THE NATURAL SOLUTION

The sketch on below is of the overall layout of a meat and bone rendering factory that we had as a project, the purpose of this is to give some idea of how we would go about the proposal. An idea of the size of this project is given below the sketch.

The areas of concern are the storage slopes, which receive a constant supply of fresh carcasses that leave a massive build-up of body fats and greases and the level of water quality in the wet waste lagoon 3 that exits into the council sewage system.

The suggestions are as follows: 

Storage Slopes
After treating with Enzymatic (used as per directions).

Spray the slopes with a dilution of 20 to 1 Enzymatic prior to delivery and allow to stay moist, any run off will enter the system via the well and benefit the total system as Enzymatic functions in both anaerobic and aerobic systems. The purpose is to clean up the concrete slopes and control the odour from this effluent.
The temperature at the drain pit is very high (80c) as it comes direct from the cookers, this could be reduced with a cool water return from lagoon 3 at a controlled rate.

This constant use will reduce the amount of sludge build up in the two anaerobic tanks, which will in turn go through the whole system further improving the water quality.

Lagoon 3

The use of a dosing machine to control the application of Enzymatic based on the flow rate of 0.041 ML/day (as in table 20) at a dilution rate of 5000 to 1. This will require only 8.2 Litre's per day for the whole system.

Though the system is very large, the flow rate is excellent in relation to the volume of the ponds and the total retention time in the system (140 Days).  It is recommended that lagoon 3 is treated for four weeks and then the dosing should be made into lagoon 1 to control all three lagoons and reduce the algae in lagoons 1&2.

It is important that Enzymatic is not introduced until the temperature of the waste water is below 55 degrees centigrade.

The benefits gained from this will be a rapid change in lagoon 3 to meet council requirements and then the control of all three lagoons in the long term.

The two anaerobic tanks total 1.3ML of capacity and lagoons 2 & 3 have a capacity of 0.86 ML and total of 1.72 ML, Lagoon 3 has 4.6 ML.  This system is massively over engineered and has only a 0.004 ML per day flow rate, that's 40,000 Litre's per day so the dose rate is on the flow rate not the capacity.
