DID YOU KNOW THAT….

the United Nations has declared access to clean water to be a human right?

71% of the Earth’s sur­face is covered in water?

just 0,3% of the world’s water is avail­able as drin­king water?

70%  of the human body is water?

Plants need water to grow. Ani­mals drink water, and water is essen­tial to human life too! Among other things, it regu­lates our blood cir­cu­la­tion and body tem­pe­ra­ture. But water is a scarce, unevenly dis­tri­buted resource.

Whilst, in indus­tria­lized nations, con­stant access to clean run­ning water is a given, people in third world coun­tries walk for hours to the only water source in order to meet their daily needs. Whilst, in some regions of the globe, the soil dries out, other coun­tries have to battle with floods. All this shows how important access to clean water is for our society!

How does Brenntag con­tri­bute to clean water?

Com­pa­nies that treat water in order to ensure a safe and reli­able supply make a vital con­tri­bu­tion world­wide. Brenntag, too, is there to assist whe­rever clean, pure water is essen­tial!

The Brenntag Water Tre­at­ment team pro­vides pro­ducts and solu­tions for drin­king water tre­at­ment, muni­cipal and indus­trial puri­fi­ca­tion plants, and for pro­cess water and coo­ling water tre­at­ment sys­tems in indus­trial ope­ra­tions. The tasks and chal­lenges that need to be addressed here are wide-ranging. They include:

Odour formation

We are all fami­liar with unplea­sant odours in drains and sewers. Among other things, Brenntag pro­vides various metallic salt mix­tures and the inno­va­tive pro­duct Clorious2® for eli­mi­na­ting odours.

Solids-liquid separation

Sepa­ra­ting solids in sus­pen­sion in the water by means of flota­tion, fil­tra­tion and sedi­men­ta­tion* is cen­tral to indus­trial and muni­cipal was­te­water tre­at­ment. Brenntag pro­vides various metallic salts and floc­cu­lants to sup­port these physico-chemical pro­cesses – inclu­ding thi­c­ke­ning and dewa­te­ring of the sludge pro­duced in was­te­water tre­at­ment.

Foam formation

Unwanted foam can form both in indus­trial pro­duc­tion pro­cesses and in was­te­water tre­at­ment. Brenntag offers defo­amers and dea­e­ra­tors that combat or pre­vent this build-up of foam.

Scale inhibition

Unwanted scale and depo­sits can form both in coo­ling water and in other indus­trial pro­cess water cir­cuits. Scale inhi­bi­tors influ­ence and pre­vent the build-up of scale by dis­rupting crystal growth, inhi­bi­ting, chela­ting and disper­sing.

Cooling water and boiler water treatment

In the case of coo­ling and boiler water, the top prio­rity is to inhibit scale and cor­ro­sion; in coo­ling water, con­trol­ling micro­bio­lo­gical activity is also para­mount. Our exten­sive pro­duct port­folio covers the full range of water tre­at­ment solu­tions in open and closed coo­ling sys­tems.

Dissolved contaminants

Com­plexed con­ta­mi­nants also have to be removed during water tre­at­ment. For this, Brenntag offers a broad range of spe­cialty pro­ducts that can be used across a wide pH spec­trum.

Our water tre­at­ment experts work clo­sely tog­e­ther with custo­mers. They ana­lyze the spe­cific task in hand, as they need to under­stand the on-site pro­cesses in order to build a 360-degree view of the tech­nical plant and equip­ment avail­able on the customer’s pre­mises. In water che­mi­stry, for example, there are various dif­fe­rent pro­duct groups and the­re­fore hund­reds of pro­ducts. Our experts need to find out which pro­ducts suit the customer’s indi­vi­dual needs and requi­re­ments, how they might be com­bined with other pro­ducts and how they can be used with the customer’s on-site tech­no­logy. The entire Brenntag team in charge of water tre­at­ment is made up of spe­cia­lists with spe­cific exper­tise and years of expe­ri­ence in this field.

