The aims of water conditioning for industrial use are:-
To prevent formation of scales and deposits on heating surfaces.
To prevent corrosion in boilers or any heat exchange equipments.
To maintain a high level of steam purity in boilers.
Scale prevention is necessary because scale formation and deposits on the heat transfer surfaces, reduce the rate of heat exchange and also introduces the risk of local overheating and consequent failure of the affected tubes. Corrosion rates increase as the temperature increases while the effects of scaling become more serious as the working pressure of the boiler is increased. If corrosion and scaling were allowed to proceed uninhibited, the system would frequently go out of service and the corroded components would require repairs or complete replacement.
It is greatly used in Textile, Sugar and Paper industries and where good quality of water is desired. Also Dairies, Pharmaceuticals and soft drink manufacturers and many other industries using boilers, have much use of this water conditioning chemical.
For Treated Water:
Where external water softening plants are used, the treated water will contain sodium salts and small amount of residual hardness in solution. Reaction may occur between the dissolved solids in water and the metal surface in contact with it. Due to presence of oxygen and dissolved carbon dioxide in water, corrosion of metal slowly takes place. In order to prevent undesirable precipitation and corrosion in feed systems, small quantities of conditioning chemical namely ASWASOF-MP are added to the treated feed water. About 20 ppm (20 gms to 1000 litres water) of ASWASOF-MP is recommended for any boilers working at pressure of about 200 lb/sq.ft. and also for high pressure boilers. Boilers working with lime soda softening plants may require higher dosage in order to reduce the hardness of water and also to maintain phosphate reserve, alkalinity by which to prevent scaling & corrosion.
For Untreated Water:
The dosage can be given on the evaporating capacity per hour of Boiler. On the average, 1.25 Kg. may be added to 10 Tons per hr. of evaporation per shift of 8 hours. However, Phosphate Contents should be checked and they should not be allowed to rise above 50-60 P.P.M. If it is increased, the dosage of chemical should be reduced.
Packing: 10 kgs & 50 kgs
Water Treatment is necessary for :-
Prevention of scale deposits
Prevention of corrosion
Elimination of certain gases
Prevention of priming & foaming
Removal of oils and greases
If no treatment is given then scales and corrosive deposits will be formed when raw water is being evaporated, leaving behind the salt deposits which are backed by heat and slowly get hardened on tubes and shell plates. Due to this, heat exchange capacity is reduced and the system works with less efficiency. Ultimately this may result in more shut downs and even boiler break downs.
ASWASOF-BL is a dark brown liquid, alkaline in nature and is widely used to control scale and corrosive deposits in boilers. ASWASOF-BL, when added to feed water reacts with various salts of magnesium, calcium, sodium, etc. causing it to precipitate and to keep it in suspension. This reacted salts in form of sludge gets removed during regular blow down. Thus ASWASOF-BL helps in keeping boilers clean. The cost involved in using ASWASOF-BL is negligibly low and it keeps plant more reliable and efficient.
ASWASOF-BL is used in various industries such as sugar, textile, paper, pharmaceutical, fertilizer, engineering, cement, etc., wherever boilers are employed for generating heat or steam.
For Treated Water : 10 to 20 ppm (10 gms per 1000 litres)
For Untreated Water : Add about 1.5 litres to 10,000 litres of water. Higher dosage may be
required for water having hardness about 200 ppm.
PACKING : 5 Kgs., 35 Kgs & 225 Kgs
Our above product is mainly used for control of scale and corrosion in the large re-circulating Cooling water systems such as cooling Towers and ponds. It is based on the combination of organo phosponate composition alongwith chelating and dispersing agents.
Our above product has threshold inhibiting property by which it prevents the deposition of calcium phosphate scale. It acts synergistically to inhibit corrosion of metal surface in cooling water systems. Both these properties together make it possible for it to be used at a low dosage level to prevent scale and corrosion. This product is acidic and therefore eliminates sulphuric acid feeding and the hazards of handling associated with it. When used on a regular basis it also works as a slow descalant and helps in cleaning up of heavily scaled and choked systems. It can be used over a wide pH range, has a greater temperature stability and is compatible with chlorine and other non-oxidising biocides. It is most suitable in systems where the water has a greater scaling tendency.
The use of our above product for inhibiting corrosion and the deposition of scales in cooling water systems without using chromates or inorganic phosphates will be more economical and it will reduce the maintenance cost and keep the system clean for a longer time.
PACKING : 5 Kgs,10 Kgs & 35 Kgs.
