Filtration - MRWA

Filtration can be compared to a sieve or micro-strainer that traps suspended material between the grains of filter media. However, since most suspended particles can easily pass through the spaces between grains of the filter media, straining is the least important process in filtration.

Cloudy - Turbidity - Well Water Treatment Systems & Filters

Depending on the nature of the turbidity, a backwashing sediment filter using a special type of zeolite filter media does a great job at clarifying water. Sediment down to the 5 to 10 micron range can be removed, and then backwashed out periodically by the automatic control valve.

Turbidity Water Treatment and Turbidity Water Filtration

Turbidity refers to how clear/cloudy the water is. Turbidity in water is caused by suspended matter, such as clay, silt, fine particles of organic and inorganic matter, and microscopic organisms. The more total suspended solids in the water, the murkier it seems and the higher the turbidity.

Gravity Filtration Systems - Napier-Reid

In rapid gravity filtration the particulate impurities are removed in or on the media, thus causing the filter to clog after a period. Clogged filters are cleaned by backwashing. Backwashing: Is the process of reversing the flow of water through the filter media to remove the entrapped solids.

Optimizing Your Plant’s Filter Performance

Most operators wash filters at a preset run length, loss of head, or effluent turbidity limit. At some point in the filter run, a filter will begin to pass turbidity (if allowed to continue). Before that time, the effluent particle output will increase. Particles the size of Giardia cysts and Cryptosporidium oocysts may pass without any discernible increase in effluent turbidity.

Water Treatability Database | US EPA

The duration of slow sand filters runs depends on water quality and loading rates. Ideally, the raw water turbidity should be less than 10 NTU. With low turbidity in the influent water, the filter can be operated for a period between two weeks and three months.
