Wastewater Treatment & Collection Structure Projects 

The Niwot Sanitation District (NSD) in Colorado USA, undertook a significant project to modernize its wastewater treatment plant (WWTP), driven by the need to meet new environmental standards and replace outdated infrastructure.

For the wastewater treatment plant upgrades at Lift Station 1-2 in the City of Mulberry, Florida, Vogel Brothers Contractors and Pennoni Engineering delivered a durable concrete waterproofing and protection solution using Xypex Bio-San and Xypex Admix C-500, both known for their excellence in wastewater environments.

The Mramorak biogas plant in Serbia, operational since December 2019, represents a pivotal advancement in renewable energy technologies, specifically in converting organic waste into biogas. This project underscores the importance of selecting construction materials that can withstand the harsh conditions of anaerobic digestion—a process where microorganisms decompose organic matter without oxygen, producing biogas but also creating a highly corrosive environment for conventional concrete.

Xypex Bio-San was specified in the precast elements for the Wastewater Treatment Plant Influent Lift Station and Plant in Calvert City, Kentucky. Forterra Pipe & Precast added Bio-San to a total of 180 cubic yards of treated pre-cast concrete for this project.

The Brentwood Equalization Facility in Brentwood, Tennessee, used precast structures in its wastewater management system, integrating Xypex Admix C-500NF Red to combat the harsh chemical environment typical of wastewater treatment. Selected for its durability, chemical resistance, and waterproofing qualities, Xypex Admix C-500NF Red was added to the precast concrete mix during batching.

Sudan, celebrated for its extensive livestock resources with an estimated 104 million heads of food animals (cows, sheep, goats and others), aimed to bolster its meat export capabilities through the new Al Kadaro Slaughterhouse. This facility, sprawled across a land area of 210,000 m2 in the Al Kadaro area, Bahri, boasts a building area of 18,000 m2. Equipped with the latest technology to meet international standards, the slaughterhouse was inaugurated in September 2019, significantly enhancing the Sudanese economy by facilitating meat exports and contributing positively to economic growth.

The Williamsburg wastewater treatment plant project faced the challenge of preventing microbial-induced corrosion (MIC) in its wastewater treatment facility. The original specification called for a polyurethane coating to combat the high concentrations of hydrogen sulfide gas and prevent degradation of the concrete.

Xypex Bio-San C500 was selected due to its ability to permanently waterproof the concrete and increase the structure’s resistance to sulfates and sulfuric acid attacks while preventing the growth of the bacteria that causes MIC.

Xypex Bio-San is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with levels of H2S that cause microbial induced corrosion (MIC). Bio-San combines potent antimicrobial protection along with the unique crystalline technology of the Xypex Admix C-Series.

The designer was concerned about protection of the concrete elements in this tank from the destructive processes associated with microbial induced corrosion. To protect against this Xypex Bio-San C500 antimicrobial admixture was chosen to be added to the concrete mix.
