  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • How Not to Lose Cadmium While Measuring?

    Today cadmium finds a better usage than a hundred years ago. For example, metal cadmium plating is used for anticorrosion coatings that are more stable than zinc, nickel and tin-plated. Cadmium plating of steel parts gives greater resistance to corrosion, especially in sea water. About 20% of cadmium goes to the manufacture of cadmium electrodes used in ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth. But the single most effective method of controlling mold is to eliminate their source of moisture. Moisture doesn’t just mean actual water; it can also be high humidity. Few molds grow when the humidity is under 70%. If they do, it is very slowly. It is safe to say that you cannot stop mold growth until you stop the moisture. ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • Erosion control products: cost effective alternatives for revegetation

    Erosion is any horticulturist’s worst nightmare. From the process of replanting and restoration, to the loss of the most fertile soil, i.e. the topsoil, erosion can have damaging effects on any cultivation. Although erosion is mainly associated with water erosion, wind erosion and tillage are another two forms of erosion. So what are the signs that can help identify erosion early ...

  • Composted Woody Materials Become Erosion Control Product

    In Beaverton, Oregon, Lakeside Reclamation, Inc. grinds incoming yard trimmings and other feedstocks which are composted and bagged for use in erosion and runoff control. The facility recycles over 25,000 tons of wood each year for multiple product use. Owned by Howard Grabhorn, the site includes a limited purpose landfill, composting area, retail products building and comparative erosion control ...

  • Control of malodors using Ecosorb - A natural product

    Abstract Ecosorb removes many malodors, including sulfur dioxide, hydrogen sulfide and ammonia, from the environment. It is made up of a combination of essential oils consisting of an equilibrium of neutral organic compounds and organic buffers. Its pH ranges from 4.0 to 6.8. Acidic malodors such as hydrogen sulfide and sulfur dioxide are removed by at least four mechanisms ...

  • Control of disinfection by products formation potential by enhanced coagulation

    Abstract Jar-test experiments were conducted to study enhanced coagulation effectiveness in removal of disinfection by products (DBPs) from Zayandehrud River at Isfahan Province-the center part of Iran- in 2004. In this study, the removal of suspended and colloidal particles and natural organic matter (NOM) at various coagulant doses and coagulation pHs was assessed through raw and treated ...

  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...

  • N-nitrosamines, emerging disinfection by-products of health concern: an overview of occurrence, mechanisms of formation, control and analysis in water

    The presence of N-nitrosamines in water bodies used for drinking water purposes may present a more serious risk for humans than regulated disinfection by-products (DBPs) species. Hence, understanding and controlling the incidence of N-nitrosamines represents a contemporary challenge to the water industry. Although many of these molecules potentially formed as DBPs are detected in chlorinated ...

  • Cost-Effective Control of Interdependent Water Pollutants

    Abstract  Excess nutrient loads to coastal waters lead to increased production of algae, which when decaying cause oxygen depletion in bottom sediments, which in turn leads to major changes in marine ecosystems. A cost-minimization model was investigated in which nitrogen and phosphorus were assumed to interact with respect to algae production. It was investigated under what conditions only ...


  • Case History - Sale of By-product HCl Covers Cost of Emission-Control System

    Problem: Some of the specialty chemical processes at a major chemical manufacturer's plant result in considerable HCl loading in the off-gas. The HCl must be removed before the off-gas can be discharged to the atmosphere. Production of saleable by-product HCl solution was an important goal when looking for a high-efficiency HCl removal system. The company wanted to achieve a very low ...


  • Case study - Neutralization basin odor control for agricultural chemical production

    Challenge: An agricultural plant located in the Midwest manufactures herbicides, pesticides, fungicides, and insecticides. Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As ...
