Slow sand filtration is a type of centralised or semi-centralised water purification system. A well-designed and properly maintained slow sand filter (SSF) effectively removes turbidity and pathogenic organisms through various biological, physical and chemical processes in a single treatment step.
Wash water troughs, large enough to collect backwash water without flooding. The troughs are spaced so that the horizontal travel of backwash water does not exceed 3-3 ft. In conventional sand bed units, wash troughs are placed approximately 2 ft above the filter surface.
Water System Design Manual DOH Pub 331-123 Revised June 2020. Acknowledgments This is the fourth edition of the Water System Design Manual. Many Department of Health (DOH) employees provided valuable insights and suggestions to this publication.
Aug 12, 1998· The filter operates at a design velocity of 6 m 3 m 2 h −1 and requires cleaning with a combined air scour and water backwash which results in a water recovery across the bed of 98–99%. Finally the flow passes through a 5 μm cartridge filter to remove any gross solids and filter grains that might pass through the bed.

Sep 10, 2015· Washing sand and aggregate results in the discharge of dirty water from wet screening decks, sand screws or sand classifiers. The wastewater typically carries fines out to a series of settling ponds. While this is the most common method of treating wash water .
The art and science of analyzing and improving your dewatering, classification or thickening process is deeply rooted in PHOENIX's DNA. We are a dewatering, thickening and classification process technology provider for minerals mining, construction aggregate, industrial waste processing and municipal wastewater treatment.
Rotary Scrubbers. Rotary Scrubbers are used to wash crushed rock, ore, sand, gravel, construction aggregates and oil sands. They are high-capacity, high-retention machines that can accept large-sized feed material and are used primarily to remove water-soluble clays, deleterious materials and coatings providing a cleaner product
Mar 03, 2014· Our oil water separators have been specially developed for treating wash water from commercial vehicle washing operations. Used in a variety of applications, our vehicle washing oil water separator systems will remove 99.9% of free and dispersed non-emulsified oil droplets in the wash water with discharge to the sewer or a treatment plant.

We have systems that recycle 100% of all wash water captured as well as a range of approved and compliant pre-discharge systems.
The sand is freed from clay and organic impurities by log washers or rotary scrubbers. After scrubbing, the sand typically is sized by water classification. Wet and dry screening is rarely used to size the sand. After classification, the sand is dewatered using screws, separatory cones, or
PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the process.
