Vast improvement in operations of a WWTP at plastics recycling facility through use of bio-bacterial waste water treatment and plant equipment upgrades.
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.
Approach
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.
