Solid Solutions

Alfa Laval

The ALDRUM G3 drum thickener from Alfa Laval can reduce sludge volume by up to 90 percent. The mechanical thickener conveys polyelectrolyte treated sludge (flocculated sludge) through a slowly rotating drum filter. Sludge remains in the drum as water passes through the filter cloth. Optimal thickening is obtained by varying the feed rate, polymer type and dosage, drum speed and spraying interval. Water consumption is reduced by intermittent cleaning of the drum using potable water, final effluent or treated filtrate. Features include self-cleaning, enclosed design for an odorless work environment and choice of control panels and auxiliary equipment to meet specific needs. 866/253-2528; www.alfalaval.us/wastewater
