Your Guide to Sewage Treatment Plants!

When you’re inclined towards knowing about sewage pumps, you should dig deeper and get to know about sewage treatment plants as well. If it had to be said in simple terms, a sewage treatment plant refers to a below-ground vessel that helps in treating the incoming effluent to a quality that is environmentally acceptable. Further, the given treated water can be legally discharged in ground soak away following applicable consents or exemptions or to flowing surface waters.

How do sewage treatment plants work?

Almost all the sewage treatment plants are known to use the same 3 stage principle in order to treat the influent; primary settlement then biological treatment and then final settlement.Have a look at these stages:

Stage 1 – At this stage, the influent enters the primary settlement chamber. This is where the solids sink to the bottom of the chamber. Here, they begin to form a sludge. This sludge is periodically removed with the help of a tanker.

Stage 2 – At this stage, the remaining liquid would move forward to the biological treatment zone. Now, this biozone is where the air containing oxygen is introduced to the liquid. This is done for encouraging the growth of aerobic bacteria. These bacteria are found naturally in the sewage. It is done by allowing the bacteria to breath. In most treatment plants, the use of media in the biozone is also seen. This helps in providing a huge surface area for the same bacteria, for it to cling to as well as grow.

Stage 3 – Finally, at the third stage, the treated effluent starts moving into the final settlement chamber. This is where the calm will allow the biological material to settle. In such cases, it settles at the bottom for further treatment or periodic removal. Eventually, the remaining settled liquid will start flowing out to the surface waters or the ground soak away.

How to install them?

The user of sewage pumps would always know the importance of a complete range of sewage treatment plants that accommodate the needs as well as wants of a very diverse range of applications or properties.

Touching The Basics Of Water Pumps

Whether you wonder about high head submersible pumps, or want to know more about dewatering pumps, or are simply curious about raw water pumps, you need to know the basics of any water pump.
high head submersible pumps

Many times, even knowing the basics doesn’t cut it as it is imperative to actually remember them. So, whether you are a person who is totally unaware of the basics of a water pump, or a person who has simply forgotten about some of them, this blog will benefit you. 

HOW DO WATER PUMPS WORK?

The pumps function through creating a vacuum. In this vacuum, the ambient air pressure does the job of forcing the liquid. It is imperative to know that all the pumps work by creating low-pressure areas. In a centrifugal pump, centrifugal force accelerates the water to the outside of the impeller creating low pressure at the center or the eye of the impeller. When it comes to reciprocating pumps, the upstroke of the plunger or piston plays the role of creating a vacuum. On the other hand, when it comes to in-gear pumps or lobe pumps when the teeth or the lobes mesh and then come apart, the creation of a vacuum takes place. It is the difference in the pressure that leads to creating a suction. As a fact, we know that a liquid under higher pressure moves to an area of lower pressure.

LET’S TALK A LITTLE ABOUT PUMP PERFORMANCES

One thing to know about pumps is that they have strict tolerances as well as precise conditions.  They must operate under these conditions in order to generate the BEP or what’s known as the Best Efficiency Point. Each and every pump possesses a chart that shows the performance curves. They also display how the attainment of the BEP can be achieved. Whether they make high head submersible pumps, dewatering pumps, or any other pump, all manufacturers go for calculating the performance curves with the help of a pressure gauge as well as a flow meter. This is connected to the discharge port in order to find out the optimal configurations of piping, type of head and fluid, etc. It is fortunate that the discharge capacity is possible to be calculated for any head.

SHEDDING LIGHT ON THE BASIC PARTS OF PUMPS
The basics include the casing, fluid displacement device, bearings, the hub, as well as the Seal. 

Apart from these basics, there’s much more to know about pumps.

How To Rightly Choose a Water Pump That Suits Your Needs?

In simple terms, a water pump refers to a mechanical device that does the job of transporting media. This is done by transforming the energy that is being supplied by a motor, into hydraulic energy. When it comes to choosing the right water pump, be it sewage pumps, or dewatering pumps, or any other kind of pumps, there are some things that should be carefully considered. 

water pumps

So, when we look at the first criterion for choosing any water pump, it becomes the type of media that is concerned. The right thing to do is to take into account the technical characteristics of the media. It is because they are the ones that will determine the choice to be made.

Further, to properly dimension the machine as well as to calculate the operating point of the water pump, it is important to know the parameters of the network. They include flow rate, static head, frictional losses, total working head, contamination (solids) in media and more like it.

This blog helps in giving you an overview of a few main types of pumps as well as the situations in which they are generally used.      

