The treatment of dye wastewater by activated carbon (AC) prepared from rice husk residue wastes was studied. Batch adsorption studies were conducted to investigate the effects of contact time, initial concentration (50–450 mg/L), pH (3–11) and temperature (30–70 °C) on the removal of methylene blue (MB), neutral red, and methyl orange. Kinetic investigation revealed that the adsorption of dyes followed pseudo-second-order kinetics. The results suggested that AC was effective to remove dyes, especially MB, from aqueous solutions. Desorption studies found that chemisorption by the adsorbent might be the major mode of dye removal. Fourier transform infrared results suggested that dye molecules were likely to combine with the O–H and P=OOH groups of AC.
How to Choose the Best Wastewater Treatment System for Your Plant
For industrial companies producing wastewater as a byproduct of their process, some type of wastewater treatment system is usually necessary. Failing to properly treat your wastewater can potentially harm the environment, human health, and your process, in addition to causing your facility to incur heavy fines and possible legal action if it is being improperly discharged into a publicly owned treatment works (POTW) or to the environment under a National Pollutant Discharge Elimination System (NPDES permit). The...
What Is a Cooling Tower Water Treatment System and How Does It Work?
For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and long equipment service life. If cooling tower water is left untreated, organic growth, fouling, scaling, and corrosion can reduce plant productivity, cause plant downtime, and require costly equipment replacements down the road. Butwhat is a cooling tower water treatment system and how does it work? This article breaks down the basics below: Wha...
How Do You Know If You Need a Cooling Tower Water Treatment System for Your Plant?
In order to keep your production flowing smoothly and avoid costly damage to your cooling tower equipment, the proper treatment of your cooling tower water is essential. If cooling tower water is not properly treated, organic growth, fouling, scaling, and corrosion can reduce plant productivity, cause plant downtime, and require costly equipment replacements down the road. But how do you know if you need a cooling tower water treatment system for your plant? Keep in mind thattreatment methods will vary depending...
Common Cooling Tower Water Treatment Problems and How to Solve Them
For companies using cooling towers to remove heat from an industrial process or for cooling large buildings, there are several issues that can surface during the cooling tower water treatment process that we see on a regular basis. Because these issues occur often, it’s important to know what to look out for in advance, perhaps saving you some time and resources down the line. Keep in mind that these issues will vary depending on whether your cooling tower is an open recirculating system, once-through, or...
