British Columbia, Canada, August 7, 2019-Polymers have been used for many decades for the treatment of sediments as it helps to improve the dewatering step and results in high solid content and clear-water release. The use of polymers is not something that will stop anytime soon given its immense advantages in the wastewater drainage and management process. There are many factors that affect the choice of polymers for use in the dredging process. They include:

The Required Results

Every project has its unique specifications that influence the type of polymer that is selected. For instance, Wastewaters derived from industries such as mining, textile, and pulp and paper tend to have a relatively constant composition and this makes the choice of polymer used uniform. However, in dredging projects where the sediments are pumped hydraulically and then sent directly without the use of holding tanks, there may be high fluctuations in sediment composition because of water content and the way equipment is operated by the dredge manager. As a result, specialized monitoring equipment is necessary to adjust the ratio of polymer dosage to the sediment slurry composition.

Water Composition

Water may contain mineral particles or absorbed pollutants that have not been eliminated by previous separation steps. The water may also have organic compounds from natural processes or human activities. The mineral to organic ratio is an important parameter that will determine the charge density and the type of Dry Polymer used. The selection and effect of the polymer may also be influenced by the presence of salt and iron levels in the water.

Dewatering Equipment

Dewatering equipment has a unique mechanical effect that influences the selection of polymer. For instance, mechanical effects may appear during the preparation step where the use of shearing pumps tends to breakdown the structure of the polymer and this reduces its efficiency. Shearing can also impact the flocs that are formed and this may result in flocs that are not resistant enough to hold their structure or settle as quickly are required. Geotextile bags and centrifuges will also have varying mechanical effects on the polymer used.

The prevalence of polymer used in dredging projects is attributed to the lack of space, lack of time for sediment dewatering and the stringent regulations on discharged water. With the use of polymers, industries and local authorities enjoy lower turbidity in the discharged water, shorter drying time, increased water quality, and reduced land surface used for sludge treatment.
