Te-Tech’s te-saf™ submerged aerated filter has come to the rescue at Southern Water’s Leeds WTWs in Kent. The works treats wastewater from the surrounding villages and from the popular tourist attraction Leeds Castle.
When a new and tighter nitrate consent was introduced to protect the environmentally sensitive River Len, Southern Water’s framework contractor BTU approached Te-Tech Process Solutions.
Te-Tech was able to offer a te-saf™ unit for immediate deployment on a hire contract while Southern Water engineered a permanent solution. With logistics and cranage coordinated, the plant was installed and ready to go within hours of arrival on site together with its self-contained, portable control skid which houses the blowers and control system. In a matter of a few days, the te-saf™ was achieving 70% reduction in ammonia improving the site’s compliance.
