  • The feasibility of flocculation in a storage sedimentation basin

    ABSTRACTFor the Flemish situation, storage sedimentation basins are one of the best 'end-of-pipe' solutions to reduce the impact of combined sewer overflows on the receiving waters. In some cases, when the spilled pollution load is too high, the settling efficiency of the basin has to be improved. Adding coagulants could be a reasonable alternative for building larger basins. To estimate the ...

  • Comparison of optional process configurations and operating conditions for ceramic membrane MF coupled with coagulation/flocculation pre-treatment for the removal of NOM in drinking water production

    The increase of Natural Organic Matter (NOM) in natural water sources, partly caused by progressing climate change issues, is a growing concern for drinking water production. In recent years, membrane technology like Reverse Osmosis (RO) or Nanofiltration (NF) has been successfully applied as a robust solution for NOM removal to produce potable water. However, coagulation/flocculation ...

  • 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 ...

  • Latex Paint Manufacturer-1

    The paint manufacturing facility was using 1 MGD of fresh water in the manufacturing process with a majority of the water being used for tank and pipe cleaning. As a cost cutting measure, the facility wanted to reduce the water consumption and reuse part, if not all of the wastewater. They tried several different combinations of coagulants and flocculants with limited success. Integrated ...

  • Methodology for sampling drinking water discolouration loose deposits at low velocities

    The occurrence of discoloured water at the tap is one of the most frequent reasons for customers to complain. Water discolouration arises from the re-suspension of loose deposits (LD) that accumulate in drinking water pipes, due to velocity increase. Because of its typical brownish/reddish colour, discoloured water is traditionally perceived as a consequence of cast-iron pipe corrosion, even in ...

  • Case Study: Iron Foundry

    The foundry recycles engine blocks to make iron pipe. They have a 350-gpm closed loop water reuse system that is used to cool the molds as part of the manufacturing process. The facility was using a coagulant and a flocculant to try and reduce the solids carryover from their clarifier. The solids in the reuse water were building up in their system filters causing intermittent downtime (downtime ...

  • Fracking wastewater treatment at collection facility

    Abstract Engineering company operates a wastewater collection and treatment facility for their clients in Myton, Utah. The facility receives fracking and produced wastewater from various pumping stations, and then treats the water for disposal at the injection well located on site. Electrocoagulation followed by two clarifiers and 5 micron filter was used. Since many particles float or just ...

  • 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 ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...
