In water treatment applications, different types of pumps are selected based on criteria such as:

  • System requirements
  • Flow capacity requirements
  • Discharge pressure requirements
  • Availability of space

The pumps most commonly used in water distribution systems are centrifugal, vertical turbine, and submersible pumps.

1. Centrifugal pumps

“Centrifugal pumps are the most common types of pumps used in water distribution,” says a water industry specialist working for the Woodhams Group. A circular fan or turbine-shaped impeller is mounted on a centrally supported shaft that is rotated by a motor that can be powered by diesel fuel or electricity. When water enters at the center suction a high velocity is imparted by the rotating impeller that circulates the water, throwing it outward.

2. Vertical turbine pumps

Generally used in raw water intakes and at booster stations in a water distribution system. The water is channeled through a cross-sectional, uniform area. A central impeller is situated along the axis with blades shaped in a way that allows the water to flow in a radial direction.

3. Submersible pumps

Submersible pumps are used mostly to pump groundwater from wells and are placed below the water level. It is a multi-stage centrifugal pump with impellers mounted on a vertical shaft. An electric motor that drives the pump and constructed for use in submerged operations is positioned adjacent to the pump.

Water Treatment

Pumping pure water is very different from pumping waste water. Wastewater often contains contaminants in the form of long fibres or other abrasive solids. A lot of aggressive chemicals are used in water treatment operations. Water treatment plants usually make use of continuous flow operations with points in the process for additional treatments such as filtration, dosing of chemicals, disposal of treated sludge, sedimentation, and storage. Some water treatment operations have periodic processes that run only once a day or once a week.

In a professional waste treatment plant a number of processes are involved including:

  • Physical – filtration and flotation
  • Chemical – chlorination, and coagulation
  • Biological – aerobic and activated sludge processes.
  • A combination of all three

Chemical Dosing Pumps

These are positive displacement pumps used for feeding chemicals into the water supply system at various stages of the treatment process. They are suitable for handling fluids with varying viscosities and abrasive fluids such as viscous liquids and acids and for applications that require high pressure. There are two types:

1. Reciprocating pumps

A piston moving back and forth in an enclosing cylinder pushes the water into the cylinder with the help of check valves.

2. Rotary pumps

A rotary pump has an impeller in the shape of a screw, gear, or lobe that rotates within an enclosed cylinder, imparting energy to the water.

Industrial Water Pumps

Industrial water pumps are designed for pumping wastewater with high reliability and efficiency through all stages of water treatment. They are suitable for the following applications:

  1. Sludge treatment – pumping and treatment of dewatered, stabilized, thickened, primary, secondary, and tertiary sludge.
  2. Wastewater treatment

Planning your holiday for 2018 and need some inspiration?  This destination guide gives you some ideas of what to explore.   Ranging from the charms of Chile to the glorious Granada and the beaches of Bermuda, our travel experts select the top three destinations to visit during the upcoming months in 2018.

1. Italy

Italy, well known for its stunning architecture, delicious dining experiences and incredible art is one of the most popular destinations for international visitors.

Rome is beautiful, regardless of when you visit or where you go in the city. It is possible to become slightly lost, but this is not necessarily a bad thing because you can find many attractive views during your ramblings.

If you take a moment in Florence, you can enjoy the skyline views from the historical churches including the Duomo. Florence is a paradise for artists and history buffs with the Uffizi Gallery hosts some of the most spectacular pieces from the Italian Renaissance. The Florence City Tour is a must for anyone wanting to get a better understanding of the history of Italy.

2. Chile

If Brazil controlled South American travel in 2016, Chile will be taking over from 2017 onwards. Slowly and methodically, the continent is one of the most overlooked adventure tourism destinations and this is precisely why it was chosen as a destination for last year’s World Travel Awards.

Why? What makes Chile so attractive?

Chile has a geographic land space of 2,650 miles long, but it was never more than 150 miles wide. It is filled with various ecosystems, topographies and biodiversity presenting with 36 national parks, deserts and sub-polar islands. To make all of these islands and fjords accessible, it is necessary for Chile to have roads, footpaths and other infrastructure.

