Homosassa Springs Dream Home - Case Study
Septic shouldn't be a nightmare for a Dream Home A single-family residence located upon the environmentally sensitive main basin of the Homosassa River in Homosassa Springs Florida (near Orlando) had big plans for their old Florida "vernacular" home design. They had major set-backs from the beginning due to the lot size and location; they also began construction without the proper permits and not ...

EDTA in dairy wastewater and removal efficiency - a case study
EDTA is the most widely used chelating agent for removal of undesirable cations in many industrial applications such as the dairy industry. It is generally considered to be non–biodegradable by conventional wastewater treatment, thereby potentially producing an environmental health risk. Under suitable conditions, however, EDTA has been reported to be effectively degraded by micro organisms ...

Improving Dairy Wastewater
Dairy Wastewater Treatment The typical dairy wastewater treatment system has a “separator” screen that removes about 10-15% of the larger solids from the flush water. The solids are returned as bedding for the cows, and the dairy waste water liquid flows to the first pond. Typically, there are a series of ponds, which rely on anaerobic (without oxygen) digestion to degrade ...

Adsorptive removal of a textile cationic dye from water using tartaric acid modified Bassia longifolia dried leaf mulch
Adsorption of pollutants on chemically modified agro-waste materials is a suitable alternative of costly methodologies of wastewater treatment. In this work, the dried leaves of Bassia longifolia had been used for removing methylene blue (M.B) dye from textile effluent after chemically modifying them with tartaric acid. All the operational parameters of adsorption were optimised and employed ...

Wastewater treatment in a milk-processing company
Description of the plant The accruing wastewater from the production of cheese and milk products is collected in a centralised pump sump and given to a first pre-treatment step. This step includes a separation of bigger parts by a sieve and a flocculation step with a dissolved air flotation for elimination of fats and cheese particles. After that, the pre-treatened water is buffered and ...

Adsorption isotherm of uranyl ions by scales of Corvina fish
Fish scale is a by-product of fishery. The scales are mainly formed by hydroxyapatite and collagen, forming a kind of natural composite with a large specific surface area that intensifies the adsorption process. In this paper, the potential of adsorption of scales of Corvina fish for uranyl ions from nitric solutions was studied. Equilibrium and kinetic studies in adsorption of uranyl ions in ...

Recent Papers on Water Reuse in Irrigation and Agriculture
The long-term goal of this research is to develop the infra-technologies to reclaim effluents from wastewater treatment plants and reuse them for agricultural water demands. The objectives of this were: 1) to study the effects of various wastewater treatment levels on crop growth and yields; 2) to determine the pollution loads from wastewater ...

Decolourisation of Turquoise HGN by anaerobic bacterial isolates from rumen enrichments
Anaerobic bacteria capable of decolourising Turquoise HGN dye were isolated by roll tube technique from enrichments inoculated with rumen fluid and were tested for their decolourisation efficiency under different conditions. The presence of glucose in the culture medium favoured the decolourisation and specific dye reduction activity (equivalent to the reduction of 1 mg dye. hr?1.mg?1 of ...

Solid thickening and methane production of livestock wastewater using dissolved carbon dioxide flotation
Dilute manure is classified as wastewater due to the large quantity of water used in livestock production in Korea. Livestock wastewater treatment is required in order to reduce high moisture content and treat fluids discharged from the digestion process. In livestock wastewater treatment plants, large quantities of CO2 gas are produced at combined heat and power facilities as well as in the ...

The effects of organic loading rate on the performance of an Anaerobic Baffled Reactor (ABR) treating beet sugar wastewater: pilot experiments
A pilot-scale Anaerobic Baffled Reactor (ABR) effective volume 1.2 m³ and four compartments was used for the treatment of a beet sugar wastewater. The effect of organic loading rates on the operational performance was investigated. The experimental results showed that when influent COD concentration varied from 2000 mg/L to 9000 mg/L, the reactor was rapidly started-up with a Hydraulic Retention ...

Tractor Manufacturer
The wastewater from the tractor manufacturing facility was being trucked to a wastewater treatment facility 120 miles away for treatment and disposal of the wastewater. The wastewater consists of heavy cutting oils/lubricants that could not be treated using conventional chemistries. Integrated Engineers developed a treatment process, which involved Floccin. The mixing requirement was heavy to ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

The Miracle In Nordfjord - A Meat Processing Article
Located deep in the mountains of Stryn,Norway- the original plant consisted of an inlet pump station & filter for pretreatment, fat removal and a Salsnes filter for post treatment. The plant also had 8 concrete tanks which were not in use. The municipality was faced with equivalent loading rates of 10,000 PE and the existing system was rated for 5,000 PE so it was either install ...

Rendering
Problem: The meat industry (poultry included) generates some 30 billion pounds of inedible surplus each year. The rendering industry contributes tremendously to efforts to maintain a clean and healthy environment and prevent a waste disposal problem by turning this otherwise unusable material into usable commodities. One challenge they face in creating a clean environment is the treatment of ...
