The process of water ultrafiltration

The process of purifying water entails different stages before it is channeled to a water filling machine for packaging. One of them includes ultrafiltration where the separation of solutes and suspended solids is done through a semi-permeable membrane through forces like concentration gradient and pressure.  In the modern day, this process is done through an ultrafiltration system that incorporates hollow fiber and other filtration technology. Filtration I many cases involve the use of active carbon filters, quartz sand filters, precision filters, and finally hollow filtration.

In ultrafiltration, contaminants such as bacteria, colloid, rust and other toxic substance that is in raw water are filtered out. However, important elements such as minerals present are normally kept. This ultrafiltration process in normally incorporated in the purification of mineral or spring water companies before a water filling machine packages it for distribution.

During the process ultrafiltration, clean water under pressure flows through the hollow membrane whereas large particles are retained. This process is usually dynamic as separation is accomplished through a flowing state.

There are different kinds of bottled water in the market. These include:

  •    Mineral water
  •   Purified water
  •    Spring water
  •    Seltzer water
  •    Sparkling water

What is mineral water?

Mineral water is essentially water that contains minerals and other dissolved elements like magnesium, calcium, potassium, silica, sodium and some bi-carbonates. These minerals are usually healthy and have no side effects.

As a water bottling plant, you should design and customize to meet the flow rate and the prevailing water condition. As much as it removes large particles, the ultrafiltration process should also remove color, odor and some organism such as bacteria.

The UF membrane is normally configured in such a way that it operates as a molecular sieve to produce mineral water. The ultrafilter is thin, permeable, tough membrane that can retain macromolecules such as colloids as well as pyrogens and micro-organisms. When buying a filtration machine, take into consideration the corrosion, temperature, vibration, and pressure. For instance, if your water has high TDS, then you should go for a fiberglass filter.

Advantages of Ultrafiltration

  •   Ultrafiltration process removes almost all particles including the colloids,pyrogens,  and micro-organisms.
  •    Minerals such as sodium, calcium, magnesium, and potassium remain in the water
  •    It uses the least amount of energy to produce highly purified water
  •    You can incorporate other treatment equipment depending on the nature of your raw water

 

Which one is better? Ultrafiltration, reverse osmosis or nanofiltration

When it comes to water bottling plant, there is a series of processes and machines that are involved. The process starts with purification where raw water is treated to make it drinkable. Then there is ozone generator that sterilizes water to kill the bacteria and other micro-organisms that are harmful to a persons’ health. Finally, the water filling machine packages the mineral or pure water depending on your choice of purification. This article enables you to go through different types of water purification that allows you to make an ideal choice when embarking on the same process.

Ultrafiltration system

Under ultrafiltration, the accuracy of filtration is usually 0.001 to 0.1 microns. This makes it one of the new and accurate technologies of the 21st century. It has membrane separation technology that allows filtration using pressure difference. In this case, suspended solids, iron rust, colloid, sediment, bacteria, and other harmful particles are filtered out. However, vital elements that are important in the human body are usually left out of this process. This also makes ultrafiltration a perfect way of manufacturing mountain spring and mineral water. In ultrafiltration, the recovery rate is normally high at about 95%.

 Nanofiltration

In the nano-filtration process, the accuracy of filtration is normally between the reverse osmosis and ultrafiltration. Compared to reverse osmosis, the desalinization is relatively lower. There is also membrane separation technology in nanofiltration that is usually pressurized and charged. The recovery rate in this process is also low compared to other purification processes. This implies that most of the water, about 35%, is wasted during this process. Nanofiltration is only recommended for generating pure water for industries.

Reverse Osmosis

In the RO process, the accuracy rate is about 0.0001. This is because it uses an ultra-high precision membrane and uses differential pressure technology. In this case, almost all impurities are filtered out including the beneficial minerals present in water. The reverse osmosis membrane only allows water molecules to pass through and nearly 50% of the tap water goes to waste.  This process is ideal for making ultra-pure water for industrial and pharmaceutical usage. In reverse osmosis, electricity and power are needed. The utilization ratio is low and the flow rate, this makes it not ideal for purification of a large amount of drinking water.

Depending on whether you need mineral, pure or spring water, you should choose the processes that best suit you. Also, remember to get the water filling machine that is in line with the water that is a generation from the purification system.

Factors to consider when choosing material for shrink wrapping

Shrink wrapping is an important factor in any production industry. From protection to aesthetic value, this process adds a quantifiable benefit to the industry. In that regard, it is important to choose the best material that is ideal for your product. There are many types of wrapping materials available, but depending on the several factors they vary from each other. From general factors such as the form of transportation, the storage, and nature of delivery, you should choose the one that best suits your preference.

As a producer, you should be aware that the wrapping material will in turn help in reducing the breakage, spoilage, tampering and product returns. Here are some of the things you should consider when choosing your material:

Quality and durability

Before you order a wrapping material, you should be well conversant with the quality and durability of it. You can learn this by testing the samples or getting insights on online platforms. Some producers skip this vital step, and they end up wrapping products with the low-quality material. Materials such as PVC and polyolefin are good for wrapping products. For instances, the polyolefin is good for food products while the PVC for general items.

Cost

The cost of wrapping material also must come into your mind as a producer. Depending on your product you should choose a material that not only has quality properties but is in line with your budget. The cost of wrapping material should not negatively impact the general output of the company. You should also liaise with suppliers who can offer these materials at a discount rate.

Protection

A suitable wrapping material should help in enhancing the security of the product as well as providing tamper evidence. You should choose a material that can provide a safety measure as well as can be used to act as a tamper-evident seal.

Health and environment compliance

Some of the wrapping materials can release a harmful substance to the environment that brings danger to living specifies. As much as you desire a quality wrapping material, the health of workers should also be a priority. Materials such as PVC can be avoided if necessary or good ventilation measures ought to be taken.

The type of shrink wrapping machine

Some shrink wrapping machines are only used with specific materials. Before sourcing your material, ensure that it will work well with your machine to avoid unnecessary losses.

How shrink wrapping machine saves you money?

Regardless of whether you are selling your products online or at the local stores, packaging your product well is very important.
