The Surface Water Treatment Rule (SWTR) has impacted many small systems such as Toms Brook which use groundwater as their supply source. They either rely on springs or wells for their supply. Membrane technology has emerged as a viable solution to the problem created by the SWTR. Basically, a mechanical filtering of the bacteria and other organisms takes place. The water is then disinfected with chlorine to kill viruses that are not mechanically filtered. The proposed membrane technology is considered microfiltration technology. It provides direct filtration of Giardia, Cryptosporidium and other bacteria. Some direct filtration of viruses occurs, however, disinfection will be the primary means of this removal. The filter membranes are periodically backwashed to remove the particle buildup. The operation of this filtration is totally automatic and requires only periodic monitoring by the existing operator. A pilot study was conducted to evaluate the ability of the Memcor 60M10 filter unit to treat the raw water source and comply with the requirements of the SWTR and Virginia Department of Health Waterworks Regulations. The construction of the new water treatment plant will allow the Sanitary District to more than adequately supply their customers with drinking water of the highest quality. The simplicity of the system along with its low operating cost compared to conventional treatment means will help the authority hold down the needs to increase their water rates which are already the highest in the area. Also the automation of the system has allowed the authority to operate and expand their treatment capabilities without having to add additional operators.
