BWA's Belclene^® & Belsperse^® scale control products have been specifically designed to meet the most demanding needs of our customers - for both technical performance and environmental acceptability. The maleic, phosphinocarboxylic and phosphonocarboxylic acid technology on which BWA products are based has led to additives which out-perform polyacrylates and acrylic copolymers under a wide variety of conditions.

Bellacide^® products are non-oxidizing biocides which have been designed to solve a wide range of microbiological problems that occur in many different water treatment situations.

Bellacide 325	- Algaestat - Non-oxidizer	Chemistry: Chloro dialkylamino triazine Best algae control biocide in the market  Excellent hydrolytic stability and ideal for long half-life systems Low dosage Synergistic with halogens Not pH sensitive Non-foaming NSF certified for use in cooling towers and boiler/steam lines
Bellacide 350	- Broad-spectrum - Non-oxidizer	Most powerful biocide in the market Excellent killing performance vs. almost all bio-foulants Excellent surface cleaning properties Synergistic with halogens and many non-oxidizing chemistries Very fast acting - hence ideal for shock dose Not pH sensitive Non-foaming US EPA certified

BromiCide^® and LiquiBrom^® are both bromine release agents which have been developed for the control of bacteria, fungi and algae in industrial water systems. Both products provide effective microbiological control over a wide pH range without the need for high free halogen residuals. Therefore less product is needed at less expense.

Bromicide

- Broad-spectrum - Oxidizing type

BCDMH chemistry (bromine chlorine) Excellent biocidal performance Bromine based and hence effective at more alkaline conditions than Cl Availabe in solid and "Gel" forms thus no handling/spill hazards Available in slow-release tablet form for small sumps without dosing pump Available in fast-release "Gel" form for shocking or continous dose systems Easily "pumpable" NSF certified (Standard 60) and B1 White book FDA certified slimicide Easy handling and no spill related issues

BWA's TowerPro® products represent a flexible, multifunctional water treatment program in easy to use tablets.   Towerpro products are developed for the small systems where good service and pumping equipment can not be justified. Towerpro is formulated with the best in class chemistries to deliver excellent performance for scale, corrosion, slime, and algae control.  It also reduces water blowdown to achieve higher water concentration cycles. Towerpro has an extended shelf life and does not cause irritation to the skin.

The Towerpro range:

Towerpro 8031	all-in-one comprehensive water treatment solution for small towers
Towerpro 8039	a scale inhibitor and yellow metal corrosion inhibitor for use in cooling towers, urinals, etc
Towerpro 8040	a combination of non-oxidizing biocides for use in cooling towers, ponds, fountains, etc
Towerpro 7014	a non-oxidizing biocide for use in air-conditioning and comfort systems
Towerpro 8050	a comprehensive corrosion inhibitor for open evaporative cooling towers

TOWERPRO 8031

Small Cooling Towers have a small sump and are typically seen on top of buildings (green / blue / gray coloured cooling towers). They face the same types of problems the larger towers face - i.e. scale, corrosion, and biofouling. However, due to their small size and location, service companies find them expensive to treat as 2 dosing pumps have to be installed and regular visists have to be made, carbouys of limited quantity have to be tranported in small tempos and carried to the terrace (and later disposed).

BWA has developed the Towerpro series as a comprehensive solution to solve all the above problems. The TP8031 tablet, for example, allows you to run a 1m3 holdup tower for 30 days on a single 200 gm tablet which will be able to prevent scale deposition. Simultaneously, it will be able to prevent algal growth and maintain TBC counts within acceptable limits - all this without requring any service!

The key advantages of using Towerpro 8031 tablets are:

• Avoid formulation costs
• Avoid expensive transportation costs to customers (you can courier tablets to customers instead!)
• Avoid storage problems - your customer can store these tablets in his cabinet unlike carbouys which will need tobe stored carefully
• Avoid disposal charges - tablet dissolves completely so no carbouys to dispose
• Ensure good performance - since system is being continuously dosed by the tablet you are getting continuous performance
• Achieve greater customer satisfaction - since tower is always clean (visually and from scale as well), your client is happy
• Maximize business - tablet will get consumed in 30 days (or max 45 to 60) unlike carbouys for which you may need to send techninican for dosing
• Avoid expensive servicing costs - you need to only send your technician once in the month to add a new tablet to the cooling tower

TOWERPRO 7014

With the growth in the IT, hospitality and retail sectors we are seeing an ever increasing number of "centrally air-conditioned" buildings. These are either water-cooled (using small cooling towers as described above) or air- cooled (employing Air Handling Units i.e. AHUs and Chillers), or possibly even a combination of the two.
