White Papers for Water and Wastewater Treatment and Management

Since 2001, the United States Geological Survey (USGS) has collected water-resources data in all 50 states and beyond. The organization has studied groundwater, surface water, water quality and water use through initiatives such as the National Streamflow Information Program (NSIP), which used...

When a check valve breaks or malfunctions, it may cause an entire system to break down. A new, high-quality check valve is needed—and it’s needed immediately. While a company may have a backup valve they can use in the meantime, it’s still necessary to get the replacement quickly. Check-All...

To make the products safe for water distribution there must be protective barrier material, joining, and sealing materials. These materials will ensure that the water remains free from any contaminates that may be present on or in the metal, paint, gaskets, lubricants, etc. NSF/ANSI has...

Microfiltration/Ultrafiltration MF/UF systems are used to remove suspended solids (TSS) and high molecular solutes, while water and low molecular weight solutes pass through. Membranes are defined by the molecular weight cut-off (MWCO). Nanofiltration NF is very similar to that of RO, with...

Provide Continuous Monitoring and Reduce Maintenance Costs in Sewage Lift Stations. The Level Transmitter is a small but vital component in a Sewage Lift or Pump Station to maintain system integrity and avoid unwanted spillage.

Key Differences Between Data Logging and Data Acquisition What is the difference between a Data Logger vs DAQ System? A data logger is a type of data acquisition system, but a data acquisition system is not necessarily a datalogger. There are several key functional differences in how the market...

Like anything else, there are both cheap and good quality ultrasonic sensors out there. Besides good manufacturing, one of the major differences between a good sensor and everything else is programmability. While non-configurable sensors might seem like a bargain, the advantages of programmable...

If you need help determining which type of cooling system is correct for your application.

ChlorTainer is a high-pressure containment vessel into which a 1-Ton or 150-lb chlorine gas cylinder is processed. If the cylinder should leak, chlorine gas is contained within the vessel and processed at a normal rate. All of the chlorine gas is used, and no hazardous waste is generated.The...

There are many components that are involved to make a COMPLETE Wastewater System. Global Treat provides all items in the drawing that are marked in RED.

PCI Gases , a California-based manufacturer of oxygen generators used in water and wastewater applications, conducted an energy study on behalf of a Southern California municipality. This study compared life cycle costs of two technologies—Vacuum Swing Adsorption (VSA) and Pressure Swing...

Acrison Equipment helps GE Plastics meet their aggressive requirements for increased production and stringent end product quality requirements.

Proper chemical storage is critical to minimizing risk in a laboratory or industrial setting. The safe storage of hazardous substances is an essential part of any environmental, health, and safety program for your lab. To minimize liability and reduce the risk of an accident occurring it is...

Water filtration has been present throughout recorded human history. There are records of water filtration as far back as 2000 BC. Human bodies consist of 70% water and therefore need water — potable water — to sustain them. Historically, civilizations were constructed around bodies of water,...

How do you meet your dissolved copper discharge limit if it is 1.6 ppb, 3.1 ppb or 6.1 ppb? What is the cost to achieve these limits? Which treatment is cost effective? Is deionization, Reverse Osmosis or chemical precipitation the best alternative to low level of dissolved copper in a...

If an application calls for the accurate fluid sensing of liquid level, pressure or flow, Gems Sensors & Controls can help. Their extensive fluid sensing portfolio has evolved from nearly 60 years of field-proven successes in a variety of markets. Common customer fluid sensing challenges can...

This white paper provides general guidelines and highlights key considerations when choosing a control system platform (DCS or PLC).

Rice University is located within the Harris Gully watershed, which covers a drainage area of approximately 5 square miles, consisting mostly of fully‐developed residential and light commercial land use. The area is also home to Hermann Park and Texas Medical Center, the largest medical center...

In 2013, Pure Aqua successfully supplied, a demin water system to PDVSA (Venezuelan government). The water is used for boiler feed, a new power plant currently being constructed. Pure Aqua provided packaged/skidded equipment consisting of Multi-Media Filters, Reverse Osmosis Unit and...

Concern about ammonia emissions in the air and the water continues to grow, both officially and unofficially. As U.S. Environmental Protection Agency (EPA) moves to further reduce ammonia concentrations in surface waters, common water treatment methods transform what had been a water...

Installaton of BDP Industries Model 3DP Belt Press has significantly lowered the cost of dewatering the WWTP waste sludge and the energy costs to dry the sludge in their drier.

This article takes an in-depth look at the advantages and disadvantages of steam and hot water for jacketed heating, and compares indirect and direct steam injection systems for making hot water.

Duplex and Monel are expensive materials to use for seawater strainers, and SS316L does not last forever. Acme has introduced automatic strainers with vessels fabricated in FRP and Monel or Duplex in
