Improves waste treatment. A quick, efficient, and satisfactory way to upgrade tank based waste treatment operations is to install a Director II System. The Director II system is designed specifically for tank based waste treatment operations. As regulations have tightened, flow diversion has become an important boost to waste treatment efficiency.
Environetics’ Director II is custom manufactured to improve flow patterns in circular or rectangular tanks. The Director II flow diversion baffle system, effective in both new and in existing tanks, will give you the results you need.
Ideal for creating a staged treatment process in an existing single-stage operation. A multi-stage system can reduce power requirements and save energy costs. The Director II is a cost-effective upgrade for activated sludge systems.
Fixed flow diversion panels with an integrated top structural member designed especially for installation in concrete or steel waste treatment tanks.
Each tank baffle is custom designed for the specific tank and for the operating conditions. The
connection details vary depending on the section profile of the tank. Baffles are available in many
configurations. Specific details will be provided upon receiving the existing tank drawings and the
operating condition requirements.
The system is delivered in kit form including all hardware required to complete the installation.
The stainless steel support structure consists of specialized fittings attached to the walls and/or floor with expansion anchor bolts along with horizontal and vertical support pipes bolted to the fittings. The support pipes are cut and drilled on one end for the fitting fasteners and left long on the other end so they can be cut and drilled in the field to fit the tank exactly. Once the support structure has been fitted then the reinforced geomembrane baffle panels can be installed. The baffles are hung from the structure then secured to the concrete floor and walls with stainless steel batten and expansion anchor bolts. The batten material is shipped in 12-foot lengths and is cut to fit on site. A crane is not required.
The baffle can be moved in reverse order of the installation process. The wall and floor battens
would be removed first then the baffle would be removed from the top horizontal support. The
structural supports would be removed followed by removing the specialized fittings from the concrete tank. A new set of expansion anchor hardware would need to be installed at the new baffle location then the baffle could be installed in the new location.
No, the baffle is designed to divert flow therefore it is not designed to be used as a wall to hold back water. An opening in the baffle of 1 ft² per 300 GPM of peak flow is required. Differential head
pressure will void the warranty.
Manufacturing lead time is typically 6 to 8 weeks from receipt of approved submittals and verified field dimensions.
Each tank baffle is custom designed for the specific tank and for the operating conditions. Baffle
flow diversion configurations include: flow over, flow under, flow around, and flow through window. The peak flow rate for the tank will determine the correct flow opening size in the baffle curtain. The opening size must be at least 1 ft² per 300 gpm. The opening can be configured in a single opening or multiple openings.
Environetics uses Seaman Corporation 30 Mil XR-5 material which is designed specifically for
flow diversion baffle applications. XR-5 is the highest-strength and most chemically resistant
geomembrane on the market. Seaman Corporation claims 30 years of proven performance and they offer a 10-year weathering and chemical resistance warranty. Environetics supports the manufacturer’s performance claim. We have had XR-5 material in service in outdoor wastewater applications for 30 years without any material failures under normal operational conditions.
