pumps

The rise in the use of disposable wipes and other non-dispersible debris is driving the need for more efficient handling of solids in pumps at municipal lift stations and wastewater treatment plant headworks.

What To Know About Water Quality Analysis For Reverse Osmosis

Reverse osmosis (RO) has become a widely utilized treatment process for diverse applications such as medical and laboratory research, desalination, and treatment of industrial wastewater and municipal water/wastewater. Because of its widespread use and technically advanced nature, a variety of quality parameters should be monitored by those treatment operators who utilize it.

Why Aeration Is Central To Sewage Treatment

Take a look at the reasons why sewage needs to be treated and the three main stages of doing so; primary, secondary, and tertiary and see where aeration comes in to play.
