What is the Pump Suction Pipe & Why Does it Matter?

The suction pipe is one of the most underlooked components of a pump system. However, it plays a crucial role in ensuring that the overall pump system functions efficiently without any glitches. Here, in today’s post, we take a closer look at the role of the pump suction pipe. What is the Suction Pipe? As the name implies, the suction line of the pump system is a pipe that transports fluids from the source to the pump. The Role of Pump Suction Pipe

Suction Pipe Length

Though, it’s a small component in the overall pump system the suction pipe plays several crucial roles. They are:

It ensures that the displaced liquid/fluid is transported
It plays a role in the overall friction loss of the system.

As you can see, the suction pipe plays a crucial role in determining the overall efficiency of the system. A lengthy or an undersized suction pipe can cause negative or positive effects to the system. How does the Suction Pipe affect Friction Loss in the System? While installing the pump system, you have to consider the friction losses in the system. While calculating the power required for moving the liquid/fluid from point A to point B, you must also consider the resistance due to friction, apart from distance. To ensure that you calculate the overall power of the system accurately, you need to consider the friction loss of the suction line. Very often, this is forgotten. By not including the friction loss of the system into consideration, you are most likely to purchase the wrong equipment that is not up to the task. This is a costly mistake, as you end up overhauling the entire system in the near future. Make sure that you design the suction line before you purchase your pump system so that you choose the right equipment for the task. Why Short Suction Lines Work Better?

Short Suction Lines

Irrespective of the type of liquid you are pumping and the pumping system you use, your number one goal is the efficiency of the overall pumping system. The number one question you have to address while designing the pumping system is – how do you displace a particular volume of liquid/fluid from one point to another, within a particular time, using as little energy as possible? A short suction line is part of the solution. Here are the top advantages of having a short suction line:

Improvement in Overall Energy Efficiency

The lesser energy you consume, the lower is the strain caused on the pump components. Additionally, low energy reduces the cost of operating the pump. The longer is the suction line, the more energy you require to move the fluid/liquid from the source to the diaphragm/impeller and then onward to the discharge pipe. The general rule of thumb here is – more energy is required for moving the fluid across a longer distance. Additionally, the friction loss in the suction pipeline also increases the energy consumed. The shorter the suction pipeline, shorter is the distance travelled by the dispatched fluid and lesser is the friction loss, thereby reducing the overall energy consumption.

Elimination of Cavitation

Another major issued that impacts pump durability and maintenance is cavitation. Cavitation occurs when pockets of vapour or air are built up in the displaced fluid due to changes in pressure. These tiny air bubbles then explode, which causes shockwaves. The shockwaves cause damage to the surrounding parts of the pump system, which includes the impeller. With a short suction pipeline, it reduces the chances of cavitation. You can check out our blog post that details methods on how to avoid cavitation here. Altering Suction Pipe Length Impacts the Overall Efficiency Decreasing or increasing the length of the suction pipe, along with altering its design can have a huge impact on the overall efficiency of the pump, thereby increasing/decreasing its longevity.

