​​Agricultural Material Processing Facility**


This facility has wastewater with solids which are difficult to settle. The solids overload the treatment facility resulting in high BOD and solids in the effluent. High Speed Magnetic Clarification was able to reduce these solids from over 5,000 mg/l to 55 mg/l. The settling rate of the sludge also increased greatly and a more compact sludge was produced.

Removing Phosphorous from Process Water*


Industrial Client Removing Phosphorus from Process Water so it can be used as Cooling Tower Makeup Water*. Phosphorus was removed from pharmaceutical process water in the cooling towers by high speed magnetic clarification.  Water which would normally be discharged is treated and sent to the cooling towers as makeup water. Purchase of new water is reduced and costs for discharge are eliminated. Savings of over $200,000 USD annually by recycling the water.

Town of Pittsboro Municipal Wastewater Treatment Plant*


Removed suspended solids and phosphorus from final effluent operating side by side with existing sand filters. Produced better quality water than sand filters. Reduced phosphorus from ~ 3 mg/l to ~0.3 mg/l.

"The Magnetic Separator/Clarifier was our lowest cost option to meet metal discharge limits."

Town of Cary Wastewater Treatment Plant**


The goal of this work was to increase the settling rate of the activated sludge. The activated sludge MLSS was 2,740 mg/l. Magnetite was added with a cationic polyacrylamide flocculating polymer at a rate to ensure good attachment of the activated sludge particles to the magnetite.


The clarified effluent of the MSS treated activated sludge was in the range of 12 to 19 mg/l indicating good clarification. The sludge height over time was measured for both MSS treated and untreated activated sludges. Settling rates were measured for four concentrations made by serial dilution.


For all concentrations, the MSS treated activated sludge settled more rapidly than the activated sludge without treatment. At MLSS concentrations of 1,096 mg/l the MSS sludge settled approximately 574% faster. However, at the highest concentration tested of 2,740 mg/l the MSS sludge settled 1,574% faster or over fifteen times faster.

Pittsboro Plant**


The goal of this work was to increase the settling rate of the activated sludge. The activated sludge MLSSwas 2,010 mg/l. Magnetite was added with a cationic polyacrylamide flocculating polymer at a rate to ensure good attachment of the activated sludge particles to the magnetite. The clarified effluent of both the MSS treated and untreated activated sludge was in the range of 4 to 7 mg/l indicating good clarification.


The sludge height over time was measured for both MSS treated and untreated activated sludges. Settling rates were measured for four concentrations made by serial dilution. For all concentrations, the MSS treated activated sludge settled more rapidly than the activated sludge without treatment. At MLSS concentrations of 402 mg/l the MSS sludge settled approximately 67% faster. However, at the highest concentration tested of 2,010 mg/l the MSS sludge settled 786% faster or almost eight times as quickly. 

Oil Well Production Water*

(Confidential Client)


Treated slick water with the goal of removing suspended solids and selective dissolved metals.  Successfully removed both the solids and metals such that the water can be recused

"By far the simplest, and most cost effective system I have seen."

Industrial Pond Algae Removal*


Pond had high algae growth which was removed in the High Speed Magnetic Clarifier. Influent suspended solids of 270 mg/l was reduced to 20 mg/l representing 93% removal.