“Besides a broad port­folio of water tre­at­ment pro­ducts, Brenntag also offers application- and pro­cess engineering-related advice. We help custo­mers make optimum use of their plant and equip­ment and advise them on how to use pro­ducts as effi­ci­ently as pos­sible. The aim in working tog­e­ther with our custo­mers is clean water in com­bi­na­tion with an effec­tive use of the pro­duct tailored to their spe­cific requi­re­ments. Our rule is to ensure suc­cessful and sustainable water tre­at­ment,” says Uwe Webers, Director Water Tre­at­ment, EMEA.

* Flota­tion is a physico-chemical sepa­ra­tion tech­nique for fine par­ti­cles that uses dif­fe­rences in the par­ti­cles’ wetta­bi­lity. It takes place in a liquid, often water, and is enabled by injec­ting gas, often air.

Fil­tra­tion is a tech­nique used to sepa­rate or purify sub­s­tances, usually a sus­pen­sion or an aerosol. Fil­tra­tion is one of the mecha­nical sepa­ra­tion tech­ni­ques based solely on phy­sical pro­per­ties.

Sedi­men­ta­tion is the pro­cess whereby par­ti­cles from liquids or gases are depo­sited under the force of gra­vity or a cen­tri­fugal force. The layer of sus­pended solids that forms is called sedi­ment.| Source: Wiki­pedia

Clean water is some­thing many of us take for granted, whe­ther it be from the tap, bot­tled as mineral water in the super­market, in the swim­ming pool or at the car wash. But clean water is by no means a given. What are the par­ti­cular chal­lenges in water tre­at­ment?

UWE Water is an extre­mely important resource, in my opi­nion the most important of all, for wit­hout water there would be no life! The big­gest chal­lenge over the coming years will be to ensure the quan­ti­ties of water required to cope with the advance of global indus­tria­li­za­tion and strong popu­la­tion growth. This can only work if fur­ther water tre­at­ment mea­sures can be deployed to make our exis­ting water avail­able as drin­king water. Water reuse also plays a decisive role. In addi­tion, sys­te­matic was­te­water tre­at­ment helps to pro­tect ground­water and sur­face water, which serve as a drin­king water reser­voir.

What are Brenntag Water Treatment’s main areas of busi­ness and how does Brenntag con­tri­bute to clean water?

UWE Basi­cally, we are active in all drin­king water, was­te­water and pro­cess water tre­at­ment app­li­ca­tions. Proven and inno­va­tive pro­ducts in com­bi­na­tion with an expe­ri­enced team enable us to offer our custo­mers attrac­tive solu­tions. Our custo­mers also benefit from the fact that we are pre­sent throughout Europe; this is so that we are able to offer exis­ting and poten­tial custo­mers that ope­rate trans­na­tio­nally within Europe stan­dar­dized con­cepts. One key advan­tage for Brenntag as a dis­tri­butor in this large and important sector is that we offer solu­tions span­ning mul­tiple pro­duct groups and can the­re­fore con­ti­nuously adapt our port­folio in line with market requi­re­ments.

Brenntag sells a pro­duct called Clorious2®. What sort of pro­duct is it, where is it used and what are the bene­fits?

UWE Clorious2® is a safe, ver­sa­tile and highly effi­cient dis­in­fec­tant manu­fac­tured and mar­keted by Brenntag. Whe­reas con­ven­tio­nally manu­fac­tured chlo­rine dioxide cannot be stored or trans­ported and has to be pro­duced on the customer’s site, Clorious2® is ready to use and always trans­por­table.

New app­li­ca­tions for this broad­band pro­duct are emer­ging almost every day. Several years ago, for example, we started mar­ke­ting this pro­duct solely to combat micro­or­ga­nisms that cause unplea­sant odours in sewers. To name just a few examples, we now use the pro­ducts in the Clorious2® range for various sophisti­cated and some­times inno­va­tive app­li­ca­tions in the auto­mo­tive and food indus­tries and in dis­in­fec­ting drin­king water for human and animal use. Clorious2® has also been shown to be an ideal means of effec­tively com­ba­ting legio­nella bac­teria. Ill­nesses caused by legio­nella bac­teria pose an increa­sing risk to humans. In this case too, Brenntag can make a signi­fi­cant con­tri­bu­tion to society.
