Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed
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.

City Validates Innovative Reuse Treatment Options Without RO
City Validates Innovative Reuse Treatment Options Without RO

Hollywood, Florida’s 55.5 MGD Southern Regional Wastewater Treatment Plant (SRWWTP) treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 MGD of additional reuse on an annual basis.

MEMBRAY® NHP-Series MBR MEMBRAY® NHP-Series MBR

As part of Toray’s MEMBRAY MBR series, the NHP (New High Performance) module features thin membrane flat sheets that are densely packed into easily interchangeable cassettes. These cassettes allow for a higher packing density than what was originally thought possible with flat plate designs. The thin membranes are also highly flexible and allow for more movement, resulting in increased vibrations during aeration. This helps dislodge sludge and improve cleaning efficiency, all with less energy use. 

Membrane Aerated Biofilm Reactors (MABR) Membrane Aerated Biofilm Reactors (MABR)

This revolutionary aerobic wastewater treatment solution is modular and reduces energy usage by up to 90% compared to conventional treatment.

SEPAREL® EF-120 Hollow Fiber Membrane Degassing Modules SEPAREL® EF-120 Hollow Fiber Membrane Degassing Modules

By employing the DIC Corporation's proprietary hollow fiber membrane, this module can operate in a vacuum of 20 torr or lower. It can obtain high oxygen removal performance even without using nitrogen and can reduce running costs.

Membray MBR Membrane Membray MBR Membrane

Toray's Membrane Bioreactor (MBR) process is a combination of biological wastewater treatment and membrane filtration.

Service Deionization Service Deionization

Evoqua Service Deionization (SDI) is a safe, convenient and cost-effective supply of high-purity deionized (DI) water for a wide variety of applications, including boiler feedwater, laboratory water, ingredient water for pharmaceuticals, food and beverages, industrial processes, microelectronics manufacturing and many other applications — even spot-free rinse water for car washes.

EnviQ™ Submerged Ultrafiltration Membrane EnviQ™ Submerged Ultrafiltration Membrane

QUA’s EnviQ™ flat sheet submerged ultrafiltration membranes have been specially developed to improve the ease of operation and maintenance of MBR facilities. EnviQ’s innovative design offers ultrafiltration quality product water with a stronger and more rugged PVDF flat sheet membrane. The unique features in EnviQ consist of reverse diffusion and specially designed air diffusers, which maximize scrubbing efficiency, lowers pressure and reduces cleaning.

TETRA™ LP Block™ Dual Parallel Lateral Underdrain TETRA™ LP Block™ Dual Parallel Lateral Underdrain

In municipal drinking water applications or pre-treatment for desalination plants using gravity filters, the filter underdrain is one of the most important components contributing to overall system performance and operation — whether a new filter design or retrofitting an existing filter.

TETRA™ Modular Deepbed™ Filter Modular Packaged Filtration Plant TETRA™ Modular Deepbed™ Filter Modular Packaged Filtration Plant

The TETRA™ Modular DeepBed Filter Plant from De Nora Water Technologies is designed as a competitive filtration plant for tertiary effluent from small to medium size sewage works. The Modular DeepBed Filter utilizes the technology of DeepBed filtration that has made the TETRA filter such a successful tertiary treatment process over many years in Europe and the United States.

New Tools For Improving Membrane Bioreactors New Tools For Improving Membrane Bioreactors

Toray Membrane USA introduced an aptly-named product at WEFTEC 2017, the NHP (New High Performance) module for membrane bioreactors (MBRs). Toray's Peter Waldron sat down with Water Online to discuss how the NHP, which features thin membrane flat sheets densely packed into easily interchangeable cassettes, differs from current industry offerings and how these features benefit MBR operation.

Selecting The Right Membrane For The Job Selecting The Right Membrane For The Job

In this Water Online Radio exclusive interview, Fred Wiesler, Global Director of Sales for the QUA Group, discusses some of the company’s key products, including the EnviQ that uses a flat sheet PVDF membrane, and has a .04-micron pore size. It provides ultrafiltration quality water, with the strength of a PVDF flat sheet membrane.

Decentralized Membrane Treatment Technology Decentralized Membrane Treatment Technology

In the early 90s, Bio-Microbics introduced membrane treatment technology, traditionally used in drinking water treatment plants, to the decentralized treatment market. In this Water Online Radio interview, Jennifer Cisneros, Director of Marketing for Bio-Microbics and Chair of the National Onsite Wastewater Recycling Association’s Marketing Committee, discusses the use of the onsite technology at an oyster bar where Total Kjeldahl Nitrogen (TKN) was about three times the level of ammonia.

Next Generation Membranes For Water Reuse Next Generation Membranes For Water Reuse

Born out of UCLA and the California Inner Systems Institute, Water Planet is focused on revolutionizing water reuse through next generation membrane technology. As Erik Hoek, CEO of Water Planet, explains in this Water Online Radio interview, the company has two core technologies.

SEPAREL® PF Series SEPAREL® PF Series

The SEPAREL PF series removes dissolved gases in water through a tube-shaped gas permeable membrane composed of polytetrafluoroethylene (PTFE). Gasses dissolved in water flow through the tube and are removed due to the pressure difference of the gases inside and outside of the tube, thus creating a vacuum outside of the tube. This video explains how the PF series works.

SEPAREL® EF Series SEPAREL® EF Series

The SEPAREL EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. Also, a lower pressure drop means that larger modules can be used. This video explains how the EF series works.

Small SEPAREL® EF Series Small SEPAREL® EF Series

The small SEPAREL EF series is optimized to remove dissolved gases in water applications with smaller flow rates. The EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. This video explains how the EF series works.

SEPAREL® Hollow Fiber Membrane Modules For Liquid Degasification And Aeration SEPAREL® Hollow Fiber Membrane Modules For Liquid Degasification And Aeration

A proprietary technology of the DIC Corporation, SEPAREL hollow fiber membrane modules are optimized for degassing and aerating water. By utilizing an innovative surface skin layer, only gas can permeate in or out of the membrane. This video introduces the benefits of SEPAREL and where is it most commonly used.
