Cationic Coagulants

Gardo Pure WT 2081 is a coagulant effective in a wide variety of industrial and wastewater treatment applications. Gardo Pure WT 2081 has been successfully applied in the treatment of oily wastewater, secondary clarification, color removal, paper mill save-all systems, refuse thickening in coal preparation plants, greasy tower treatment and phosphate removal.
Gardo Pure WT 2082 is a concentrated cationic coagulant solution whose neutral composition provides solution charge neutralization and coagulation in final neutralization tanks as well as in acid and alkaline solution tanks.
Gardo Pure WT 2083 is a polymer-based, low molecular weight, highly charged cationic coagulant available in liquid solution form.
Gardo Pure WT 2084 is a heavy metal catalyst used in conjunction with other oxidants. Its primary application is in the destruction of sulfides, where it increases the rate of reaction and improves the oxidant's selectivity. This catalyst should be used when reaction time is an important factor in the destruction of low levels of sulfides.
Gardo Pure WT 2085 is an all-organic product that can partially or often totally replace alum, ferric, lime or other inorganic coagulants, thereby reducing sludge volume for disposal. This product has achieved upwards of 80 percent reduction in sludge volume compared liquid alum.
Gardo Pure WT 2086 is effective in a wide variety of wastewater treatment applications. It has been successfully applied in the treatment of oily wastewater, greasy tower treatment and phosphate removal.
Gardo Pure WT 2087 is effective in a wide variety of industrial and wastewater treatment applications. It has been successfully applied in the treatment of oily wastewater, greasy tower treatment and phosphate removal.
Gardo Pure WT 2088 is a blend of highly charged cationic organic polymers and inorganic coagulants specifically formulated to replace inorganic coagulants, such as aluminum and ferric salts.
Gardo Pure WT 2089 is a medium molecular weight, highly charged polymeric cationic coagulant available in liquid solution form.
Gardo Pure WT 2090 is a blend of highly charged cationic organic polymers and inorganic coagulants. It is specifically formulated to replace inorganic coagulants such as aluminum and ferric salts. It can also eliminate dual treatment applications requiring both cationic polymer and addition of inorganic salts.

Anionic Polymers (Flocculants)

Gardo Pure WT 3021 is an anionic emulsion polyacrylamide that is used as a flocculant or coagulant aid in a wide variety of industrial and wastewater treatment applications. This product has been successfully applied in liquid/solids separation systems such as clarification, thickening, dewatering, flotation and filtration.
Gardo Pure WT 3022 is dilute anionic solution polymer used as a flocculant or coagulant aid in a wide variety of industrial and wastewater treatment applications. These products have been successfully applied in liquid/solids separation systems such as clarification, thickening, dewatering, flotation and filtration.
Gardo Pure WT 3023 is an anionic dry polyacrylamide that is used as a flocculant or coagulant aid in a wide variety of industrial, including wastewater treatment systems. This product has been successfully applied in liquid/solids separation systems such as clarification, thickening, dewatering, flotation and filtration.

Cooling Tower

Gardo Pure WT 6061 is corrosion inhibitor is a molybdate-based product for corrosion control in closed cooling water systems. This product also contains a specific inhibitor for copper and copper alloys and a polymer for dispersion of hardness salts.
Gardo Pure WT 6062 is a concentrated, liquid blend of organic and inorganic components designed to provide complete cooling water treatment in a variety of recirculating cooling water systems.

Boiler Water Treatments

Gardo Pure WT 1020 is a highly effective polymer-based deposit control treatment designed for use in low- to mid-pressure boiler systems. The product also contains molybdate for testing, control and diagnostic purposes.
Gardo Pure WT 1027 is a highly effective, easy to feed and control, liquid corrosion and deposit control treatment for steam generating systems. A polymer-based program, Gardo Pure WT 1027 advances this proven technology by combining a thermally stable, iron-tolerant polymer with a threshold deposit inhibitor and select corrosion inhibitors. By combining these components into a single product, a total treatment program can be provided.
Gardo Pure WT 1041 is used to prevent corrosion in steam generating systems by removing dissolved oxygen from the feedwater and boiler water. Gardo Pure WT 1041 reacts with oxygen in water almost instantaneously even at low temperatures. This rapid rate of reaction provides greater protection to the boiler and pre-boiler section, especially where mechanical deaeration is not complete.
Gardo Pure WT 1063 is corrosion inhibitor used to control corrosion in the after boiler section of a steam generating system by neutralizing the acidity of the condensate. Gardo Pure WT 1063 contains a volatile amine to neutralize carbonic acid. The amine used in Gardo Pure WT 1063 has a distribution ratio which allows it to condense in both high and low pressure sections of the steam/condensate system.
Gardo Pure WT 1068 is a blend of neutralizing amines for use in steam condensate systems. The amines in Gardo Pure WT 1068 volatilize with the steam and neutralize carbon dioxide and other acidic contaminants, protecting the lines against corrosive attack. The selected amines provide effective protection in initial, intermediate, and distant portions of the steam condensate system, in systems with multiple condensation sites and systems with complex letdown designs.

Defoaming Agents

Gardo Pure WT 8477 is a foam control agent composited of a proprietary blend of mineral oil, silica derivatives and surface active compounds designed to control foam in a variety of industrial processes, including latex and adhesive production, and wastewater applications.
Gardo Pure WT 8479 is a quick-dispersing, hydrocarbon oil-based antifoaming agent, is designed for use where immediate foam-control action is wanted. It is particularly suitable where addition adjacent to the foam-control point is required. Its efficiency is not adversely affected by temperature or pH, and it is effective in the presence of many surfactants.