Firstly, one needs to determine what media is going to be transferred, this is for avoiding corrosion phenomena and by that also avoiding premature wear of the pump. Therefore, it is highly essential to know the chemical composition of the media that is to be pumped. One needs to determine if the media is chemically neutral or corrosive, this aids in choosing materials that will be compatible with the pumped media

Secondly, one should know the possible presence of solid components, and the viscosity of the media. Knowledge about all the physical properties of the treated fluid allows choosing of ideal technology for given application as well as the ensuring that pump operates trouble free under given conditions.

Remember a general rule, that the more viscous the media at hand, the tougher the flow through the pumping system. However, be careful as the viscosity varies according to different operating conditions.

Thirdly, there are different types of pumps out there. They are:
  • Centrifugal pumps; where the fluid gets sucked by a paddle wheel/ propeller (most common model).
  • Diaphragm pumps; where the fluid is sucked in through the oscillation of a diaphragm.
  • Piston pumps where the fluid is sucked in as well as out by one or more pistons’ reciprocating movement.
  • Peristaltic pumps; where the fluid gets pushed into a pipe that is compressed by rotating rollers.
  • Submersible sewage pumps; where the fluid is pumped by submerging the motor under the liquid.
So, when choosing sewage pumps, or any other pumps like dewatering pumps, make sure to consider these three points before making the final decision.

Did You Know This About Mine Dewatering Pumps? 

When it comes to any kind of pumps, be it dewatering pumps, sewage pumps, or any other kind, it is always best to know what you’re getting into. In this blog, we will be talking about mine dewatering pumps.

submersible pumps

For starters, let’s have a look at what is mine dewatering.

Understanding the process:
In the simplest terms, the process of mine dewatering refers to the act of taking out groundwater from a mine.

Types of mines:

There are various types of mines like coal mines, iron ore mines, etc. But, why is it important for you to know about them? Well, when considering executing the process of mine dewatering, you will need to know about the abrasion of the given liquid to be pumped out. Depending on the mine, the abrasion of the liquid will also vary. Many of your mine dewatering decisions will be based on this consideration.

Pumping challenges faced during mine dewatering:

1. The difference in mines- When we look at different mines, we see how there are two types. One is the close mines, and another is the open mines. The challenge is that for both the mines, there are different safety parameters. According to this, you will have to choose the dewatering pumps that suit your needs.

2. The difference in voltage requirements- Depending on safety parameter voltage requirements are different for different mine sites. Therefore, when it comes to mine dewatering, you have to ensure that the dewatering pumps you chose are compatible to work with given voltage range.

3. The difference in head requirements- Usually, the head of the pumps need to be higher for the successful execution of mine dewatering. Therefore, it’s very important to go for pumps that have proven track record in such typical process.

4. Wear & tear of critical parts- This is the most critical aspect of mines dewatering. If metallurgy of your mines dewatering pumps is not compatible for pumping abrasive liquids, then your mines dewatering pump can become a huge liability & kill the project cost altogether.

How can submersible pumps be useful?
Generally, different types of pumps are deployed for mines dewatering purpose, many a times these are huge horizontal surface mounted pumps. These pumps may have its own benefits but, they may not serve the above stated purpose perfectly.  However, in modern times submersible mines dewatering pumps are evolving as a big boon for mines dewatering. These pumps are not only lightweight & portable, but also come in various sizes & capacities to suit given site conditions. Based on your requirements you can Mix-n-match the ratings / capacities to make these submersible mines dewatering pumps to reach even remote locations of your mines.

The good submersible mines dewatering pumps manufacturer offers variety of options in terms of metallurgy which is suitable for various abrasive liquids to be pumped & their modular design not only aids in interchangeability of spares but also bring down the overall spare’s consumption for users. So, buying a mines dewatering pumps might appear to be an easy thing, but actually a right mines dewatering pumps can make your life easy.

Maintaining Your Submersible Sewage Pumps

When it comes to pumps like submersible sewage pumps, everyone wants to just do their best to maintain them! However, lack of proper source of knowledge usually gets them at a place where it’s tough to execute it. Therefore, this blog has been created in order to help such wishers, to succeed with proper information and ease.
submersible sewage pumps

The submersible sewage pumps are the kind of pumps that are connected with the pump and their motor is submerged under the liquid. They are suitable for various occasions. For making the equipment last longer, one needs to know about the submersible sewage pumps’ techniques of maintenance.

Few of the critical aspects which needs to be looked into:

1. Determining the correct direction of the motor’s rotation:
In case of Submersible Sewage Pumps, direction of rotation of pumps is one important aspect. These days it is generally observed that lack of awareness in these aspects often leads to abnormal working of pump. It is important to ensure that pump is running in right direction, or else it can adversely affect its flow & current consumption often resulting in damage in winding.   