Here’s a quick introduction to the working of a ZLD system. What is a Zero Liquid Discharge System? As the name implies, the ZLD reduces the wastewater generated by an industrial plant. It can be broadly defined as a process that allows maximum recovery of water from a wastewater source. Without ZLD, the wastewater will be discharged into the environment or below ground. ZLD reduces the amount of wastewater discharged by reusing it beneficially. Zero Liquid Discharge can happen in many ways. There isn’t one solution that fits all. A ZLD system is highly site-specific. What works for one industrial plant may not be the best solution for another. Choosing the right ZLD system for your plant depends on several factors like wastewater composition, operating costs, the volume of the wastewater generated, the streams of wastewater to be treated, footprint availability and more. The size and complexity of the ZLD system depend on the nature and volume of the wastewater to be treated and other factors. It can include membrane processes, stand-alone thermal/evaporative processes and/or hybrid systems. How Does Zero Liquid Discharge Work? The ZLD is a wastewater treatment process that purifies and recycles wastewater. This system aims to leave zero discharges at the end of the water treatment cycle. It’s an advanced wastewater treatment method that uses several innovative processes like reverse osmosis, ultrafiltration, fractional electrode-ionization, and evaporation/crystallization. While the actual ZLD system varies from one application to another, a standard ZLD process generally consists of the following steps: Step 1: Pre-treatment and Conditioning Pre-treatment involves removing simple things from the wastewater stream by filtering or precipitation. It also conditions the water and reduces the number of suspended solids in it. Generally, the pre-treatment unit makes uses of a clarifier/reactor to precipitate hard metals, silica and other dissolved components in wastewater. Step 2: Coagulation Sometimes, caustic soda is added in this step for coagulation. This is a technique in which various chemicals are added to the reaction tank to remove contaminants, and other bulk suspended solids from the water. Step 3: Flocculation Once coagulation is over, the treated water is passed into a flocculation chamber. Here, the coagulated particles are stirred with long-chain polymers creating visible particles that look like snowflakes. Step 4: Sedimentation The treated water then enters the sedimentation stage. This consists of a gravity settler that is a large circular tank. The flocculated material and the water flow into this tank, to undergo a slow settling process. The water rises to the top and overflows the perimeter of the clarifier allowing solids to settle at the bottom of the clarifier. This forms a sludge blanket at the bottom. The solids are then passed into a tube, and the sludge is passed into a sludge handler. Step 5: Sludge Handler The sludge handler begins the dewatering process. Depending on the composition of the wastewater, additional chemicals may be added at this stage to reduce the quantity of silica and other materials in the water. Step 6: Ultra-Filtration Ultra-filters can be used in place of gravity sand filters. Fine membranes that filter contaminants from water replace the clarification stage completely. Step 7: Concentration The concentration of the wastewater can be done using any one of the following reverse osmosis membranes, electrodialysis, or brine concentrators. All three methods have varying requirements and the ideal method for concentration is dependent on the application type. Sometimes, two or more concentration methods can be used together to achieve the desired effect. At the end of the concentration stage, you can reclaim up to 60 to 80% of the water. Step 8: Evaporation/Crystallisation The next step involves generating a solid from the water using thermal processes like evaporation. In evaporation, the water is completely evaporated, leaving behind solid wastes. The evaporated water is then recollected and made available for reuse. Sometimes de-aeration is done at this stage to release dissolved carbon-di-oxide, oxygen, and other non-condensible gases. The leftover waste from the evaporator is then sent to a crystalliser. The solids are filtered out as crystals, and the water is made available for reuse. The treated water is then stored in a holding tank and is reused as required. The ZLD system makes water safe for reuse. The solids generated from the process are converted into a solid cake, which either can be reused or goes to a landfill.

How to Select the Right Pumps for your Wastewater Systems – A Comprehensive Guide

The Need for Wastewater Pumps Water is one of the most important elements for any industry. Be it paper manufacturing, sugar processing, chemical industries or more, water serves many purposes in the industrial plant. And, this essential element is becoming more and more scarce. This means, industries have to look for ways to reuse water, thereby reducing the burden on the environment. Once water has served its use, it needs to be collected and dispatched to the wastewater treatment plant. A wastewater treatment plant is one that treats used water and makes it suitable for other applications. In the treatment plant, wastewater flows through the system. Sometimes, wastewater has to be moved opposite to gravity. In such instances, you require a pumping station and pumps to create a stable and smooth flow of the wastewater throughout the treatment plant. The Unique Challenges faced by Wastewater Pumps Wastewater is trickier to transport. This is because it has plenty of rags, organic solids, debris and other waste water immersed in it. Also, it’s essential that the pumps you use for displacing wastewater are highly reliable, to prevent overflows and spills. In the unfortunate case that a spill occurs, it could lead to environmental pollution, thereby attracting huge fines from the local authorities. This is why; you need to spend considerable time picking the right state-of-the-art pumps and wastewater pumping stations for your industry. No worries, here at Sintech, we help you find the right wastewater pumps that meet your specific requirements. Let’s get started. What to look for in a Wastewater Pump? Here’s a quick look at the factors you have to consider while choosing a wastewater pump.

