WATER MANAGEMENT STREAMLINED STRAINING
How automated strainers can be paired with macerators to eliminate solids from slurries
I
n the power industry, industrial strainers are used to separate unwanted suspended solids from liquids, and slurries from boiler
water slag; or for filtering Bunker C fuel supplied to burners for power generation. However, conventional strainer methods can be unreliable and lead to extensive maintenance, particularly in cases where the debris or solids are of substantial size and there is a significant amount of suspended solids present. Fortunately, a novel blend of industrial wastewater technologies now allows for the efficient removal of solids without the need for extensive manual labour, worker exposure to messy or potentially hazardous substances, or constant maintenance. Specifically, the design involves a one-two punch combination of a macerator, which breaks down large solids into smaller fragments, and an automated scraper strainer flexible enough to efficiently filter out larger debris along with tiny particles. This innovative solution can

even accommodate high solids loading without clogging. The combination of these two established technologies is already being applied to some of the toughest, dirtiest straining applications in the industry including wastewater debris, power plant boiler water slag, asphalt transloading, and meat processing waste streams.

OVERCOMING TRADITIONAL LIMITATIONS Duplex strainers are often used in continuous flow processes that cannot
be shut down for cleaning purposes. Duplex basket strainers employ two distinct chambers that function independently. When one chamber needs cleaning, the flow is seamlessly diverted to the alternate chamber, enabling the removal and cleaning of the first basket. Cleaning is a messy, laborious process
that involves equalising pressure between the baskets, diverting flow to the off-line chamber, opening the cover, manually removing the clogged basket, and cleaning it before refitting the basket, ensuring the seal, and tightening the fasteners.
