Removing Recalcitrant COD

Removing Recalcitrant COD COD is Chemical Oxygen Demand and is a common analytical tool to measure the strength of industrial waste water. When COD is not reduced by common industrial waste water treatment methods it is often called recalcitrant COD. An example would be industrial waste water containing Phenol. Phenol is toxic to most microorganisms and is difficult to remove. One way to remove this recalcitrant compound is by chemical oxidation using Fenton’s Reagent. Fenton’s reagent is a powerful oxidizer that is generated when Hydrogen Peroxide is in the presence of an iron catalyst. This produces what is called a ... » Read More

Automating the Fenton Reagent Oxidizing Process

Fenton Reagent Oxidizing Process Automating the Fenton oxidizing process is easy to accomplish. The treatment process can be controlled by monitoring pH, ORP (Oxidation Reduction Potential) and Temperature. pH can be adjusted automatically by the addition of an acid or a base by means of chemical feed pump. The chemical feed pump is controlled through a PLC based control panel. The desired pH is set on the control panel and the variable speed chemical feed pump does the rest. ORP measurements are preset on the control panel to regulate the rate and amount of hydrogen peroxide being added to the ... » Read More

Determining if the Fenton Process is right for your application

The Fenton Process Wilson takes a phased approach to determine if the Fenton regent is a feasible treatment method for your industrial treatment process. The first phase, Phase I, is what we call Fenton Screening where COD is measured both before and after treatment to determine percent reduction and give an estimate of chemical cost. If the Phase 1 results are good, that is reaching the desired COD without excessive chemical addition a Phase II analysis is recommended. The phase II analysis examines chemical dosages of iron, hydrogen peroxide, lime, rise in temperature and reaction times. These parameters are the ... » Read More

Groundwater Treatment Building Mural

Ground Water Treatment Building Mural We are working on a large groundwater remediation project in Houston that is located in a residential neighborhood. The groundwater remediation control building is located in the dog run of an upscale apartment complex. Last month the apartment manager hired Salcreations a local Muralist to paint the building. Boy, were we surprised when we saw this. It’s really good looking.

Waste Water Treatment, Design and Build vs. Standard Vendor Unit

Waste water treatment technology is not new. The individual components that make up a complete system are readily available. Standard Vendor Unit As a rule of thumb vendor units are usually designed for flow rates up to 30 gallons per minute (GPM). Vendors state the flow rate as 0 to 30 for a 30 gpm system. It is stated this way because as filters are used they become blocked and the flow will continuously drop off. High contaminate concentrations will also reduce the amount of waste water that the system is able to treat. Design and Build For high contaminate ... » Read More
