Treatment of Petrochemical Wastewater by the Green Algae
ABSTRACT:In recent years, cultures of algae were developed for both wastewater treatment and bio-fuel production. In this research, green microalgae Chlorella vulgaris were applied for bioremediation of an Iranian petrochemical wastewater samples. The efficiency of C. vulgaris and nonionic surfactants were examined in
Control Algae in Drinking Water Reservoirs. 1. Algae Problems in Drinking Water Removing algae from the water treatment plant is expensive and time consuming (e.g., the removal and cleaning of the sand filters). High in maintenance Reduced efficiency depending on the water quality Can control up to 90%
Enhanced algae removal by drinking water treatment
Overgrowing algae have brought negative impacts on daily production of water plants which are rarely eliminated by common methods. To efficiently remove algae from drinking water, a strengthening process or combined process of coagulant and chlorine, and with the dosage of potassium permanganate 0.3 mg L −1 is investigated on three selected water supply and purification plants during the
Microalgae have been proposed as an option for wastewater treatment since the 1960s, but still, this technology has not been expanded to an industrial scale. In this paper, the major factors limiting the performance of these systems are analysed. The composition of the wastewater is highly relevant, and especially the presence of pollutants such as heavy metals and emerging compounds.
Treatments of Industrials Wastewater by Using Microalgae
The soy sauce waste with green algae of Dundiella does not containing polyunsaturated fatty acid. The disruption the cells were easy and also doesn’t have a rigid cell. However, ethanol can be extracted easily. The decreasing of organic substance content the medium was noted so the treatment of waste water by using microalgae might be possible.
A New method was proposed for treating industrial heavy metal water treatment using algae. From the study the doubt arises whether pre-treatment is necessary to make algae as biosorbents. Harja et al. developed the oil extraction from algae waste which was activated by alkaline treatment to remove the cadmium II in batch and column studies
Water treatment chemicals - Lenntech
Algaecides Algaecides are chemicals that kill algae and blue or green algae, when they are added to water. Examples are copper sulphate, iron salts, rosin amine salts and benzalkonium chloride. Algaecides are effective against algae, but are not very usable for algal blooms for environmental reasons.
Loosely bound water is separated using low glass transition temperature hollow-fibre membranes, facilitating water transport in the vapour state rather than as a liquid and yielding high rejection of pathogens and some odorous volatile compounds. The water is recondensed and drains into a collection vessel for safe reuse at the household level.
Peracetic Acid Wastewater Disinfection - Enviro Tech
The cutting-edge solutions from Enviro Tech Chemical Services are improving the efficiency of water treatment processes worldwide. We set the standard for wastewater treatment. By developing and offering alternative chemistries, such as Peragreen WW peracetic acid (PAA), we are decreasing the disinfection cost of wastewater and ensuring that
Microalgae (including the cyanobacteria) are established commercial sources of high-value chemicals such as β-carotene, astaxanthin, docosahexaenoic acid, eicosahexaenoic acid, phycobilin pigments and algal extracts for use in cosmetics. Microalgae are also increasingly playing a role in cosmaceuticals, nutraceuticals and functional foods. In the last few years, there has been renewed
