Targeted customers for SplitBox® Leachate are primarily landfill owners and operators. These customers, both public and private, are all faced with the similar problem of treating and disposing of leachate for a reasonable cost. now and well into the future.
Regulators often suggest that leachate should be pumped to a sewer for treatment at a urban wastewater treatment plant (WWTP). However, this may historically have been driven by concerns that leachate treatment on site is challenging and difficult to achieve reliably, than by a detailed appraisal of the best options available. This however is changing and increasing pressure and emphasis is being placed on local treatment solutions.
It is not generally a good policy to treat strong leachate from modern sanitary landfills after discharging it into sewer, mixing it with sewage. Leachate has an extremely high ammoniacal nitrogen ("ammonia") concentration when compared with the much weaker contamination levels in domestic, commercial, and industrial foul sewage. Treating strong leachate at a UWWTP, as if it were sewage, is inefficient and unnecessarily costly. Unless the UWWTP has a highly nitrifying type process, one of the most potentially damaging types of contaminants in leachate may simply be diluted by the weaker strengths of those contaminants in the sewage, and not treated.
There appears to be a significant push by regulators to highlight the need to consider onsite treatment solutions. Biotain agree and believe the treatment at source to be the key to effective leachate management. Biotain have developed a solution for treating leachate on site reliably, without dilution, which is available today. Which produces a very high quality effluent, which will then be capable of discharge either to a sewer with greatly reduced volumetric charges, or directly to a watercourse.
Our on site leachate treatment solution is not only more environmentally sustainable than off-site treatment, but will typically have a lower operating cost for the site per cubic meter, and most importantly are not nearly as subject to future unknowns like: rising volumetric charges/levies, and possible withdrawal of sewage discharge consents.
