The potable water treatment for worker at factories and industrial zone

Providing potable drinking water is an important workplace issue especially for workers at factories and industrial zones.  There are a few options when it comes to provide potable water to workers. The water can be distributed in individual bottles, or from a hot/cold water dispenser, or from potable water treatment system. So, which is the best solution?

Nowadays, with new efficient technologies, the potable water treatment system has become the ideal solution for providing drinking water at factories. In this article, we would like to provide useful information about this solution. We hope you can make the right decision for your business after reading.

The importance of potable water treatment for worker at factories and industrial zones

Providing potable water to workers contributes to creating a safe and healthy workplace at factory and industrial zone. Providing quality potable water is not only an enforced law for factories , but it is also a great way to make sure that productivity is at its highest levels. By offering enough drinking water for workers, factory and industrial zone managements improve overall working conditions and quality of work. Moreover, this improves worker morale and increases their loyalty.

How much water should the factory provide each worker per day? Following the decision No. 3733/2002 / QD-BYT of the Minister of Health dated 10 October 2002 on the Issuance and Promulgation of 21 Labor Hygiene Standards, the minimum water amount is 1,5 l per person per shift. If the job requires a lot of physical activity, manual labor, or if it is outside in the elements, a large amount of water will be necessary.

Providing potable water to workers is part in building a safe and healthy workplace

at factory and industrial zone

Therefore, in a factory with a large number of workers, planning on purchasing bottled water to provide to workers is a challenge. The quality water depends on the suppliers that we can not control it. Besides that, the number of empty bottles discharged into the environment will be a major source of environmental pollution.

So, in order to cover all above problems, a factory may look into install a potable water treatment system. A system can help to remove almost the contamination levels in water and provide potable water which is met the standards of the Ministry of Health. Moreover, the systems can be attached to the tap or large water bottle  s that workers can get drinking water easily.

What is potable water treatment

Potable water (or drinking water) is water that is safe enough for drinking and food preparation. Workers can be able to drink the water provided or wash their hands without fear of being poisoned by swallowing something.

Advantages of potable water treatment system

A potable water treatment system can provide safe and healthy water that is fresh and free from contaminants. As factories are often located at industrial zone which are outside the main city area, it is more convenient for factories to have their own potable water treatment system to produce their own drinking water. It also reduces the amount of time needed to order clean drinking water.

Besides that, the potable water treatment system saves investment cost and has low operating cost that can bring long-term benefits for businesses. With convenient and 1-time installed drinking water treatment systems, factories and industrial zones can provide sufficient drinking water for the needs of workers in many years.

It is also easy to install, operate and maintain. The drinking water treatment system can be cleaned with simple steps. So, factory and industrial zone can maintenance easily by themselves. You can easily replace components of the system with reasonable price.

How the potable water treatment at factories and industrial zones works?

Nowadays, there are many drinking water treatment systems for factories and industrial zones. These systems generally work in the following steps :

Step 1: Sediment filtration

Source water, either from a natural or industrial source, will typically pass through a screen as it enters filtration systems. This step is important because it keeps large material out of the water system, which can clog or otherwise disrupt the purification processes.

Step 2: Coagulation/Flocculation

Coagulation and flocculation are used to remove algae, turbidity, color, and other microorganisms. The addition of a chemical coagulant to the water causes the formation of a precipitate, or floc, which entraps these impurities. Iron and aluminum can also be removed under suitable conditions. The floc is separated from the treated water by sedimentation and/or filtration.

Step 3: Water Softeners

That step reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.”

Step 4: Filtration

Filtration is a critical part of the majority of potable water treatment systems.

The water will be pumped through one of many different types of filters, leaving the accumulated floc behind in the filtration media. These filters, which can be made from cloth, crushed black walnut shell (BWS or NSF), sand, or carbon, trap and remove even more particulate as the water passes through them.

For example, UBF series – Ueberall bag filter is an efficient choice for water with high load and big size particles. The chamber is made of stainless steel, well designed with tool-fee maintenance.

Step 5: Disinfection

Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed. The most common chemical disinfectants are ozone, chlorine and, chlorine dioxide. Besides that, the most common physical disinfectants are ultrafiltration (filters with pores of 0.2 micron or less), purification with ultra-violet light (UV), or reverse osmosis (RO).

The filtered water is then pumped into a closed tank where disinfectant chemicals such as ozone or physical such as UV are used to destroy any bacteria or other microorganisms that may have survived in the filtration process.

RO and UV devices are often preferred in factory drinking water treatment systems due to their high efficiency without fear of residual chemical residues and no unpleasant odors.

Examples: UV devices are often installed together with other upstream treatments, such as filtration, to prepare the water for effective disinfection. One of popular UV devices in the world is UEBERALL UV Sterilizer series. It can be installed in the potable water system for industrial water supply and various industries.

All UBK systems are fitted with a single High Output UV lamp for 10.000 hrs. Of continuous operation and optimized performance and flow rates.
