INDUSTRIAL TRADE EFFLUENT
Why treat your industrial wastewater on-site?
With the regulatory environment for industry becoming significantly more complex, industries are finding it more difficult to keep up to date with effluent treatment technologies, and usually Process Managers do not have the time to spend on the more detailed areas of wastewater treatment. Pollution Control can relieve this burden by advising on the processes for them. Our engineers have knowledge of industrial processes and available treatment technologies, such as the EcoSAF or an SBR system to deal with the wastewater problems of a particular plant and can provide clients with the optimum solution. These can be tailored to the particular industry/effluent offering considerable operational cost savings, as well as freeing up staff who would otherwise be resolving these problems.
Pollution Control appreciate that management involvement is essential to ensure an inclusive and consultative approach is maintained with the client and particularly with the operational staff who will be required to run any new processes.
Pollution Control is able to identify technologies and processes most suitable to a particular effluent and to quantify the problems on a case by case basis. Analysis of the nature of the effluent, how the effluent is produced and the current processes used all helps with the decision as to which solution would be more appropriate for your effluent treatment.
The benefits normally achieved include:
- Substantial savings in trade effluent charges
- Recycling of sell on by-products
- Long term legal compliance
- Low capital cost and rapid investment payback

The following example of the potential savings that can be made is taken from a current Pollution Control (UK) customer:
YOUR TRADE EFFLUENT BILL
Trade Effluent and Measured Sewerage Charge
|

|
||
|
Trade effluent charge - Calculated as per consent |
||
|
Formula: C = (R + V + M + B1) + (Ot/Os x B2) + (St/Ss x S) R=17.6p B=2.1p Ot=2485mg/l |
The above bill is your actual bill for July 2007. Untreated sewage would be charged at 146.86p per m3.
Most of the above charges are fixed, however by reducing the COD (Ot) and suspended solids (St), prior to discharge, you will be able to significantly reduce your annual charges.
Basic treatment of your effluent onsite prior to discharge can reduce Ot and St by 65-80%.
The simplest way to determine how the budget should be spent in terms of treating COD and suspended solids, is to work out what effect a theoretical drop in either would do to the charge.
We are assuming an 80% drop of each parameter (which is very achievable), and the July flow of 2400m3.
YOUR TRADE EFFLUENT BILL
Trade Effluent and Measured Sewerage Charge

|
Trade effluent charge - Calculated as per consent |

Formula: C = (R + V + M + B1) + (Ot/Os x B2) + (St/Ss x S) R=17.6p B=2.1p Ot=497mg/l |
The above bill assumes an 80% reduction of suspended solids and COD.
Assuming the flow is constant at 2400m3, the charge would be
56.48p per m3.
This results in the total charge dropping from £3524.64 to £1355.52.
This would result in a saving of £2169.12. A drop of nearly 62%.
Annual savings would be £26,029.44.
Even if COD and suspended solids were only reduced by 65% each, the
annual saving would still be £21,147.84 HALF the current annual bill!
