Decanter centrifuge reduces biosolids disposal costs
Problem
Hollandia Dairy in Southern California was paying to transport 25,000 pounds of wastewater biosolids a day.
Solution
An Alfa Laval ALDEC 20 decanter centrifuge now concentrates solids from moving bed biofilm reactor (MBBR) wastewater before further processing into Class A biosolids. The skid-mounted unit was selected as a tried and tested technology; it includes the company’s Connectivity remote monitoring support.
Result
The decanter handles 3,000 gpd of wastewater and achieved the expected results. With the additional processing, the dairy now trucks away only a small amount of Class A biosolids that can be used
