Impressive Oil Water Separation

Scenario

The water sample from a CUDD Energy oil field site was treated for solids reduction, BOD reduction, metals and dissolved metals.

Metal Machining Wastewater Case Study

The table below shows the results of the analytical, with the untreated water sample and sample treated with Floccin TR-1™. The jar tests below show the effect of the Floccin TR-1™.

Conclusion

The treatability shows the high removal rate for heavy metals, minimal increase in EC/TDS as shown in the anions/cations and high removal of particulate solids in the form of suspended solids. Increases are shown as negative percent reductions and are the contribution of the Floccin. The minimal increase is less than conventional chemistry. There was not enough sample to test for Total Petroleum hydrocarbons, COD, BOD or any bacterial colony counts.

Teflon (PTFE) Coating Operation

A manufacturer of Teflon coated products contacted Integrated Engineers seeking a solution to their wastewater problems. They were generating 3,500 gallons of wastewater each week that had to be hauled off site. They were looking for a method to treat this water and reuse the treated water within their facility. Integrated Engineers performed treat ability studies of the wastewater and identified the FloccinAgentTM that would meet their goal.

Watsewater System

Watsewater System

Integrated Engineers designed, built, and installed a system to treat their wastewater. The system integrated existing holding tanks with a new equalizing tank where the water is mixed and aerated prior to treatment. The water from the equalizing tank is treated in a Continuous Flow Unit (CFU), where it is mixed with the FloccinAgentTM and then separated from the resulting sludge. The sludge is collected in a sludge cart for disposal, while the clean water from the CFU is directed to an ozone contact tank.  In this tank the water is treated with ozone, generated by the ozone skid, to remove any remaining organics. The clean, treated water is then ready to enter the water reuse system.

Chicken Processor

This chicken slaughter and processing facility has a wastewater system that treats 1.2 MGD.  Their process uses ferric chloride as the coagulant, caustic to stabilize the pH and an anionic polymer prior to separation in the DAF units.  The facility also does some further processing with addition of seasoning and brines which add TDS/EC to the water.  The ferric/anionic polymer combination is hindered in its ability to handle the brine water causing spikes in effluent BOD/TSS and increased surcharges.  Their treatment costs are at $2.50/1,000 gallons.

Befor and After Floccin

Before and After Floccin

Integrated Engineers, Inc. was asked to evaluate the Floccin 1105 with their wastewater.  The performance of the Floccin 1105 is not effected by the brine water.  Jar tests indicate an improvement in effluent water quality, larger floc size and an improvement in the DAF performances at the same cost of $2.50/1,000 gallons.

The Ferric/anionic water has a higher level of TDS.  The local POTW is going to start surcharging for levels of TDS for industries in excess of 500 ppm over the potable water going to the facility.  The simplification of using 1 chemical, it’s wider operating pH range and performance over the ferric makes a savings in reduced surcharges, labor, and consistent treatment.

Fruit Cannery

This facility cans peaches and pears and wanted to investigate the reduction in BOD and TSS using the Floccin Agents.  Samples were made in the off season using 2/3 by weight of peach to 1/3 pear with a total amount of 100 grams in 2,000 ml (5% by weight to simulate the wastewater generated from the facility).

The samples were flocculated with Floccin J at a dosage of 0.25 gram/1,000 ml (250 ppm), screened with coarse filter paper, and analyzed for BOD and TSS.  The results show that the Floccin J can reduce some of the BOD and a majority of the TSS.  Traditional chemistry only reduces the BOD by 8-9%.
