POLY ALUMINIUM CHLORIDE (PAC) – A high-efficiency inorganic coagulant widely used in water and wastewater treatment. PAC destabilizes suspended particles and colloids by charge neutralization... POLY ALUMINIUM CHLORIDE (PAC) – A high-efficiency inorganic coagulant widely used in water and wastewater treatment. PAC destabilizes suspended particles and colloids by charge neutralization and sweeps them out in flocs. It works over a broad pH range and usually produces less sludge compared to traditional alum. PAC is effective in clarifying water, removing turbidity, color, and even some organic matter. It is fast-acting and often more efficient on a weight basis than alum. Rapid Coagulation: Quickly neutralizes negative charges on suspended solids, causing immediate aggregation into flocs that settle or float for removal. Broad pH Efficacy: Functions well in a variety of water pH conditions, often between pH 5 to 9, giving consistent results even if water alkalinity varies. Low Sludge Volume: Yields a denser floc and thus less sludge by volume, easing sludge handling and reducing disposal costs relative to alum or iron salts. High Efficiency: Often requires a lower dose than traditional coagulants to achieve the same turbidity or color removal, making it cost-effective and reducing the ionic load in treated water.

PREFF® FOAMEX-O – A defoamer for wastewater systems that rapidly eliminates foam from the surface of tanks (such as aeration basins or effluent holding tanks).... PREFF® FOAMEX-O – A defoamer for wastewater systems that rapidly eliminates foam from the surface of tanks (such as aeration basins or effluent holding tanks). It is likely a mineral oil or silicone-based formulation (the “O” may denote Oil-based) that spreads efficiently over foam and disrupts bubble structures. PREFF® FOAMEX-O is particularly useful in biological treatment systems, where surfactants and biosurfactants often lead to persistent foaming. It ensures stable plant operation by preventing foam overflow and sensor obstruction. Immediate Foam Knockdown: Upon application, it swiftly collapses and disperses surface foam, eliminating operational nuisances caused by excessive foaming. Aeration Control: In aerobic systems, it inhibits foam blankets that can interfere with oxygen transfer or displace microbial populations from the reactor, enhancing treatment stability. Operational Safety: By maintaining low foam levels, it minimizes foam-related contamination, reduces the risk of carry-over into effluent, and lowers cleaning and maintenance requirements. Read More

PREFF® FIRE – A treatment for the fire side of boilers (fireside additive) intended to reduce soot, slag, and unburned carbon deposits. By using PREFF® FIRE, solid waste (unburned carbon) in the boiler fire side is reduced and combustion efficiency is increased. It likely acts as a catalyst that promotes more complete fuel combustion and modifies ash characteristics so they don’t accumulate as readily, thereby increasing boiler efficiency and reducing cleaning frequency. Soot Reduction: Helps combust carbon deposits fully, lessening soot accumulation in boiler tubes and flues and thus reducing solid waste that must be removed. Efficiency Increase: With cleaner surfaces and more complete fuel burn, heat transfer improves and less fuel is wasted as unburned carbon, raising overall boiler efficiency. Slag Control: Alters slag melting point or structure, making it lighter and easier to remove, preventing thick insulating slag deposits on the fire side. Read More

Essentially, PREFF® SI prevents scale formation on heat exchange surfaces by multiple mechanisms, keeping them clean and efficient. Comprehensive Scale Control: Simultaneously addresses major scale formers – tying up Ca/Mg to prevent their salts from depositing, dispersing silica to avoid glassy scales, and binding iron to stop rust deposits. Colloid Dispersion: Breaks up and keeps fine particles (like silt or clay) suspended so they do not settle and form insulating deposits in heat exchangers. Heat Exchanger Protection: Ensures that cooling/heating surfaces remain free of insulating scale, which maintains optimum heat transfer and lowers energy costs, as well as reduces maintenance frequency Read More
