Blade Size Does Matter When Choosing Submersible Mixers

Choosing the right machinery for your business can be a challenge, especially if you are trying to reduce costs without affecting the quality, productivity, and output of your organization. Submersible mixers are devices that many water, sewage, environmental, and agricultural plants use to treat and keep solids and liquids separated. Many organizations also use these devices during various treatment stages, including bio phosphorus elimination, solid suspension, thickening, denitrification, and nitrification. Since there are several kinds of devices to choose from, one needs to consider what their actual productivity needs are.

Small Blade High Speed Mixers

Small blade mixers have a direct drive motor that produces turbulent flows at very high speeds. This makes it far easier for them to mix and thicken solutions at a faster rate. The mixing blades are smaller, reducing the amount of liquid that is processed. Smaller blade devices tend to last longer and are more durable than large blade mixing units. Many mixers come with additional features that offer extra benefits. These benefits include increased leak protection, self- cleaning capabilities, more reliability, simple installation, and less energy consumption to reduce overall energy costs.

Large Blade Mixers

Although large blade submersible mixers are able to process larger batches, they do not mix as fast as their smaller blade counterparts. Even though one’s goal may be to treat large quantities of liquid at faster rates, one has to consider the overall benefits of using a large blade mixer. Large blade mixers are actually more efficient and cost effective for businesses. They require far less energy to run and reduce operating expenses significantly. These units also come with many of the same benefits that small blade mixers have, such as easier maintenance, easy operations, and leak protection.

Submersible mixers can be used in a wide variety of industrial and treatment applications. Contact us to improve the quality and efficiency of your organization. We have mixers that can handle all of your agitating, mixing, and suspension needs.

Choosing Check Valves: What You Need to Know

Many may think that check valves are little more than on-off switches to control water flow. Yet as the many industrial applications for these valves have grown, basic valve design and makeup has evolved to keep up with these changes. Today, there really is no such thing as “one-size-fits-all” valve. Choosing the right valve requires a fair amount of research into the job that it will be expected to assist with.

Matching Performance to Need

The first step in knowing which of the many check valves on the market is right for you is understanding if a certain valve’s characteristics will meet its service requirements. That requires an in-depth knowledge of every phase of the job needing to be done, including:

·         Pressures

·         Temperatures

·         Volume of flow

·         Corrosive elements

These factors should outweigh whatever considerations come with a valve’s purchase price, as well as the costs associated with installing and maintaining it.

Valve Composition

Or course, in order to truly understand how a valve will hold up under pressure, you need to think of what the valve is made of. Different metals and alloys deliver various levels of performance. Below is a list of different materials and what conditions they can endure:

·         Iron: Iron valves are typically made in three grades: Cast iron for smaller valves, ferrosteel for valves of medium thickness, and high tensile iron for large size castings. Each type can thrive in temperatures up to 450°F.

·         Bronze: Steam bronze is typically used for valves asked to endure a similar temperature range as iron. For temperatures above that, special bronze castings are available.

·         Steel: Steel is the metal of choice for those jobs where working conditions may be too severe for either bronze or iron. Both steel and stainless steel have been shown to stand up remarkably to the effects of piping strain, shock, temperature fluctuations, oxidation, and galling erosion.

Types of Wastewater Pumps | Purestream Inc.

by Administrator5. January 2014 21:08

When it comes to wastewater pumps, there are many different types available for every type of situation. Understanding which pump to use for your application is important, both with reducing costs and maintaining longevity. Let's take a look at some of the different types of wastewater pumps.

Centrifugal Pumps

"Centrifugal pump" is a general name for a wastewater pump with one or more impellers. There are many different kinds available out there, for use with many types of application. Centrifugal pumps are used to move wastewater by the converting kinetic energy to hydrodynamic energy. It's powered by an electric motor or engine. They're the most popular type of pumps used today because of the number of uses, which include fire pumps, grinder pumps, end suction pumps and magnetic drive pumps.

Many different liquids can be processed with centrifugal pumps. They have a high flow rate and can handle many different types of liquids and clean water or wastewaster. The liquid processed shouldn't contain air vapor.

Drum Pumps

Drum pumps were made to eliminate having to dump the liquid inside the pump when it got full. Drums are made so that all you have to do is insert the tube into the pump, turn it on and the wastewater is drawn out steadily. Drums are good for reducing the chance of spillage. Drum pumps are commonly used in chemical plants and food processor plants.

Grinder Pumps

Grinder pumps are submersible pumps used to grind wastewater solids. They are normally used for in groups of housing or a commercial sewage setting, such as for a school. Grasping the idea of grinder pumps is simple: The pump is used to grind the solids up, send it out, and pump it to a large nearby sewage collection site. It is then combined with the sewage from other buildings and homes and pumped to the sewage treatment center and onto a lift station.

We'll go over even more types of pumps (along with their uses) in our next blog post. Stay tuned.


What Is A Comminutor | Purestream Inc.

by Administrator30. October 2013 11:44

A comminutor is a machine that is used in wastewater treatment plants to cut up wastewater solids. In other words, a comminutor is a size reduction device, doing so by grinding up the wastewater solids.

Large, stringy wastewater solids can plug pump impellers and can damage belt filter presses and centrifuges. But a comminutor minimizes damage and reduces downtime, and therefore provides cost benefits.

Comminution technology is fairly new. You won't find the word ‘comminutor’ in many dictionaries. We think it'll be added in soon, though - comminutor technology is increasingly popular today as more and more municipal councils (and other bodies) that deal with solid waste treatment receive higher quantities as populations increase.

The comminution technology is evolving rapidly, and this has led to an exciting race between comminutor manufacturers. As an example, many of today’s comminutors use twin shaft grinding with screw screening systems and high flow capabilities.

Comminutors, which are also known as macerators and grinders in the industry, were first used in the 50s (drum-type comminutors). After drum type comminutors came straight-through comminutors, followed by in-line comminutors/grinders, dual shaft comminutors (grinders), and then cutter cartridge enhanced twin shaft comminutors. Comminutors get better with each passing decade.

Most comminutors use counter-rotating sets of inter-meshing cutters to shred and cut solids into fine particles. The greatest drawback of such systems is that very little open area is left for fluids to pass through, thanks to the banks of intermeshing cutters. This problem is solved by cutter cartridges in enhanced twin shaft comminutors. A cartridge is a one-piece solid element, as opposed to multiple individual spacer disks and cutters. The use of cartridges has led to an increase in cutter strength.

The components that make up comminutors include:

  • Housing
  • Right-angle gear motor
  • Double-sealed shielded bearings
  • Inlet trough
  • Drive shaft 
  • Rotating cutting bar/s
  • Stationary cutter comb 

The most commonly used material for the cutter comb and cutter bars is A2 chromecarbon tool steel. Comminutors are made for outdoor use.

How to Choose the Right Type of Comminutor

You shouldn't go for the first comminutor you come across. You should consider the type of comminutor, the expertise of the manufacturer, if the unit is ruggedly constructed, the upstream head capacity, ease of installation and maintenance, and your particular circumstances and preferences.
