The Wisconsin Sustainable Business Council recently recognized Nelson and Pade with the Sustainable Product of the Year Award for small business. Nelson and Pade’s Clear Flow Aquaponic Systems® with ZDEP™ are highly efficient and continually produce fresh fish and vegetables year-round. The ZDEP (near Zero Discharge / Extra Production) eliminates a waste-water stream from the system while increasing vegetable production. The clean water leaving the ZDEP™ is used to refresh system water, reducing overall water usage while growing more plants in the system, and it generates an additional all-natural fertilizer stream that is used to grow a variety of plants in living filter beds. With more than 20 years of experience with aquaponic systems, Nelson and Pade is a global leader in the aquaponics industry, offering complete Clear Flow Aquaponic Systems with ZDEP, the Aquaponics Master Class and the Nelson and Pade Grower Support Program.
