The aims of water conditioning for industrial use are:-

 

  1. To prevent formation of scales and deposits on heating surfaces.

  2. To prevent corrosion in boilers or any heat exchange equipments.

  3. 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.

 

Uses

 

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.

 

Dosages

 

  1. 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.

 

  1. 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

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.

AQUACIDE l-65 is a liquid fungicide & bactericide recommended for cooling systems, such as  cooling towers, air-conditioning plants, condensors, spray ponds etc. AQUACIDE l-65 protects water against growth of fungi, algae  and various micro organisms. AQUACIDE l-65  has sufficient bacteriostatic action  and is toxic to most algae. The anti microbial effect of AQUACIDE l-65 increases with increase in ph. AQUACIDE l-65 has been developed to meet the current needs for an efficient biocide having:

  • High antifungal activity
  • High antialgal activity
  • Low mammalian toxicity (dermal & oral)
  • High stability (over wide range of ph)
  • Non corrosive to handle
At the same time aquacide l-65 has the other desirable properties of any algicide :
  • Easily soluble in water with no residues
  • Nonirritant
  • Biodegradable
  • Broad spectrum activity
Dosage :

Aquacide l-65 is toxic to most algae but because of the variation in algae forms the minimum  algicidal concentration required to render protection will vary.   for most common situations a concentration of 40 to 80 ppm is found to be adequate ( 40 ppm = 40 ml. Aquacide l-65 per 1000 litres of water ) aquacide l-65 is recommended both as a prophylactic  and  curative  measure.   aquacide l-65 is clear liquid,  miscible with water. Initially shock dosage may be given of 100 to 150 ppm where heavy growth is observed.   addition to be made on daily basis.

Performance Test :-

The high efficacy of aquacide l-65 may be tested in your laboratory.   into each of two beakers or  glass jars measure out a litre of water.   add to one of the vessel 5 ml  of aquacide l-65.   the other is control. To the contents of both  add approximately equal quantity of algae (about 1 g. ) present in the water cooling system.   mix well with a glass rod or  s. S. Spoon.   observe the growth of algae in the  two  vessels.    you  will  see  the  prolific  development  of  algae  in  the  control   (a   luxuriant green growth)  and  the  disintegration  to  an   impalpable  brown  powder  in  the  water  containing aquacide l-65.

Packings :-
10  &  35  kgs.

Regular addition of aquacide-l65 at very low dosage will prevent growth of algae, fungi, slime and micro-organisms.   aquacide-l65 can be added to both open and closed re-circulating cooling water systems, as well as cooling towers.

Regular addition of aquacide-l65 will keep the cooling system running efficiently without causing any fouling or breakdowns which are caused due to algae or fungi formation. AQUACIDE-l65 is very safe and non-polluting.   aquacide-l65 is available in standard packing of 10 kgs and 35 kgs. AQUACIDE-l65 is manufactured by ashok industry an iso 9001 certified company.

Formation of scale deposits on waterside surface of heat exchangers in cooling water systems has been of troublesome factor to the operators of cooling systems.  For regular production, it is the responsibility of the plant and maintenance engineers to run the plant at maximum efficiency without shutdown of plant for a considerable period.  This trend for longer operation of plants is due to improved process side techniques which can reduce operating costs and turn out higher production with the same equipment and simultaneously decreases the overall maintenance costs.

Control of corrosion and scale deposits has become a necessity.  The deposition of crystals from cooling water is caused by chemical or physical changes in the water resulting in super saturation of the particular scale forming salts or mineral salts in the water.  Scale is adherent deposition of crystals from cooling water is caused by chemical or physical changes in the water resulting in super saturation of the particular scale forming salts or mineral salts in the water.  Scale is adherent deposition of mineral salts which are tightly bound to each other and to the metal surfaces.  Water scale is mainly composed of Calcium carbonate, Sulphates, Silica and Magnesium compounds.
  
Factors effecting scale formation:

1)Increasing temperatures often increases the tendency to form deposits.
2)Changes in pH or alkalinity affect saturation characteristics of various phosphate compounds such as Calcium or Iron Phosphates.
3)Concentration of dissolved solids such as Chlorides, Sulphates, Magnesium and Silica.  Higher concentration of TDS will increase the scale forming tendency of water.
4)Excessive phosphate dosage will form insoluble Calcium Phosphate and if pH is raised above 7 due to poor acid feed, the tendency towards deposition of Calcium or Iron Compounds will increase.
5)Growth of certain micro-organisms also can cause excessive deposition because of their tendency to adhere to metal surfaces.  Along with other contaminants cause corrosion products and choke up the heat transfer efficiency.

What happens if the Scales are allowed to form

1)Heat transfer efficiency is reduced and it is not uniform.
2)Corrosion to equipments, pipelines, valves and undesirable blockages.
3)Unexpected equipment shutdown.
4)Pumping cost is increased.
5)Equipment life is reduced.
6)Production loss due to ineffective cooling and due to shut down.

Prevention of scale:

Method of prevention of scale is either by Ion Exchange or by partial softening of system make up water.  The water softening process removes scale forming ions like Calcium, Magnesium and Iron but it gives rise to corrosion.

Factors effecting corrosion (Electro chemical Theory of Corrosion)

Due to potential difference between two or more points, corrosion occurs.  Metals go into solution at anodic areas by oxidation.  Difference in potential can be caused by several factors such as temperature crystal size and orientation, difference in composition and concentration of dissolved oxygen, use of dissimilar metals, discontinuous oxide film due to air or dissolved gases, etc.  Cooling water is saturated with dissolved oxygen, because the water comes in contact with air when it passes through a cooling tower or is sprayed in a pond.
