Water Aerator Systems for Dams, Lagoons and Wastewater
Improve oxygen transfer, water circulation and treatment performance with a safer, bank-mounted water aerator system.
EchoStorm Water Aerators Across Australia
Hydro Innovations supplies Gorman-Rupp EchoStorm water aerators for industrial, municipal and wastewater applications across Australia. These Venturi aeration systems improve dissolved oxygen and mixing while keeping the pump and aerator accessible from the bank. Water is drawn from the dam, lagoon or treatment pond and pumped under pressure through the EchoStorm aerator. The Venturi effect draws atmospheric air into the system, where it mixes with the water before being discharged back into the water body. Unlike floating or submerged aerators, the bank-mounted EchoStorm can eliminate the need for boats, cranes, floating walkways and risky over-water maintenance. Speak with Hydro Innovations about your water aeration requirements.
Water Aeration for Blue-Green Algae Control
Blue-green algae can become a serious issue in stagnant or poorly circulated lakes, dams and wastewater ponds. EchoStorm does more than introduce oxygen: its mixing and conditioning action can rupture the buoyancy vacuoles within blue-green algae cells, causing affected algae to sink and reducing access to the sunlight required for continued growth. The system also circulates the water body, reduces stagnant zones and strips carbon dioxide, providing a practical non-chemical approach to blue-green algae management across council lakes, industrial ponds, food-processing lagoons, agricultural dams, effluent ponds, municipal lagoons, recreational lakes and mine-water ponds.
Proven algae reduction at Talloman: Craig Mostyn Group’s Talloman protein-rendering facility was experiencing blue-green algae in a wastewater treatment pond. Hydro Innovations recommended a 100mm EchoStorm system powered by a Gorman-Rupp self-priming centrifugal pump. Total algae taxa fell from approximately 217,000 cells per millilitre to 6,630 in less than two months—a reduction of about 97%. The team also gained a system that could be monitored and maintained safely from the bank.
Low dissolved oxygen can restrict the aerobic biological processes used to break down organic matter in wastewater. A correctly configured EchoStorm can support aerobic bacteria and improve conditions where operators are targeting BOD, COD, TKN, ammonia and nitrogen, organic loading, odour, septic conditions or poor biological treatment performance. Its discharge also conditions the flow and breaks organic matter into smaller particles, making it more available to the biological treatment process.
Bega Cheese reduces COD by 50%: At Bega Cheese’s Strathmerton facility, Hydro Innovations replaced ageing surface aerators in a 45-megalitre wastewater lagoon with a 150mm bank-mounted Venturi aerator and Gorman-Rupp self-priming pump. Operators recorded increasing dissolved oxygen, a 50% reduction in COD and an odour-free lagoon, while monitoring and maintenance could be completed safely from the bank.
Stagnant municipal lakes and ponds can experience low dissolved oxygen, thermal stratification, algae growth, odour and poor circulation. A bank-mounted water aerator draws water from selected areas, introduces atmospheric oxygen and returns oxygenated water at a velocity that encourages circulation.
EchoStorm may assist with lake and pond destratification, blue-green algae control, reduction of stagnant areas, improved dissolved oxygen, odour management, water circulation and safer access for council maintenance teams.
Multiple EchoStorm units can be configured where larger water bodies require additional oxygen transfer or broader mixing coverage. Hydro Innovations assesses lake volume, depth, access and water-quality objectives before recommending a system.
Safer bank-mounted access keeps the pump and aerator on solid ground. EchoStorm has no moving parts inside the Venturi aerator, while high-velocity discharge supports oxygen transfer, thorough mixing and fewer stagnant dead zones. Routine maintenance is concentrated on the accessible Gorman-Rupp pump, without retrieving submerged equipment or using boats and cranes.
EchoStorm aerators are available in 50mm, 80mm, 100mm and 150mm sizes. Multiple units can meet larger oxygen-transfer or circulation requirements, and the system can be paired with a Gorman-Rupp solids-handling self-priming pump selected for the liquid, flow, solids and site conditions.
Choosing the right water aerator requires more than pond surface area. Hydro Innovations considers water volume and depth, dissolved oxygen, BOD, COD, TKN or ammonia targets, inflow and organic loading, algae concentration, circulation, power, suction lift, pipework, solids, operating hours, maintenance access and site safety before recommending an EchoStorm size, pump and discharge arrangement.
EchoStorm systems support food and beverage wastewater, municipal and industrial treatment lagoons, dams and storage ponds, oxidation ditches and treatment basins, sludge digestion and septage treatment, plus leachate and mine-water applications.
They can improve dissolved oxygen, water movement, biological treatment conditions, odour control and circulation before later treatment or discharge.
Frequently Asked Questions
What does a water aerator do?
A water aerator introduces air or oxygen into water while helping circulate and mix the water body. Depending on the application, this may improve dissolved oxygen, reduce stagnant areas, support biological wastewater treatment and assist with algae or odour management.
Can a water aerator help control blue-green algae?
The EchoStorm’s mixing and conditioning action can rupture the buoyancy vacuoles that allow blue-green algae to remain near the water’s surface. Affected cells sink and lose access to the sunlight required for growth. Results depend on the water body, algae concentration, operating conditions and system configuration.
Is EchoStorm a floating water aerator?
No. EchoStorm is a bank-mounted Venturi aeration system. The aerator and self-priming pump remain accessible beside the dam, pond or lagoon.
Does the EchoStorm aerator have moving parts?
The Venturi aerator itself has no moving parts. The system uses a Gorman-Rupp self-priming centrifugal pump to move water through the aerator.
Can EchoStorm reduce BOD and COD?
Introducing dissolved oxygen can support aerobic bacteria responsible for breaking down organic matter. EchoStorm systems may therefore form part of a wastewater treatment strategy targeting BOD and COD reduction. Actual results depend on wastewater characteristics, loading and overall treatment design.
Is the system suitable for council lakes?
EchoStorm can be configured for lake destratification, circulation, algae management and oxygen transfer. Hydro Innovations can assess the lake volume, depth, access and water-quality objectives before recommending a system.
What sizes are available?
EchoStorm water aerators are available in nominal sizes of 50mm, 80mm, 100mm and 150mm. Multiple units can be installed for larger applications.
How much maintenance is required?
Because the EchoStorm Venturi aerator has no moving parts, routine mechanical maintenance is concentrated on the Gorman-Rupp pump. The bank-mounted arrangement makes the equipment easier to reach for inspections and servicing.