The capital of Chile is filled with many new boutique hotels including Luciano K and Magnolia. It is also known for the upcoming fine dining, including the four restaurants within the influential San Pellegrino Top 50 ranking for 2016.

The wine tourism is a strong drawing factor for Chile and is arguably one of the most developed areas in the country. The well known Napa Valley has opened up to visitors with various hotels, including the new boutique hotel at Casa Bouchon.

With the urban pleasures organized, it is time to deal with the extreme features of Chile. The Atacama Desert in North Chile is approaching tourism by allowing for hot-air balloon flights over the salt lakes. Patagonia takes escapists off on a drive along the Aysen’s Southern Highway. The Parque Patagonia is a boutique hotel in the area and is one of the newest sites in this least overcrowded region.

3. Borneo, Malaysia

Borneo is one incredibly mysterious country where things that go bump in the night will usually be creatures that are both rare and exotic. The rainforests in Borneo are drenched in mist, the mountains are craggy, the wide rivers are winding and the times that await you here are relaxing.

A large number of small business rely on technology to manage expenses, increase efficiency, improve performance and grow profitability worldwide.

According to the study 2015 SMB Routes to Market, performed by SMB Group, 29 percent of small business view technology as significantly helping them improve their outcomes.

Business owners are already burdened with all the task required to keep their company going every day – so keeping up with the fast pace of changes in technology can become a daunting task.

Fortunately, we have compiled a list of all the technology category that a small business needs to incorporate in 2017 to succeed.

1. Mobile Is a Must

It’s hard to imagine a technology which has gained more adoption or grown faster than mobile.

In 2016 alone, over six billion people worldwide have used a mobile device. This number is expected to become close to seven billion by the year 2020.

This makes it undeniable that mobile is a must-have technology in 2017. Due to its massive growth, business should use it and incorporate it in at least four ways, apps, website design, payment, and all-in-one device use.

Mobile Apps

In “Mobile App Strategies Boost Revenues for Small Business Owners,” an article by professor Scott Shane, he explains that having a well-tested and well-developed mobile application is an incredibly effective marketing strategy which gets great results. Scott teaches entrepreneurial studies at Case Western Reserve University.

Mobile-Friendly Websites

As more and more people access the internet via mobile, it’s essential that small business have a mobile-friendly website available to their consumers. There are two reasons for that:

1. Search engines such as Bing reward mobile-friendly websites with better ranking.
2. A company without a mobile version of their website could lose business if consumers go for those that do.

Payment Methods

Mobile Payments have been growing in popularity in the form of apps such as Microsoft Wallet, so it can be a good idea to start accepting them as payment. Companies such as Merchant Account Solutions (a partner of Microsoft) have been making mobile card readers an option for people who own small businesses.

2. Marketing Automation Improves Efficiency

With marketing automation software, conducting marketing activities has become a much more efficient task for small businesses, removing the need for dedicated marketing professionals.

The advantages of this type of software include the ability to segment messages, score leads, and set up processes which respond differently based on a customer’s actions.

Automation software also links seamlessly with a lot of CRM platforms, bringing sales and marketing together and providing both with ample understanding of the prospect or customers. External companies such as Rocket CRM solely focus on improving the CRM automation system for medium to small businesses.

CRM platforms like Microsoft Dynamics 365 do a lot of the heavy lifting which would previously have been handled by manual processes.

For businesses, retaining the top talent is a challenge that you must meet head-on. With this in mind, how do you go about it? Do you use bonuses, benefits, and perks as your only incentives? Do you take into consideration the impact of your business premises?

While bonuses, perks, and benefits are critical in retaining your best talent, delve further into your staff’s needs and you will realize there are many other things that contribute to your staff’s wellbeing. Chief among them is your building.

“In a competitive business environment, providing your workers with a conducive working environment is critical,” tells us employee retention expert at GBS Corporate Training. Herein, we will explore how your building supports your effort in creating a satisfactory workplace environment.

