For many industrial wastewater treatment facilities, sludge accounts for as much as 30-40% of capital costs and about 50% for the operating costs due to the complex nature of processes involved to curb by-product waste. For this reason, many water treatment plants focus on improved quality within their operations of sludge handling and mixing equipment selection. Let’s look at how a sludge mixer can help.
The Komax Hi-Pass™ Sludge Mixer design is to achieve polymer savings in excess of 25%. It does this by effectively mixing polymer solution into sludge flows prior to the dewatering process. Here is a look into how a newer technology design improves water treatment plants’ problems and savings in one.
The Komax Hi-Pass™ sludge mixer design is to be extremely resistant to fouling or clogging. The edges of the element sets are smoothly contoured with a large radius for high fouling duty. The basis for the mixer design is a set of right rotation elements. It is followed by a set of left rotation elements set at 90 degrees from each other.
This is a non-clogging design as the municipal sludges contain solid and fibrous materials of sufficient quantities and types to accumulate and cause fouling or plugging conditions in standard mixers.
The Komax Hi-Pass™ sludge mixer can efficiently perform pressure-sensitive applications. It is specifically capable of handling and mixing municipal sludges with solids up to 5%, and of passing individual solid items with a nominal major diameter up to 25% that of the mixer.
It prevents the “stapling” of stringy materials in the flow and has a relatively lower pressure drop than that of a traditional mixer.
The injector manifold of the mixer design is to present the diluted polymer solution to the sludge flow for optimum efficiency. Better dispersion of the small amount of solution through the sludge mixing elements is achievable.
The Komax Hi-Pass™ sludge mixer will reduce polymer consumption and costs and will produce dryer cake solids in dewatering operations. It is particularly suited for use on the feed line to devices. For example belt fiber presses, plate filter presses, gravity belt thickeners, centrifuges, and pressure or vacuum filters.
In addition to the wastewater industry, there are several that find the sludge mixer to give the best mixing results
They also use Hi-Pass™ mixing elements in various other Komax products where high fouling can occur, or large debris needs to pass through. Klean-Wall Heat Exchanger and Open Channel Mixers are specifically two additional units that use the Hi-Pass™ mixing elements.
