Floating Baffles & Pond Curtain Systems — HDPE Flow Control for Wastewater & Stormwater Treatment
AWTT floating curtain baffles transform large open ponds into engineered treatment systems. Modular HDPE curtain panels divide lagoons into sequential flow-controlled cells — eliminating short-circuiting, maximizing retention time, and improving overall treatment performance by up to 30%.

The Problem: Hydraulic Short-Circuiting Wastes Treatment Capacity
In large treatment ponds and lagoons, incoming wastewater takes the path of least resistance — flowing directly from the inlet to the outlet without adequate treatment contact time. This hydraulic short-circuiting means that a pond designed for 30-day retention may achieve only 5–10 days of actual treatment, resulting in permit violations, poor effluent quality, and wasted infrastructure investment.
The same problem affects odor control, chemical treatment efficiency, and settling performance. Without directed flow, treatment is uneven, chemical dosing is inefficient, and odor hotspots form near the inlet where high-strength influent concentrates.
The Solution: AWTT Floating Baffles Force Engineered Flow Paths
AWTT floating curtain baffles are installed perpendicular to the flow direction, dividing the pond into a series of sequential treatment cells. Wastewater must flow through each cell in sequence — maximizing hydraulic retention time, equalizing treatment loading, and eliminating dead zones.
Each baffle system is custom-designed to the pond's geometry, depth, and hydraulic loading. HDPE flotation booms keep the curtain at the surface while bottom ballast chains maintain vertical orientation. The modular panel design allows field adjustment as conditions change — no pond modification or draining required.

Key Benefits of AWTT Floating Baffles
Engineering-grade flow control that maximizes the return on your existing pond infrastructure.
Eliminates Hydraulic Short-Circuiting
Forces influent to follow the designed flow path through treatment cells, preventing untreated water from bypassing the pond and reaching the outlet.
Maximizes Hydraulic Retention Time
Longer, more uniform flow paths ensure full contact time between wastewater and treatment bacteria, improving BOD and TSS removal efficiency.
Zone Separation for Multi-Stage Treatment
Divide large ponds into sequential treatment zones — aerobic, anoxic, and settling cells — without separate infrastructure.
Odor Containment Zones
Baffle walls can isolate high-odor zones from low-odor areas, enabling targeted odor control or cover placement over the most problematic sections.
DOT Turbidity Curtain Systems
Federal and state DOT-compliant silt curtains for construction site stormwater compliance, dredging operations, and shoreline protection.
Modular & Adjustable
Panels are connected in the field to span any pond width. Adjustable mooring allows repositioning as pond conditions or treatment requirements change.
Floating Baffle Applications
Deployed across municipal, industrial, and agricultural treatment systems throughout North America.
Municipal Wastewater Treatment
Convert facultative ponds into engineered plug-flow treatment systems.
Agricultural Lagoon Management
Improve manure lagoon treatment efficiency and reduce nutrient loading.
Industrial Effluent Treatment
Zone separation for multi-stage industrial wastewater pre-treatment.
DOT Construction Site Compliance
State and federal DOT turbidity curtain compliance for dewatering and excavation.
Mining Decant Pond Management
Flow management and zone separation in heap leach and tailings ponds.
Stormwater Retention Basins
Direct stormwater flow to maximize sedimentation and infiltration contact time.
