Second, BOD in waters, resulting from CSO "wet weather" inputs of organic and fecal material, restricts oxygen consumption by entire ecosystems and may cause specie die-off, such as fish. The solution is Aeration & Circulation. Our 100% Solar Powered Aerators circulate, mix, recycle, and aerate with No-Grid connections and no power bills. Reconciliation Ecology Technologies at work!
According to studies at Clemson University Stormwater Pond Management a general rule of thumb is that a 0.25-1 cfm medium bubble diffuser can adequately circulate and aerate a 1-2 acre retention pond. Thats exactly what our floatingG2V-STAR-120F and EKBS-12 Solar Powered Aerators produce using 3-24" EPDM self-cleaning, fine bubble disc and tube membrane diffusers. PEC recommends a minimum of 1 cfm/acre for Stormwater and Emergency Overflow Response Ponds and a maximum of 5 cfm/acre to minimize turbidity and enhance TSS reduction in non-aerated settling zones.
POST AERATION INCREASES THE DISSOLVED OXYGEN TO REDUCE THE LOAD DOWNSTREAM.
Our EcoAerator a.k.a. (G2V-STAR-120F)is also utilized to immediately improve effluent dissolved oxygen levels.
Stormwater and Wastewater lagoon effluent oxygen demands should be measured, but if they cannot be easily measured, an oxygen uptake rate of 0.1 lbs O2 /hour/ 1000 gallons is recommended. Our 1-4 cfm of fine bubble EcoAerators can easily handle wastewater oxygen uptake rates of 0.8/ lbs O2/hour/ 1000 gallons or 4 times the recommended typical wastewater pond effluent application rate needed to reach 50-100% of saturation with 30-60 minutes of detention time.
Algae control and mosquito abatement in man made and natural ponds has been studied worldwide. Most recently studies have focused on stormwater and coal-ash retention ponds as a direct function of aeration intensity to stabilize dissolved oxygen levels, prevent mosquito breeding, control algae sporulation, and prevent anaerobic odors. PEC recommends a minimum of one G2V-STAR or floating Eco-Aerator version of our solar aerator per surface acre for dissolved oxygen control. Our floating airlift aerator draft tube draws water from any depth adds oxygen and mixing inside an expandable 4" diameter tube. This prevents disturbing any bottom sediment or clay layers.
Algae-out with "Fish-grow" are algae enzymes that work with aeration to improve water quality and reduce algae buildup.
*There is no max depth when using a PEC airlift aerator, because it is a floating tube. Simply increase the length of the draft tube to vacuum water from any desired aeration depth up to 20 feet deep. The draft tube standard discharge flow is omnidirectional
**The standard Eco-Aerator mounts wet or dry and is designed for stormwater, effluent retention ponds, and dugouts.
