Remove the smallest particles from the water with a microfilter station

We use our microfilter station for the final stage of water filtration. This is modular in design and can either be mounted on a frame or integrated into a shipping container. The modules can be easily expanded. The respective customer requirements determine the needs and the type of installation. With a quartz filter, also known as a sand filter, suspended solids such as sand, cement or oxidised iron can be removed from the water.

Microfilter station – quartz filter – sand filter

The quartz filter and sand filter are very easy to operate. The filtering process takes place in a pressure vessel. Here, the quartzite is gradually saturated. Once the particles have been completely removed from the water and the sand filter is filled with dirt particles, the microfilter station performs an automatic cleaning process. This creates a water flow in the column, which helps to restore the original working conditions. The microfilter station can then start a new filter cycle. This process can be repeated as often as required.

Expansion options for sand and micro filters

Modular extension – activated carbon filter

The activated carbon filter enables carbon to be filtered. This is an absorption treatment in which organic substances or surfactants are removed from hydrogen oxidants. The absorption process also takes place in a pressure vessel. There, the activated carbon is slowly saturated. Once this has happened, the carbon is replaced. During absorption, it can become clogged with stuck-on substances. The subsequent cleaning process automatically reverses the water flow in the column. This restores the original working conditions. The now contaminated water is sent back to the first dirty water collection tank. Once cleaning is complete, the next work cycle can begin.

Modular expansion – zeolite filter

A microfilter station with the additional option of a zeolite filter removes iron and manganese from the water. There is a continuous water flow for iron removal and a batch operation for manganese removal. When the filtering process begins, the water is first pre-treated with potassium permanganate. Alternatively, sodium hypochlorite can also be used. Treating the water in the tank causes the iron or manganese to oxidise. A pump sends water to the zeolite column. In the zeolite filter, counter-current cleaning with water then takes place. In this way, it is possible to remove the filtered substances.
