  1. 1. Issued by the Produc t Managem ent Group WT Divis C ion COOL SOLV - SRWT 1121.. ANTISCALANTDescription Cool Solv SRWT-1121 is a concentrated liquid formulation containing organic polymers.Uses Cool Solv SRWT-1121 inhibits scale formation in R.O. and Thermal Desalination Systems due to calcium carbonate, calcium sulphate and barium sulphate and strontium sulphate deposits with little or no acid feed. The product works through crystal distortion and sequestration mechanism.Features Cool Solv SRWT-1121 is completely water soluble. It has effective deposit prevention capability even at highly alkaline pH Unlike the phosphate based scale inhibitor Cool Solv SRWT-1121 works at significantly low dosage level. It is also more versatile because it can prevent deposits of both carbonate & sulphate salts of Calcium, Barium and Strontium. The product is compatible with all types of membrane and will not violate membrane warrantees. The product is highly effective in any Thermal Desalination system.Applications Cool Solv SRWT-1121 is a specially designed chemical program for excellent deposit control in reverse osmosis (RO) and Thermal Desalination systems.Dosage Cool Solv SRWT-1121 dosage generally varies from 3 to 15 ppm. Exact dosage level depends on the type of membrane and the system dynamics / characteristics. For potable drinking water system- maximum permissible dosage level is 10 mg/litre. Cool Solv SRWT-1121 should be fed through a pump to a membrane system prior to the final cartridge filter. If media filtration or activated carbon is used, polymer should be applied after these treatment stages. In case of Thermal Desalination systems the feed point will be at the feed water intake line.Typical Odor and Appearance : Clear Yellow/Brownish liquid withProperties characteristics odor Sp. Gravity : 1.271 at 250C Boiling Point : 1040C Solubility : Highly Soluble PH : 11.0 - 11.5Benefits Cool Solv SRWT-1121 prolongs membrane life and thus lengthens the time between membrane cleanings. It also eliminates or minimizes acid feed. In case of Thermal Desalination systems the product will increase system run lengths.Handling Avoid contact with skin and eyes. In case of contact, flush with water for few minutes. Remove contaminated clothing and launder before re-use.Storage The product should be stored with their seals intact, in conditions that avoid extreme temperature. Under the above conditions the shelf life of the product would be approx. 2 yrs.Packaging Cool Solv SRWT-1121 is available in 30/50 litre HDPE jerricans/barrels.Product Cool Solv SRWT-1121 can be supplied on request from Dorf Ketal’sAvailability manufacturing site at Taloja near Mumbai. For details contact Dorf Ketal’s marketing department.
  2. 2. COMPANY PROFILE:Dorf Ketal – a leader in Speciality Chemicals needed for oil exploration; refining & petrochemicalprocess applications formed its water treatment & fuel additives division in 2001 in collaborationwith Chemtreat, USA.Company has following quality certifications  ISO 14001:1996  OHSAS 18001:1999  ISO 9001:2000  Frost & Sulivan Award 2005  Emerging India Award.With its state-of-the-art manufacturing, R&D and analytical facility in Taloja near Mumbai and ateam of qualified engineers. Dorf Ketal can provide solutions for any water treatment problems.Dorf Ketal’s WTC division has cutting age technologies which encompasses following areas: -. Technical / Troubleshooting support for various industrial applications. Classroom & on site Training programs. Joint visits with our Agents/Dealers whenever needed to ensure that customers get maximum benefit from the water treatment programs. Trailer made programs for specific industrial applications. Providing various monitoring tool for various water treatment applications.
  3. 3. OUR APPLICATION AREADorf Ketal has products to solve any kind of problem related to Cooling and Boiler water system.We recently developed products in our fuel additive division for different fuel application.  Cooling Water System:Generally there are three major problems encountered in an industrial cooling water system, vizCorrosion, Scaling and Microbiological growth. Each of these require specialized chemicals tominimize the effect on plant performance and improve productivity. Please find below a briefdescription of the individual cooling water product applications;  Corrosion Inhibitors:These are multifunctional products mainly used for control of both corrosion and scaling in anIndustrial cooling water system. It contains organo-phosphate, ortho-phosphate, poly phosphate,zinc, molybdate with the combination of powerful dispersant depending upon the application.  Polymers:Dorf Ketal has a wide range of polymers in its product range. These are useful in controllingscale and deposition in applications where the cooling water has high hardness, high TDS level& high heat load. Dispersants also help in dispersing suspended particles, minerals salts andorganic materials.
  4. 4.  Non Oxidizing Biocides:We have Broad spectrum biocides to control microbial species like, bacteria, fungi, and algae bydifferent mechanisms. Our product range consists of various chemistries like, Isothiazolene,Quarternary Ammonium compounds, TBTO, DBNPA, Bronopol, Carbamate etc., based biocides. Boiler Water System:Industrial boiler water systems mainly encounter problems due to oxygen pitting, scaling andcorrosion. These if uncontrolled can cause rapid failure of boiler tubes which in turn lead toequipment failure, loss of production and energy losses. Which would result in reduced boilerefficiency and increased downtime.  Dorf Ketal Products:Dorf Ketal has developed products to protect the completeboiler water system from oxygen related corrosion, scalingand deposition. We have a whole range of oxygen scavengersfrom Catalyzed sulfite, Hydrazine and DEHA which canprotect the boiler water system from oxygen pitting. Thesecan be applicable for low, medium as well as high pressureboilers. We also have pH boosters and neutralizingamines/Filming amines are available to prevent corrosiondue to low pH in condensate line.
  5. 5.  Antiscalant for R.O. System: Dorf Ketal has developed a comprehensive product in R.O.application. It is a polymer based product mainly used to prevent membrane fouling from deposit forming species and increase plant run length and hence increase membrane life by reducing cleaning frequency. Thermal Desalination :Dorf Ketal has developed a next generation antiscalant to maintain aid in ThermalDesalination operations. Some of the product benefits are given below, Prevents the formation of typical evaporator scale. Effectively controls carbonate as well as sulphate scale formation in a multistage thermal distillation process. It is NSF approved for use upto 10 ppm. It has higher dispersing ability for mud, suspended matter and silt. Highly effective in sea water, brackish water and bad quality bore well water. It is multifunctional and can disperse calcium salts and iron oxides much more effectively at high temperatures as compared to standard products and hence will maintain cleaner heat transfer surfaces by better and more effective dispersion mechanism.
  6. 6.  Fuel Additives:In Fuel Additive segment we have various ranges of products which can be used in fuels likeHSD, LSHS, LDO, FO, Coal etc. The main properties are present in our different types of fueladditives are Dispersant, Fuel Stabilizer, Combustion Catalyst, Deposits & Corrosion Inhibitor,Cetane & Lubricity Improver.
