Enhanced Bio-Remediation of Wastewater

Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

Kansas Facility Finds Fast, Reliable Fix to Cavitation Damage

The Hutchinson (Kansas) Water Plant gets its water from 20 wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back ...

Controlling the Flow Capacity of a Metering Pump

Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length ...

Detailed dynamic pumping energy models for optimization and control of wastewater applications

Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this unbalance in the coupled submodels. The model is ...

Fuzzy maximum power extraction control for a photovoltaic water pumping system

AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

Controlling the addition of Chlorine into a Process

There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...

Principles of Solids Control

Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due to a growing awareness that drilling fluid maintenance and disposal can become exponential problems as they are both harmful to the environment and ...

Industrial Pump Inspection

An industrial pump service and remanufacturing company had two goals in mind when they went shopping for a borescope. First, the scope had to be easy to use and portable enough to take on service calls. Second, it had to have four-way camera articulation in order to steer navigate the pipes and small through-holes that are commonly found in industrial pump applications. They found exactly what ...

Leakage control of multi-source water distribution system by network partition and optimal pump schedule in China

The main aim of an optimal schedule of conventional multi-source water distribution system is to reduce the energy consumption rather than minimizing the network leakage. This research is on the premise of meeting water demand, pressure and water quality considering the states of valve opening and closing, the states of pump opening and closing, and the pump speed as solution space.
