A pilot study was conducted at McAllen, Texas to evaluate two microfiltration technologies, Memcor and ZeeWeed, to treat secondary effluent from the city of McAllen south WWTP. The objectives of the study were to compare the ability of Memcor and ZeeWeed to pretreat secondary effluent for subsequent processing by RO and to evaluate the ability of the ZenoGem membrane bioreactor process to directly treat screened, de-gritted wastewater to a quality suitable for direct processing by RO. The results showed both Memcor and ZeeWeed to be competitive in their ability to produce a high quality filtrate from secondary effluent. The results also indicated that the ZenoGem process is capable of producing a filtrate suitable for RO treatment while meeting the City's current wastewater effluent discharge requirements. Additionally, the ZenoGem treated McAllen's raw wastewater to a quality comparable to the city's existing WWTP effluent.

Chlorine Demand

Increased levels of nutrients and pollutants are expected in the Inanda Dam (KwaZulu Natal, South Africa) as a result of wastewater effluent discharge, informal settlements and agricultural runoff in the catchment. Contaminants of atrazine and 2-methyl isoborneol were dosed into the feed water of a granular activated carbon (GAC) pilot plant to assess the performance of different process options for the treatment of Inanda Dam water. It was found that the use of ozonation and GAC did not result in increased levels of biological activity as expected. The use of ozone in conjunction with GAC is however recommended as significant benefit was obtained in the reduction of UV absorbance, chlorine demand and concentrations of other microcontaminants.
