Capital Construction

An overview of waste-water treatment alternatives in South Africa is presented. A comparison of the capital, operating and maintenance costs of biological filters, bio-discs, stabilisation ponds and an extended-aeration-actiyated sludge system suggest that stabilization ponds may be regarded as a low cost, low energy waste-water treatment system. However, in some instances, due to legal and land requirements they are not appropriate. In these instances a number of interacting factors play a role in determining the lowest cost option. The capital construction and operating costs of constructed wetlands are similar to those of stabilisation ponds but due to lack of full scale operational information they are not yet widely used as a waste-water treatment system.

Dairy wastes are a source of nutrient pollution of surface and ground waters in high rainfall areas of south west Western Australia. Many of the state's 546 dairies are sited over soils that are either sandy, leading to pollution of ground waters, or clayey, causing reductions in surface water quality. Awareness of the environmental implications of their activities is motivating dairy farmers to join Land Conservation District Committees, where water quality improvement is a primary goal. A low cost treatment system has been designed to reduce the water pollution potential of dairy waste. It incorporates three stages: a sump in which anaerobic digestion occurs; an aerobic vegetated filter with a base of permeable phosphorus-absorbing material; and an irrigated plantation or crop using water that has passed through the system. This paper describes the theoretical background to the design.

Aqua Renaissance' 90 is a six year R & D project for water reuse and energy recovery supported by the Japanese Ministry of International Trade and Industry. The objective is to develop low cost treatment processes utilizing bioreactors coupled with membrane separation units to produce reusable water from industrial waste water and sewage. Polymeric and ceramic membranes in capillary, hollow fiber, tubular and plate and frame modules have been tested in conjunction with bioreactors on a number of actual waste water and sewage streams. This paper will focus on membrane performance and power consumption. Recent results from test plant operation indicate that treatment of concentrated waste water by membrane separation units uses less than a third of the conventional power requirement.

Removal Of Arsenic

Because of its threat to the quality of freshwater resources and human health, arsenic (As) pollution is important to scientific communities and policymakers around the world. The Mekong Delta, Vietnam, is one hotspot of As pollution. Its risk assessment of different environmental components has been well documented; however, very few studies focus on As removal techniques. Considering this information gap, this study aimed to investigate the performance of an innovative and low-cost treatment system using Fe(III)-oxyhydroxide (FeOOH) coated sand to remove As(III) from aqueous solution. Batch and column experiments were conducted at a laboratory scale in order to study removal kinetics and efficiency. Experimental results indicated that the adsorption isotherm of As(III) on FeOOH coated sand using Langmuir and Freundlich models have high regression factors of 0.987 and 0.991, respectively. The batch adsorption experiment revealed that contact time was approximately 8 h for rough saturation (kinetic test). The concentration of As(III) in effluents at flow rates of 0.6 L/h, 0.9 L/h, and 1.8 L/h ranged from 1.1 µg/L to 1.7 µg/L. Results from this study indicated that FeOOH coated sand columns were effective in removing As(III) from water, with a removal efficiency of 99.1%. Ultimately, FeOOH coated sand filtration could be a potential treatment system to reduce As(III) in the domestic water supply in remote areas of the Vietnamese Mekong Delta.

Effluent Waste

Demand for milk and milk products caused vast growth of dairy industries in most countries of the world. Consequently, the amount of wastewater and waste material generated and discharged from these industries has also increased. Phytoremediation provides eco-friendly, low cost treatment approach for the waste water treatment. In the current study aquatic macrophytesEichornia and Lemna were taken in account individually and in combination. A wetland approach was used for the treatment of effluent (waste water) from Parag Dairy and Milk processing plant, Meerut. Effluent was then transferred to glass aquarium and analysed for Physico-chemical parameters viz. Temp., pH, Turbidity. The initial parameters of the raw waste water were recorded Temp 25.34oC, pH 5.8, Turbidity 648 NTU. After the treatment, 75 % removal of turbidity was recorded in case of Eichornia (486 NTU), while Lemna showed a potential of 54 % removal (350 NTU) of turbidity

The motive of this paper to prepare some systematic low-priced and sustainable domestic waste water treatment system for household. To acquire this objective we collected samples from the household kitchen sink, basin, laundry etc. From the conclusion we learned that the tested parameters like BOD, COD, TDS, etc. displayed high removal of physical and chemical impurities. The treated water can be used for purposes such as irrigation, car washing, Flushing, etc.

Abstract In this study, polyaniline (PANI) is prepared by means of chemical oxidization polymerization and directly loaded on the modified fiber ball (m-FB) to obtain macroscale polyaniline/modified fiber ball (PANI/m-FB) composite, and then its removal ability of Cr(VI) is investigated. The effects of different parameters such as contact time, pH value and initial concentration on Cr(VI) removal efficiency are discussed. The experimental results illustrate that the favorable pH value is 5.0 and the maximum removal capacity is measured to be 293.13 mg g−1. Besides, PANI/m-FB composites can be regenerated and reused after being treated with strong acid. The kinetic study indicates that the adsorption procedure is mainly controlled by chemical adsorption. More importantly, the macroscale of composites can avoid secondary pollution efficiently. Benefiting from the low cost, easy preparation in large scale, environmentally friendly, excellent recycling performance as well as high removal ability, PANI/m-FB composites exhibit a potential possibility to remove Cr(VI) from industrial waste water. Graphic Abstract The polyaniline (PANI) was coated on modified fiber ball (m-FB) to remove Cr(VI) in waste water, and this kind of PANI/m-FB composites can avoid secondary pollution efficiently due to its macrostructure. Furthermore, the removal capacity can reach to 291.13 mg/g and can be multiple reused.
