Understanding the Many Types of Macerators



March 18th, 2014

Defining Macerators

Macerators are a form of pump that includes a series of internal knives or blades that are designed to chop up solids into slurry for easier pumping. There are countless applications for Macerators, and they can be found in both home and industrial capacities.

Types of Macerators

It’s easy to find places where Macerators are in use on a daily basis. Within your own kitchen, you’ll have macerators serving as your garbage disposal and your food processor. Homes with low water pressure will often feature macerating toilets to convert solid waste into liquid solutions that can much more easily pass through plumbing systems.

Many boats will also feature macerators to convert solid waste into a liquid before jettisoning the waste into the surrounding water. Sewage treatment facilities frequently rely on macerators to make the mix of solid and liquid waste safer for all of the other pumps in the system.

Many meat, poultry, and fish processing centers use macerators to grind down the solid waste into a form that can be quickly washed away from the plant. Food processing plants will often create a protein-rich by-product of wastes through maceration that can be used to feed livestock elsewhere.

Benefits and Costs

There are a number of benefits to using maceration. Although pipes and pumps can look quite strong, many of them are easily damaged or clogged when large solids are sent through them whole. Maceration protects plumbing systems from heavy damage and inefficiency, which means that they end up saving individuals and companies thousands of dollars a year in repairs and maintenance.

The costs to purchase macerating pumps will vary depending on the intended use for the pumps. Macerating toilets, for instance, can run under $1,000, and garbage disposals can be had for well under $200. On the other hand, industrial macerators and those intended for large-scale sewage treatment will cost significantly more. When you consider the savings that these macerators provide, however, the cost will be well worth it.

Latest Developments in Macerators

While the general mechanism of the macerator has remained unchanged since it was first developed in the 1950s, there have been a few changes in recent years that have allowed for customized implementation. Macerators today can often come with a double set of blades that can each be operated independently, allowing for a much more precise chopping action. This is especially helpful in food production and meat processing.
