Food manufacturing and processing operations have made huge strides in cutting their environmental impact, cleaning up or reducing the effluent and wastewater they produce.
Of course, it makes good business sense. But it’s a problem that isn’t going to go away and with increasing trade effluent charges and disposal costs, it’s an ever-present issue.
Take the bakery sector. Despite dietary pressures to cut fat and sugars our fondness for bread, cakes and pastries is unabated. Indeed, it’s a massive market producing millions of products each day to fill the supermarket shelves.
But as a food process industry it is also one of the largest water users, by far the biggest proportion of which is used for wash down and cleaning purposes. Loaded with fats, flour, sugars and yeast, treating this prior to discharge is essential to meet increasingly stringent environmental consents.
This is a purpose built self-contained reactor which is plumbed in to the company’s existing effluent treatment system. A small footprint is especially advantageous and it relies on the Advetec micro-organisms to reduce the organic content within the effluent.
It can achieve this at an accelerated rate and without the peripheral storage and balancing tanks that traditional systems require.
This is achieved in part by ensuring a waste flow through the Bio-reactor that constantly mixes and aerates the effluent, preventing suspended solids from settling out and maintaining dissolved oxygen levels.
This maximises the digestive effectiveness of the system. But it is the company’s use of specially developed bio-stimulants that invigorate indigenous bacteria within the waste stream that makes the difference, an area that Advetec has specialised in. These bio-stimulants are matched to individual waste streams following laboratory testing, which significantly accelerates the process and delivers more effective reductions in organic concentrations.
The main tank and mechanical components are constructed with 316 grade stainless steel to provide the necessary corrosive resistance to varying pH levels typical of bakery industry wastewater, and system monitoring with automatic dosing ensures an optimal internal environment for the process.
As well as a small foot print, the system also requires minimal maintenance, providing the composition of the effluent flow leaving the factory remains consistent and within design parameters. This is important and one of the reasons waste stream sampling and testing is crucial explains Advetec’s chief operating officer, Richard Goff.
Other than that a monthly check that dosing pumps and air compressors are working satisfactorily, and to monitor the level of micro-biological media in the dosing system, little intervention is required.
