If it is all running off in to one trench collect it without the gravel and then you can clean it and re use the water on the golf course and playing fields. This would help pay for the costs of the equipment.
To help we would need to know the flow rate and if it is continuous. We would need a 5 litre sample of the water which we would do an analysis on to confirm that it can be cleaned.
It is possible to remove all organic and most metals from the water into a dry granular waste.
Basically we are looking to remove the surface water from building sites, primarily housing, we do this with a small trench 300/600mm wide and 1.5-2m deep with our system of drilling at the bottom of the trench
We are filling the trench with 20mm washed gravel which is wrapped with Terram
As a company we deal with surface water issues, we are being driven by the market to deal with larger volumes of water, from 3³m to 900³m
To date we have been dealing with Sports fields, so contaminants have not been a problem.
We are now moving in to the housing sector where contaminants such as Fuel and Salt from the roads can be a problem
Good morning. We have the solution for bacteria, hydrocarbons and many other contaminants. Can you describe what the contaminants involved are? mary.meyer@ospreyspillcontrol.com.
Indeed as others have commented already - more info / analytics will be necessary however I can say that we have had a lot of success with a couple different projects requiring in situ remediation - feel free to send me more info at t.thera@clean industrial.com.
Look forward to discussing some possible solutions for you.
Need more information. What are the contaminants and where do they come from . That determines what remediation efforts are appropriate. Do not approach this a s a black box issue.
If its a closed and non ferrous trench then ozone works well by disintegrating most of the solid contaminants. Ozone has been tried to reduce the TSS load. There are no residues of ozone but oxygen hence no addition in COD/BOD. Moreover the slimy layers created by microbes is a major issue in gravel trenches, such layers are killed by ozone. If it is an open trench, you can arrange simple Ozone bubbling at various points through a small pipe burried under gravel with multiple holes at small distances. This will solve your problems completely for long term without chlorine and chemicals with added advantage of reduced or disintegrated solids. No foul smell is a bonus!
Normally Cl would be used but as bacteria will use particles to be transported so a Micro filter is the way to go now as Milch is filtered in that way now and then lasts longer