#1. Appreciate Your Staff

Appreciating your staff member is important, as every business owner will reckon. However, the appreciation should go beyond the bonus packages that you give your staff or the spangly company Christmas events. You need to ensure that the building your staff works in is comfortable, clean, and clutter-free. Taking steps to ensure that workers work in a healthy environment is the epitome of appreciation.

As such, business owner should invest in the most effective and efficient air-conditioning system that meets their needs. Over and above this, business owners should also ensure the air-conditioner is well-maintained. Doing this goes a long way in mitigating sick building syndrome from occurring.

#2. Meet Your Worker’s Need to Extract Maximum Productivity

If you have heard your staff members complaining that “it is too hot/cold to work” you should be concerned. Such sentiments mean that they are not putting their best foot forward in their work. To correct this, you should start by ensuring that they have a comfortable working atmosphere constantly.

#3. Keep Communication Open

Open communication among staff members is a fundamental ingredient for a successful business as well as a happy workforce. Therefore, it is important that staff members at all levels are able to express their views and be heard. The building acoustics influence the effectiveness of communication. In fact, improving building acoustics will improve the accuracy of communication by 67%.

#4. Foster a Culture of Fairness

Excessively confined office spaces tend to create a feeling of workspace ownership. Some people end up feeling more important than others, which is never good for an organization. It is, therefore, important to ensure that all employees feel free working in your offices. Thus maintain an open layout or a flowing layout and utilize meeting rooms. In the end, organizations are less susceptible divisions of any kind.

#5. Achieve a Work / Life Balance

More and more employees are concerned about their work/life balance. This consideration plays a major role in determining your ability to retain your top talent. Luckily, it is flexible and working toward achieving this goal can feature a myriad of solutions. For instance, to improve the health of your workers, you can customize communal spaces to allow … Read more ...

In a construction project, heavy equipment is always present. However, despite that they’re quite useful, they can also be dangerous, especially when you are not using them correctly. That’s why accidents are quite common in the construction site; oftentimes, workers get injured whenever they are using or close to bulky or heavy equipment. To prevent that from happening, follow these construction safety tips around heavy equipment.

Wear Smart PPE

At a construction site, the employees should be encouraged to wear smart PPE, such as safety glasses, gloves, vests, hard hats, and sturdy boots. Additionally, when loading and unloading the equipment at the construction site, it should be done on level ground– this would eliminate the risks of rollovers when getting the items on or off the trailer or truck.

Constant Communication Is a Must

With the advancements in technology and the help of IoT, communication has been more comfortable. For that reason, it’s imperative for project managers to ensure that there’s constant communication with the people on the job site. A two-way radio is the best form of communication, but there are other smart devices that you can also use for this purpose.

Know Your Environment

When operating heavy machinery, it’s very important to stay alert at all times and be mindful of your surroundings. Make sure that the overhead power lines are de-energized, but if it’s not possible, then create barriers to prevent making direct contact with them. For this purpose, smart traffic cones can be quite useful as it can detect unusual activities which would automatically alert those who are in charge.

In case you are digging, check if all the underground utilities, like the gas, sewer, electrical, and water have been thoroughly reviewed and adequately marked. This would assure you that there isn’t any damage that might intervene with the project.

Aside from that, workers should be prohibited from going to locations where heavy equipment are being used. Likewise, operators should know the swing radius, especially when tackling a project in cramped spaces to avoid hitting bystanders, workers, or other equipment nearby.

Check Equipment Regularly

You have to keep in mind that each machine contains thousands of moving parts or more that have to be regularly checked to ensure that it’s in excellent condition. It is essential to inspect the machinery, especially heavy equipment to avoid accidents and injuries. However, if IoT technology is already being practiced within the job site, most of this machinery are probably embedded with sensors that send signals whenever it’s not functioning correctly.

Only Use the Equipment for Its Main Purpose

Each construction equipment or machinery is made to perform specific tasks. For instance, excavators are not cranes, and wheel loaders aren’t designed to carry construction workers in the bucket and function as an aerial lift. What we are trying to say is that you should be using the right kind of equipment when performing tasks, and make sure that you are using it based on the manufacturer’s instructions. That means … Read more ...
