The prefab storage tanks and cover systems of ISS Tanks are suitable for storage problems where the economy, safety, productivity or environmental considerations require a well-thought-out storage solution.

The prefab bolted, glass coated, epoxy coated and stainless steel storage tanks and covers are designed to store a wide range of materials ranging from plastics and chemicals to minerals and foodstuffs. Superior coating technologies enable us to provide storage tanks in a wide range of municipal, industrial and agricultural applications.


There is a waste water tank for the storage of industrial waste water. The water can be collected for purification.


The drinking water tank is suitable for pure water for consumption. These tanks can be supplied in various materials.


The anaerobic reactor is widely used in water purification plants. Anaerobic wastewater treatment is a process in which bacteria in the absence of oxygen convert organic matter into the water into biogas. This happens in the many anaerobic reactors of different dimensions are applied. They can be applied in many versions. Gas/Water separators from the customer can be mounted during construction


The FM sprinkler tanks are made of galvanized steel sheets with an epoxy powder coating. ISS tanks supplies the sprinklertanks with FM approval. The sprinklertanks are provided with:

  • Suction connection with Vortex
  • Drain with Valve
  • Gradient connector
  • Test return connection, fill in connection, heating element
  • Manhole in Tank wall and roof, Cage ladder.

The tanks are mounted by specialized, construction teams under the supervision of ISS tanks.


The sludge tanks are designed to keep the contaminants in solid shape and to settle them to the soil. They are installed with heating systems for heat exchangers or other heat automation elements.

The sludge tanks can also work with local water supply systems, which are equipped to remove for example iron (by means of sand filters) and thus the next step of the purging of waters


In a digester biomass is converted into gases.  The fermenter is a tight, insulated, heated and stirred tank, in which biogas is extracted from the biomass. The supply of the substance to be fermented is constant. The heat exchangers in the wall keep everything on temperature. The biomass can be stirred at simultaneous times by means of mixer in the top of the roof hanging in the digester.

At the top of the fermenter is the gas storage. For larger fermenters we place an after-storage. In this after storage tank, the remainders are released biogas.


In a settling tank, the first rain on which contains the most organic material. Because these dust and particles are heavier than rain and water they will have the chance to sink down in time. This initial filtration causes less sludge to be present in the tank.

The water in the sedimentary tank is not suitable for human use.


In an aeration tank, air is blown through the waste water, so that a lot of oxygen is released into the water. By means of this oxygen the bacteria will break down the waste into the water. The water uncovering and foams at the time of this aeration.

This means that a biological breakdown takes place in the water.


In the neutralization tank liquids are contained within that are alkaline and/or acidic. These are neutralised in the neutralization tank and brought back to a neutral pH value.
