Polypropylene media Biopack 180 mm Bacterial Filter

Advantages:

• precise design;
• resistant to UV degradation;
• durable construction;
• Non-toxic, lightweight, UV resistant material.

Polypropylene nozzle Biopack SF # 30 works successfully in more than 100 bacterial filters. With over 300 mixing and redistribution points for both air and water per cubic foot of media, Bio-PAC is capable of redistributing wastewater every 2 inches of media depth. This feature makes Bio-PAC ideal for shallow jet filters.

Biopack SF #30 is also widely used in ascending anaerobic and aerobic submerged bed reactors. Since the carrier floats, the use of a bottom drain support is eliminated. In addition, Biopack's unique form serves as a defoamer when installed in anaerobic reactors.

Media Specifications:

• Surface area 30 ft2/ft3 void ratio 95% made from UV stabilized polypropylene.
• Low installation cost is great for BOD reduction or nitrification.
• Low minimum wetting rate, 150 gpd/ft2 for layer depths up to 30 ft.
• Special surface design, stronger biofilm growth ability.
• Large specific surface area, high voidage, the greater the periphyton biomass.
• Unique structure and shape design according to fluid mechanics, strong three-dimensional flow dynamics in water.
• With the addition of hydrophilic groups and other trace elements, the biofilm formation time is only 3-15 days.
• Excellent impact strength, high gas shear capacity.
• Without any holder, easy to solidify, saving energy and space.
