Phosphonate removal from discharged circulating cooling water using iron–carbon micro-electrolysis
Phosphonate is a commonly used corrosion and scale inhibitor for a circulating cooling water (CCW) system. Its discharge could cause eutrophication of receiving waters. The iron–carbon (Fe/C) micro-electrolysis technology was used to degrade and remove phosphonate from discharged CCW. The influences of initial pH, Fe/C ratio (FCR) and temperature on phosphonate removal were investigated ...

Creative skimmer solution endures environment and reduces costs
WCI Steel, a steel manufacturer in Warren, Ohio, needed an uncommon solution to a fairly common problem - removing grease and other contaminants from their outdoor circulating water system. They turned to Abanaki Corporation, Oil Skimmer Division in Chagrin Falls, Ohio for the answer. Each week, WCI Steel uses 200 gallons of grease on a roll out table to keep steel slabs from rolling off the ...

DOD evaluates bioaugmentation for remediating low-pH aquifers
The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

Elimination of Lime
In the paper industry limy deposits out of the circulation water in pipes, cooling systems, heat exchangers etc. are being eliminated by the utilization of lime traps. This considerably reduces the fresh water consumption and secures a sustainable improvement of the process reliability. Also the cost for maintenance and service of the systems are reduced significantly. By means of Micro Bubble ...

Wastewater sterilization (purification): completely new method “vortex layer machine”
The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

Methods for Treating Waste Water of Livestock and Fowl Cultivation
Multi-media filter is a process of using one or several filter media to pass water with higher turbidity through a certain thickness of granular or non-granular material under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Commonly used Filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment ...

Food Processing: Odor Control in Edible Oil Processing
Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen hotwell water out ...
