The city installed a 3 to 6 MGD desalination facility for the production of drinking water and must overcome significant challenges as outlined in their 40-year Water Development Plan.

The James River Treatment Plant, owned by Hampton Roads Sanitation District, has upgraded to meet the Total Nitrogen mass load in order to produce an annual average concentration of 10 mg/l.

"The carbon footprint analysis was conducted considering both the embodied carbon for the construction and implementation of the alternatives as well as the operational equivalent CO2 emissions for power, methan (CH4) and N2O."

A carbon footprint analysis was performed comparing tertiary filtration technologies: the Kruger Hydrotech Discfilter and conventional sand filters. The Hydrotech Discfilter employs woven cloth filter elements installed vertically on multiple discs, supplying a large filter area with a small footprint.

The Fairplay Sanitation District was challenged in meeting their ammonia permit limits and wanted a process that would produce a stable effluent in a small footprint. Influent water temperatures were regularly recorded in between 6°C and 10°C. Due to these cold temperatures, nitrification was not being achieved on a consistent basis.

The City of Palm Coast, located on the east coast of Florida, expanded their existing Wastewater Treatment Plant (WWTP) to increase capacity to 6.83 MGD due to population growth, as well as add the production of reclaimed reuse water for use within the City.

ACTIFLO® - Hydrotech Discfilter

The state of Minnesota instituted a new water quality requirement that limits cities along the Minnesota River to a 1 mg/L Total Phosphorus limit by 2015 to prevent algae blooms and resulting pollution problems.

The Hydrotech Discfilter system has allowed the Oconomowoc WWTF to consistently meet effluent TSS limits and increase capacity. The system fits within the existing facility footprint and hydraulic profile. In addition, the City has realized substantial cost savings.

The Monteray Shores WWTP needed to increase treatment capacity and improve effluent quality to meet new nitrogen and phosphorus limits within the existing constrained facility site.

The City of Buffalo faced challenges such as rising disposal costs, odor issues, and increase in plant capacity while needing to meet EPA 503 Class A standards all in a limited site footprint. Kruger supplied the BioCon® Biosolids Dryer and Energy Recovery System to meet those needs.
