Water Treatment Chemicals

Gotham Chemical Refining sells the most reliable water treatment products the market.

Boiler Water Treatment

Gotham Chemical offers a full line of boiler treatment chemicals that incorporate phosphonates, phosphates, chelants, homopolymers, copolymers, and terpolymers to eliminate scale and deposits.

Our product line includes oxygen scavengers, alkalinity builders, neutralizing amines, filming amines, boil out treatments, and boiler water antifoams.

Boiler Treat – DJ
Multipurpose Boiler Water Treatment

Boiler Treat-DJ is a total all in one treatment package that is designed to prevent deposits, corrosion, and scale build-up on heat transfer surfaces. The ingredients blended into Boiler Treat-DJ incorporate the most modern synthetic polymers for sludge conditioning and dispersency. Alkalinity builders, precipitating agents, oxygen scavengers and steamline treatment complete this boiler water package.

Advantages to Using Boiler Treat-DJ
  • Prevents Scale Buildup
  • Clean Heat Transfer Surfaces
  • Corrosion Protection
  • Convenient Liquid
  • Multipurpose Activity
  • Economical
Additional Boiler Treatment
Products Available
  • Boiler Treat-S — Liquid Oxygen Scavenger
  • Boiler Treat-A — Alkalinity Booster
  • Boiler Treat-D — Sludge Conditioner
  • Boiler Treat-DA — Precipitating/Sludge Conditioner
  • Boiler Treat-Fe — Sequestrant/Sludge Conditioner

Cooling Water Treatment - Tower Treat

Tower Treat is the name brand for a group of corrosion inhibitor products manufactured by Gotham Chemical. These products are unique, high performance inhibitors that prevent corrosion of ferrous and non-ferrous metals in water solutions. .

Tower Treat is a cationic inhibitor that combines with calcium ions to form a tenacious film on the metal surface. Where calcium is low, it adsorbs onto the metal surface to promote surface protection. This chemical activity produces a microscopic barrier to protect metal surfaces from system deterioration.

Tower Treat also contains a threshold inhibitor that is incorporated to maintain good system stabilization and to disperse suspended particles. These formulations are stabilized for use with halogenated biocides and maintains good integrity when these products are used.

Tower Treat-M is “highlighted” as an outstanding product for general applications when a corrosion inhibitor is needed.

Features Included in Tower Treat Products:

  • Biodegradable — good environmental profile.
  • Excellent corrosion performance in high chloride and sulphate waters.
  • Outstanding performance in a wide range of water types.
  • Excellent performance in aggressive water with high total dissolved solids.
  • Excellent corrosion control in calcium chloride brines.

Closed Loop System

Closed water systems are designed to distribute heated or chilled water throughout a designated area. These systems are susceptible to corrosion and scale if not properly treated. The rate of attack depends upon many factors including velocity, temperature, pH, dissolved gasses, dissolved solids, suspended solids and microbial activity. Gotham Chemical formulates products to address these issues and to provide complete system protection.
CST-100 Corrosion Inhibitor for Closed Recirculating Systems

CST-100 provides superior corrosion inhibition to multi-metal systems operating at high or low temperatures. Recommended for diesel and other internal combustion engines, hot water heating systems, chilled water circuits and other closed systems containing ferrous and nonferrous metals.

CST-100 Cooling Water Treatment provides superior corrosion inhibition to multi-metal systems operating at high or low temperatures. This formula is recommended for diesel and other internal combustion engines, hot water heating systems, chilled water circuits and other closed systems containing ferrous and nonferrous metals. Application of CST-100 in engine jacket cooling water precludes the necessity for pre-softening or de-mineralizing these waters and prevents deposits, scale, sludge and resultant losses in heat transfer or mechanical efficiency caused by high mineral waters.CST-100 does not affect non-metal components or seals. Its low toxicity liquid nature permits convenient handling and minimal disposal problems.

Advantages
  • Multi-metal corrosion inhibitor
  • Prevents scale and sludge
  • Chromate-free: low toxicity
  • Built-in color indicator
  • Compatible with antifreeze solutions
  • use in both hot and cold water systems

Biocides

Microbial growth in a water system presents two problems: it reduces water quality and, if left unattended, can "grow" to reduce system performance and life. Biofouling can cause a decrease in water flow rate, a decrease in driving pressure, and can contribute to corrosion of piping and equipment.

Growth of algae, fungi, molds, slime-forming organisms and bacteria that infect open recirculating and once-through systems can reduce system efficiency by as much as 50%. These “unwelcome guests” can be controlled with the proper Gotham Chemical Product.

Biocides
  • Stabilized Bromine Chloride
  • Sodium Bromide Solution
  • Sodium Bromide Solid
  • KATHON® WT Isothiazolin
  • Glutaraldehyde
  • Carbamates
  • DBNPA:  2,2-Dibromo-3-Nitrilopropionamide
  • BCDMH Tablets:  Bromo-chloro-5, 5-dimethylhydantoin
  • THPS:  Tetrakis(hydroxymethyl) Phosphonium Sulfate
  • Polyquat:  Poly[oxyethylene (dimethyliminio)ethylene,dichloride
