Pencco
About
Pencco (Pioneer Engineering Chemical Company), headquartered in San Felipe, Texas, has manufactured and distributed water and wastewater treatment chemicals for approximately 40 years. The company produces five core coagulant chemicals — Ferric Chloride for enhanced sludge dewatering and struvite control, Ferric Sulfate for phosphorus removal and clarification (described as gentler and less corrosive than alternatives), Ferrous Chloride for odor control, chlorite removal, and heavy metals precipitation, and Ferrous Sulfate for economical odor and corrosion control (non-hazardous, non-corrosive at working concentration). Their proprietary SULFeND RT formulation prevents H2S formation, scavenges sulfur compounds, inhibits biogenic corrosion from sulfur-reducing bacteria, adds alkalinity, and carries a non-hazardous classification. Pencco also distributes Fluoride, Calcium Nitrate (non-hazardous, non-staining, long retention time, reduces dissolved sulfides below 1 ppm), Hydrogen Peroxide (the fastest and most powerful oxidizer), Liquid Ammonium Sulfate (a safer alternative to anhydrous ammonia for chloramine disinfection), Magnesium Hydroxide (non-corrosive, non-staining alkalinity supplement), and Hydrofluorosilicic Acid. Beyond chemical supply, Pencco provides advanced water treatment program design, targeted residual testing for nitrate and iron optimization, and turnkey odor and corrosion control programs that include dosing equipment and ongoing monitoring. The company serves municipal drinking water and wastewater treatment plants, mining operations, industrial water and wastewater facilities, and the fertilizer industry, with manufacturing, distribution, and transportation capabilities across the United States.