Minimum energy use
Maximum pumping reliability
Aesthetically pleasing design (it has to be invisible)
Features that deal with odour (mostly hydrogen sulphide)
Intelligent control systems
The pumps must suit even challenging pump station layouts

Types of Wastewater Pumps There are several kinds of wastewater pumps. The common ones are:

Single-stage dry well pumps. These are known as conventional wastewater pumps and are available in a vertical or horizontal configuration.
Single-stage, solids handling, wet-well submersible pumps. Some particular types of submersible pumps are suited for both dry and wet well installations.
Single-stage or two-staged solids handling pumps with vertical turbines.

When choosing the right type of wastewater pumps, you have to consider several factors like life-cycle economic costs, applicability, and more. Quick Description of the Different Types of Pumps

Conventional Wastewater Pumps

These are also known as non-clog, solids handling or dry-well pumps. Their main purpose is to pump liquids that contain soft solids and other stringy material. They don’t require frequent servicing and cleaning and operate without plugging. They can either be installed with horizontal or vertical mounting. Vertically mounted pumps use a motor on the pump frame or a life shaft.

Submersible Pumps

These are non-clog pumps that are immersed in the wastewater for operation. They come equipped with powerful motors. They are installed directly in wet well. This means wastewater pumping stations that use submersible pumps don’t require a dry well. The pumping system construction above the ground is minimal. All that’s visible above surface is a concrete slab and a small housing construction for the control centre. Conventional Vs Submersible Pumps – Which one to Choose? Both these types of wastewater pumps have pros and cons. here’s a look at the differences between them. Submersible pumps don’t require a dry well. This means the construction and installation costs of this type of pump is way lesser when compared to conventional pumps. On the flipside, submersible pumps are not readily available for service and inspection and don’t give much warning of any impending problems. This means the cost of service and maintenance are higherwhen compared to conventional pumps. Also, if any repair occurs it could lead to lengthy downtimes. When it comes to installing submersible pumps in wet-wells, it’s usually set up with a fixed discharging pipe that is supported by a tripod placed on the wet well floor. In such an installation, the wet well has to be drained during inspection, maintenance or service. Another alternative method of installing submersible pumps is the new pull-up design. Here, the discharge pipes are connected to a specially designed elbow that’s permanently fixed to the wet well floor. The pump discharge and the elbow come with a self-locking coupling. This set up, comes with a mounting bracket that moves up and down on rails. The pump can be raised or lowered into the wet well with the help of cables and cranes. The result, inspection personnel need not enter the wet-well and there’s no need to drain it during service. A few types of wastewater pumps that have submersible motors require continuous immersion in water during operation. They run only for short periods when exposed to air. Other advanced submersible pumps come with motors that provide internal cooling and can be operated continuously even at full loads, without immersion. You can also find internally cooled pumps for dry-well installations too. These pumps are highly resistant to damage even if the dry well gets accidentally flooded. The minor drawback with these types of pumps is that they come with higher initial costs. The latest pump in the non-clog pump world is the solids-handling, vertical turbine pumps. As the name implies, these pumps have the best of both vertical turbines and solids-handling. It’s installed directly on the top of the wet well and there’s no need for a dry well. It uses an angle gear or motor that is placed on top of the pump discharge head. This pump uses standard drivers and the drivers are easily accessible during maintenance or service. The discharge connections and the symmetrical bowl design can be mounted either below or above ground. Though this pump is a bit expensive, it reduces the need for a pumping station and dry well, thereby keeping the overall costs down.
