Food such as rise, wheat, pulses and potatoes contain large quantities of starch. If large quantities of these ingredients are processed in large catering kitchens or in the food industry (potato processing companies such as crisp production, frying factories or canneries), the wastewater must be treated accordingly. The ACO product range includes starch separators for installation in the ground and for freestanding (outdoor?) installation. Starch is insoluble in water and exists as particles. These are heavier than water and settle in the bottom part of the separator, in the starch collection chamber. The potato starch separator is available with hydromechanical high-pressure internal cleaning (treatment?), a disposal pump and direct extraction. Disposal, cleaning (treatment)? and filling are then possible without odour nuisance.
