Algae in water treatment - Degremont
Photosynthetic algae (assimilation of CO 2, N and P) can be used in water treatment which supposes the pre-treatment of water to eliminate suspended matter and degradeable carbon and consequently encourage a good diffusion of light radiation which is necessary for photosynthesis. To do this, the use of algae in water treatment is limited to
The algae also reduces the amount of light that is able to penetrate the water, which can affect the growth of other aquatic plants. With the continuation of wastewater pollution in China, the precious wetland habitat is destroyed affecting many animals inhabiting the ecosystem. Waste Water Treatment Plants
Nitrogen transformation and wastewater treatment
Nitrogen transformation and wastewater treatment efficiency in algae-based and duckweed-based stabilization ponds Conference Paper (PDF Available) 路 May 2000 with 146 Reads How we measure 'reads'
China needs to develop its wastewater sector to tackle worsening water pollution. Efforts to improve wastewater treatment infrastructure are obvious: investment in wastewater treatment stood at RMB14 billion in 2012 1 and under the 12 th Five-Year Plan (12FYP), total investment in wastewater treatment and recycling infrastructure in urban areas is expected to reach RMB430 billion, a 20%
Study on Treatment of Domestic Sewage by Algae Biofilm
The algae biofilm process was used to treat domestic sewage.The removal effects of nitrogen and phosphorus were investigated emphatically.The results show that in the static tests,the removal effects of nitrogen and phosphorus in the algae biofilm process are

Wastewater use in algae production - Aquatic Biosystems
Microalgae feedstock production can be integrated with wastewater and industrial sources of carbon dioxide. This study reviews the literature on algae grown on wastewater and includes a preliminary analysis of algal production based on anaerobic digestion sludge centrate from the Howard F. Curren Advanced Wastewater Treatment Plant (HFC AWTP) in Tampa, Florida and secondary effluent from the
This paper introduces the up-to-date zero liquid discharge(ZLD) technology which have been put into use in industry,generalizes the normal compositions of ZLD system,and describes the pre-treatment,thermal treatment,the final solid waste treatment and unique
Commonly Used Algae Strains for Waste Water Treatment
Algae in wastewater range in size from tiny single cells to branched forms of visible length. Unicellular green algae such as Chlorella and Scenedesmus have been widely used in waste-water treatment because they often colonize the ponds naturally, and they have fast growth rates and high nutrient uptake capabilities per unit biomass due to their small sizeClasses of algae that are commonly

Wastewater Pollution in China - University of California
The algae also reduces the amount of light that is able to penetrate the water, which can affect the growth of other aquatic plants. With the continuation of wastewater pollution in China, the precious wetland habitat is destroyed affecting many animals inhabiting the ecosystem. Waste Water Treatment Plants
Algae have demonstrated the ability to naturally colonize low-nutrient effluent water in a wetland treatment system utilized by the City of Lakeland. The results from these experiments show that the algae grown in high strength wastewater from the HFC AWTP are light-limited when cultivated indoor since more than 50% of the outdoor illumination
- How much urban wastewater is treated in Thailand?
- However, only small portion of total urban wastewater generated in Thailand is treated. Twenty-nine urban wastewater collection and treatment plants have been constructed in 24 municipalities. However, the facilities can serve only 400,000 m3/day or about 2.3 million (approximately 10 %) of urban population.
- How is industrial laundry wastewater treated?
- Several studies have reported on the treatment of industrial laundry wastewater using a wide range of techniques including biological, chemical, and advanced oxidation processes. Frequently, a combination of techniques is needed to achieve the desired water quality.
- What methods are used in laundry wastewater treatment?
- Several techniques can be employed in laundry wastewater treatment, including coagulation, filtration, biological reactors, adsorption, or advanced oxidation processes. Frequently, a combination of the mentioned processes is needed to meet the desired water quality standards.
- Why are waste management projects delayed in Thailand?
- Public participation is being strong against waste management projects in Thailand. The public is generally received effective communication concerning the risk from waste discharges. Thus, many projects have been delay due to the lack of enough information and ignorance of the steps of public involvement.
