Water used in industry | its importance - specifications - methods of treatment


The use of water in the industry - water treatment in the industry - water industry - removal of water hardness - water sterilization in industry - water specifications used in general industries and detergents, especially since these broad titles concern many industrialists and small entrepreneurs before starting the project.....

You started a project to make liquid detergents and you had a problem with the water used.

For example, you found that water causes turbidity in products (you have to address the problem of Water hardness) and you found that the water used leads to sediments, suspended materials or dust.

(What is the solution?)

Or the water used caused rot in the product and the appearance of a bad smell

(What is the solution?)

If you want to answer these questions follow this article to learn accurately and in detail about the importance of water in any industry and how to treat it and ways Sterilize them and we will single out the detergent industry.


Introduction to the importance of water:

Dear reader, most industries around the world need to use water, whether directly, such as industries where water is a major component such as detergents, food or medical industries. Etc. or indirectly such as industries that use water for heating, cooling or cleaning.... So the treatment of the water used is of great importance.


The importance of water treatment:

  • The use of treated water increases the quality of the product and improves its specifications.
  • The use of treated water increases consumer confidence in this product.
  • The use of treated water increases the operational life of machines and devices.
  • The use of treated water reduces the cost of production as by increasing the life of machines will not require many interruptions of work for maintenance and cleaning work
  • In particular, the detergent industry is added to the above mentioned increase disage of the product where it prevents the formation of bacteria that lead to rot


The most important water problems in the industry:

  • Hardness and calcification TH
  • Taste and smell
  • TDS Dissolved Salts
  • Turbidity and impurities
  • iron
  • Germs - Heavy metals - Oils - Acid water


Specifications of water used in the detergent industry:

1- Water Hardness: It is caused by the presence of calcium salts and magnesium and is divided into two parts temporary Hardness and permanent Hardness

Temporary Hardness : is caused by the presence of bicarbonate salts and some other salts and can be removed by heating the water until boiling and turning into a deposit and separated by the filtration process

permanent Hardness is mainly caused by calcium salts and magnesium in water in the form of carbonate, sulfate or chlorides and cannot be removed by boiling and must be treated in waysPhysical and chemical be expensive should be the harshness of the water used in the manufacture of detergents at a very low rate and preferably the use of distilled water removed electrolytes if possible


2. Germs (germ colonies): Here the water containing germs must be treated because it causes the quality of the product to be reduced and leads to the rot of the products


The most important water analysis required in the industry:

We'll remember the most important analyses quickly, and we'll talk about them in detail in a separate matter.

  • Total hardness (total hardness of water) TH
  • THM total hardness Magnesium
  • total hardness permanent THP
  • TA total alkalinity
  • TAC complete alkalinity
  • CO2 gas
  • Residual free chlorine CL2
  • Chemical analyzes of the ions Ca - Na -Mg - K - Fe - So2 - Co3 - Cl - No3.
  •   Microbial colonies
  • Heavy metals


Methods of processing and disinfecting the water used in the industry (detergent 


1- Water hardness treatment:

Water hardness treatment:


There are several ways .To treat the hardness of the water and from it

- Industrially using the devices to remove the cruelty and calcification that work on the principle of katyonri resins where the rizine in the device takes calcium electrolytes and magnesium from water and give suard sodium and may be small devices or large stations



- For small projects that do not bear the cost of a desalination plant, EDTA salt can be used, which reduces the hardness of water by depositing magnesium and calcium electrolytes.



2- Treating the taste and smell:

Treating the taste and smell


It depends on the cause of taste or smell and can be treated with ventilation or using active coal

active coal


Which absorbs the taste, smell and chlorine in water or using oxidized chemicals if the cause is the presence of sulfates and then we filter the water


3- Treatment of dissolved salts TDS:

Treatment of dissolved salts TDS


The water treatment device of the dissolved salts of reverse osmosis, which is the salts dissolved in the water as it passes through the layers of the earth (e.g. salts sulfates, nitrates, chloride, sodium and calcium .... Etc.) this problem can be addressed by using reverse osmosis devices

reverse osmosis,


4- Treatment of turbidity and impurities:

Treatment of turbidity and impurities


The containment of water used in the industry on sand or impurities or suspended materials causes major problems such as sediments and blockages, which affects the work of machines and equipment and shortens its operational life, so the problem of turbidity can be solved using sedimentary basins and deposits with chemicals or using multiple-layer sand filters.


5- Addressing the problem of Fe iron:

Addressing the problem of Fe iron


Treatment is carried out in addition to sodium hepo chloride or ozone-generating devices or chlorine injections depending on the quality of the water, the quantity required and the cost required, and the method of treatment with sodium hypochlorite (water javelin) is the cheapest and easiest


6- Treatment of heavy metals, oils and acid water:


Heavy metals are processed using devices containing special resins for each metal, either floating oils can be removed by means of charcoal filters or special skimmers and acid water is treated with chemicals that modify the value of Ph

So we have known the most important problems that occur due to the water used and the methods Address it, where you may face one of these problems when you start your own project such as having water high severity or may contain sediment or high iron percentage or any heavy metal or maybe it has germs so you should be aware of these things to find the right solutions to the problems you may face
