Testing Direct Filtration for the Treatment of High‐Turbidity Water
Pilot‐testing was undertaken by the Greater Vancouver (B.C.) Water District to determine the feasibility of using direct filtration for treating turbid water. Because episodes of natural high turbidity tended to be of short duration, turbidity spiking was included in the investigation. Results showed that turbid water could be treated successfully with direct filtration when a deep‐bed monomedium filter was used; a shallower dual‐media filter was not acceptable. Even with a high‐turbidity raw water, turbidity and production goals were met. Determining the appropriate dosage of filter aid was a key factor in meeting the performance goals.
