Progressive Cavity and Centrifugal Wastewater Pumps

Wastewater

Shanley Pump and Equipment, Inc. has been serving the wastewater pumping community for over three decades. Our lines of specialized wastewater pumping solutions for both RAS and TWAS applications are designed to fit any budget and necessity in the municipal, the commercial and private wastewater pumping markets. All of our wastewater pumps are available in a variety of sizes, flow rates, materials and configurations to make installation easy and provide a long service life under proper conditions.

Physically, wastewater is usually characterized by a gray color, musty odour, a solids content of about 0.1%, and a 99.9% water content. The solids can be suspended (about 30%) as well as dissolved (about 70%). Wastewater can come from both industrial and domestic applications as well as rain runoff from streets and sewers.

Chemically, wastewater is composed of organic and inorganic compounds as well as various gases. Organic components may consist of carbohydrates, proteins, fats and greases, surfactants, oils, pesticides, phenols, etc.. Inorganic components may consist of heavy metals, nitrogen, phosphorus, pH, sulphur, chlorides, alkalinity, toxic compounds, etc.. All of these waste compounds can have a tremendous wearing and effect on your pumps and equipment which is why it is so important to have the right pump for the correct situation.

RAS and TWAS Pumps

At every stage of our work, from research and development to design, production and testing, we use both newly discovered and traditional pump technologies and the most modern equipment available to ensure that every installation meets the highest possible standards of efficiency and reliability. Using conventional or special materials, we assemble and test pumps at our facility or at yours for specific needs and conditions that are specialized to your needs.

Municipal Wastewater Supply Pumps

Water Clarity Example

Municipal water use is directly related to the quantity of water withdrawn by populations in cities, towns, housing estates, domestic and public service enterprises. The public supply also includes water for industry that provides directly for the needs of urban populations and this demand also consumes high quality water from the city water supply system. In many cities, a considerable quantity of water is used in market gardening and for watering vegetable gardens and domestic garden plots.

The volume of public water use depends on the size of an urban population and the services and utilities provided, such as the extent of pipe networks for supply and sewerage, or centralized hot-water supply where available. Also, much depends on climate conditions. In many large cities, present water withdrawal amounts to over 150 gallons per day per person which looks to only increase more in the future. Efficiency in wastewater treatment is becoming a crucial step to future planning in cities.

A greater part of the water that has been withdrawn from the urban water supply system is returned to the hydrological system after use (purified or not) as waste water, if urban sewerage networks operate effectively. The major sources of actual consumption consist of water lost through evaporation from leaking supply and sewerage pipes, from watering plants and recreational areas, washing streets, and garden plots.

The modern trend in the development of public water supply all over the world is the construction in both large and small cities of effective centralized water supply and sewerage systems, connecting together an even greater number of buildings and populated areas. By doing so, these cities and towns will need to ensure that their municipal pumping stations are operating at peak efficiency.

Municipal Waste Pumps

In general industry where water run-off in the plant may drain to a central sump and is then pumped out to a collection tank, the solids in the water usually represent plant debris and tend to be quite small.

As they also represent a low percentage of the total volume, the slurry can usually be handled by a conventional centrifugal sump pump. The specific pump design in these services can be quite varied, but the traditional vertical submerged suction sump pump and the submersible pump are both widely used.

Shanley Pump and Equipment carries many models of pumps for the wastewater industry including progressive cavity wastewater pumps and centrifugal pumps for wastewater applications from manufacturers like Liberty Process Equipment, EDUR, OSNA and more.

If you have any questions about our services, please feel free to call us or send us an email! We look forward to hearing from you.
