Hazardous waste and not, Baioni-Dicatech system

The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

Waste Water Batch Treatment System

Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

Activated bauxite waste as an adsorbent for removal of Acid Blue 92 from aqueous solutions

Bauxite waste, known as red mud, is produced in some industrial processes, such as aluminum production process. In this process, the waste material is produced from leached bauxite as a by product. In this research, the removal of Acid Blue 92 (AB92) dye was investigated from aqueous solution onto the activated bauxite waste (red mud) in a batch equilibration system. Besides, the influences of ...

Acid mine drainage treatment

Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

Alkaline fermentation of waste activated sludge stimulated by saponin: volatile fatty acid production, mechanisms and pilot-scale application

Volatile fatty acid (VFA) production stimulated by saponin (SP), an environmentally friendly bio-surfactant, was investigated during sludge alkaline fermentation in laboratory studies and pilot applications. The combined use of SP and pH 9 condition significantly enhanced VFA production to approximately 425 mg COD/g VSS, which was 4.7-fold of raw sludge and 1.5-fold of sole pH 10 adjustment ...

Management of Hazardous Wastes

' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

Anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW) in two-phase system

In view of recovering energy resource from the treatment of Organic Fraction of Municipal Solid Waste (OFMSW), anaerobic digestion of OFMSW prior to aerobic composting as post-treatment was considered. This study aimed to determine the operational characteristics and efficiency of a two-phase system composed of a fed-batch hydrolysis reactor (phase I) and a methanogenic Upflow Anaerobic Sludge ...

Water mixing in waste lagoons

Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

Minicipal Waste Incinerator Case History

Low temperature plant operation had resulted in severe baghouse corrosion and constant dust blockages throughout the system. It was decided to raise the operational temperature of the incinerator and change the acid gas scrubbing agent from lime to sodium bicarbonate. However, the existing felt filter media could not cope with the change in acid gas scrubbing agent and “blinded” very rapidly ...

Toxins Found in E-Waste

One of the worst effects of a skyrocketing, global e-waste crisis is the risk of toxic contamination for the environment and communities. In fact, delving into the many chemical and heavy metal materials that make up most electronic devices, it seems that toxins and electronics go hand in hand. Though many manufacturers of electronic devices are finding innovative ways to work around toxins found ...

Facilitating Food Waste Digestion

Increasing volumes of commercial food waste, much of it contaminated or packaged, led digestion facility in South San Francisco to install a depackaging unit. South San Francisco Scavenger Company (SSFSC) and Blue Line Transfer, the facility that handles SSFSC’s recycling and disposal, started up its dry anaerobic digester (AD) in late 2014. Situated at Blue Line’s 11-acre site in ...

Komax teflon lined mixer simplifies acid injection for power plant

A major source of waste water in many power plants is the waste stream that results from ion exchange used for demineralizing the boiler feed water. The alkaline regeneration waste stream produced by the ion exchange process requires the addition of an acid to this stream before discharge from the plant. Regulatory authorities typically require the effluent to have a near neutral pH before ...

Evaluation of second-generation Multistage Wastewater Treatment System for the removal of malodors from liquid swine waste

Wastewater quality and malodors in a second generation implementation of environmentally superior technology (EST) were monitored over three cycles of pig (Sus scrofa) production and 15 mo. The wastewater treatment system consisted of three modules: solids separation, biological N removal, and P recovery/wastewater disinfection. While approximately more than 90% of the wastewater suspended solids ...
