ProPack, a revolutionary media for biological wastewater treatment, represents a significant advancement in environmental sustainability. Developed by Gray Engineering Co. (now part of the Evoqua Water Technologies family), ProPack has garnered widespread recognition for its exceptional performance and environmental benefits.
ProPack is a unique, high-performance media specifically designed for random trickling filter applications. It comprises a variety of materials, typically including:
Random trickling filters are a common wastewater treatment technology. They utilize media, like ProPack, to support a biofilm of microorganisms. Wastewater is sprayed over the media, allowing the microorganisms to consume pollutants as the water trickles through. This process effectively removes organic matter and nutrients from the wastewater.
ProPack is a game-changer in environmental and water treatment. It offers several advantages over traditional media, including increased surface area, enhanced hydraulic performance, low headloss, improved biofilm stability, and a commitment to sustainability. Its application in random trickling filters contributes significantly to improving water quality and protecting the environment.

Scenario: A wastewater treatment plant is considering upgrading their existing trickling filter with ProPack media. They currently use a media with a surface area of 100 m2/m3. ProPack offers a surface area of 250 m2/m3.
Task:
1. Calculate the percentage increase in surface area if they switch to ProPack. 2. Discuss how this increase in surface area will likely impact the treatment efficiency.
**1. Percentage increase in surface area:** * Difference in surface area: 250 m2/m3 - 100 m2/m3 = 150 m2/m3 * Percentage increase: (150 m2/m3 / 100 m2/m3) * 100% = 150% **2. Impact on treatment efficiency:** * The increased surface area provided by ProPack will likely lead to a significant increase in treatment efficiency. This is because the greater surface area allows for a larger biofilm to develop, which in turn means more microorganisms are available to consume pollutants in the wastewater. * This could result in improved removal rates for organic matter, nutrients, and other contaminants, leading to a higher quality effluent. * Additionally, the increased surface area could lead to a more stable biofilm, reducing the need for frequent cleaning and maintenance of the filter.
