Traditional and novel reservoir management techniques to enhance water quality for subsequent potable water treatment
Thames Water treats approximately 2800Ml/d of water originating mainly from the lowland rivers Thames and Lee for supply to over 7.3 million customers, principally in the cities of London and Oxford. Traditionally, for London, water treatment has consisted of abstraction (pumping water from the rivers Thames and Lee), theoretical storage for 30–80 days in deep reservoirs, two stage filtration ...

The development and application of the hybrid centrifugal - dissolved air flotation system for wastewater treatment
Abstract Solid/liquid separations are integral part of any wastewater treatment system. Particles heavier than water are commonly separated in sedimentation clarifiers. On the other hand, particles with densities lower than that of water are most often separated with flotation systems. This manuscript describes the development of hybrid centrifugal - dissolved air flotation system. The system was ...

Monitoring and Treatment of Selected Nanoparticles
With their increasing use, nanoparticles will become concentrated in urban effluents in the future. Both adequate monitoring methods and water treatment technologies will be necessary to assess and avoid consumer exposure. This paper reports results in these two challenging areas for both organic and inorganic nanoparticles. Treatment experiments indicate that lamellar settling is better adapted ...

Industrial Laundry-4
This facility washes heavy industrial rags and towels from furniture manufacturing, ink roll towels, automotive and other operations. The wastewater process uses flow equalization for the 60,000 gpd flow, pH adjustment with sulfuric acid, coagulation, metal precipitation, flocculation followed by dissolved air flotation. The facility had difficulty meeting the effluent metals for Copper (1.5 ppm) ...

What Is Dissolved Air Flotation?
In dissolved air flotation (DAF), fine bubbles attach themselves to suspended matter in a liquid, floating them to the surface for removal Dissolved air flotation (DAF) is a water treatment technology often used for the pretreatment of source water, but what exactly does it entail and how does it fit in with other technologies? DAF is a type of coagulation-flocculation technology typically ...

Flotation of algae for water reuse and biomass production: role of zeta potential and surfactant to separate algal particles
The effect of chemical coagulation and biological auto-flocculation relative to zeta potential was examined to compare flotation and sedimentation separation processes for algae harvesting. Experiments revealed that microalgae separation is related to auto-flocculation of Anabaena spp. and requires chemical coagulation for the whole period of microalgae cultivation. In addition, microalgae ...

Case study: pretreatment of challenging pork rinds manufacturing wastewater
Abstract Problem: Gaytan Foods facilities in City of Industry (Los Angeles, CA) manufacture pickled pork rinds, pickled pig feet and “cheese” puffs. The resulting wastewater is loaded with FOG’s, proteins and salts. Wastewater varies hourly and daily. Drastic changes in amount and type of contaminants occur (two orders of magnitude). During some hours wastewater is loaded with ...

Case Study: Heavy Industrial Laundry
This facility washes heavily soiled towels from the ink printer and furniture polishing industries. The wastewater generated is very concentrated with metals and hydrocarbons making it difficult to treat in their DAF pretreatment system. The facility was using conventional chemistry with sulfuric acid, organic/inorganic coagulant, metal precipitant,flocculant, and Harborlite (filter press ...

Wastewater-Primary Treatment
Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...
