Operating Principle of an Oxygen Monitor

The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

Waste Heat as a benefit of VOC Destruction with a Thermal Oxidiser - Case Study

Application Although many look at the energy used to destruct VOCs as an unnecessary waste, Dickinson Legg (now Garbuio Dickinson), the world leader in the design and manufacture of Primary Tobacco Processing Plants saw it as an opportune way to supplement the heat required in their client’s tobacco refining process – in very different ways. Garbuio Dickinson chose an ...

Industrial membrane processes in the treatment of process waters and liquors

A review on pulp and paper industrial membrane processes using a variety of modules and processes is presented. Membranes are mostly used today to purify process waters and to recover coating colours. Ultrafiltration using tubular membrane modules or cross-rotational (CR) filtration has been widely applied for the purification of process waters. The reuse of UF membrane permeate has decreased the ...

The role of process water in pathogen reduction

The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

MIEX Resin Water Treatment Process

The MIEX®1 Resin process was developed in Australia for the removal of natural organic material in water treatment. This novel, truly continuous ion exchange process, is based on the MIEX® resin – a micro size, macroporous, strong base, magnetic ion exchange resin. The resin was specially developed for this application and optimised for reversible removal of negatively charged organic ions. The ...

Waste Water Treatment Processes Explained

SUNCOAST WASTE WATER MANAGEMENT presents AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

Tylosin abatement in water by photocatalytic process

The photocatalytic degradation of a macrolide (tylosin) has been studied using immobilized titanium dioxide as photocatalyst in a laboratory reactor under UV illumination (365 nm). The degradation of the antibiotic and of the reaction intermediary product was monitored by UV spectrophotometry and HPLC. Three photocatalysts (P25 from Degussa and PC105 and PC500 from Millenium) immobilized on glass ...

Flotation processes

Flotation is a process that involves producing small air bubbles in the water being treated. The bubbles then attach to floc particles produced by coagulation (Link?) and flocculation (Link?). The resulting bubble-floc agglomerates are buoyant and so float to the surface of the water where they accumulate as a floating layer of sludge, known as float, before being removed. ...

Sedimentation Processes

Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. When a thick layer of sediment continues to settle, this is known as consolidation. When consolidation of sediment, or sludge, is assisted by mechanical ...

Egg Processing

Problem: This eggplant, located in Southern California, pro¬duces approximately 6 million eggs per week. During the process and preparation of these eggs, some break and fall on the floor where they are washed into floor drains and mixed with the egg wash water. The mixture of broken eggs and wash water is discharged to a balance tank and then sent through a settling ...

The Bioremediation Process

Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic 'bugs' or microbes that live in soil and groundwater like to eat certain harmful chemicals, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. In order for microbes to clean up ...

Effectiveness of priority PAH removal in a water coagulation process

The paper presents results of research on the removal of priority hazardous polycyclic aromatic hydrocarbons (PAHs) (anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[g,h,i]perylene, indeno[1,2,3-cd]pyrene) from water in the coagulation and sedimentation process. Coagulants chosen for the analysis were aluminum(VI)sulfate and two pre-hydrolyzed coagulants – ...

Efficiency and reliability of membrane processes in a water reclamation plant

Performance of a water reclamation plant using ultrafiltration (UF) and reverse osmosis (RO) treating 280,000 m3/d of wastewater was evaluated over 1 year. Statistical analyses were performed on flow rate, temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD5) and total coliforms. Variations in flow rates coincided with those in ...

Reusing water for industrial processes and irrigation in Saudi Arabia

Water is a scarce resource in Saudi Arabia and the public administration and private companies implement water reuse whenever possible. A reverse osmosis plant installed in the Eastern Province of Saudi Arabia helps to treat industrial waste water streams to quality levels that permit water reuse for industrial applications and irrigation. Kemira KemGuard antiscalant is used to prevent deposit ...

Degradation of chlorpyriphos in water by advanced oxidation processes

The degradation of chlorpyriphos by different advanced oxidation processes such as photo-Fenton, TiO2, TiO2/H2O2, O3 and O3/H2O2 was investigated. The photo-Fenton and TiO2 processes were optimized using a solar chamber as light source. The optimum dosages of the photo-Fenton treatment were: [H2O2]=0.01 M; [Fe3 + ]=10 mg l−1; initial pH = 3.5. With these optimum conditions total degradation was ...

Water and soil remediation using cryogenic process

Cryogenic process for surface water and soil remediation is a process that remove contaminants through condensation of chemicals with the used of cryogens depending on the temperature requirements for treatment (see Figures 1 through 3). The cryogens usually have very low temperatures below -180oC with normal boiling points, are as follows: liquid nitrogen (-196oC); liquid helium (-268.93oC); ...

MIEX® DOC Process for Removal of Humics in Water Treatment

INTRODUCTION Humic substances present a significant problem in water treatment by causing colour in water, increasing required coagulant doses, providing precursors for disinfection by-products and causing re-growth in the distribution network. Humic compounds comprise more than 60% of natural organic matter in source waters. Dissolved organic carbon (DOC) is a “bulk” measure of the organic ...
