Liqui-Flux Case Study: Large-Scale Treatment Of River Water For Industrial Use
12/21/2020
Ultrafiltration (UF) is commonly used as a pre-treatment to Reverse Osmosis (RO) to ensure reliable, consistent and efficient operation. As Shandong Hongxin Chemicals Co., Ltd in China recently discovered, this consistency and reliability, along with quick setup and installation times, helped them realize convenience and cost savings.

Retrofit Expansion Of An Ultrafiltration System Using TORAY UF Modules
11/6/2020
The Brazos Regional Public Utility Agency (BRPUA) in Texas operates the Surface Water and Treatment System (SWATS) that treats water from Lake Granbury, fed by the Brazos River. The SWATS facility first began operating in 1988 with clarification, dual media filtration, and electrodialysis reversal (EDR). The plant was upgraded in 2001 to include ultrafiltration (UF) and reverse osmosis (RO) membrane treatment to produce higher quality effluent.

Optimal Ultrafiltration Uses For Beverage And Dairy Companies
6/29/2020
When you’re sipping on a cold soda or snacking on a creamy piece of cheese, you probably don’t really think about what went into making your food or beverage. Aside from the automated production-line machines, one of the most important things that goes into the making of any soda, juice, wheel of cheese, or gallon of milk is water. Producing beverages and dairy products uses substantial amounts of water within production processes.

Mobile Home Park Installs Modular MBR System To Save Valuable Space
5/18/2020
Bay Meadows is a year-round RV and mobile home park located along the shores of Lake Ontario. The facility had been reliant on subsurface treatment, however current regulatory requirements eliminated the option of continuing with that approach. In addition to high bedrock, the lack of available area due to design flow values meant a more sophisticated sewage treatment solution would be necessary.

Low-Fouling RO Tech Keeps Replacement Costs Down At Wastewater Reuse Plants
4/17/2020
By using Toray's low-fouling polyamide composite membranes, the WTPs at the AMATA estates operated the RO systems for more than five years before requiring replacement of the RO elements. This low rate of replacement has considerably helped the end-user save operational and capital costs and is noted as one of the most successful wastewater reuse plants in Thailand.

Butler WTP Solves Membrane Integrity Issues And Meets EPA LT2 Rule With Aqua MultiBore® Membranes
4/13/2020
Butler Water Treatment Plant (WTP), located in Missouri, receives its influent from a surface water impoundment fed from Butler Lake, Maris de Cygenes River, and Miami Creek. Following treatment, it provides potable water to over 300 businesses, (4) schools, 4100 residents and (4) other Public Water Supply districts.

PVDF Hollow-Fiber Ultrafiltration Membranes Selected For Plant Upgrade
4/10/2020
The City of Delaware, Ohio's Water Treatment Plant (WTP) started operating in 1889. Under the EPA's Long Term 2 Enhanced Surface Water Treatment Rule (LT2), the WTP's feed water is classified as Bin 2, which requires a 4-log removal of Cryptosporidium. As a result, the City would convert its 6.0 MGD lime softening plant to a 7.2 MGD membrane treatment facility utilizing a 4.5 MGD ultrafiltration (UF) system to comply. A total of seven proposals were received during the bidding phase of the UF system, which was narrowed down to three based on best projected capital and operating costs and membrane performance. The three selections would be piloted for further evaluation. Read the full case study to learn more.
