PROJECT DESCRIPTION

Back Ground

• In November 2016 Bactech (a Waste Water Division of Bio Natural Solutions - BNS) was asked to inspect the WWTP at a plastic recycling facility.
• The plant was experiencing severe odour issues and had a build-up of sludge in the primary treatment tank.
• Although the plant was designed to be able to recycle and reuse its wash water, this was not possible due to the pollluted nature of the water.
• This resulted in the company having to import 9600 litres of potable water per week, as well as discharge a similar amount to the sewer.
• In an attempt to soften the water, the were also using $5000 of Alum per annum.

Approachstrong>

• Having inspected the system, BNS ascertained that the system was a suitable candidate for treatment with Bactech 362.
• A weekly dosing schedule was proposed and agreed upon.
• A recommendation was made and implemented to double the capacity of the system through the addition of another 3000 litre tank.

Outcome

• Within 3 days, the noxious odours had been eliminated.
• Within 3 weeks the sludge already present in the system had been digested.
• The plant is now able to recycle 100% of its wash water, reducing the amount of potable water being imported to 80 litres a week.
• Alum is no longer required.
