Wastewater System Components

These components are found in wastewater treatment systems

Chemical Pre Treatment

Chemical Pretreatment Systems are designed to provide flocculation, coagulation, flash flocculation, pH neutralization and adjustment, metals precipitation, emulsion breaking and other reactions. Through implementation of chemical metering, agitation and pH monitoring, the CPT systems are tailored to the needs of the application.

CPTs are typically used as pretreatment prior to our DAF, SPC and oil water separator systems and can be provided as free standing, individual designs to fit your needs.

Custom tank volumes are offered to match the reaction system to the application. Reaction tanks constructed of steel, stainless steel, FRP and polyethylene are available. Customization and modifications to fit your project needs are offered.

Dissolved Air Flotation (DAF)

Dissolved Air Flotation (DAF), the use of micro-bubble flotation as a solid/liquid or liquid/liquid (or both) separation method, is widely used in industrial and domestic wastewater treatment processes. Dissolved Air Flotation is a well-established separation process that uses micro-bubbles as a carrier phase to remove solids, ions, macromolecules, fibers and other materials, BOD, COD reduction and for sludge thickening.

Air Flotation offers process advantages over such processes as filtration, precipitation, or adsorption using natural and synthetic sorbents and media. The advantages include better treated-water quality, rapid startup, high rate operation, and a thicker sludge, shorter sludge residence time in a secondary clarifier stage and flexibility in changing the operation parameters as the result of active sludge separation.

DAF bubbles are formed by a reduction of pressure of a super air saturated water stream at pressures usually higher than 3 atm. In industrial practice, the supersaturated water is forced through precise needle valves for air control, and clouds of 0.02–0.10 mm bubbles in diameter are subsequently produced and mixed with the incoming waste stream. Once the saturated stream pressure is reduced and the two streams mixed the bubbles attach to the materials being separated and then floats to the water surface. Modern flotation devices and schemes exhibit both high throughput and efficiency.

Products removed: solids, oils, fuels (vehicle/jet), fuel oils, hydraulic fluids, immiscible machining oils, lube oil, transmission fluid, vegetable based oils, animal/vegetable by-products and many other products.
