Stricter environmental regulations and a need for recycling water have led to an increase in the need to filter waste water and ground water either for research in a laboratory or on an industrial scale. In both cases the water may be backlogged with moderate to heavy particulate. Some things to take into consideration when determining the suitable filter for your ground water or waste water application:
What is the sample volume being filtered?
If your sample volume is 250ml or less, a regular syringe filter may work for your application. If it is larger than 250ml your application may require the use of in-line or process filters. A standard disposable syringe filter will not be able to handle these larger volumes and may become clogged or need to be changed out frequently during the application.
Do you require a pre-filter?
It is important to determine the amount of particulate in your water. If the water is heavily saturated with large particulate, you may need to consider the use of a pre-filter to extend the life of the membrane or increase the flow in the filtration device you decide to use. Depending on your sample volume, Tisch Scientific manufactures GD-4 syringe filters which come with multiple pre-filter layers built into the syringe filter, these may be an option for you.

Common types of membrane materials used in ground or waste water applications:
Glass Fiber Membranes prove to be very useful as a pre-filter for heavy particulate laden samples which makes them another optimal choice for ground or waste water filtration. Glass Fiber Membranes can be used as a prefilter with another membrane material or they can be used on their own.
