H&A offers complete digester and tank cleaning services. Over time, digesters accumulate grit, trash, and heavy solids that are not removed during normal wasting events. This accumulation reduces effective treatment capacity of the digester and negatively effects proper operation. H&A can safely and efficiently remove and manage these solids.
H&A can also remove heavy accumulations in oxidation ditches, aeration tanks, etc. These cleanings are performed so that these structures can be serviced and to provide additional storage and treatment capacity.
All H&A personnel are confined space trained. All operations are conducted in compliance with local, state, and federal regulations.
