This case study explores the approach used to address persistent silica scaling and control more than 400 ppm silica in the brine, resulting in increased system uptime and water recovery while reducing operating costs.
Recovering a System Severely Scaled with Calcium Sulfate
A South American blueberry farm switched to new wells and its RO membranes filled with calcium sulfate scale until one element weighed 129 lbs. A single clean with AWC C-238 broke up the gypsum and cut differential pressure by 53%.
AWC Helps to Eliminate Silica Scaling in RO System with High Iron Feedwater
Chlorine added to meet the EPA’s arsenic rule left a South Texas plant with iron fouling and silica scale, and cleanings every one to two months. With Megaflux® AF and a C-236 cleaning protocol, the plant has run at 80% recovery for years with no scaling.
AWC Extends the Time Between Cleanings for Water Reuse RO in Northern California
A Northern California water reuse plant was cleaning its RO membranes every four to six weeks, 32 times a year. After autopsies and cleaning studies, AWC A-110 antiscalant stretched that to once every 10 months.
AWC Provides Cleaning Solution For Ultrafiltration System at the Cincinnati Zoo
The Cincinnati Zoo’s ultrafiltration system, which recycles stormwater from 14 acres of grounds, was heading for shutdown after a competitor’s cleaning failed. One 6-hour clean with AWC UF-428 more than doubled flow and cut transmembrane pressure from 11.5 to 4 psi.
