Hazard Reduction

Water treatment system designed to control corrosion, deposition, and biological fouling without "bleed-off." Significant reduction in water usage compared to conventional methods because this system does not require makeup water in cooling systems. Bleed-off is the process of flushing water with high mineral concentrations down the drain and diluting the system water mineral concentrations with fresh water in order to prevent precipitation. From current data in Philadelphia, treating 30,000 tons of cooling water with this system saved about 132 million gallons of water.

Large scale anaerobic biotreatment system. Asarco's biotreatment system consists of a settling basin and two anaerobic bioreactors discharged into a rock filter polishing cell that are followed by a final aeration polshing pond. Heavy metal pollution occurs when excavated rocks or exposed underground mines get into water. The West Fork Biotreatment plant does not require conventional chemicals that are often associated with sludge formation nor constant human monitoring and frequent sludge disposal.

Phosphorous-free corrosion inhibitor that protects carbon steel in cooling water by forming a persistent, passivating film on steel surfaces. Traditional phosphorous-based cooling water treatment has suboptimal performance under stressed water conditions, fouling from precipitation with calcium, the need for stabilizers, accelerated corrosion of zinc alloys, and the addition of nutrients that promote bacterial growth. Regulations on the limit of eutrophication of surface water makes cooling water with phosphorous more costly.

Sulfonated polymer membrane technology for cheaper and less energy-intensive water desalination. This technology can withstand higher pressures, allowing for higher water flux and transport rates. These higher rates increase efficiency while lowering costs. The membrane's structure gives it ion selectivity, low electrical resistance, wet and dry mechanical strength, and good dimensional stability in wet and dry conditions. The membrane's resistance to chlorine also makes it a better option than conventional materials that lack chlorine resistance because it avoids the pretreatment process.

High-friction coating that keeps carpet tile in place wtihout additional adhesives, floor sealers, or primers. Eliminates the need for adhesives and reduces labor costs. Reduces materials needed for installation by eliminating the need to primer or seal the floor. Lack of adhesives reduces isntallation time by eliminated the drying process. Eliminates unecessary waste, such as peel and stick film covers. Eliminates VOC off-gassing that is typically associated with floor sealants, improving air quality. Functional under high water vapor emissions.

Exhaust dye process that changes the negative charge of raw cotton when submerged in water to a positive charge, making attraction stronger with negative dye stuff. 20% of global industrial water pollution comes from the treatment and dyeing of textiles. The process uses up to 75% less water than the conventional reactive exhaust dye process. It saves time as the process takes 5.5 hours compared to the traditional 8 hours. Produces less salt than conventional methods (salt traps other toxic chemicals when bound into a solid). 70% lower TDS, makes ZLD plants inexpensive.
