Case Histories
CASE NO. 1:
Seven years ago, a paper recycling company approached Aries Tek Ltd. for our help. The paper company was discharging 300,000 gallons of waste water per day into the city sewer, costing the company $1,500,000 on an annual basis. They had purchased an induced air flotation unit, and wanted Aries Tek Ltd. to set up a chemical treatment program. Upon inspection, Aries Tek Ltd. discovered that their present induction aerator produced excessive energy, breaking up the flocced solids. Aries Tek Ltd. replaced the induction aeration system with a dissolved air system, reducing the polymer costs by 30%. Aries Tek Ltd. also completely automated the polymer feed system, reducing the polymer costs another 10%. The system was redesigned to recycle both the waste water and waste paper. The paper recycling company presently has zero water discharge, and realizes an annual savings of $1,750,000.
CASE NO. 2:
Having problems meeting their discharge limits for chromium and sulphides, a leather finishing company contracted Aries Tek Ltd. to upgrade its existing small, antiquated water treatment system. This included increasing capacity to 400,000 gallons per day, and completely automating the process control system which was designed to be computer controlled by a single operator. Discharge levels are presently well below the limits of 3.0 ppm chromium and 0.15 ppm sulphides.
CASE NO. 3:
A national ice cream manufacturer faced similar problems and could not meet the city discharge limits for “oil & grease”, as well as “total suspended solids” at one of their plants. Aries Tek Ltd. installed a new dissolved air flotation system and completely automated the waste treatment system, including the chemical feed system, and pH control. They are now operating well within the city discharge limits.
CASE NO. 4:
Local officials were threatening fines of $250,000, and charging $12,000 - 15,000 per month to a large Japanese company that makes rice flour for export to Japan. Exceeding the city’s discharge limits, this company was discharging waste water containing 15,000 ppm BOD and 200 ppm TSS. Aries Tek Ltd. was contracted to design a complete treatment system, including clarification, biological treatment and sludge dewatering. The system was designed to discharge up to 20,000 gallons per day with limits of 400 ppm BOD and 200 ppm TSS. The system is totally automated, requiring only 1-2 hours per day of operator time and the present discharge levels are 10-20 PPM BOD & \ PPM TSS.
CASE NO. 5:
Aries Tek Ltd. was also contracted by a trucking company that had installed a specialized sanitizing system for cleaning bulk trailers used for hauling food products. Since there is no sewer system at the trailer wash location, they spent $60,000-- $80,000 per year hauling the waste water to the city sewage system. Aries Tek Ltd. installed a dissolved air flotation system, incorporating existing tanks and piping to clean the waste water. The system is completely automated, including chemical injection, requiring minimal operational attention. The company is recycling their waste water for land irrigation.
CASE NO. 6:
Not able to meet the specified discharge limits for oil and suspended solids, a fish processing company contracted Aries Tek Ltd. to design and install a waste water treatment system. The system incorporates a 300 PPM dissolved air flotation unit and is completely automated. The company is presently meeting its discharge limits.
CASE NO. 7:
A Leather Company, was disposing of waste sludge at 5-8% solids to a city disposal. The city required that the company must dry their waste sludge to greater than 35% solids before they were allowed to discharge it to the city disposal. Aries Tek installed a 25 Cu.
