HUWA SAN TR50 Stabilized Hydrogen Peroxide for Modern Water Treatment Systems - ChemEqual

Clean Water is essential to sustain life, and it forms one of the most demanded consumer commodity as well as service throughout the world. Treated water is a critical environmental, agricultural and public health issue. Providing safe water is necessary for human health and development and global awareness of this issue is rising. The presence of bacteria, microbes and pathogen is a concern when considering the safety of drinking water. Meeting the goal of clean, safe drinking water and to protecting source water from contamination is crucial for a healthy society.

Huwa San TR 50 is an aqueous solution of Hydrogen Peroxide stabilized with colloidal silver and other stabilizing materials. It is a wide spectrum oxidizing biocide for water treatment and decontamination from slime, bacteria, virus, molds, algae and other water borne pathogens typically grow in reservoirs, on the walls of transmission water mains and in storage tanks, pipes etc. It is particularly suited to modern water system hygiene management where conventional treatment methods are not viable.

Huwa San TR50’s hydrogen peroxide based disinfectant formulation also destroys hydrogen sulfide and removes ammonia and other nitrogenous compounds that have unpleasant tastes and hinder disinfection. The addition of Silver ions provides residual disinfection qualities to protect the water from waterborne disease throughout the distribution system from treatment plant to the consumer's tap. It is odorless, tasteless, and colorless and is effective in both clear and cloudy water with rapid results. It is highly effective irrespective of temperature and pH variations.

Huwasan is:

ü  approved for use in public water supplies

ü  effective against legionella

ü  effective against pseudomonas

ü  effective against all bacteria and algae

ü  non-foaming

ü  compatible with other cooling tower chemicals

ü  penetrates and removes bio-films

  ü  Eco-friendly: breaks down into water and oxygen— no neutralization required in disinfecting tanks.

Effective Sulfuric Acid Pickling with Rodine 85

Long term use of metal components in industries often makes them susceptible to formation of rust and surface distortion by scaling. In order to maintain surface quality and remove rust, acid treatment is employed. The metal parts are dipped in acid baths to oxidize and remove hard scales and rust layers. But since all acids have a corroding tendency with metals, acid treatment forms a root cause for concern particularly due to abrasive and corrosive loss of precious base metal leading to surface pitting and distortion.

Acid inhibitors are administered in acid pickling baths to prevent loss of base metal after proper pickling. It also helps to extend the life of acid baths. Using of inhibitor in acid solution limits the acid attack on base metal, therefore minimizing base metal loss. A potent acid inhibitor helps to alleviate acid attack on the base metal once the scale has been removed, lending protection to the surface and optimizing acid utilization.

Rodine 85 serves as a soluble, low foaming, liquid corrosion inhibitor formulated for use in conventional sulfuric acid pickling operations. It is an amalgamation of 1,3-Diethyl Thiourea, Formaldehyde, substituted Triazine & O-Toluidine, Propargyl Alcohol and detergent. Rodine 85 is effective on any type of steel, and can be used at any acid concentration. Rodine 85 is an effective inhibitor for phosphoric and acetic acids, as well as sulfamic, citric, oxalic, and sodium bisulfate solutions in pickling and industrial cleaning operations.

Rodine 85 dosage greatly depends on the type of metal, the temperature of operation and the sequence of cleaning operation. The recommended amount of Rodine 85 to be used for pickling is always given in percent by volume of the concentrated acid, regardless of the degree of acid dilution used. RODINE 85 should be used at a concentration ranging from 0.05 to 0.30 percent by volume of the diluted acid regardless of the degree of acid dilution used. In addition, it is recommended that Rodine 85 inhibitor be used at a concentration not less that 0.5% by volume of the concentrated liquid acid or not less that 0.5% by weight of the concentrated solid acid, regardless of the temperature of the industrial cleaning operation.

Rodine 2010 - Corrosion Inhibitor for Boiler Chemical Cleaning

Boiler systems and pipelines associated with power plants and heating systems often face the problem of mineral scaling on the inner linings and transmission bends. This is mainly due to the residual hardness of the coolant water used. While treated water is essential, minute traces of partially soluble salts of calcium, magnesium, strontium, as well as due to silica and ferrous oxides. While scaling may lead to choking and rupture of transmission pipes, oxidation due to unregulated pH of boiler feed water can result in corrosion and pitting of metal. Thus various boiler scale removal chemicals are employed to clean and maintain optimum operation efficacy of boiler systems.

The two primary choices include Ammoniated EDTA and Ammoniated Citric acid for cleaning. They are both weak organic acids and remove mineral scales and oxides by oxidation and metal ion chelating. But as the case with all metal-acid processes, acids often corrode and cause damage to metal surfaces. And damaged/abraded inner linings of boiler pipes have a risk of exploding at high water temperature and pressure. Thus appropriate acid inhibitors are needed to limit the acid attack on base metal, therefore helping check economic loss and ensure safety.

Rodine 2010 is by far the most popular choice as corrosion inhibitor for chemicals used in boiler cleaning. It is a low toxicity, non-flammable, highly soluble low viscosity liquid metal loss inhibitor for use in tetra ammoniated EDTA and tetra ammoniated Citric acid cleaning solutions. Rodine 2010 not only minimizes ferrous metal loss during chemical cleaning of power plant boilers but also effectively prevents pitting and crevice corrosion of metal surface. Rodine 2010 has a maximum operating temperature of 350°F when used with EDTA and 200°F when used with Citric acid cleaning solution with an operational life of 24hours. Laboratory testing has confirmed that it is more soluble than other commercial inhibitors at elevated pH and advantageously permits post-oxidation and dissolution of metallic copper deposits at significantly higher rates than other commercial corrosion inhibitor chemicals.
