CSO PROGRAMS WORK BEST WITH
SOLAR POWERED MIXING & DIFFUSED AERATION!

Studies from Clemson University Stormwater Pond Management use a "general rule of thumb" of a 1 cfm aeration diffuser which can adequately circulate and aerate a 1-2 acre stormwater retention pond.  

Thats exactly what our fixed G2V-STAR-120L and floating G2V-STAR-120F  units produce using only the sun!  Solar Powered Aerators using 12" EPDM self-cleaning, fine bubble tube membrane diffusers go anywhere and can be setup by anyone who can open the box in minutes!  Every G2V-STAR series model produces a minimum of 1 cfm/acre, 24/7, for Stormwater and Emergency Overflow Ponds using bottom mounted or anchored floating diffusers.

AERATION IS YOUR BEST STORMWATER MANAGEMENT PLAN.

las-cruces-dam-restoratio-reclaimed-wastewaterCirculating and aerating water in stormwater ponds provides several benefits.  A properly designed circulation system can prevent stratification, odor, and turnover fish-kill events.  Circulation systems also can help manage nutrients in the pond by balancing the trophic state and reducing nutrients available to algae and aquatic weeds.

By far, diffuser systems circulate water most efficiently and our 100% solar powered units never have a power bill. A general rule is that one diffuser unit can circulate a one to two acre pond.  Small or shallow ponds, 3-5 ft deep, typically require fewer diffusers as mixing and oxygen transfer by wind action alone disperses oxygen throughout the pond as is the design most municipal water treatment lagoons.  More diffusers may be needed in large irregularly shaped ponds for mixing deep water between pinch points.

For a 1-2 acre stormwater pond install one of our fixed mount G2V-STAR-120L or floating G2V-STAR-120F units.


POST AERATION INCREASES THE DISSOLVED OXYGEN TO REDUCE THE LOAD DOWNSTREAM.

Our EcoAerator  (G2V-STAR-120F) is also utilized to  immediately improve pond effluent or overflow 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 can be used.   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.  


COAL-ASH IMPOUNDMENT POND ALGAL PHYTOREMEDIATION,
DISSOLVED OXYGEN CONTROL, INSECT ABATEMENT, PHOSPHOROUS & ALGAE CONTROL

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.

ODOR CONTROL IN RETENTION PONDS

Odor control  aeration of ponds equates to 0.01 to 0.25 hp/106 gals. when using diffused air or  1 cfm of diffused air per surface acre vs. 1 hp water pumps to provide the same high oxygenation level.  Diffused air controls odor using 10% of the power needed by mechanical pumps to do the same job.  Its really pretty straight forward our 18 watt air compressor supported by 120 watt solar panel can provide the same high level of aeration as a 180 watt water circulator supported by three 120 watt solar panels.


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.
