biocides

Benzalkonium Chloride (BKC)

CAS: 8001-54-5

Quaternary ammonium cationic surfactant biocide with combined disinfecting and algae-killing properties. Low corrosivity makes it suitable for closed-loop systems.

biocides

Bronopol (2-Bromo-2-Nitro-1,3-Propanediol)

CAS: 52-51-7

Fast-acting biocide effective at very low concentrations. Used in oilfield, paper and industrial water where quick microbial control is needed with minimal environmental persistence.

biocides

CMIT/MIT Isothiazolinone 14%

CAS: 55965-84-9

Broad-spectrum isothiazolinone biocide (CMIT:MIT 3:1) for cooling water, paper mills and oilfield injection water. Long-lasting antimicrobial activity at low dosage.

biocides

DBNPA (2,2-Dibromo-3-Nitrilopropionamide)

CAS: 10222-01-2

Fast-acting non-oxidizing biocide that degrades rapidly in water. Ideal for RO membrane systems and short-contact-time applications where persistent biocides are undesirable.

biocides

Glutaraldehyde 50%

CAS: 111-30-8

Non-oxidizing biocide with rapid broad-spectrum kill and biodegradable residual. Preferred for oilfield water injection and systems where chlorine is incompatible.

biocides

MIT (Methylisothiazolinone) 10%

CAS: 2682-20-4

CMIT-free isothiazolinone biocide for applications requiring reduced sensitization risk. Preferred biocide for cosmetics-adjacent and discharge-sensitive water systems.

biocides

Sodium Dichloroisocyanurate (SDIC)

CAS: 2893-78-9

Stable chlorine-releasing disinfectant for drinking water, swimming pools and industrial water. Slower chlorine release than calcium hypochlorite provides longer residual.

biocides

Trichloroisocyanuric Acid (TCCA)

CAS: 87-90-1

Highest available chlorine content (≥ 90%) among solid chlorine disinfectants. Concentrated, slow-dissolving tablets and granules for swimming pools and cooling systems.

decolorants

Decolorant for Textile Wastewater

CAS: 55295-98-2

Dicyandiamide-formaldehyde polycondensate for reactive and direct dye removal from textile wastewater. High charge density for effective color neutralization.

decolorants

Ferrous Sulfate Decolorant

CAS: 7782-63-0

Low-cost iron-based decolorant for acid dye and direct dye wastewater. Combines coagulation with Fenton-like oxidative decolorization at acidic pH.

decolorants

High-Efficiency Decolorant (Quaternary Ammonium Type)

Quaternary ammonium polymer decolorant with dual charge neutralization and adsorption mechanism. Handles mixed dye wastewater including disperse and vat dyes.

decolorants

Hydrogen Peroxide 50% (Oxidative Decolorant)

CAS: 7722-84-1

Strong oxidant for color destruction in textile and paper wastewater. Used alone or with Fe²⁺ catalyst (Fenton reagent) for advanced oxidation of persistent dyes.
