BIOLOG

The collaboration with BIOLOG GmbH was excellent in every respect. From the first contact to the final implementation of our small sewage treatment plant, we were always looked after in a professional and friendly manner. BIOLOG GmbH (especially Mr. Hirschfeld personally) impresses with its outstanding professional expertise, reliability and customer orientation. We feel in good hands and can recommend this company without reservation. A big thank you to the entire team for the excellent cooperation!

I needed a fully biological wastewater treatment plant; the conversion was mandatory in our area. I had several appointments with companies, and Biolog GmbH was the first to visit. I'm very cautious and ask questions about these kinds of things, especially when it involves larger expenses. The managing director, Mr. Hirschfeld, explained everything very well during our rather lengthy meeting and made a very good impression both professionally and personally, as well as in terms of business acumen. It wasn't a sales pitch; I didn't feel pressured, and all the options were presented. Ultimate

After eight years of significant problems with the biological wastewater treatment plant built by this company, without any solution being found and without any cooperation from management, I was now unexpectedly terminated from my maintenance contract. Promises, sales, and when there are problems, Mr. Hirschfeld is as slippery as an eel... Stay away from this company! Unfortunately, zero stars are not an option.

Excellent on-site consultation was provided, and the application process with the relevant authority was handled professionally. The system was installed neatly and quickly, and the construction site was left in pristine condition. A reliable and reputable team.

I had a very good conversation with management. Extremely competent. All my questions were answered to my complete satisfaction. I would gladly do business with them again.
