Lead Plating
A Midwest company is plating lead and etching the material with an HCl batch. The resultant wastewater had a lead concentration of 2,000-4,000 ppm. Traditional chemistry (pH adjustment to 9.8, coagulation/flocculation) could only decrease the concentration to 5.0 ppm. The facility was had to retreat the wastewater and only then could reach a lead level of 3.0 ppm. With the use of the IE-061 ...

Effects of oxidation reduction potential in the bypass micro-aerobic sludge zone on sludge reduction for a modified oxic–settling–anaerobic process
Batch experiments were conducted to determine the effect of oxidation reduction potential (ORP) on sludge reduction in a bypass micro-aerobic sludge reduction system. The system was composed of a modified oxic–settling–anaerobic process with a sludge holding tank in the sludge recycle loop. The ORPs in the micro-aerobic tanks were set at approximately +350, −90, ...

The Control of pH and Oxidation Reduction Potential (ORP) in Cooling Tower Applications
The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth, particularly Legionellae. The use of automatic ...

Chemscan mini analyzers monitor sulfite and chlorine levels - Case Study
Problem: The wastewater plants in Clarkson and Guelph, Ontario use chlorine for disinfection but have severe limits on the concentration of chlorine residual that can be discharged. The receiving stream has limited capacity and is populated by aquatic life sensitive to chlorine. The usual approach to this problem is to feed sulfite in sufficient concentration to de-chlorinate the effluent. ...

Selenium Removal
The oil refinery was in search of a feasible solution for the removal of selenium. Discharge permit changes by the EPA require a reduction of 50% from current levels. Integrated Engineers, Inc. was given an opportunity to perform a feasibility test to determine a treatment process as well as estimated operational costs. The best process was to adjust the pH from 7.0 to 10.0 using caustic, ...

Ozone systems for beginners
This paper is intended for people who know a cooling tower when they see one but have little or no knowledge of their care or what part ozone plays. I have tried to make this as simple as possible and there is even a block diagram on the last page to help you out. Ready? Okay, here is what you need to know first: The sole function of ozone use in evaporative cooling towers is to disinfect water. ...

What is Genclean Advanced Oxidation Disinfection?
What is Advanced Oxidation Disinfection? In an overview, advanced oxidation disinfection is a specific treatment process designed to oxidize, disinfect, and remove organic and certain inorganic contaminants from water and wastewater through the generation of hydroxyl radical (OH) and other specific compounds. What is Oxidation Reduction Potential (ORP)? ORP stands for oxidation reduction ...

Biological nitrogen removal in a step-feed CAST with real-time control treating municipal wastewater
The performance of a 18 L step-feed cyclic activated sludge technology (CAST) combined with real-time control treating real municipal wastewater was evaluated. The operation strategies employed pH and oxidation reduction potential (ORP) as on-line control parameters, which can control the durations of oxic and anoxic phases flexibly. The obtained results showed that the studied process had ...

Optimizing Metals Removal
Optimizing Wastewater Metals Removal Making Wastewater Metals Insoluble for Easy Removal To remove metals from wastewater, the metals need to be insoluble (not in solution). Many facilities, such as in the plating operations, use chelating agents to keep the metals in solution thus insuring a uniform and continuous layer of plated metal. Other chelating agents come in the form of ammonia and ...

Taming taste and odor (T & O) problems in a water treatment plant
Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms that ...
