Parkson offers two options for liquid removal from water and wastewater basins: effluent and supernatant decanters. The Parkson DynaCanter™ is a floating style decanter used to remove treated effluent or supernatant from the upper portion of the basin. The decanter utilizes a flex joint to allow vertical articulation as water levels move between high and low water levels. The decanter collects water from below the surface to preclude foam, scum, or other floatables from the effluent. A standard open / close valve is used in the effluent piping to control flow rate through the decanter. No electro-mechanical components are used inside the basin making operation and maintenance convenient for the operator.

Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.
The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.
Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed — drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
