Luxury Resort Chooses AdvanTex® For Its Low Life-Cycle Costs
Luxury Resort Chooses AdvanTex® For Its Low Life-Cycle Costs

A new luxury resort was planned for a scenic location just outside the small Greek village of Paliouri. With no municipal sewer available, the investors needed a decentralized wastewater treatment system. The system would have to consistently meet discharge limits, allow for future expansion, and offer low life-cycle costs. Also, it would need to operate with minimal odor or sound, so as to go unnoticed by guests.

    Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed

    The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life — from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA Denite technology is treating 450+ MGD in the Bay.

    Like many municipalities in urban and suburban areas, San Bruno’s source water comes both from its own groundwater supply and through a purchase agreement with a major water utility — in this case, San Francisco Public Utilities Commission (SFPUC). And, like many municipalities in California, SFPUC, along with San Bruno, switched from free chlorine to chloramines in 2003 largely to reduce disinfection by-products.

    Packaged Wastewater Treatment For Guantanamo Bay

    In 2001, with the growing population at Naval Station Guantanamo Bay, and expected future growth, a wastewater treatment system was needed to handle the increase in flows. Fluence worked directly with the United States Navy to design an advanced wastewater treatment plant to meet those needs. The intent was to supply four or five large packaged wastewater treatment systems at different locations around the base.

    Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.

Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years
Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years

The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

ABOUT WASTEWATER FILTRATION

Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.

With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