2. Preventing the power supply voltage from an abnormal start:
It is a known fact that the low-voltage power supply line is relatively long. Due to this, the end voltage of the line being too low becomes a common occurrence. In a case where the phase voltage is lower than normal the speed of the motor of the given submersible sewage pump goes down drastically. This results in abnormal heat up of motor or even burning of an winding.

3. Device for leakage maintenance:
A life-saving device helps with leakage maintenance of the submersible sewage pumps. As pump operates underwater, a simple leakage can lead to power loss and could even end up in an electric shock. If this device is installed, it will block the power supply of the submersible pump ensuring safety and preventing leakage when required.

The other things that one should consider are preventing frequent Start & Stops, not letting the submersible sewage pump work in overload condition for a long time, paying attention to normal maintenance by usually checking the motor current, etc. 

Follow these simple techniques and you’ll be good to go!

Basic Pump Facts That One Should Know

Whether it is about raw water pumps or any other pump, one can only be confident about operating them when he or she knows the basic facts about water pumps. Therefore, it is always a better idea to at least skim through these basic facts. For the convenience of those curious ones out there, we have curated a list of such facts in this blog. 
  raw water pumps

Please have a look at the following:

Water pumps don’t suck fluids:
In the world of pumps, this is a very common misunderstanding. People need to realize that there is some energy source other than the water pump itself, that should supply the energy that is required for the fluid to get to the water pump. This is simply because water pumps do not suck fluids. In normal cases, these sources can be atmospheric pressure and/or gravity. In the end, one needs to remember that the fluids don’t have tensile strength. This is the reason why water pumps do not have the capability of reaching out and pulling fluid into the suction.

The realistic suction lift is around 26 feet (maximum):
It’s already been stated in the previous fact, water pumps do not suck fluids. Now, if you’re at sea level, then the atmospheric pressure would be 14.7 pound per square inch absolute (psia).  This simply translates (multiply by 2.31) into around 33.9 feet of absolute head. One might have been able to lift cold water 33 feet if there was no vapor pressure or fluid friction working against the entire system. Unfortunately, in reality, the fluid friction, as well as the negative consequences of vapor pressure, would end up working against you and precluding the fluid lifts of much more than 26 feet.

Almost all of the pump’s problems take place on the suction side:
Unfortunately, there is another very common as well as a pervasive misunderstanding about the working of water pumps. When you imagine any pump system acting as three separate systems, you’ll be able to understand better. Now, imagine them troubleshooting issues out in the field. The pump, the suction system, as well as the system downstream of the pump all working together. Studies show that around 85 percent of the pump issues always occur on the suction side of the pump. Therefore, whenever you are in doubt, its always a great idea to start looking at the suction side for the solution.

Are you New to Pumping Slurry?

If you are one of those who has ever pumped slurry, you would be able to tell and know it in your heart, that it has the capability of being one of the most challenging fluids to be moved. The slurry is a fluid that is abrasive, sometimes corrosive, thick, and it is also known to contain huge amounts of solids within. There is no doubt about the fact that slurry is a fluid that is tough on the slurry pumps

slurry pumps
 
However, if you have a good amount of experience in using slurry pumps, you would also realize that the more you understand about what is going to be pumped, the better your water pump selection is going to be in every case. This decision will help you in decreasing the failures while pumping slurry.
To understand anything further than this, one should have a basic idea of what is slurry.

So, the question is, what is slurry?


Slurry refers to any mixture of fluid, such as water, combined with a pulverized solid. Slurries are known to be used as a convenient way for handling solids in bulk. This can be in mining, foundries, steel processing, and power generation. Generally, slurries tend to behave the same way as vicious as well as thick fluids, that flow under gravity behave.

So, one should be aware that slurries can be divided into two general categories. These are settling and non-settling. The non-settling slurries have very fine particles. They give the illusion of increased apparent viscosity. They have low wearing properties but need careful consideration when selecting the pump. This is because they don’t behave like a normal liquid does.

The settling slurries get formed due to coarse particles. These tend to form an unstable mixture. The flow and power calculations need attention while a pump is being selected. Mostly all slurry applications are made of coarse particles. This is why they have higher wear properties.

There is another very important thing that should be kept in mind. In order to understand slurry pumping, one has to go to certain depths. Not only do you need to be aware of the basics like mentioned above, but you also need to know all about pump selection considerations. 

Even after knowing it all, you need to put it into application. Only after gaining a good amount of experience with slurry pumps, you will be able to practice it successfully.
