Water reuse for the bottled water industry
ABSTRACTThe bottled water industry uses a machine specifically designed for the washing of its containers (19-L capacity) and generates 6-L wastewater/container. This effluent can be used for watering of green areas and car washing. The objectives of the present work were to characterize the effluent and to propose a specific treatment to enable reuse of the effluent from the container washing ...

Microbial population responses to pH and salt shock during phenols degradation under high salt conditions revealed by RISA and AFDRA
The responses of microbial community to pH and salt shock during phenols degradation under high salt conditions were revealed by two DNA fingerprint methods, i.e. ribosomal intergenic spacer analysis (RISA) and amplified functional DNA restriction analysis (AFDRA), together with 16S rDNA clone library analysis. It was shown that the phenols removal rate was improved with increasing NaCl ...

Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate
The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

Ex Situ Biological Treatment for Soil, Sediment, and Sludge
The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

In Situ Biological Treatment for Ground Water, Surface Water, and Leachate
The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

In Situ Biological Treatment for Soil, Sediment, and Sludge
The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

Uptown shopping center - Case Study
ChitoVan Chitosan Lactate Cartridge Pretreatment and Sand Filtration Urban development and redevelopment present a host of challenges - not the least of which is managing site stormwater runoff. In a northern suburb of Vancouver Island’s beautiful city of Victoria, BC the stormwater challenge was met and bested through the application of both passive and active chitosan stormwater ...

Chemicals used for pH Adjustment
The Chemistry of Limestone Treatment: Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO3, the primary constituent of limestone) to form water, carbon dioxide and calcium salts. The following depicts the neutralization ...

Brought to Compliance: A Design-Build Delivery for Arsenic Removal in California - Case Study
Bakersfield Well No. 26 in California was experiencing high arsenic levels in multiple groundwater wells when system owner Cal Water sought assistance to resolve the contaminant issue. Arsenic levels had reached 0.012 mg/L and were affecting drinking water for customers throughout the city. To bring the system into compliance and help Bakersfield Well No. 26 meet the arsenic maximum ...

Sea water treatment for shrimp farming - Case Study
Global demand for seafood remains high, yet farming shrimps in aquaculture is a tricky business. Disinfection and desalination systems significantly improve the water quality in the breeding tanks, thereby improving the shrimp survival rate. Task Aquaculture - a growth market Shrimps are a popular delicacy, especially in Europe and the USA. According to the Food and Agriculture Organization of ...

Waste water treatment costs reduced by 50% with rotary vacuum precoat filter - Case Study
Problem: The solids separation system at Lindc's waste water treatment facility had high operating, maintenance and sludge disposal costs. High operating costs were caused by the large pumps and special treatment chemical required to operate the filter, and frequent cleaning, repair and replacement of filter elements resulted in high maintenance costs. Union Carbide Corporation's Linde Division ...
